J-21/J-31 Chinese 5th Generation Stealth Fighter

[GromHellscream]

I don't see any feasibility to turn JF17 into a stealthy one. it is just too small, which rules out bayed ammunition.

Follow the same way of what SAAB propose to do on Gripen, and achieve an Air-Deniable defence fighter.

at least we are not purchasing those junk fighters made by china.come on mate you guys can't even make a proper jet engine for your junk fighter-17 and you think that anyone would believe that you are making two parallel fifth generation fighters!you people can't even lie properly:taunt1:!

You can continue deny everything, be our guest.

So many stealth fighters in one go.sure not even americans and russians are capable of doing.
What will be the engines of these multiple fighters?

Might only be an export variant, calm down.
It is very unusual that for the official media to cover the maiden flight in such a quick manner:

and the designation is so NOT PLAAF style --- AMF, sounds like an IAF designation.

Russia's GDP is currently only a fourth of China's and China also has whole lot more engineers than Russia has. Thus outdoing Russia doesn't really say much about China these days. Even if we just restrict the scope of discussion to aviation industry alone, Russia sure has lots more tradition and experience, but China has more greenbacks, more personal and more political will, and last but not least a much more complete supply chain (russia's aviation industry got crippled up after the break-up because many parts suplliers either have shut down or are not available longer). Currently China has just as many if not more aviation projects going on than Russia has, both militarily and civilian.

The point here really is not about how advanced J20/J31 are or not, vice versa F22/F35/PAK-FA, it is about being a player in the 5th gen fighter business. China clearly is a player along with US and Russia, India on the other hand is a by-stander. Even if India does carry out the plan to 'co-develop' something with Russia, her role would still only be a cut above being just a pure by-stander.

^ Most of the Chinese cutting edge hardware is either a inferior clone of it's Russian equivalent or designed with considerable help of Ukrainian's/Russians.
Take a look at J-20, certainly looks inspired from Mig 1.44. Your current mainstay J-10A looks like a copy of Israeli Lavi. The Flanker clone J-11B inferior to it's original counterpart, there were reports J-10 beating J-11B in air to air combat. Most of your mainstay Anti Air and Anti Ballistic missiles are inferior clones of it's Russian counterparts or just licenced produced in China under a different name :
PLA Area Defence Missile Systems

There is general agreement in open sources that the HQ-9 uses Russian S-300PMU technology extensively, including the cold launch design for vertical ejection from launcher tubes on TELs, 5V55/48N6 rocket motor technology, and a range of other S-300PMU components, including an 8 x 8 four tube TEL modelled on the 5P85SU/DU series. Some sources claim the weapon uses a two stage arrangement akin to the S-300V, imagery shows these claims to be incorrect. Slant range performance figures also vary across sources, between 50 and 100 nautical miles. What data is available suggests a missile which is similar in capability to early variants of the MIM-104 Patriot and SA-10B 48N6E, including Track via Missile (TVM) guidance.

Chinese even copied the Russian TEL's

The HHQ-9 is the navalised variant of the HQ-9, launched from a VLS system, on the Type 052B/C Luhai II class DDG.

Very little has been disclosed to date on the HQ-16 SAM system. Most sources describe it to be a joint PLA-Russian evolution of the SA-11 Gadfly or SA-17 Grizzly medium range semi-active radar homing SAM. The PLA-N deployed the VLS 9K37/9M317M Yozh / SA-N-12 Grizzly on the Type 956EM Sovremmeniy class DDGs under the designation HHQ-16.

More recent imagery of a SAM mockup suggests the HQ-16 is a licenced derivative of the baseline 9M38 Gadfly missile using the long chord short span cruciform strake design, rather than the 9M317 series missile airframe. This is consistent with the Russian practice of licencing the PLA for the production of equipment variants no longer built for Russian use.

HQ-2 -- The Chinese built derivatives of the Soviet SA-2 Guideline were, until the arrival of the SA-10/20, the numerically most important SAM system in PLA service. Current official US estimates put the remaining inventory at more than 60 batteries, for a total of about 400 single rail launchers.

Russia 'helping' China with fighter jet technology
Sources suggest Mikoyan 1.44 stealth jet knowhow has been passed into the hands of Chinese arms designers

A source close to Russia's defence industry said the similarities suggested Mikoyan technology had been passed into the hands of Chinese arms designers.

"It looks like they got access "¦ to documents relating to the Mikoyan – the aircraft that the Ministry of Defence skipped over in its tender to create a stealth fighter," he said, speaking on condition of anonymity.

Chinese J-10 'benefited from the Lavi project'

Chinese J-10 'benefited from the Lavi project'

Russian aerospace engineers have confirmed to Jane's that China's Chengdu J-10 fighter aircraft benefited from significant, direct input from Israel's Lavi programme - including access to the Israel Aircraft Industries (IAI) Lavi aircraft itself.

In a number of interviews Jane's has talked at length with several engineers, designers and technical specialists - some of whom have been working with their Chinese counterparts for decades and have had first-hand experience on Chinese military projects. They have provided detailed accounts of the assistance given to various Chinese manufacturers and their military aircraft projects. This has included extensive design and performance modelling, wind-tunnel testing and advanced aerodynamic design input.

Senior Russian engineers who spoke to Jane's recalled their many visits to Chengdu, and elsewhere in China, some of which began in the 1980s. Jane's was told how Chengdu officials of the highest level stated how they had one of the IAI Lavi prototypes in their facilities. Describing his conversations with Chengdu concerning possession of a Lavi aircraft, one Jane's source commented: "I did not consider that to be a revelation ... doesn't everyone know that already?"

It is not possible to independently verify the Russian comments. The charge of Lavi technology transfer has been made before, but this time the claims come from individuals with sustained personal experience of the programme. Both Chinese and Israeli officials have long refuted any purported links between the J-10 and the Lavi.

The Z-19 is yet another Chinese helicopter based on the Eurocopter Dauphin (which has been built under license in China for two decades). The Z-19 is a 4.5 ton, two seat armed helicopter. It can carry a 23mm autocannon and up to a ton of munitions (missiles, usually). Cruising speed is 245 kilometers an hour and range is 700 kilometers. The Z-19 is basically an upgraded Z-9W.
--------------
China is also developing a larger (7 ton) and more complex Z-10 helicopter gunship. This project has been going on for 14 years and several prototypes have been built. Attempts to buy or steal helicopter gunship technology from Russia and South Africa failed.

from the pic it looks like J10 is being chased by J31.

There is no J10 in the pic, it is a J11BS, from this perspective, it might be the J11BS was leading the flight in a way.

I was playing around with our dear Indian Bhais , but sina is an official media, as long as internet media is concerned.

when you fly for the first time it does not lead, chase plane is their to keep an eye on new plane.

 

[J20!]

The J31's underside is a good deal smoother and thus stealthier than the lumpy bumpy F35:

 

[shiphone]

I'm afraid there is no J10 here ...it's a twin-seat J11BS

the Prototype is much smaller than the J11BS...so in a camera lens ,it looks like what you said.

Clearer frontal shot. In this one its trapezoidal vertical fins make J31 look like a baby Raptor:

Hard to tell without any identifiable background reference in the sky.
anyways, they flew together.
