传统的稳态飞行试验方法,已经不适应现代飞行试验研究的要求了。为了缩短试飞周期,降低飞行试验费用,非稳态飞行试验和参数识别技术是目前较为先进的试飞研究方法。然而,它是建立在精确地测定飞机参数和先进的数据处理方法的基础上。本文着重叙述在非稳态飞行试验中,为了提高测试精度,要正确地选择测试系统、注意校准方法、正确安装测试设备、仔细地考虑仪器的零点漂移、正确采用迎角的测量方法。最后讨论了陀螺平台及集成式敏感测试系统在非稳态飞行试验中的应用。
The traditional method of steady-state flight test has not met the requirements of modern flight test research. In order to shorten the test flight period and reduce the cost of flight test, unsteady flight test and parameter identification are the most advanced flight test methods. However, it is based on the precise measurement of aircraft parameters and advanced data processing methods. This article focuses on non-stationary flight test, in order to improve the accuracy of the test, we must correctly select the test system, pay attention to the calibration method, the correct installation of test equipment, carefully consider the instrument zero drift, the correct use of angle of attack measurement. Finally, the application of gyro platform and integrated sensitive test system in unsteady flight test is discussed.
