摘　　要：研究了进气道/发动机相容性试飞中总压畸变数据的采集与处理方法,详细介绍了传感器选型、测点布局、受感部设计、测试及采集系统构建的要点,开发了通用动态数据处理软件,并重点研究了动态总压数据处理方法和参数选择问题。通过某型飞机/发动机的进气道/发动机相容性试飞应用及其数据处理表明:提出的测试与采集方案合理可行,工程应用情况良好;动态数据处理中应合理选择截止频率、滤波器阶次以及滤波函数。The methods on acquisition and processing of total pressure distortion data in inlet/engine com- patibility flight test were researched. The sensor selection, station distribution, the rake design, and data ac- quisition system construction were specified. General software for dynamic data processing was developed, data processing method and parameter selection were emphasized. Applying the methods to an inlet/engine compatibility flight test project, final results showed that the measuring and processing methods were rea- sonable and feasible, cut-off frequency and filter order and filtering function should be carefully selected in dynamic data processing.
