摘要
运输类飞机适航标准规定APU冷却系统飞行试验是APU系统适航取证试飞必须进行的科目之一。以某型民用飞机的APU冷却系统为对象,研究一个典型飞行剖面内APU冷却系统相关温度参数的变化情况,对试验结果进行了分析,提出APU冷却系统适航验证试飞方法。
The lfight test of an Auxiliary Power Unit （APU） compartment cooling system is one subject of the certiifcation tests that must be demonstrated according to airworthiness standards for transport category airplanes. On the basis of an APU cooling system, a whole typical lfight proifle temperature data were studied. The methods of airworthiness demonstration lfight test about APU the cooling test was determined on the basis of analyzing the test results.
