Re: New JF-17/FC-1 Fighter Aircraft thread

JF-17 has more complex vortice generation and management compared to an F-16 as evidenced by convex LERX which is preferred in newer fighters like the Hornet and fifth gen fighters over concave ones like the F-16's. Vortex creation and management is what aerodynamically separates 4th generation fighters over 3 and 3.5 ones. JF-17 also has fly by wire. And it has one fifth generation feature, DSI.

The F-16 and the F-18 are both 4th generation fighters.

Basically, a fourth generation fighter is an aircraft designed after the 1970's to the 1990's that have a emphasis on manueverability and performance.

I don't think vortex generation by LERX alone places JF-17 ahead of F-16 in generation terms, (also as JF-17's wing and tail structure are quite based on F-16). In that way LCA's movable slats should also qualify it in 4.5 generation.

JF-17 has FBW but not flight-control that controls other parts of the aircraft without the pilot's knowledge to constantly stabilize the aircraft. This is because JF-17 is not unstable. DSI is a 5th generation feature but the absence of some 4th generation features makes generalising JF-17 difficult.

FC-1 is unstable in pitch axis.

Re: New JF-17/FC-1 Fighter Aircraft thread

unstable platform doesnt equal a 3th generation fighter, it takes more than one characteristic for it to fit into a 3th generation fighter. The time of design also doesnt reflect its generation. Being hypothetical a Mig-21 based design was developed at present would it be considered a 3th generation fighter. NO. I'll put the JF-17 as an early 3th generation fighter, and J-10 near the 3.5th generation. JF-17 was constructed to be a more affordable F-16 variant.

To my knowledge, JF-17 is not unstable in the pitch axis.
DSI is indeed a good development, but claims that it is at par with JSF need to be reconsidered because the JSF also has VTOL and TVC, which would surely I think, call for much more sophisticated intakes than in JF-17.

Wrong. The JF-17 is indeed unstable in the pitch axis. When the first ever prototype was introduced, its flight control system was FBW on the pitch control, but retained manual on the roll axis. Later prototypes switched to FBW on the roll axis.

And Why no body is answering my question? What is current status of project?How many in production? How many in trial?What about Avionics?

Sorry man, sometimes, the simple answer is that no one knows.

Agreed! Seems to be the case here as well. Actually after March 08 there is a strange kind of silence from CAC and PAC both. I am unable to get a clue either it is secrecy or ????

Only thing I know is that in Pakistan, JF-17s have completed the basic flight manouvres and are engaged in serious high manouvres.
