Well well, others would agree that you are not responding to my posts in anyways. In my opinion China does need and should have better deals with Russian engines but the PLA politicians make the decisions.

There are two mistakes in your information:
1) WS-9 is a modified Spey Mk202. It reduced fan+compression from 17 to 14 stages. Different burner, nozzle, 500kg more thrust and so on. Are you not able to tell different definitions of copy and development?

2) CAC has nothing to do with WS-15 that is not a 17 ton engine.

You have merely shown that you have limited information about China's defence industry and that you are irrationally biased.

I am responding to you just fine.

500kg??? :sarcastic: That's funny. Spey Mk202 gets 20,500lbf and WS-9 gets 20,515. There is a 7kg difference in thrust which shows it is an illegal production.

2) CAC has nothing to do with WS-15 that is not a 17 ton engine.
CAC is developing the J-13 which is the likely prototype for J-XX considering Shenyang doesn't even know how to tie their shoes. It is supposed to be powered by WS-15 and according to Chinese sources is an "F-22 class" engine which would be 17.5 tonnes. Keep up please...

You have merely shown that you have limited information about China's defence industry and that you are irrationally biased.
Speak for yourself. You haven't shared one iota of factual information in your posts.

Are you ever going to post the WS-15 information?

500kg more thrust! Good find. China paid for every piece of paper about MK202 tech. Can you tell difference from a tot deal?

CAC's engine project was abolished. WS-15 is less than 17 tons with a primary thrust weight ratio between 9-10.

Speak for yourself. You haven't shared one iota of factual information in your posts.

I am not indebt to share anything with you since you are so biased. The WS-15 project has gone so well (better than WS-10A process) that passage of every milestone has been officially announced either on AVIC web or in the newspaper called "Aviation News".

You are saying China could not even copy MK202 and yet Russia is afraid of AL-31 being copied. The real reason is Russia does not want to assist China to develop fighters too quickly. Without a powerful engine the fighter performance will be seriously downgraded. For instance J-10B is heavier and needs more power than that of AF-31FN or M1 variant. If Russia refuses China has to continue on its own by all means. It does no good to anyone.

vladimir !watch out! They may chinait more perfectly as they have already chinawed so many russian things...who cares? A working engine is always welcome. who cares whether it resembles AL-31 or not? we are not doing that..neither designing our own nor copying...beg,borrow,steal...anything is acceptable in the industry..especially defence industry..can your govt enforce chinese govt on IPR violations for outright copy of SU-27 to make J-11 and take them to task like the Americans did to Israel in the ninties for making LAVI which was an improved clone of F-16? will russia be able to take the chinese to international court of justice? you will be wasting your time! i am not sure intnl court of justice handles such cases!

What can Russia do about pirated weapons? Make the offending parties sign IP agreements. We have already pushed on the AK-47, RPG-7, and D-30 patents and gotten China and Pakistan to take their copies off the export market. Why have the acquiesced? Because we hold the key for their airforces. Without our engines, PLAAF and PAF don't fly. They don't have any choice but to obey.

In a economics term ,Russians are stranded.

When Chinese have their own backups, Russian find that they have no much choice but to keep on the status quo,until CHinese mature their tech and abandon Russian ones.

it is just a matter of time that Chinese catch up with Russians as for aerospace tech,when CHinese can invests much more resouce on R&D than Russians.

BTW, it is reported by Janes defence that Chinese mayby are developing two 5G bird projects at the same time independently,while Russian crappy economy hardly support one 5G bird projects ,even with the financial support from INdia.

I am laughing at this thread of all the Chinese guys posting on this forum arguing with Vladimir that the WS10 is not a copy of the AL31.

What is really funny is that exhibition pic where they put both engines side-by-side to prove that they werent copying !!

Isnt it amazing that the Chinese developers were thinking of the same thing ??

Its almost like as if they were saying - "Here they are guys "side-by-side", So you see how it doesnt have the same number of blades and the colour of the metal is different, and the external piping is routed in a different way.

Now you can see we did not copy the Russians "


LOL.......China has a PhD in copying technology....so much so that even if you develop something original, no one is going to believe you.

Too Funny....Guys !!!

