飞机吊舱雷达天线罩的研制

Development study of airplane hang module radome

通过对树脂传递模塑 (RTM )用 45 0 3A双马来酰亚胺 (BMI)树脂的改性 ,筛选出一种新型改性BMI天线罩用树脂 ,既保持了原树脂的介电性能 ,又满足了手糊玻璃钢成型工艺的要求。用它成功地研制出飞机吊舱雷达天线罩 ,达到了技术性能指标 。

With the 4503A BMI resin applied in RTM process was modified, a new modified BMI resin was obtained for making radome. Not only the dielectric properties of the original resin were kept up, but also it was satisfied to hand lay-up moulding. In the paper, the airplane hang module radome was developed with this resin, the dielectric performance were achieved, its shaping process and mold design was introduced.
