摘要
为满足耐高温(150℃)宽频带(18~40GHz)的需要,选用石英纤维织物、聚砜改性环氧树脂和Nomex蜂窝芯为主要原料研制机载雷达罩,其单程平均功率透过系数≥87%,单程最小功率透过系数≥76%,力学性能满足飞行安全要求。
To satisfy a radome that can resist the temperature of 150℃ and work at the band from 18 GHz to 40 GHz, the quartz fabrics,polysulfone modified epoxy resin and honeycomb core were selected and used to prepare the radome. The average single pass power transmission efficiency can reach greater than or equal to 87% and the minimum efficiency can reach greater than or equal to 76% ,the mechanical strength can meet the flight safety demand.