This is the real face of Taihang (WS-10) Turbofan Engine!|China Military Power Mashup ??
he abandon of WS-6 project did do not mean that China gives up independent aircraft engine manufacture. In 1980, China started to implement a plan, High Performance Propulsion System Preliminary Development (HPPSPD), to focus on basic research on engine components. March 29th 1982, US famous “Aviation & Space Technology Week” had a report with title of “China Waiting for CFM-56II Turbofan Exportation”. The report said that China purchase 2 CFM-56II Turbofan engines to exchange China’s Trident airliners’ old ones. U.S. DOD (Department of Defense) worried about this exportation, because CFM-56 is based on the core of the F101-GE-102 engine which was used in B-1B Lancer Bomber. Despite of the dissidence, U.S. government still authorized this exportation in 1980s’ Sino-U.S. HoneyMoon Relation. Actually, some resources from China showed that the development of WS-10 just bases on the core engine from CFM-56. And WS-10’s final object, is F110 engine. WS-10 project got directly supports from top leader of China. In January 1986, Deng Xiaoping passed a new plan on China’s Turbofan engine development. One year later, 606 with its attached department formally initial the development of WS-10, code name Taihang, for China’s third generation fighter J-10.

In 1989, after almost 10 years’ preparation, WS-10’s core engine project started. June 12 1989, Chinese aircraft engine manufactures received the order of “3 core test components of HPPSPD ” In July, a conference of “Three most Important Parts of High Pressure compressor” was held in 624 institute. These three parts include: 7-stage high pressure compressor, short annular combustor with air blast atomizer and air film cooling blade. With out these main parts, China’s future core engine can not be resolved. In future, the core engine will be able to become a medial thrust & small bypass ratio turbofan which is 8 in thrust to weight ratio. In China aviation industry, this core engine was called as Medial Thrust Demonstration Turbofan Core Engine, MTDTCE.

Central Banque forcasts 4-5% GDP growth next year. I wouldn't call that stranded when EU will be posting 1%.

When Chinese have their own backups, Russian find that they have no much choice but to keep on the status quo,until CHinese mature their tech and abandon Russian ones.
While it certainly pains us to lose a lucrative arms market like China due to their IP theft, China is shooting themselves in the foot in two ways. 1) they are copying obsolete technology that by the time they field it is two generations behind and 2) they can no longer export without buying long overdue license from Russia.

it is just a matter of time that Chinese catch up with Russians as for aerospace tech,when CHinese can invests much more resouce on R&D than Russians.
How can China catch up with Russians when all they do is copy obsolete hardware that takes them three times as long to produce than it did the actual developers?

BTW, it is reported by Janes defence that Chinese mayby are developing two 5G bird projects at the same time independently,while Russian crappy economy hardly support one 5G bird projects ,even with the financial support from INdia.
It is reported on the PLA website J-XX is nothing but a J-10 upgrade. You do not compare to Russian aerospace technology. Our bankrolled projects are the same thing done in the US. You think F-35 is only paid for by Amerika? :sarcastic:

guy, "growth" is not naturally equal to "development".

Instead, "growth" based on export of petrol just means "S-Arabianized".

Frankly speaking, If Russians can not stop its tendency of "S-Araibianization", Russia would just become another "Canada" in the eyes of CHinese in one decade.

BTW, Canada's population is about 1/10 of USA's.and Russia's population is also about 1/10 of CHina's.


Russian should get used to the current world....Russia is not USSR ,and it is not a superpower any more.
however, I find many Russians seem to still live in the cold war era .

You think Russia is going to wait for China to "catch up"? China is too busy reverse engineering old technology instead of actually putting fourth the effort to creat new and inivative technologies. It takes alot of time and money to reverse engineer technology. Consiquently, little knowledge is gained from reverse engineering.

Even the J-10 used Russian and Israeli engineers, not to metion the Chinese had access to the Lavi.

Do you have any idea how far back China would be if they had no Russian technolohy to copy? With that being said, Chinas's "5th gen aircraft" will hardly be indigenous. Similarly, to the J-10, Russian and Israel technology will find its way in to the J-XX, and as usual China will hire Russians to help them develope their 5th gen aircraft.

China is in over her head with the 5th gen project. The Chinese have built scale models for wind tunnel test, only problem is they had canards!!! I guess somebody forgot to tell the Chinese that canards have terrible stealth qualities.



The Russian econmy was one of the fastest growing before the world economic crisis. The Chinese economy is large, but not glamorous, let me explain why: 1.) Most people work at sweat shops, and many companies from around the world move their factories to China because of cheap labor. 2) Communist have deep pockets. 3) China has a population of what 1.3 billion?

