Chinese J-20 Stealth Fighter

Chinese J-20 Stealth Fighter has entered its test-flight completion stage following the launch of two prototypes in quick succession last month.

The latest prototype, the eighth in the series, "proves" that the results of test flights are "satisfactory". These tests which include aerodynamic performance, stealth performance and airborne equipment have met or are close to the index requirements, China Military Online, the official publication of the Chinese Defence Ministry reported today.

The latest China-made fourth-generation J-20 stealth fighter with fuselage number 2017 has successfully completed its first flight on November 24, 2015, only two months after the launch of the prototype with fuselage number 2016. This is the eighth China-made J-20 fighter aircraft and the sixth J-20 prototype used for test flight.

The canopy of the J-20 fighter with fuselage number 2017 comes with metal-film coating which can further improve the fighter’s stealth performance, the report said.

Quoting Fu Qianshao, deputy editor of the PLA Air force's Aviation Magazine the report said that the eight prototype can be classified into three categories; the black color J-20 fighters with fuselage numbers 2001 and 2002 are technical verification models, which are similar to the U.S. YF-22 prototype models; the J-20 fighters with fuselage numbers 2011 and 2012, which have different coatings and appearances from the previous ones, are the engineering prototype models; the ones with fuselage numbers 2013, 2015, 2016 and 2017 are prototype models, which are close to the stereotyped (production) models.

“It is possible that the China-made J-20 fighters will soon be deployed to PLA troops,” Fu claimed.

Chinese J-20 Stealth Fighter Nearing Test-flight Completion

And now we finally have proof that the #2016 black nozzles are not simply a coating of black paint. There would be no need to paint it black and now silver. The nozzles are black because the material composition is different from the standard AL-31FN. But do we have proof that Russia is providing a special purpose built 'black AL-31FN' in small numbers to China? Do we have proof Russia is involved in the J-20 program at all? The mystery deepens.

The silver nozzle and black nozzle are just different variants of the WS-15.

The black nozzle of J-20 doesn't have any blue shade, so it is different from that of the AL-31F.

How can you be 100% it's not WS-15. Have you see a real WS-15 works before? Is your conclusion based on observation but not facts? Lol. I hope you take back ur 100% claim.

In an another way, could you proof that it is WS-15 ?

If I'm not wrong, WS-15 just finished 100h ground test in 2014. Have a look on all other programs in the world, how many they needed on ground tests before being mounted on board a flying testbed, and how many in a flying testbed before mounting on the target aircraft ?

Chinese move fast, we can only approve this, but it doesn't mean that we can ignore physical rules.

Even the painted nozzles look different.

Here are #2015 nozzles. Notice the dark lines between the silver indicating the gap between the nozzle petals.

#2016 nozzles are a solid silver.

Where have we seen this before? Right here.

No, ... I would bet my membership here at this forum on this issue. It can't be a WS-15 ... this engines was not even tested on a Il-76 and You think - IMO pure wishful thinking - that it even powers a J-20 right now. Honestly, but that is IMO simply naïve.

Again I will expand my bet. It is a specialised version of the AL-31FN ... a WS-10 simply can't be ... but I already explained You so often the differences.

China military let u see what they want u to see. While things they do not want you to see they have the ways to hide it. They have many secret bases in Inner Mongolia where all many things are out of sight of public. China has even ways to hide a real ASBM on sea, not to mention talking about testing of engine.

China is such a big country. They have plenty places to do varies test in secret.

Why would China need to hide the development of aircraft engine?

Not like China only nation with the secret to develop and produce jet engine, China jet engine still lag behind the west or Russia.

How would they wouldnt want to hide the test. They want you to believe what you want to believe. Letting you think China aviation propulsion is weak can be a surprise for enemy.

No info of real test of ASBM ever leak, what we we have seen are just few possible tested site but we do know real ASBM has tested before on real sea. They like to keep you in suspend and keep you guessing China real military depth. It will always be part of the deception doctrine borrow heavily from Art of War.
