J-20... The New Generation Fighter

Re: New Generation Fighter

i think it could be air brakes

Too small for air brake. Besides, she can turn the vertical tail planes against each other for braking.

It didnt take long. J-20 and chinese aircraft industry in general are already being bad-mouthed in russia.

Nothing worth to make out. Your standard Russian dribble on the PLA.

Some one is being sour after realising that the Su-35 deal probably won't fall through...

Re: New Generation Fighter

China has had to have made some breakthrough on materials. J-20 being that large and continued belief that any domestic engine is going to be weaker than of Russian and Western design, you aren't going to design an aircraft that big with 5th gen requirements and not have a materials breakthrough to the least. Maybe that's why they painted it. The specualtion of why it's already painted is because people wanted to see the materials.

That's for the brake chute. There is a picture posted earlier which shows the J20 deploying its brake chute from there.

Re: New Generation Fighter

I wonder if the upward cant of the canard is a way to control the release of a creeping wave from the trailing edge.

I don't think so. I think it's made for aerodynamic purposes. If the canards were completely in line with the main wings, then they might as well be LERX's. The upward cant should let it function much like the other canards we've seen, which have been invariably placed above the main wings. Only the shape, not the orientation, of the canards can affect the creeping wave effect.

I've seen it. But my remark was made while I was belatedly looking through the posts. In post 1804, and earlier, there's a nice photo of the tail planes turned independently. Of course you can do that to that extend only at low air speed.

Re: New Generation Fighter

I wouldn't say that the project came out of no where. Plans for China's J-XX project started in the early 90s. However I would say that the speed at which the prototype came out is truly astonishing.

What if China never revealed or mass produced J-10 post-2006 but instead directly unveiled J-20 in 2010? Then China would go straight from J-7 to J-20!

Then China can claim it came from aliens and really shock the world.

Short take-off? Probably not.... kind of heavy.... unless you have 2D TVC.
The real limit is not TVC, but the maximum attitude the aircraft can achieve without the rear hitting the runway. This is limited by the length of the main undercarriage.