Having one of the largest navies, airforces, armies, nuclear stockpiles, and a seat on the UN security council constitutes as a superpower.

Typical russian bullshit, Do you have any evidence of canards that will aftect stealth qualities? i want figures instead of quoting from american bullshit. :twizt:

well, this month, the deputy commander of PLAAF decalred that Chinese 4G bird will fly soon while Russian declare that Russia 5G bird suspend its first flight....

Don't you feel the two cases are very ironic and is stone-cold ?

3 years ago ,nobody thought that Chinese JXX might fly before Russia 5 G bird, Just as if 3 years ago nobody thought that Chinese GDP could surpass Japan before 2010.

No offend. in my eyes, Russia is not standing still,but "going down"...Its oild-based economy is skewing its other industry sections.while its oil industry sections receive heavy investment, its other industry sections keep on shrinking .

Even if China were to stand still, Russia would skew its industry chains left by Soviet .

Russia is no longer as strong as it used to be in the Soviet times. You don't need to wait for Chinese and China has already surpassed you in some of the tech areas. Your dreamed superiority is illusive.

Do you have any idea how far back China would be if they had no Russian technolohy to copy?
No idea what you are talking about. If you exclude those tech China has bought from Russia you tell me what the copies are. Please don't claim what is from your grandi times.

With that being said, Chinas's "5th gen aircraft" will hardly be indigenous. Similarly, to the J-10, Russian and Israel technology will find its way in to the J-XX, and as usual China will hire Russians to help them develope their 5th gen aircraft.
Those Russian engineers are job seeking immigrants hired by Chinese government. It's a shame that Russia can not keep those skilled workers and it's obsurd that you claim credit for the Russian tech. One should thank China for offering jobs to them in doing what they have been educated for.

What has Israel got to do with Russian flag?


China is in over her head with the 5th gen project. The Chinese have built scale models for wind tunnel test, only problem is they had canards!!! I guess somebody forgot to tell the Chinese that canards have terrible stealth qualities.
You should check your text book or ask your professor to learn how canards would interfere with stealthness. No wonder why Russia is already bit backward when it comes to the aerodynamic design of the next generation fighter.


The Russian econmy was one of the fastest growing before the world economic crisis. The Chinese economy is large, but not glamorous, let me explain why: 1.)

You should pray for the oil price on a daily basis, because that is the only solid support for your economy.

Control conards have poor stealth characteristics

Canard (aeronautics)

Aiming at to reduce the RCS of the aircraft, the designers of the T-10 (Sukhoi) had opted to remove canards from the aircraft

Su-35BM (Bolshaya Modernizatsiya - Big Modernization)





The two illustrations above are basic radar behaviors upon planar surfaces.

Corner reflectors are like beacons and they are useful in coastal marine safety as they amplify small boats on a radar scope.

Safety Reflector

Quote:
These 12 1/2" dia. reflectors are very common on many cruising boats. All models can be stored flat and assemble in minutes. Plates are held together by tough, injection molded corner latches. Assembled reflectors include a 1 1/4" (32mm) windage hole for reduced aerodynamic drag, which also allows for backstay mounting. Standard Echomaster: 13.2 square yards (12 square meters) of radar cross section in the 9-9.6 GHz X or 3cm radar band.

So as we can see that a corner reflector not much larger than hand span can create an RCS of 12 square meters in the bands that most military radars uses, including the missiles themselves.



And that is how the aircraft itself can become a corner reflector, a huge 'no-no' in RCS reduction.

This image has been resized. Click this bar to view the full image. The original image is sized 1023x639 and weights 44KB.


That is the XB-70. Its design exploit the 'compression lift' principle to Mach cruise. Essentially, the body sort of 'surf' the Mach wave the aircraft produces. You can read up on the principle here...

Aerospaceweb.org | Hypersonic Waveriders - Vehicle Characteristics

But in order to exploit compression lift, the design ended up with many corner reflectors as shown with the wing tips and CANARDS. The aggressor radar from below illuminating the bomber will have its radar signals returned to it from the canard corner reflectors and the bent wings. It is bad enough that the wings themselves can reflect radar signals if the approach angle is 'just right' so why compound the problem with canards?

That is not to say that canards 'cannot' be on a body. It simply means that canards present extraordinary RCS issues to overcome. If they are control flight surfaces, their movements will create 'radar scintillations'...

