--some stealthy jf17 / fc20 changes being discussed on different forums
1]
the engines for the Jf-17 are planned to be 100 KN; therefore two engines would give at leat 200 KN
while the WS-15 engiine is planned to be used on the J-XX and have 180 KN per engine
a single engine WS-15 poowered fighter could be ascaled up Stealthy JF-17
if the same technology is applied to the JF-17's engine (engine thrust upgraded to about 120kn) and the JF-17 is made lighter with composites and controlled by the lighter (no hydralyic fluids) quad fly by wire, it could probably supercuise (a 5th gen essential)
gripen 2000 lb (~1 ton) less than the JF-17 and with a 98kn Engine (F414) it can supercruise -- the ability to fly supersonic without the use of afterburner which results in fuel savings and an increase in range.
if more composites were used and the hydralic replaced with a complete quad fly by wire, and the body slightly redesigned to accomidate it, the JF-17 could probably also supercruise (because the Ws-13 is being upgraded to 100kn range)

If the gatling gun is removed from the bottom and moved to the top, and the central pylong is removed, that clears the underside except for the wheels--wheels away from the body, allow the weapons bay to be longer, and allow the stealthy JF-17 to carry 2 SD-10 or Ramjet BVr missiles, and 2 WVR Missiles
if the wheels are shifted forth out to the wings like in the x-32 and f-35

The F-15SE (silent eagle) demonstated a retrofit to a fourth gen design with internal weapons bay; which brought israeli offers to purchase it (demonstrating not only the feasibility but the desire for an in between platform, to compliment not subvert true fifth gen platforms)

There is also a possibility that China could have a program for other 5th generation fighters, perhaps to include a medium-weight fighter to compliment its reported heavyweight fighter program. In early 2005 a Chinese industry source told the author that the Chengdu Aircraft Co. was considering a “F-35 like” fighter program. But its compelling feature was that it had one engine, an indication that there may be a medium-weight 5th generation fighter program as well. By mentioning the Lockheed-Martin F-35, there is at least the implication that a potential Chinese medium-weight fighter could be built in multiple versions, to include a short-take off and vertical landing model (STOVL), much like the F-35B.

China Aviation Industry Corporation I self-developed, with full independent intellectual property rights of YFC-1E "Xiaolong" stealth all-state aircraft 05 aircraft in its prototype based on the 01.03.04, conducted aerodynamic, structural, and system optimization of the whole The new design, the use of advanced "shell" inlet and dual vertical tail stabilizers innovative technology and application of a number of integrated manufacturing technology, with the most advanced country with high integrated avionics and weapons systems, configure the world's leading The cockpit has a good user interface integrated display device, stealth-type "Fierce Dragon" fighter's overall performance and significantly enhance the comprehensive combat capability.
相对于此前已成功首飞的“枭龙”01架.03架.04架飞机属平台状态的“升级隐身版”，着重于对飞机机体 的研制，主要用于支持试飞、保障飞行安全而言，05架“枭龙”战机达到可实用交付的全状态，完 全可以称之为 “超级隐身完整版”。 The relative success of this first flight before the "Fierce Dragon" 01 .03 .04 aircraft platform is state of the aircraft "upgrade Stealth Edition", focuses on the development of the aircraft body, mainly to support the flight test to ensure flight safety, , 05 "Xiaolong" fighters to be practical delivery of the full state, can call it "super-stealth full edition."
7] gambit--
For reducing the JF-17's RCS, the first thing that must be eliminated is the single vertical stab.A clean F-16 is about one meter square at that distance and this is the unofficial standard. So if there is any attempt to make the JF-17 'stealthy', this is the goal.
