Looks a lot like a F35/F22 mix?

looks suspiciously similar to the Raptor. I would not be surprised if they copied some design elements from it, I wonder how??  
Otherwise it looks pretty sick and a worthy contender for a next gen fighter.



Chance favors the prepared mind.

I would say it's a twin-egine F-35 instead of a Raptor

Not likely. It is more likely that the Chinese simply don't have a sufficiently powerful enough engine to make this a single engined aircraft.

While a distinct possibility, its more likely that they just didn't have the design requirements that limited the airframe to a single engine - remember that the F-35 started out a STOVL design and became three variants from that (the F-35B begat the A and C variants), with the single engine requirement stemming from the STOVL limitations. Without a STOVL requirement, it makes more sense to have two engines for carrier operations (which this airframe is likely to be orientated toward).

It would probably be a real pain to connect 2 engines to a lift fan transmission. From what I read, Lockheed bought technical info from Russia from the YAK-141 for the lift nozzle. 2 engines would again complicate things. A single engine was pretty much mandatory for the F-35B, thus the remainder of the fleet for commonality. The F-35 also got its hunch back because the F-35B needed the engine to be farther forward to connect to the lift fan transmission to avoid a drive shaft. You remove the Bravo influences on the F-35 it would probably look a lot like the Chinese offering.

Ah the problems inherent in designing a 'multi role, multi variant' aircraft.

Still cheaper than developing 3 different aircraft at once.

Not if the R&D is shared among the programs.

Point out one new fighter program that was not ridiculously expensive. I can. F/A-18EF, but that wasnt really a new fighter. Every current program has been in the works for better part of 20 years. Based on aircraft development trends, all three programs would be way over budget, behind schedule, and having teething issues. So instead of one troubled program, there will be 3.

lol, the F-35 is the biggest sharing of R&D ever. 3 programs using as much common resources, hardware, and research as possible.