Scintillation (radar) - Wikipedia, the free encyclopedia

Quote:
This effect can be caused by a shift of the effective reflection point on the target, but has other causes as well.

The 'shift' is the movements of the canards as they maintain flight stability, steady or in maneuvers. Other types of radar scintillations, or 'shifts of reflective' points, are main and tail helo rotors. Ballistic missile warheads descending through the atmosphere spins to maintain stability and because the warhead body is not uniform with fins and nozzles and whatever else, those surface imperfections also create radar scintillations.



Those are scatter points on an aircraft. That is how a radar sees a target -- collections of scatter points. A statistic algorithm, and there are levels of complexity for these algorithms, will determine if these scatter points are persistent enough over time, distance and cluster and will display a target. A pair of scintillating scatter points ANYWHERE in that cluster is a giveaway and improperly designed flight control canards will negate any RCS reduction on the rest of the body. This is why I chuckled every time I read some Russian and Chinese junk fanboy's comment -- Oooohhh...Aaahhh...Canards...Coool....

The USAF heartily encourages potential adversaries to install canards on their fighters.

Clear as mud?

Source: Gambit

well, this month, the deputy commander of PLAAF decalred that Chinese 4G bird will fly soon while Russian declare that Russia 5G bird suspend its first flight....
Big differences between a 4G and a 5gen...

Russia didn't suspend anything. The first flight of the Pak Fa should be sometimes after newyears; Russia already has three different prototypes.

So if the Chinese bird flys first does that mean it's better than the Pak Fa? Simply put, NO! The ugly reality is the WS-10 is plagued with problems, and Chinese avionics are just not very good. Much of the Pak Fa's avionics are complete, Russia already unvailed several AESA radars...where is China's AESA? Simply put, China may very well test the J-XX before the Pak Fa, but atleast the Pak Fa will have 5G avionics, the J-XX, on the other hand, will likley have 4G avionics by its maden flight.


3 years ago ,nobody thought that Chinese JXX might fly before Russia 5 G bird, Just as if 3 years ago nobody thought that Chinese GDP could surpass Japan before 2010.
The J-XX hasn't flow yet, so dont get too happy. And again even if it does fly i'm not worried. The fact that the Chinese actually tested conard mock-ups showes their lack of knowledge in basic stealth concepts...


No offend. in my eyes, Russia is not standing still,but "going down"...Its oild-based economy is skewing its other industry sections.while its oil industry sections receive heavy investment, its other industry sections keep on shrinking

Like i mentioned earlier Russia's economy was growing at an incredible rate before the world economic crisis. It's a matter of time before the economy is back where it left off.

What areas? The day China will stop purchasing Russian technology is the day i will beleive you. Oh btw how is the WS-10 comming along? Thats right you just ordered more AL-31's, so much for surpassing...


No idea what you are talking about. If you exclude those tech China has bought from Russia you tell me what the copies are. Please don't claim what is from your grandi times.
Type 69, type 56....this will take all day but Chineses engines, Chinese radars, Chinese everything is copied from Russia. There is a reason Russia refused to sell the SU-33 or more SU-30MK-2's to China.

Even Americans know China pirates Russian technology...

China has been buying and adapting Russian naval technologies as it introduces new ships to the fleet in fits and starts. Instead of standardizing ship designs and deploying large numbers of similar ships to its emerging blue water fleet, the People’s Liberation Army Navy keeps introducing new types of guided missile destroyers largely in pairs. The answer to the question of why China produced only one or two of four recent new guided missile destroyer designs could be that China is trying to gain the capability of producing a 956-type ship so that no more expensive Russian imports would be needed.
Russian officials have been irritated for years by what they view as China’s illegal reverse engineering of combat systems. After selling a few systems to China, Russia had counted on follow-on orders for more systems, which is the ethical business practice of other nations. In addition to costing Russia the loss of future sales to China, Chinese copies compete with Russia in sales to other Third World navies. China in turn has complained that Russia has overcharged it for ships and systems that were sold for less to other nations.

The Russian state military import/ export agency Rosvoorouzhenie and 956E production Severnoye Design Bureau were shocked and angered when the 054A upgrade to the new People’s Liberation Army Navy (PLAN) 054 frigate appeared in 2006 (SIGNAL Magazine, May 2007). At first it appeared to have four Russian-supplied systems that had been on earlier Chinese Luyang guided missile destroyers (DDGs). In reality, the four complex systems were illegal Chinese copies never before seen, and all were on a new serial production series of frigates. This was the straw that broke the bear’s back, and it could result in Russia shifting high-technology exports from China to India.

