J-20 specifications and engines and AESA


五代机的几大性能: 4S
4s,即:Stealth(隐形);Super Sonic Cruise(超音速巡航能力);Super Maneuverability(超机动能力);Superior Avionics for Battle Awareness and Effectiveness(超级信息优势)
歼20是成飞研发的,是重型战斗机,高性能,远航程,但是造价高,不易大量建造,类似于美国的F-22;
歼31是沈飞研发的,是轻型战斗机,性能不错,航程适中,性价比高,可以批量装备,类似于美国的F35。这是为了高低搭配。
歼击机,即用于在空中消灭敌机和其他飞航式空袭兵器的军用飞机,也称战斗机。第二次世界大战时期曾广泛称为驱逐机。
歼击机的主要任务是与敌方歼击机进行空战,夺取空中优势(制空权)。其次是拦截敌方轰炸机、强击机和巡航导弹,还可携带一定数量的对地攻击武器,执行对地攻击任务。歼击机包括要地防空用的截击机,但自20世纪60年代以后,由于雷达、电子设备和武器系统的完善,专用截击战斗机的任务已由制空战斗机完成,截击机不再发展。歼击机是航空兵空中作战的主要机种,也可用于执行对地攻击任务。
China’s stealth fighter jet is going into mass production after a key upgrade
A modified version of China’s first stealth fighter jet, the J-20, has formally entered mass production, with upgrades earning it a place as a fifth-generation fighter jet, according to a military source close to the project.
The moment was marked at a ceremonial unveiling of the modified J-20B stealth fighter jet on Wednesday attended by many senior military leaders including Central Military Commission (CMC) vice-chairman General Zhang Youxia, the source said.

“Mass production of the J-20B started on Wednesday. It has finally become a complete stealth fighter jet, with its agility meeting the original criteria,” the source said. “The most significant change to the fighter jet is that it is now equipped with thrust vector control.”
Thrust vector control (TVC) allows pilots to better control the aircraft by redirecting engine thrust.
In 2018, China debuted its J-10C multirole fighter — fitted with a WS-10 Taihang engine — at the China air show in Zhuhai, putting the aircraft through its paces in a performance that indicated that China had succeeded in thrust technology.
While the TVC technology had been applied to the stealth fighter, the J-20B would still use Russian Saturn AL-31 engines because more work needed to be done on China’s WS-15 engine, the source said.
Chinese engineers have been developing high-thrust turbofan WS-15 engines for the J-20, but that work has fallen behind schedule.
“The Chinese engine designed for the J-20s still failed to meet requirements, but its development is going quite smoothly, and it may be ready in the next one or two years,” the source said.
“The ultimate goal is to equip the J-20B fighter jets with domestic engines.”
China was thought to have built about 50 J-20s by the end of 2019, but problems with the jets’ engines delayed further production plans.
