Dizajn koji je izgubio
Slabo se vidi ali je imao duplo delta krilo
Citat:The aircraft has a main double delta wing with tailplane and the addition of canards at the front. The design philosophy then was to achieve maneuverability over stealth. The PLAAF had set a requirement for 60 degrees angle of attack, similar to the F-22. To reach the goal, the designer Li Tian chose the three-wing layout. It is said that the Snow Owl had an angle of attack of up to 65 degrees during wing tunnel testing.
However, the shape of the aircraft lead to several weaknesses. First, the selection of the double delta creates a possible reflector for radar returns on the leading edge. In order to have three sets of wings, the fuselage is much longer compared to the J-20. This lead to heavier weights and increase demands on the engines. To reduce the overall weight, engineers at Shenyang reduce the size of the radome. This size of the radar was therefore smaller compared to Chengdu’s winning design.

djox ::Kazu modifikovan
В Китае создали новую модификацию истребителя пятого поколения J-20
https://voennoedelo.com/posts/id5810-fhkytwu6vh0rq......ru%2Fnews
Spominju TVC AL-31 i da sa 4 linije mogu da prave 4 aviona mesecno.
Citat:Among the major improvements are the introduction of a thrust vectoring capability, which allows improved flight handling and characteristics.
The new J-20B is said to still use Russian-made Saturn AL-31 jet engines as China has failed to complete development of a locally-made engine called the WS-15. According to reports, the WS-15 has not met requirements although Chinese engineers believe it would take one or two more years to complete the engine development.
Only then will the J-20B be fitted with the locally-made engine, which is the ultimate goal of the project.
The Chengdu J-20 is China's attempt to have a fighter that has similar capabilities as America's Boeing F-22A Raptor, and is expected to be ordered in significant numbers by the People's Liberation Army - Air Force (PLAAF) as it increase its modernization phase to replace older generation, obsolete fighter aircraft.
According to reports, Chengdu Aerospace Corporation (CAC) currently has a 4 production lines, which has a combined production capability to produce 4 J-20 aircraft a month.

Ukoliko bi cena ovog aviona bila prihvatljiva, da li bi u nekoj buducnosti odgovarao sa RV Srbije?

^ a da li bi uopste Kinezi prodavali njega? Rade na J31, mislim da je on za izvoz, a ovo ne.
