Sukhoi PAK FA

[sorcerer]

For only USD 3.7bn India will get all the sophisticated technology of a 5th-gen Stealth Fighter
After repeated delays, India and Russia have agreed to a detailed work-sharing agreement for the joint production of design and production of a new fighter jet under the so-called joint Sukhoi/HAL Fifth Generation Fighter Aircraft (FGFA) project, known in India as the Perspective Multi-role Fighter (PMF), according to Indian media reports.


“From a preliminary document that was barely two dozen pages, we have agreed on a 650 page detailed plan that specifies exactly what all will be shared,” an unidentified Indian defense official told The Economic Times. A final contract is expected to be signed in early 2017.

The talks between Indian and Russian defense officials were allegedly accelerated ahead of an Indian-Russian summit to be held in Goa on October 15. As I reported in January, Russian President Vladimir Putin and Indian Prime Minister Narendra Modi failed to reach an agreement during a bilateral meeting in Moscow in December 2015.


The FGFA/PMF project has been hampered by repeated delays since the start of the project in 2007 and the signing of a preliminary $295 million design contract in 2010. In 2015, Indian Defense Minister Manohar Parrikar decided to make one last push toward reaching an agreement with Russia. I explained:

Delays were caused by New Delhi and Moscow disagreeing over many fundamental aspects of the joint development project including work and cost share, aircraft technology, as well as the number of aircraft to be ordered. After evaluating the first PAK FA T-50 prototype (the Russian prototype of the PMF), the Indian Air Force (IAF) wanted more than 40 changes addressing, among other things, perceived weaknesses in the plane’s engine, stealth, and weapon-carrying capabilities.

Russia announced in late 2015 that it would only induct a squadron (18-24 aircraft) of PAK FA fighter aircraft, and procure additional Sukhoi Su-35 aircraft instead. The original deal involved Russia procuring 250 and India 144 aircraft at a cost of around $30 billion by 2022. As a result, India threatened to abandon the project in its entirety. Russia in turn made a number of concessions including an offer to cut down its financial contribution from $6 to $ 3.7 billion for three PAK FA T-50 prototypes and substantial technology transfers.

Despite the agreeing on a work-share plan, problems with the FGFA/PMF project nevertheless will remain (See: “Russia Tests Components of New 6th Generation Fighter Jet on 5th Generation War Plane”):

Russia’s defense industry is still facing technical (as well as financial) hurdles including designing a new engine for the aircraft, given that PAK FA prototypes are currently using engines also installed on Sukhoi Su-35S 4++ generation multi-role fighter jets, calling into question whether the PAK FA can genuinely be classified as an 5th generation aircraft

As part of the effort to salvage the defense deal, Moscow has also agreed to let Indian test pilots fly the PAK FA T-50 prototype currently undergoing flight trials in Russia. Hundreds of flight tests have taken place over the last months and the Russian Air Force expects the first aircraft to be inducted into its ranks in 2017. Nevertheless, many senior officers in the IAF remain skeptical about the aircraft’s affordability and capabilities.

Do DFI`ans really think Russia would really share senstive technology , they would some how fool HAL again

So far thats in the media.

Hasnt Russia shared sensitive technology before. Is current (Right now at this hour) Indian security relying on RUSSIAN SENSITIVE TECHNOLOGY which is already shared.

It would be foolish to think too early that Russia would fool HAL with a strong Indian Government who means business and who has many options by its side.

I do not know if we should rejoice or bawl our eyes out.

Seems to me like the Russians have not been able to complete the design.

Russia announced in late 2015 that it would only induct a squadron (18-24 aircraft) of PAK FA fighter aircraft, and procure additional Sukhoi Su-35 aircraft instead. The original deal involved Russia procuring 250 and India 144 aircraft at a cost of around $30 billion by 2022. As a result, India threatened to abandon the project in its entirety.

many senior officers in the IAF remain skeptical about the aircraft’s affordability and capabilities.

