民机雨刷性能验证研究

Research on Civil Aircraft Wiper Performance Validation

针对某型民机雨刷系统性能验证过程中大雨气象稀少的问题,提出一种综合计算、地面模拟试验和飞行试验来表明其性能满足设计要求的方法。即通过计算和飞行试验表明雨刷压紧力、驱动力矩满足设计要求,通过计算和地面模拟试验表明雨刷刮刷速度满足设计要求。方法最终在某型民机雨刷系统性能验证上应用并获得成功。

Aimed at the situation that heavy rain is infrequent during civil aircraft windshield wiper system flight test,this paper used calculation method,ground test and flight test to validate the performance of civil aircraft windshield wiper system. The method was as follows： utilizing calculation and flight test to validate wiper arm tip force and wiper motor driving moment,utilizing calculation and ground test to validate wiper sweep speed. Finally,this method was successfully applied on one civil aircraft windshield wiper system performance validation.
