In order to improve the survivability of the aircraft,conceptual design and radar cross section(RCS) performance research are done. The CATIA software is used to design the 3D digital model of the shipborne early warning aircraft, and some measures are taken to reduce the RCS characteristics of the early warning aircraft at the same time. Based on the physical optics method and the equivalent electromagnetic flow method,the aircraft's RCS characteristics and strength distribution characteristics are simulated numerically, and compared with the foreign advanced shipborne early warning aircraft. The simulation results show that under the X radar band, when the incident wave pitching angle is 0?, compared with the foreign advanced shipborne early warning aircraft, the forward RCS average value of the conceptual shipborne early warning aircraft is reduced to 24.49%, the lateral RCS average value is reduced to 5.04%, and the backward RCS average value is reduced to 39.26%. The research results of this paper are expected to provide theoretical basis and technical support for the conceptual design and the stealth design of the shipborne early warning aircraft. 相似文献

<正>预警机,也称空中指挥预警飞机,在现代战争中愈来愈扮演着"空中作战指挥官"的角色。平常军迷们对比两国的空战实力,通常会拿两国主力战斗机的性能和数量进行对比。其实,正如"一头狮子能把一群绵羊带成一群狮子",而"一只绵羊能把一群狮子带成一群绵羊"一样,预警机这个"指挥官"的素质和发挥的作用在现代战争中经常起着决定性的作用。预警机的发展可以追溯到第二次世界大战后期。当时美国海军根据太平洋海空战的经验和教训,认为及早发现接近舰队的敌机十分重要。但 相似文献

在现代几场海上局部战争,尤其是海湾战争中,预警飞机得到了淋漓尽致的发挥、充分有效的应用。多国部队共投入了10架E-3A(美国5架、沙特阿拉伯5架)、24架E-2C,以及2架最新研制的E-8A雷达系统侦察预警飞机,这些海空战场上的“千里眼”与侦察卫星等其它侦察手段相互配合,使得伊军稍有行动,便处于多国部队严密的监视之下。可以说,预警飞机是多国部队迅速取胜的关键因素之一。 人们迄今记忆犹新的是,英阿 相似文献
