Re: New JF-17/FC-1 thread

@AssassinsMace; I am not singling you out. I am just pointing out the compon missperception & lies which go around various forums (especially Indian as you can guess ... since this whole non-credible fuss was started by Indian media).

J-10 is not 100% complete copy of Levi & how can it be? Much of the avionics & weapon system of Levi was American & China had no way of getting them, so China developed its own. But the Levi blue prints (if they really were given, cause I still have to see the credible proof for that as well) did provide good amount of knowledge & info for China to develop its own 4th generation fighter. Besides there exist different fighters of same league with same basic capabilities (i.e. F-16, Mirage-2000 & MiG-29) but regardless of them being in same league they are different in terms of avionics & weapon systems. So, all fighters look different from inside even if you take one of them for example I am sure you would have a different thing from inside i.e. the F-7 (it is not complete MiG-21, every thing inside is said to be different & of course Chinese).

Re: New JF-17/FC-1 thread

The connection between J-7 and Mig-21 are obvious and no one doubts its a copy. The J-10 looks as similar to the Lavi as it does to the Typhoon and the Rafale. People say that many of the concept changes of a future J-10 will essentially make it a new fighter and not a J-10 variant simply because of the design structure is basically changed. The J-10 is bigger than a F-16 or the Lavi. Isn't that a design difference simply based on size alone? Are the struts we see over the J-10 intake a design flaw of the F-16 and Lavi? Or is a mistake on the Chinese designers? I don't think given the opportunity, and China certainly has had them, China would not give up a chance to look and learn at the F-16 or Lavi in whatever way, but can one really consider the J-10 a copy when there's more dissimilar than similar aspects inside and out? The FC-1/JF-17 is even more dissimilar.

The Frenach Ambasador to Pakistan has confirmed in a news conference after the meeting with the Foriegn Minister of Pakistan today that France is in discussion with Pakistan in relation to possible sale of components for JF_17. Lets see if in coming few days anything matierializes

Re: New JF-17/FC-1 thread

There are also struts between the intake and fuselage of the J-8II and JH-7, and I bet you will see the same struts in the Phantom and MiG-23. The struts are more or less part of the design of the intake, which looks much like the intakes described except from sideways to downward. Thus you can see the J-10's intake has more of a relationship with the J-8II's and the JH-7's.

I know the E-3 is capable of telling the difference between a Toyota Corolla and a Honda Civic, from their electronic emission signatures.....

one can installed a programmable signal generator on a Toyota to mimic EM signatures on a Honda(and vice versa). So that a Toyota would appear as a Honda to the E-3.

I doubt it, but JSTAR ,APG-71 and E-3 can tell the different between wheeled vehcile and tank track just by using radar's doppler beam sharpening.

Re: New JF-17/FC-1 thread

Laugh that Toyota vs Honda claim is utterly ridiculous. You better have a darn good source for that.

Re: New JF-17/FC-1 thread

China's doppler beam sharpening technology may lag behind the US. But thats expected:

In 2001, JL-10A achieved a 32:1 DBS (Doppler beam sharpening) capability, but it still lags behind the 48:1 DBS capability of AN/APG-66, and it was not several years later when the JL-10A was finally upgraded with 64:1 DBS capability like that of AN/APG-68. Around the same time, JL-10A was also upgraded with the capability to simultaneously engage 15 targets and engage 6 of the 15 tracked. By 2004, SAR capability was incorporated, and inverse SAR (ISAR) capability is reportedly under development.

The radar has already been tested and successfully installed on JH-7A Flying Leopard fighter-bombers and is capable of launching a scope of weapons including the as the C-801K anti-ship missile and the Russian Kh-31. The JL-10A will be fitted on the Chinese J-10s and Chinese/Pakistani FC-1s upon customer's requests.

but the Doppler beam sharpening capability on Russian Zhuk ME radar may be comparable to US set.

Crobato Said:


Crobato,
to me it appears that the slant V like flat surface in the fore of intakes(Pt-03) was replaced with a more curved surface flush with rest of curved body around that area (Pt-04) (not standing out like the V surface).

Here are two pictures, one of PT-03 and PT-04.

The difference is that PT-04 features "divertless" engines inlets. Inplace of the conventional ramp of the original two-dimensional intake, the new design features a hump to divert turbulent boundary-layer airflow away from the engine inlet. Diverter plates are used to separate the boundary layer of air that comes off the body of the aircraft in front os the inlet. This is slowed and chaotic air that can choke the engine - all part of the DSI principle in dealing with the boundary layer. The JSF F35 uses the same DSI principle.
