吸波材料在飞行器隐身设计中的应用研究

Research about Designing Stealth Aircraft by Using Radar Absorbing Material

基于多目标优化理论,提出雷达吸波材料在物体表面涂敷位置的优化设计方法。利用电磁波的干涉原理和材料的吸波性能,通过设计吸波材料在飞行器表面的涂敷位置,研究局部涂敷吸波材料所能获得的隐身效果。以某飞行器模型为例开展吸波材料隐身技术研究,实现了雷达散射截面减缩与材料增重之间的优化与折衷。

Based on the multi - objective optimization theory, radar absorbing material is built up. According to the interference capability of materials, stealth performance of the aircraft can be some local positions. A representative fighter is researched as an the optimization design model on spray positions of the phenomenon of electromagnetic wave and the absorbing improved by painting the radar absorbing material on example, and the optimization is realized between improving stealth performance and reducing weight.
