RAM技术在隐身飞行器薄型翼设计中的应用

APPLICATION OF TECHNOLOGY OF RADAR ABSORBING MATERIALS IN DESIGN OF THIN WING OF STEALTH AIRCRAFT

雷达吸波材料（ＲＡＭ） 技术是隐身技术中的重要技术之一，并且在隐身武器，尤其是隐身飞行器系统设计中得到广泛应用。本文首先简要阐述了雷达吸波材料吸波的基本原理，然后以隐身导弹薄型弹翼的低雷达散射截面（ＲＣＳ） 设计为例，探讨了涂覆型雷达吸波材料涂覆方案的设计思想和方法，最后给出一部分隐身飞行器薄型翼面低ＲＣＳ设计的样例。

Technology of radar absorbing materials (RAM) is one of the important stealth technologies,and widely applied in stealth weapons,especially stealth aircraft systems.In the paper,the absorbing basic principle of radar absorbed materials is firstly briefly discussed.Then the coating project for low radar cross section (RCS) is also studied.Finally,some examples of low RCS design of thin wing of stealth aircrafts are provided.
