超音速下压力分布测量飞行试验研究

本文主要对超音速下的压力分布测量飞行试验技术进行了研究。文中首先对压力分布测量的试验方法、测试原理、试验飞机、测试设备等进行了简要介绍。然后重点研究了飞行试验数据处理方法，得出了超音速飞行试验中压力系数的计算公式。最后给出了飞行试验结果误差分析，并得出了测量结果不确定度的计算方法。国内在超音速气动力飞行试验领域内的研究还非常少，本文中所给出的计算方法可为今后的飞行试验提供参考。

In-Flight Investigation of Pressure Distribution Measurement in the Supersonic Flow

Flight test technology of pressure distribution measurement in the supersonic flow has been discussed in this paper. This paper first briefly introduces the test method, test principle, test aircraft and test equipment of the pressure distribution measurement. Then focus on the flight test data processing method, and reached the calculation formulas of the pressure coefficient in the supersonic flight test. Finally, gives the error analysis of the flight test, and reached the calculation method of the measurement result uncertainty. The study of the supersonic aerodynamic flight test is very little in the domestic, the calculation method given in this article can provide reference for future flight tests.
