J-20 5th Gen Fighter Thread IV (Closed to posting)

An old photo only made available very recently. The resolution is decent. I wanted to post this because it has fantastically clear details.

The build quality is simply superb.

And it does so at a considerable expense of your endurance. While the "raw thrust in certain situations" argument is of course to the point, saving fuel for those situations as much as possible is a prudent idea. Realisticly, I would say modern high-end fighters should have engines powerfull enough to (among other things) get through transsonic acceleration with dry thrust in a reasonable amount of time.

Well Scratch, I was probably a little to casual about that post, in reality the USAF wouldn't buy aircraft with afterburner, if they had an abundance of dry thrust,as its heavy, maintenance intensive, and burns fuel at a prodigious rate. That why I stated the J-20 and PAK-FA needed enough dry thrust to supercruise, to avoid having to use afterburner to intercept and engage OpFor, in reality, they are operating the best engines they each have available. As I'm sure you are well aware, afterburner/reheat is as the name implies an additional combustion chamber added to the engine to develop additional thrust, that additional thrust is a life saver every day. In a heavy, fuel and weapons laden fighter aircraft, it is much safer to accelerate rapidly to flying speed, less ground run, less time on the runway, better initial climb rate, and pilots most always get out of burner once they are at best rate speed, maintaining maximum dry thrust if needed to clear obstacles, the exception is when a max rate climb in burner, gets you to your most efficient cruise altitude, and you are able to throttle back sooner.

That's why all modern fighter aircraft depend on in-flight refueling, in order to top off at altitude to extend your range. So rather than implying it was just to make noise and have fun, I should have stated that since the inception of the jet age, afterburners have been magnificent performance enhancers when available, and well worth the additional weight, maintenance, and fuel burn to provide an extra margin of performance, and safety?

Very Kool Deino, and thank you brother for your very fine work on the SDF. Now to show my own ignorance, I just noticed two kool air inlets on the lower leading edge of each wing tip, maybe 18" X 3" , I know you need ambient air for venting fuel, cooling, etc??? any thoughts on these gentlemen, and does any other jet fighter have these???

Funky motto for AVIC: "Tell the World (That we are real!)....Tell the future (We have arrived)" No I'm not poking fun at AVIC, just wondering if that's their motto or someone else.

Isn't that just indicator light, similar to the ones on the tail fin?

I don't think so, but you could be right, if it were a light, I would think it would be oriented longitudinally rather that at an angle, looks like a vent to me???? but it is so big??? hummh???

I would agree with noname that it's just another luminescent light for orientation. Just like the light on the vert stab it is alignt with the leading edge to indicate the orientation of the plane at night. I guess also a help in formation also, as in close fingertip you normally look down the lead aircraft's wingline to position yourself correctly.

In my mind it looks exactly like the thing on the lower nose side just above the number, which, as seen in post #2830, in another such light.

That's why I asked you young lads with the sharp eyeballs!