If they plan to induct only one squadron, the development is not complete. Period. The plane looks like its at the stage where the T-10 was in late 1970s-early 1980s. It took a while to develop into the Su-27 and even more time to develop into the Su-30 and then the Su-30MKI.
What they want by 2022 is a Su-30MKI level development (which is now impossible) What they have now is a T-50 akin to the T-10. They must have realised their timeline was too ambitious and wanted to induct a squadron now, and then keep developing the aircraft to a Su-30 level after which they plan to start mass inductions. They knew the Indians are not going to wait that long so they are offering a "concession" and technology transfer.

Well, the kind of machine they are trying to build is no mean feat and the project was too ambitious from the get go. I am somehow happy that they are going slow and steady and have planned to scale-back the size of initial procurement (down to a squadron from the initial 250). Look at how the Americans went for an ambitious program and refused to scale-back. The result was the F-35: the most expensive weapons program in the history of mankind and its critics are not impressed with the product.

Sometimes its better to be cautious than penitent later on.

Thats the catch of it all to keep it relevant.

 

[smestarz]

India is at the cross roads of both time and technology, India was never in such a good position of having so many options. For example,. We would be getting Russian planes and for which we closed down our aerospace industry because of cheaper russian imports, The American products were what we coveted but they were for Pakistan only. France took their pound of flesh when we purchased their weapons (they do so even now)
India has a strong economy at its weapon industry is waiting to grow. India being 7th largest country in the world with strong economy and adolescent defence industry, we are the ones who the world wants to work with. The Americans have strong armed forces and excellent defence industry but then all the companies are not able to get big share of the pie. Russians have excellent defence industry but lack the strong economy to fulfill their aims thus India becomes a natural choice for them to have a co-operation with and by which they automatically reduce the cost of development and also cost of production since more numbers will be ordered. Why you think F-35 can be so cheap? its only because of big nos, and for rht esame reason Rafale is expensive. China is a capable country, they have their own industry which as of now depends on copying others technology shamelessly. They have that track record. Russia (and the world) has seen that India is very ethical in its defence dealings which makes it very attractive for countries to seek partnership with India.

Thus if Russians are giving all tech to india for 5th Gen plane, its not that they are not keeping it away, We have contributed partly for the development of these technologies. thus Russians are the brains, but also we are the money power behind it. Which country in the world has big requirement as India and also no border dispute with Russians? Brazil maybe ???

For only USD 3.7bn India will get all the sophisticated technology of a 5th-gen Stealth Fighter

The actual PAKFA is supposed to fly with "Item 30" engine which is under development and then it will truly be the plane that PAKFA was designed for, but would the Russians wait (like Indians did for Tejas to be exactly how IAF wanted?) the Russians are willing to use it with "item 117" engine. Thus the Russian pilots get the taste of using PAKFA in operation. And by the time Item 30 is ready, they will go for the actual PAKFA . The older planes with Item 117 engines as per me would then be replaced with Item 30 engines.

The Russians want to get PAKFA operational so that it can then get prospective orders from countries like Iran and India as well and maybe countries like Vietnam .. Not many countries will put money on a plane which is not operational but a plane that is operational, countries will want to buy those.

The Russians (like the Indians) went for lot of technologies being developed to come into the new plane and like Ijndia they are also faltering on the engine, but unlike India, the Russians have an engine which they are using to sort of produce PAKFA - and they also have vast experience and facilities to successfully develop the engine they plan to use. unfortunately for India it was our first venture to develop our own engine without any prior experience.

I do not know if we should rejoice or bawl our eyes out.

Apparently, according to Russian news daily Izvestia the Izdeliye 30 engine equipped equipped PAK FA can be expected at 2025-2027,that's ~8-10 years from now

Also it seems PAK FA in it's current state doesn't meet the RuAF expectations for T/W ratio and fuel efficiency

http://nationalinterest.org/blog/th...tealth-fighter-might-have-fatal-flaw-or-16628

As has been said before , this is taking too long and India doesn't want to wait that much,this ToT has to be quite something if the Russians want to keep us hooked

Test are planned for next year, as for present engine it gives more then sufficient performance but newer engine will have better IR reduction Mechanism along with more power and fuel efficiency

 

[Bahamut]

@gadeshi What r IR reduction mechanism used in PAK FA?

 

[Raj Malhotra]

Even if Russia provides technology, HAL is incapable of absorbing the said technology. Production contract for PAKFA should be given to conglomerate of Indian companies like TATAs, L&T etc.