Russian military exports to China peaked in 1996 at 70 percent. By 2006 this had dropped to 40 percent, and in 2007 the exports dropped by half to 20 percent. Other factors may be involved, but Rosvoorouzhenie dissatisfaction with the loss of expected future sales is certainly apparent.

Chinese Premier Hu’s March 2007 visit with top-level Russian officials on new military cooperation programs reached no new agreements. This contrasts with previous meetings that announced large new Chinese military purchases. An expected order of an additional Su-30MK2 aircraft did not happen. However in 2007, India signed for 40 additional Su-30MK1 fighters from Russia.
The Sovremennyi high-technology combat systems copied by China on the surprising 2006 054A upgrade may seriously disrupt future high-technology imports to China by Russia. The four copied systems are the MGK-335 sonar, the Fregate M2EM three-dimensional (3-D) radar, Mineral ME (Bandstand) tracking radars and the Russian MR90 missile guidance tracker-illuminator for the SAN-7 Rif-M Shtil surface-to-air missile (SAM).
Designed by Morphizpribor Central Research Institute, the complete MGK-335 sonar suite has a towed variable depth sonar (VDS) in addition to its hull array. Because no stern VDS hoist is visible, the Chinese 956E ships must have the reduced MGK 335MS with only the hull sonar dome. This complex 1.5-10.9 kilohertz medium-frequency sonar has sufficient power and digital signal processing to enable near-convergence zone detection capability. The first PLAN vessel to use an imported sonar set was the 2002 052B DDG. The 054A frigate in 2006 was the first illegal reverse-engineered version manufactured in China.
The Fregate M2EM 3-D radar offers two channels in E and H bands that can track more than 100 contacts with maximum range of 300 kilometers (200 miles). The equipment and antenna weigh 6.6 tons and 2.3 tons, respectively. It was designed by Salyut Moscow and first provided to China on four 956E ships in 2000. China imported 10 sets of the Fregate 3-D radar, with two placed on 052B DDGs in 2002 and two placed on 051C DDGs in 2006. The first reverse-engineered Chinese copy appeared on the 054A frigate in 2006.
Mineral ME Bandstand tracking radars provide missile control and over-the-horizon radar acquisition and target designation of surface ships. They can track up to 200 contacts and coordinate with up to nine other ships. The ME-1 active radar operates in I band with a 250-kilometer (155-mile) range; the ME-2 passive radar operates in D-G and I bands with a 450-kilometer (280-mile) range; and the ME-3 data exchange and orientation radar operates in I band with a 30-kilometer (20-mile) range. Designed by Typhoon Instrument Making Plant JSC Kaluga, the first of four were provided to China on a 956E in 2000. Imported Mineral radars appeared on two 052B DDGs in 2002 and on two 052C and two 051C DDGs in 2006. The Chinese reverse-engineered version appeared on the 054A in 2006.


The vertical launch system (VLS) forward of the bridge is similar to the U.S. MK 41 VLS.
The Russian MR90 missile guidance tracker-illuminator for the SAN-7 Rif-M Shtil SAM was designed by the Altair Marine Radio-Electronics Research Institute JSC. China imported eight S-band MR90s from Russia for four 956E DDGs in 2000. Two MR90 radars were tested for several years on the Chinese experimental ship 891. The first installation of a Chinese copy of the MR90 supported the HQ-16 vertical launch system (VLS) on the 054A in 2000.

This touches on what may be another piece of reverse engineering. The four rectangular VLS modules of the HQ-16 on the 054A appear identical to the U.S. Navy MK 41 VLS, but the United States has not commented on the obvious similarity. The MK 41 has been exported for many years to numerous nations, and a copy could have been expected sooner—such as on the 052C Luyangs. In fact, this rectangular-hatch VLS has been evaluated, along with an MR90 tracking radar, on the 6,000-ton weapon experimental Wuhu-B hull 891 for more than a year. Some experts assumed that this MR90 was a Soviet import, but it probably is the Chinese copy undergoing testing prior to installation on the 054A. Although the type of VLS SAM has not been identified, it would probably be the SAN-7, which is associated with the MR90 illuminator.

