China collected four prototype fifth-generation fighter

The Chinese Chengdu Aircraft manufacturing companies gathered four layout promising fighter J-20, The program of flight tests that began in January 2011. As reported by Jane's, at the present time only two models of aircraft hull numbers 2001 and 2002, making flights, while others are participating in ground tests.

In one prototype of the flight has two different motors. Presumably, some of them — the Russian production. This may be the powerplant of the AL-31F or AL-41F. In 2011, China had acquired 150 power units of the AL-31F and AL-31FN. 2nd sliderWS-10A Chinese production. At the other airfield layout established Chinese engines WS-10A, the creation of which the company does Liming Aeroengine Manufacturing Corporation.

The program design J-20 progressing very slowly and with difficulty. According to the Ukrainian and Russian professionals, which refers to Jane's, Chinese spices, namely, have not been able to finalize a series of engines WS, so that they can be used on the new fighter. These power plants do not differ highest reliability and can not give out huge thrust. In addition, China has not yet managed to pick up a fairly strong material, that increment TBO WS-10A.

In addition, the shape of the bow, the cockpit canopy, front horizontal stabilizer and slat on all 4 different layouts. Rather, it means that the engineers Chengdu can not choose the best design solution that would allow to find a middle ground between aerodynamics and discreet.

Fighter J-20 made on the aerodynamic configuration "duck" with high-lying delta in terms of wing-fuselage mating. All-moving fins have a large camber angle from the longitudinal axis. Nacelles are placed at the edges of the fuselage under the wings. Technical Specifications J-20 yet unidentified.
