对粉浆浇注熔硅天线罩结构在3.7～5.0M时淋雨滑车试验结果作了最后评估.其结果为:在霍洛曼空军基地利用滑车轨道设备进行的试验证明,对相同的法向速度分量来说,粉浆浇注熔硅材料的最大冲蚀率变化系数为3;高纯度粉浆浇注熔硅的雨水冲蚀极限速度约为500m/s;法向速度分量超限时,天线罩出现重大损伤;硅树脂防潮密封胶DC808和DE SR80可能不会严重影响雨水冲蚀性能;建议在自然雨区中飞行的导弹,其碰撞角应受控制,以使天线罩上的自由流的法向速度小于500m/s.
The result of the test of the rain-tackle test results when the structure of slip-casting silicon-melting radome is 3.7 ~ 5.0M is as follows: the test carried out on the trolley track at Holloman AFB proves that for the same normal velocity Component, the coefficient of variation of maximum erosion rate of slurry-cast molten silicon material is 3; the erosion limit speed of rainwater of high-purity slurry-cast molten silicon is about 500m / s; when the normal velocity component exceeds the limit, the radome has a significant Damage; Silicone moisture sealants DC808 and DE SR80 may not significantly affect rain erosion performance; it is recommended that missiles flying in a natural rain zone have a controlled collision angle such that the normal velocity of free flow on the radome Less than 500m / s.