The 054A frigate has the Type 730 close-in weapon system (CIWS), based on the Netherlands Goalkeeper, which uses the U.S. GE GAU Phalanx gun. The Type 730 was on the 052B and 052C in 2002 and 2003, and it was on the 051C prior to the 054A frigate in 2006. Type 730 radars are very similar to the Signaal I-band search radar and dual I- and K-band track radar.

These recent stunning reverse-engineering successes do cause complications. One result is that combat system sensors are not matched on the hull and machinery generators, notably for MTU and SEMT diesels. Shaanxi Diesel Plant, also called Factory 408, has been licensed to serially produce French SEMT Pielstick and German MTU series diesels since 1974. In 1989, a second factory, Shanghai Hudong Heavy Machinery Company, was authorized to produce PA6STC diesels. Four of these diesels are on each 054/054A frigate.

SEMT Pielstick PC2-5 series diesels have 6-, 12- and 16-valve models, and MTU 956 diesels have 12-, 16- and 20-valve models (TB82, -32 and -92). The 052A has MTU 12-valve 1163 TB83 diesels, and the 052B has MTU 20-valve 956 TB92 diesels. Chinese factories produced them, and difficulties have been reported with them.

After all of these years, China still imports some SEMT and MTU diesel components from France and Germany. During 2006 and 2007, China imported 15 to 20 sets of German MTU 16-valve and 8-valve 396 SE84 diesels for new submarines such as the modern Yuan diesel boats. The same situation exists with China importing parts for 24 model 16 PA6STC diesels, which were used on the newest 054/054A frigates. Apparently China has not yet successfully produced these submarine or surface ship diesels without imported components.

Other notable Chinese PLAN reverse engineerings of foreign weapon systems include the Crotale/HQ-7/Castor C radar. Two sets of Crotale missile launchers were imported from France in the 1980s. Crotale missile launchers and associated Thomson CSF DRBC 32F Castor C fire control radars were installed on the Luhu DDG 112 in 1991. An upgraded Luda, hull 109 added a topside 8-round reload box aft of the launcher. The six Jiangwei II frigates launched from 1991 to 2000 had HQ-7 by China, with no reload storage. In 2002 the Crotale was replaced with indigenous HQ-7A on DDG 112. The 1993 Luhu DDG 113 and 1997 Luhai DDG 167 HQ-7 had reload rounds in below-deck hatches, which was not even available in French Crotale systems.
Two SS-12 variable depth or dipping sonars were imported from France in 1974. Three SS-12s were installed on Z-9 shipboard helicopters, and in 1987 Haiju craft hulls 688 and 697 replaced aft 57-millimeter guns with the SS-12. China procured one French Thomson CSF TAVITAC CDS computer, which was installed on the Luda I destroyer DD 105 upgrade in 1987. The first Chinese copy of TAVITAC was installed on Luhu DDGs 112 and 113 as the ZJK4 in 1991 and 1993.

China imported 40 A244 torpedoes from Italy around 1980. An improved A244/S was produced in 1984. Reportedly, the A244/S is produced under Italian license as the Yu-7 antisubmarine warfare (ASW) torpedo. Some reports of U.S. Navy MK 44 torpedoes being produced by China could be mistaken because both the MK 44 and the A244 have a similar shroud around the propeller. Some references state that Yu-7 PLAN ASW torpedoes are copies of the U.S. Navy MK 46 Mod 2, four of which were sent to China in 1986 for co-production. Because the sale was below the $14 million Arms Export Control Act threshold, Congress did not review the deal. Negotiations between the United States and China broke down, and Chinese attempts to change the hardware to metric measurements reportedly stopped in 1988.

India has been the recipient of many Soviet/Russian naval ships, aircraft and systems since 1965 (SIGNAL Magazine, December 1993, page 41), but these have come at a lower level, especially since 2000. India has one Russian aircraft carrier hull undergoing costly renovation for more than 10 years. India received a Russian Charlie-class nuclear attack submarine (SSN) in 1988, but India returned it in 1991 because of high radiation levels that were dangerous to the crew. Russia has exported modern warships with full suites of combat systems to India, including Mod Kashin destroyers (1986), the Krivak III (2000) and eight Foxtrot diesel submarines.

Prior to exporting two Sovremmennyis to China in 2001, Russia had limited its exported ships to auxiliaries and 1950s-vintage frigates, patrol vessels and Whiskey- and Quebec-class diesel submarines. The only destroyers Russia provided China were four World War II-vintage Gordyi-class ships in 1948. But India has had Russian CIWS 630 Gatling guns since 1986.

