33,000 lb engines are not impressive for a 2027 jet. WS-10G which currently powers J-20 prototypes are around 32,000 lb.

The yellow one is called J-15, Chinese Version SU-33, which is as long as J-20. So you guys can stop the debate now.

Can I ask, if the turning performance is depend on nothing but the L/W, what are the strake wing and canard for?

J-20’s canards are much bigger than J-15 / Su-33’s canards, plus they are squary rather than triangulary :rolleyes:

F-22 blueprints were all destroyed at the request of the Department of Defense. At this point, it would be easier and less costly to develop a twin engined version of the F-35.

just commenting on one thing here and I’m not saying anyone is really guilty of it, but I’ve seen the claim that SAC managed to design this aircraft based on the information they hacked from Lockheed everywhere on the internet.

If anyone has seriously followed SAC’s struggles in developing J-11B, J-15 and J-16, they would have less confidence in SAC’s copying abilities. China has had Su-27s for 20 years and all of the technical documentations and production line for Su-27s for 16 years and they’ve only barely managed to deliver J-11B into service for about 2 years. And based on J-11B performance in the past year, it’s hard for me to call this project a success. And that’s when they’ve got all the blue prints, production tooling, Russian produced parts. And somehow, some people believe SAC can just somehow magically reproduce an aircraft just relying on data they hacked from Lockheed Martin despite have totally different engines, aircraft material, design objectives and electronics.

Also, even though CAC and SAC are competitors within AVIC-1, they are still cooperative in the sense that they do share designs. For example, SAC is said to have been fairly involved with the J-20 project.

Politics run deeper than what is reported in the media. The Democratic party shares similar ideologies with China’s Communist party. I wouldn’t be surprise if there’s quite a bit of under the table deals between China and the US.

Su-27 has a relaxed stability design like F-16 does, which required the use of FBW. This gives it better agility than F-15. With LERX, Su-27 is like a twin-engined F-16, having better aerodynamics than F-15.

Simply since it is a common term used here so often. Regarding the usual stupid Lavi-J-10 discussion I think at least by know no-one would call it a “copy” anymore, but since – at least officially – a licence was only granted for the Su-27SK to be build as the J-11, these latest J-15 and J-16 are more or less “copys” … maybe the term “reverse enginered” types would be better.

early designs of J-10 were identical to Lavi. only in the later stages was the design altered to fit an AL-31 engine

Comparing the J-31 to the J-20 from the front, it appears J-31’s wingspan is quite a bit longer than J-20’s 12.88 meters, and therefore would be used primarily in the air to air role whereas J-20 would primarily be used in the strike role.

Looks like a twin-engined F-35 to me, with a much wider wingspan. Could be a J-10 replacement.
