1- Have you seen J-10 manufactruring process, I highly doubt that. Did u were part of LAVI project... I don't even think it as a possibility so please restraint from making blind judgment.What do the J-10 and the Lavi have in common? Configration? Looks? Have you seen the manufacturing process of the J-10? The Lavi is internally a F-16 and externally still a F-16 with delta configration. You think you'd get a J-10 if you placed the Girpen's ducts on the bottom? No! The Girpen is redesigned F-16 internally! It may come out looking like something else, but its the fabric inside that makes the aircraft. Every aircraft has something in common, expecially on the out side.
IAF is happy with the low mantenance of the Mirage 2k. But that doesn't mean that they designed the Tejas with Mirage deltas! The Mirage 2k is a metal airframe with LRU. The Tejas is a Compisote airframe with exstensive LRU's. Tejas wings are widly uncommon and new. Manufacturing process for the wings arrived from Italy! The mirages delta give it high speed agility while comprimising low speed. Tejas does both, creating greater drage than these, which is why Gripen, Rafale, J-10, Typhoon have greater top speeds. The Deltas produce great amounts of constant drag in the case of Tejas, while the Canards are used for greater lift when needed, to produce drag while they turn static with the airflow at top speeds. Tejas wings do it at constantantly to provide lift and agility at low speeds. Thus no need for canards or extra weight. The wings are stronger, low mantiance even compared to deltas on the Mirage. But on the positive side, they provide the low speed handling capability. On the negative side, it produces drag and gives the Tejas lower top speed. The shoulders on the wing of the aircraft push up like Canards. HAL at first at concept expected a Gripen like design, similair on the inside and out. But eventually because of their moto to redisien the wheel they added Cranked Delta wings and removed the Canards. Reducing weight and increasing wing payload and fuel compacity. At take offs and landings the Tejas is very fuel effiecient. Comprimise.
What you said is that the J-10 is stolen Lavi technology. I'm not deneing the Israelis gave them blueprints, but they didn't learn much from looking at. Jews didn't go to China and tell them how to assemble like Lockhead. Russians did, but they gave away their soviet era techniques, Chinese used these methods on their J-10s. Look at the amount of bolts and rivits in the J-10 and new aircraft in this decade. Doesn't seem like the same workmanship. Because they aren't. Differnent build. The way the Chinese built their aircraft is very similair to a build of a J-7 or Su-27. Heavy metal airframes that require a lot manpower. Cost of airframe is dropped but mantaince is high.
HAL assembled aircraft before. But had no dedicated assembly line. They started with the newest avaliable technology on the market. China does not have that luxery. It is why you here of so many Chinese spyies. They are left in the dark. HAL learnt from the Tyhpoon project, Rafale, Girpen etc... which is why Tejas just like these aircraft have extensive LRUs and compisote materials. Cost would have been the same if the manufactured a metal airframe or compisote. But the former is less mantiance heavy. HAL will import compisote material manufacting machines and expertise. This just means that the Tejas, has more value as a project and fighter jet.
Aircraft don't have to be the greatest or hottest. They just have to get hte job done at the lowest possible price in the end. If you can't understand this than theres not point in me posting again and agian.
The Tejas and J-10 are in differen't leagues. The J-10 has a heavier airframe of mostly metal. Many hard points, powerfull engine, with greater take off time. Canards give it low speed agility, something you don't need if you were designing a interceptor to fire BVR missiles because its just added weight. The four pylons under its fueslage carry dumb bombs. A dead giveaway for what it is intended to do. I think the PLAAF have large amounts of gravity bombs and this is the aircraft they can use. Its no quick reaction interceptor like the FC-1 or Tejas. Its not light, it doesn't have a low RCS, even with the DSI to reduce this. Of course it has BVR ability, but so does a J-8. J-10 has to many arms for a interceptor and too small as a dedicated airsuperioty like the Su27 which has range and two engines for the job.
FC-1, short reaction time till launch. Not many hardpoints, ideal for carrying the correct amount for payload vs thrust. Simple J-7 assembly line with advanced avoinics. Small RCS, no large vents or too many external stores. Ideal interceptor/multirole aircraft.
Tejas, Low RCS, quick reaction, decent payload and range. Interceptor/multirole aircraft. This is what PLAAF wanted before the sanctions. Now they use a two teir solution which costs more but what are the other options? Where are they going to get F404 manufacturing line?
2- Like Tejas J-10 also uses composites and remind you only parts of airframe can be made of composite. Even F-22 has some parts made of metal.
Constructed from metal alloys and composite materials for high strength and low weight, the airframe's aerodynamic layout adopts a "tail-less canard delta" wing configuration.

3-Do you have any proofs that Lavi documents were shared with China. On one hand you are saying that one can't learn much by looking at drawings and on other hand you are making it a contribution in J-10 project.
4- Bolts are used extensively even in 5th gen fighters.
One MoreDebbie Johnson (foreground), Stacey May and Brett Chandler check fuel cell seals in a Raptor wing box at the Boeing F-22 Assembly Center in Tukwila.
Boeing, Lockheed Martin seek to save F-22 fighter program - Puget Sound Business Journal (Seattle):
Bolt and Rivets work going on F-22
So having bolts don't prove a fighter assembly less sophisticated.
5- J-10 is no longer an interceptor or air superiority fighter. It is a multirole fighter so it does not need specs of a interceptor like J-7 or LCA etc.
6- Was HAL involved in projects like Rafale, Gripen,Typhoon etc? What HAL really learned... only thing i can fore see in HAL projects is DELAY. (Sorry no offence was intended)
7- Dumb bombs on J-10.... Why don't chinese use supersonic J-5 for that purpose. Ever heard PL-12, PL-11, Pl-8, L-500Js,LS-6, LT-3 etc? I doubt that. Otherwise you had not made that sort of comments about J-10's armament.
8- JF-17/FC-1 is only a multirole fighter. Interceptors are not multirole fighters; So don't misguide others using them alternatively.
Multirole Fighter A multirole (or multi-role) combat aircraft is an aircraft that can be used as both a fighter aircraft and a ground attack aircraft. They are lighter and less powerful than air superiority fighters.

Interceptor An interceptor aircraft (or simply interceptor) is a type of fighter aircraft designed specifically to intercept and destroy enemy aircraft, particularly bombers, usually relying on great speed.

9- I think WS-10 is going to be matured in couple of years. It is already under testing on J-8 and J-11s So China wouldn't need a foreign engine.