The trend of India becoming Russia’s favored high-technology export market is noted by recent negotiations for Russia to export two Akula II SSNs to India. These advanced nuclear submarines never have been available to China. India has been procuring and gaining production licenses from Russia and several Western nations for decades, and it never has copied any systems illegally. India’s Bharat Electronics Limited (BEL) and the country’s excellent Mazagon and Garden Reach shipyards have been successful in development and production of warships and systems. This contrasts with China’s record of illegally reverse engineering and producing systems without license from many nations.

Neither India nor China has built an aircraft carrier, but China has had more success at designing SSNs than India’s trouble-prone Advanced Technology Vehicle SSN attempt for more than 10 years. China’s recent gaining of a naval base in Myanmar, which is in India’s traditional sphere, points to the likelihood that future Chinese oil sea lanes to the Middle East will go through the Indian navy waters routinely.

The Soviet/Russian exporting of modern offensive systems to nations other than China has been obvious over several decades. One reason is that China has presented a possible threat to Russia with common border disputes and competition for Far Eastern power status. These circumstances do not apply to other customers.

Another reason could be that other customers will continue to rely on Russia for new systems. They will not copy illegally and refuse to buy more systems; nor will they compete with Russia in export sales to other nations. If this is a Russian concern, then the Sovremennyi exports resulting in the five copied systems on 054A frigates five years later justify Russian fears.



James C. Bussert is employed at the Naval Surface Warfare Center, Dahlgren, Virginia, where he works on surface ship antisubmarine fire control systems.






Those Russian engineers are job seeking immigrants hired by Chinese government. It's a shame that Russia can not keep those skilled workers and it's obsurd that you claim credit for the Russian tech. One should thank China for offering jobs to them in doing what they have been educated for.
Where is your proof that they were immagrants? My grandpa was KGB, it is not difficult to recruit forign engineers, esspecialy if they are retired.

What has Israel got to do with Russian flag?
What on earth are you talking about, who said anything about Israel and the Russian flag?




You should check your text book or ask your professor to learn how canards would interfere with stealthness.
Thats what the Chinese should do...

refer to post #33 or do a quick search. Canards omit large radar returns.


No wonder why Russia is already bit backward when it comes to the aerodynamic design of the next generation fighter.


I almost spit my coffee on my commputer when i read this *****ic statment. Most people around the world even the Americans regard Russian aerodynamics as world class, and how do you know anything about our 5 generation aerodynamic design? I got news for you...the public doesn't know anything about the design, and neigher do you.




You should pray for the oil price on a daily basis, because that is the only solid support for your economy.
You should pray that manual labor in China doesn't get replaced by robotic systems, but eventually it will, and when it does, your economy will take i hit.

What areas? The day China will stop purchasing Russian technology is the day i will beleive you.

Type 69, type 56....this will take all day but Chineses engines, Chinese radars, Chinese everything is copied from Russia. There is a reason Russia refused to sell the SU-33 or more SU-30MK-2's to China.

..............
Refused to sell? Your bosses wanted China to buy a large number of Su-33 together with Su-35. Su-30MKK2? It's obsolete stuff that China don't need to buy any more. China rejected your upgrade kits for Su-27sk and stopped buying Su-30MKK2, MKK3, ....

Chinese copied AESA radars from you? Your own AESAs are only test ready until recently.

Even Americans know China pirates Russian technology...
......

China did reverse-engineer both Russian and American military products. That is why I ask you to point fingers at the right stuff. Instead, you scratched all the nonsense accusations. I bet that you did not know a tiny bit of the true stories as to what exactly were licenesed to Chinese or copied by Chinese.


Where is your proof that they were immagrants? My grandpa was KGB, it is not difficult to recruit forign engineers, esspecialy if they are retired.
The Russian workers have work permits and live in China. How are they different from immigrants?

Retired? You might just be a kid and you don't know nothing about the mess in the 1990s. At that time there even wasn't enough food in Russia. I could not even spend 100 dollars in empty shops when I was in a two visit to St Petersberg.

You should be glad that you can still hold coffee cup in your hand. The PAKFA delay is not based on political reasons. You see what I mean? When PAKFA comes to light it would either look like a Sukhoi or a F-22. It will show you that the Russian innovation has reached a bottleneck or an end.

Kid's language! Enjoy your life while the oil is still running out and also remember that the life expectancy for a Russian man is only 60 years.

