J-20... The New Generation Fighter III

delft said:

Strength and height of the main landing gears show that this aircraft is not designed for use from aircraft carriers. When landing on a pitching deck the tail may hit the deck before the main landing gear is fully compressed unless the main legs are much longer than J-20's.
Besides China needed an answer to F-22, a fighter with a long range. You don't compromise fuel weight to provide a structure able to withstand deck landings in your first LO aircraft.
Also it is asking for trouble to design an aircraft for both land based and carrier based use. Think of TFX and JFS. Adapting an aircraft designed for one use later to another use, as in F-4 and Su-27 is something different.

I see. But that's to say that they still can navalize the current J-20, isn't it?

Even if they could, it would be a whole different plane than. Might as well design a whole new air frame for it, instead of fitting the naval requisite into a an air force frame (i.e. F-35).

30-degree per second instantaneous turn at low speed.

OK, I did my own count: 10 seconds (from the 9th to the 19th second). That would make it 36 degree per second. How does everyone else count it?

The J-20 did not begin the sharp turn immediately after banking. Ignoring the slow turn rate and counting only the higher turn rate, I counted about six seconds in the half turn.

Are the 2nd, 3rd, and 4th pictures PS'd? I love them!

And you take on that would be? ... For example, what might be the Gs it sustained during that half turn?

Technically the F-22 fulfills the interceptor role too. The question is whether the J-20 by design is strictly dedicated or specialized to that role, and my inclination to that answer is a probable no.

I absolutely agree with you, it is in fact our only true interceptor, a proud Lockheed tradition going back to the F-104, and why you forum jockeys object to calling your black bird an interceptor is rooted in one large fallacy, that it is somehow an insult by those who I suspect think that means it won't turn with a Raptor. The ability to have a large, fast, fuel effiecient, fighter aircraft to go out and take out the bad guys assets at long range is job one of the PLAAF, don't doubt me on this, and this bird is singularly equipped to do so. We know it will turn, and in fact I have complitmented many of you who have convinced me of its agility, but it is an INTERCEPTOR! Why do you think we station Raptors at Elmendorf Alaska?

I have never stated that it is limited to one role, just that defending your nation against an incoming aircraft or vessel does require a long range interceptor, and the J-bird is the very picture of form follows function there, we know it will turn, and I believe it has been designed knowing that it will likely encounter some very potent opposition!

This aircraft is a PLAAF flagship, as such it has been designed for the A2A role primarily, heavy naval equipment is not in the cards for this chick, as master delft has pointed out the gear is too far forward and short legged to bring it aboard ship. To change that that would ruin its mass centralization, which would compromise its manueverability, The J-31 is to be your Navy fighter, to the engineers eye it is obvious, and it has been designed to fullfill this role, with gear and plenty of wing for its size, and stealth shaping. Wish our own Navy had gone ahead with a Navalized Raptor, but alas they choose a different path, putting their money on JSF, the J-31 shows us what might have been, right Jeffy?
