隐身飞机实现隐身,主要采用三项关键技术,即隐身外形技术、吸波隐身技术和电子干扰技术。其中,最常用的一项是隐身外形技术,它主要是通过改变飞机的外形来尽量减小雷达的反射面积。此外,为了降低红外辐射,隐身飞机还采用了涡轮风扇发动机,并在其尾管中装上红外过滤器,这种装置可以大幅度降低红外辐射,把红外探测距离缩短45％。海湾战争中,美军出动44架F—117A隐身飞机,精确轰炸了巴格达95％以上的重点目标,均未被对方雷达发现,且无一损失。
Stealth aircraft to achieve stealth, the main three key technologies, namely stealth shape technology, absorbing stealth technology and electronic jamming technology. One of the most common is the stealth shape technology, which is mainly by changing the aircraft’s shape to minimize the radar reflection area. In addition, in order to reduce infrared radiation, the stealth aircraft also uses a turbofan engine with an infrared filter in its tail pipe, which reduces infrared radiation by as much as 45%. During the Gulf War, the U.S. military dispatched 44 F-117A stealth aircraft and accurately bombed more than 95% of the key targets in Baghdad. Both were not discovered by the other side’s radar and there was no loss.
