基于标准分析军用飞机实验室淋雨试验参数设计

目的对军用飞机淋雨试验进行降雨参数设计,为军用飞机实验室淋雨试验参数设计提供参考。方法采用逐一分析,横向对比的方法,对国军标中部分与淋雨试验相关的六个标准,以及国外的三个标准,在降雨强度、雨滴直径及降雨方向等的参数设置进行分析。结果总结降雨强度设计的规律以及各标准在实验室淋雨试验设计时的作用,给出飞机水密性淋雨试验和除雨性能淋雨试验的部分降雨参数设计。结论给出的降雨强度参数符合各标准的要求,所总结的规律建立在深层理解各个标准的基础上,为军用飞机实验室淋雨试验参数设计提供了参考。

Analysis of Parameters Setting in Military Aircraft Laboratory Rain Test Based on Standards

Objective To design rainfall parameters for rain test of military aircraft rain test, and finally provide reference for parameters setting for laboratory rain test of military aircraft. Methods The six GJB standards and other three foreign standards were analyzed individually, and compared in parameters including rainfall rate, droplet size, duration time, rain angle, etc. Results The rules on design rainfall intensity and roles of each standard in designing laboratory rain test were summarized. Some rainfall parameters for rain test for water tightness and rain removal performance of aircraft were given. Conclusion The given value on rainfall intensity meets the requirements of all the standards. The rules summarized are established based on in-depth understanding of each standard. All these provide reference for parameters setting for laboratory rain test of military aircraft.
