According to information revealed on the expo, aerodynamic performance and stealth performance of Chinese J-31 (FC-31) stealth fighter exceed many traditional fighters, and its avionics system will also be upgraded.
Some other specification of J-31 fighter was also unveiled. The highest speed of J-31 stealth fighter is Mach 1.8, and the largest combat radius is 2000 kilometers, which meet demands for carrier-based aircrafts.
Besides, J-31 stealth fighters owns absolutely independent intellectual property, excellent composite combat performance, single-seat double-engine, twin vertical fin and flying tail, large S-type bending air inlets on two sides, and interior weapon cabins.
Like US F-22 and F-35 fighters, China’s J-31 stealth fighter also features high viability, low radar detectability and low infrared radiation, as well as outstanding electronic countermeasures and low vulnerability design. J-31 also has powerful target detecting capability and outer information composite ability, excellent situation awareness, information sharing ability, multi targets BVR attack, arge off-boresight launching all-round air combat ability, air-to-land and air-to-sea precise attack ability.
With multiple mature technologies, J-31 stealth fighter is expected to be launched for international market in five years, and become a mature and cheap fifth generation fighter by 2024, and thus replace JF-17 block 2 as an exporting fighter jet of China.
