大气运动对飞机盘旋性能试飞的影响

Influence of atmospheric motion on circling performance flight test of aircraft

针对盘旋性能试飞时大气运动引起的飞机机械能量转换的问题,对飞机盘旋过程中大气运动的影响展开了研究,提出了一种在盘旋性能试飞数据分析时,利用设计数据进行差量修正来消除大气运动干扰的方法。试飞结果表明,该方法可有效提高数据处理结果的精度,对同类试飞问题的分析具有一定的指导意义。

For the problem of mechanical energy conversion caused by atmospheric motion during circling performance flight test,the influence of atmosphere motion during circling flight test was studied,and a data reduction method of circling performance flight test was proposed,which could be used for eliminating atmosphere motion interference by design data.The actual flight test results show that the method could effectively improve the accuracy of the data-processing results,and it also important for guiding the analysis of similar flight test issues.