China didn't stop buying anything infact, the Chinese planed on buying the SU-33 in late 2006 and Chinese Premier Hu’s visted Russia March 2007 in hopes of purchasing more SU-30MK2's, and Russian told China to piss off.

Chinese copied AESA radars from you? Your own AESAs are only test ready until recently.
I can tell your English is bad, that's not what i said. I said Russia already has several models of AESA, how many models does China have officially?

I listed several examples such as the type 69, and 56, then i gave an intire artical discribing how the Chinese copied the 054A.

You want more specifics, fine.

In February, Russian defense official Mikhail Pogosyan said the Chinese defense manufacturers had done so in breach of intellectual property agreements, DefenseNews reported.

The Chinese had apparently earned the license to build the Su-27SK but then developed their own version outfitting it with their own avionics and system against the provisions, the source added.

The Chinese simply copied or modified Russian avionics.

China military 'copy' machine irks Russia






The Russian workers have work permits and live in China. How are they different from immigrants?
What Russian workers????????? Where is the proof that those Russian engineers lived in China? They stayed in China to assist in the development of the J-10, but by no means where they "living" in China because they wanted to.

Retired? You might just be a kid and you don't know nothing about the mess in the 1990s. At that time there even wasn't enough food in Russia. I could not even spend 100 dollars in empty shops when I was in a two visit to St Petersberg.
My god, you need to take some English classes. When did i say i was retired? I said my grandpa is a retired KGB agent, it is not difficult to recruit forign engineers, hense the Russian engineers working on the J-10 were likley recruited by Chinese intellegence.



Read your own post. What's Israel got to do with a Russian? .

What the hell are you talking about?

The only thing i said about Israel is they assisted China with the J-10. Here is what i said word for word....

Even the J-10 used Russian and Israeli engineers, not to metion the Chinese had access to the Lavi.

Any ways i have no idea what you are trying to say, so what does Israel have to do with Russia? I don't know, you brought it up not me.




You need to ask experts instead of presenting internet crap as evidence.
Crap evidence? First off, one of the sources i posted was from an expert. Secondly, i gave a link stating that the Russians removed the canards from the SU-35 in order to reduce the RCS. Thirdly, i gave another link stating that canards do indeed give off larger rcs compared to none canard set-ups.

I provided you links. You don't want to beleive them? Fine, thats your problem, but that just shows you can't except the truth, in other words your in denial. Anyways I don't need an expert to tell me that the Great Wall of China is real, i can do the reasearch for myself.



You should be glad that you can still hold coffee cup in your hand. The PAKFA delay is not based on political reasons. You see what I mean? When PAKFA comes to light it would either look like a Sukhoi or a F-22. It will show you that the Russian innovation has reached a bottleneck or an end.
Keep you personal feeling out of this...

Again you don't know how the Pak Fa will look.

When the Mig-15, Mig-21, Mig-25 ect all came out there was nothing else like them. Thats not to say Russia didn't mimic some US aircraft like the B-1, but we had innovation, and we will continue to have inovation. When did China have innovation? It's not very innovative to buy licenced copies then give them a different name, just like it's not innovative to employ Russian and Israeli engineers to copy the Lavi, then say it's fully indigenous.




Kid's language! Enjoy your life while the oil is still running out and also remember that the life expectancy for a Russian man is only 60 years.
Kids language? you insulted the Russian econmoy by saying Russia will be poor when gas supplies run, but when i said manual labor will be replaced by machines, it kids language? You sir, have a double standard, and yes, machines are replacing people.

And sorry, buddy i don't drink, nor do i smoke. I'm healthy, TALL! and i stay in shape. I really hate when people like yourself have to insult, and steryotype a people or country. Did i mention i was tall? Some countries, i'm not going to name names, have really short people.

Apparently it is not enough for the J11/J10 when the WS-10A is not achieving desired thrust in required timeframes. WS-10A still uses ejector nozzles which are obsolete for high-bypass turbofans. Iris nozzles are required to adjust the thrust for variable altitude, speed, and atmospheric conditions in the high performance regime. Why Chinese would bother using ejector nozzles on an engine that requires Iris nozzles boggles the mind. They must have seen the difficulties this would present but they continued anyway. Now they have two squadrons of J-11s with these worthless engines and according to what you are saying, are making more. They might as well have upscaled the R-11 of the MiG-21 and could get the same performace... or maybe that is what they did?
