民机防冰系统自然结冰试飞技术研究

结合某型民机自然结冰条件下防冰系统的试飞,对试飞所需的测试改装工作进行了总结,并对试飞前需进行的各种安全性评估进行了总结说明,明确了试飞中需考虑的各种构型情况,提出一套循序渐进的自然结冰试飞方法。同时提出了试飞中结冰气象参数的可接受性判据,最后针对自然结冰试飞中结冰气象参数的处理提出了分段等效处理的方法。

Research of Natural Icing Flight Test of Anti-ice System for Civil Aircraft

Based on the natural icing flight test of one civil aircraft, the flight test refit and safety evaluation required by flight test were summarized, and different configuration which flight test needed was listed, and then one kind of fight test method and the acceptable criterion of icing meteorology parameter were put forward. At last subsection equivalent method of data analysis which aimed at icing meteorology parameter were come up.
