Re: LFC-16 or CY-1

For it to be much cheaper and still have a modern engine and radar, it would have to be mish-mash of off-the-shelf components from other projects. Not saying it can't be done or done well. Still, very surprising.

From what I last heard about of the project, it (so far) uses a WP-13F turbojet engine but for all we know, it could have adopted the more powerful WP-14 turbojet. Since Guizhou also has already thoroughly tested the JJ-9, development was probably not all that difficult aside from testing the canards etc. Given its export intensive nature, it's radar will either be the Italian FIAR Grifo S7 (already tested on the JJ-9) or the domestic KLJ-6F (BVR capable KLJ-6 variant). I doubt such a lightweight aircraft would use the KLJ-7. The guts of the thing are all old fashioned mechanical flight control system with its double-delta wing configuration to approximate features such as LERX which also reduce costs.

Re: LFC-16 or CY-1

I was under the impression that LFC-16 was a demonstrator for some new concepts including side strakes above the wings, movable underfuselage fins, and some other undisclosed vortex management thingies?

No. It was an independant export project by Chengdu in order to continue the series of J-7 to make money.

Since induction of domestic turbofan(WS-10A,WS-13) is lagging behind. It maybe the reason for reviving interest of LFC-16. Don't forget, it can be everything 100% indigenous. Plus if pricing is right, it might be a interesting export after all since it might have increase payload,ground attack capabilites compare to J-7G. Not to mention BVRAAM.

JFC-17 is not developed by Chengdu, but by Guizhou, and according to them, it will be the "most manuevrable fighter in the world".

according to the article,the jet already taken her maiden flight,but the picture appear look more like small model.


Goggle Translation


After the 2004 Zhuhai Air Show, a number of online statistics reached a surprising fact: the most attractive User eye it is not the blue sky became well-known SU-27 fighter, nor is it pretty lightweight L-15 advanced trainer, but rather bizarre appearance on stage in your air show LFC-16 high-agility fighter model.

In fact it is not just interested in China Netizen, even foreign media, this aircraft also showed some interest in the U.S., "Aviation Week and Space Technology" magazine for its evaluation: "It is confusing model" .


Yes, this aircraft will not only shape confusing, confusing numbers, and even its life experience, use all a bunch of confusing issues. So, let us approached the plane and look at history, a common theme behind these fans.

According to the official explanation of your flight, LFC-16 stands for "light (Light) fighter (Fighter) Chinese (China) -16", 16 for your flight's internal numbers. The fighter is your CSC and civil aircraft,
Design
Company "super wing" companies to "Mountain Eagle" advanced trainer based on the body, using side-duck-style layout of the technical design made of lightweight fighter program of high mobility. The fighter program is characterized by: low price, high mobility, the installation of more advanced electronic equipment, are super-fighting-type low-cost models at the same time have the right to attack capability.

Aroused the last air show enthusiasts and professionals pay attention to side-duck layout fighter CY-1 (super-wing one type), in this air show with the name of the re-LFC-16 debut.

It is noteworthy that the aircraft used by the Chinese side of duck pneumatic original layout, with the patented technology such as moving side fins; if the aircraft used in a series of innovative pneumatic technology, including the fuselage side + duck Pneumatic layout, with the moving side fins, and other controllable vortex. Through the application of these techniques can improve aircraft maneuverability and stability, and even to reach the level of propeller aircraft, while mobility will also be greatly improved. Allegedly, the aircraft, if successfully developed, will likely become the world's first fighter maneuverability. In addition the cost of development of this aircraft from the private venture capital funds, it can be said of China's fighter development to create a precedent in history.

LFC-16 used in the fuselage side rather unique, its location slightly below the canard plane, the width of great. Estimates that its role is to have a strong eddy under the large angle of elevation, coupled with the canard vortex, on the wing, inducing a high lift. Help to improve the aircraft takeoff and landing performance and hovering capabilities. Aircraft control and stability improvements, largely rely on the active eddy current control and servo deflection with lateral fins, making the aircraft could not use fly-by and the thrust vector control technology, was able to maintain a stable high angle of attack and better handling. Perhaps the real value of the LFC-16 or its secrecy of the eddy current control technology. This is a new type of aircraft will enhance the fighting capability of great significance.

I believe you have the Guizhou LFC-16/CY-1 mixed up with the similar, but not directly related Chengdu J-7MF.

Re: LFC-16 or CY-1

Well the fact remains, we now of blurry pictures of what seems to be an actual LFC-16 (the article states that they used an existing 'Mountain Eagle' for the body, the 'Mountain Eagle' is ofcourse, the JJ-9) flying in the air. I believe that, while this aircraft probably doesn't really have a place in the PLAAF, it would be quite exportable, especially if the price tag per unit stays around $10 million or less for an aircraft. It's capabilities are unknown but we do know that the double-delta J-7E style wings it possesses are agile enough. The biggest unknown variable right now are the specifics of the radar and engine and also any performance difference created by the canards.

Re: LFC-16 or CY-1

Quote from Richard Fisher's 2002 article titled "China's PLA enlists capitalist competition":

"One of CAC's upstart competitors is the five-year-old Beijing SuperWing Technology Research Institute Co., which came to the airshow to market its CY-1 multi-role fighter. Like the J-10, the CY-1 is a canard-delta multi-role fighter with F-16-like performance. But it uses a novel aerodynamic "side stake" to allow the plane to achieve stable flight without using expensive computer-driven, fly-by-wire systems needed by the J-10. When you dig a bit, however, you find out that Beijing SuperWing only sells concepts; it does not actually make airplanes. But they do need investors, and with the right capital are confident of generating a prototype in five years.

Not too far away, one potential partner to produce the CY-1, the Guizhou Corporation, scoffed at the concept fighter, skeptical that it could forgo fly-by-wire systems. They too were pushing a new product, their FTC-2000 trainer, which could also easily be modified into a fighter-bomber to compete with the J-10 and the CY-1.

Neverthless, Beijing SuperWing professed optimism about the CY-1, claiming that the "customer," an airshow euphemism for the PLA, was "very enthusiastic" about its idea. And why not? By simply empowering the company, the PLA potentially gets an inexpensive fighter with reasonable performance without spending their own money -- and in a fraction of J-10's glacial development period. And even if the company fails, the PLA gains, as Beijing SuperWing's managers and engineers will have learned valuable lessons to apply to future projects."


============================

To best of my knowledge, Beijing Superwing only had designs and couple demo models. The "prototype" aircraft shown in the photos may be a radio-controlled model and not an actual manned aircraft.
