摘要 本文对一种与发动机舱融合设计的直升机进气道在不同的极化方式、不同终端、不同攻角和方位角下的电磁散射特性进行了实验研究,分析了各种状态下雷达散射特性。研究表明,该类进气道RCS在垂直极化方式时比水平极化方式小;采用短路终端时的RCS明显要比采用叶片终端时高;近侧飞时(90°~105°)比前飞和近倒飞状况下的雷达散射截面大;在攻角分别为-10°,-5°,0°,5°,10°的实验中,当攻角为10°时的RCS值较小,而当攻角为-5°时的RCS值较大。 An experimental study of the radar cross section in a helicopter inlet syncretized with engine cabin was completed in different polarization ways,terminals,attack angles and azimuth. Meanwhile,the RCS characteristics were also analyzed at various states.The results indicate that RCS of this inlet is lower in vertical polarization way than that in horizontal polarization way,and higher in plate terminal than in blade terminal.The radar cross section at nearly sideslip is larger than that at front flight and nearly backward flying.In the experiments of different attack angles (-10°,-5°,0°,5°,10°),the RCS at 10° is relatively low,and at -5° is relatively high.