What made you think that TATA's and L&T's would be able to absorb the said techs? Atleast HAL had the background of creating and assembling vital aeronautical part and assembly along with fairly decent R&D.

 

[Gessler]

What Russia will share as part of ToT will be enough to faciliate local production of the FGFA. In short, what will be shared will be production-engineering knowledge/procedures for the majority of components in the plane. Other than that - we might get contracts for designing/producing some components unique to our version here, from the ground-up. Like comms equipment etc.

Nothing more, nothing less. If you're all thinking Russia will open up all it's IPRs for Indian companies to plunder, you're all mistaken. I've said this before.

On topic, it seems the cost for developing the FGFA prototypes and the initial production lines is reducing - that's a good thing. From $6 billion at one point to $4 billion a few months ago and now $3.7 billion. The more money we save here, the more money will be available for purchasing more FGFAs in the long term, or buying Phase-I PAK-FAs in the short-term.

 

[Scarface]

If that was the case then there would be no reason to create the Izdeliye 30.5th gen aircraft have more power requirements than 4th gen engines can provide.

RuAF doesn't seem to find the engines sufficient considering ther dissatisfaction regarding the T/W ratio and Fuel efficiency

RuAF doesn't seem to find the engines sufficient considering ther dissatisfaction regarding the T/W ratio and Fuel efficiency

T/W is 1.02 at max takeofff weight and 1.19 for typical take off load and range is 3500 km subsonic and 1500 super sonic .It is ok but with newer engine it is 1.16 for max takeoff weight and 1.36 for typical take off load

Pre-production and initial production batches of the T-50 will use interim engines, a pair of NPO Saturn izdeliye 117, or AL-41F1.[87] Closely related to the Saturn 117S engine used by the Su-35S, the 117 engine is a highly improved and uprated variant of the AL-31 that powers the Su-27 family of aircraft. The 117 engine produces 93.1 kN (21,000 lbf) of dry thrust, 147.1 kN (33,067 lbf) of thrust in afterburner, and has a thrust to weight ratio of 10.5:1.[88] The engines have full authority digital engine control (FADEC) and are integrated into the flight control system to facilitate maneuverability and handling.[78]

The two 117 engines incorporate thrust vectoring (TVC) nozzles whose rotational axes are each canted at an angle, similar to the nozzle arrangement of the Su-35S. This configuration allows the aircraft to produce thrust vectoring moments about all three rotational axes, pitch, yaw and roll. Thrust vectoring nozzles themselves operate in only one plane; the canting allows the aircraft to produce both roll and yaw by vectoring each engine nozzle differently. The engine inlet incorporates variable intake ramps for increased supersonic efficiency and retractable mesh screens to prevent foreign object debris being ingested by the engines.[78] The 117 engine is to also incorporate infrared and RCS reduction measures.[89][90] In 2014, the Indian Air Force openly expressed concerns over the reliability and performance of the 117 engines; during the 2011 Moscow Air Show, a T-50 suffered a compressor stall that forced the aircraft to abort takeoff.[91]

Production T-50 from 2020 onward will be equipped with a more powerful engine known as the izdeliye 30, a clean sheet design engine that will supersede the 117. NPO Saturn and MMPP Salyut are competing to supply this definitive second stage engine.[28] Compared to the 117, the new powerplant will have increased thrust and fuel efficiency, greater reliability, and lower costs.[88] The izdeliye 30 has fewer fan and compressor stages than the 117, thus reducing the number of parts compared to its predecessor. The engine is designed to produce approximately 107 kN (24,050 lbf) of dry thrust and up to 167 kN (37,500 lbf) in afterburner. Full scale development began in 2011 and the engine's compressor began bench testing in December 2014.[92] The first test engines are planned to be completed in 2016, and flight testing is projected to begin in 2017.[93][94] The new powerplant is designed to be a drop-in replacement for the 117 with minimal changes to the airframe.[95]

 

[gadeshi]

@gadeshi What r IR reduction mechanism used in PAK FA?

Just like on F-22 and F-35 - nothing except for nano-dispersal quartz balls in topcoat paint.
The other measures like cold air mix into the engine exaust and limitly flat nozzles are not effective against the modern IRST so they are not applied.
