Radar scattering characteristics and RCS reduction of utility helicopter

  • 摘要: 采用物理光学法和等效电磁流法作为RCS(Radar Cross Section)数值计算方法,通过对某飞机模型的实验测试,验证了算法的有效性.建立了某通用直升机的几何外形模型,计算RCS特性并分析其重要散射源.进行机身外形和旋翼的RCS减缩研究,提出了通用直升机隐身外形设计方法.改形后全机雷达散射水平在头(尾)向和侧向分别降低至原型的10%和1%,且静稳定性及有效容积基本不变.通用直升机进行外形隐身设计后,旋翼成为全机的重要散射源(特别在头向及尾向),还须采用其他方法进行RCS减缩.
