随着科技的不断发展,电传控制已成为民用客机的标配。为验证电传飞机满足适航条款及航行运营需要,民用飞机申请人需采用不同的验证手段,其中,试飞是非常重要的验证手段之一。飞行控制系统作为飞机的重要子系统,其试飞主要验证飞行控制系统的功能及性能等。而试飞数据作为验证适航条款的依据,经常受到噪声污染。同时,试飞时还会受到气流等干扰因素影响,严重影响飞控系统的性能验证。基于小波理论,消除了试飞数据中的噪声。试验结果表明,经数据处理后的试飞数据完美验证了飞行控制系统的性能。
With the continuous development of science and technology, telex control has become the standard of civil airliners. In order to verify that DTVs meet the requirements of airworthiness and navigation operations, civil aircraft applicants need to adopt different verification methods. Among them, flight test is one of the most important verification methods. Flight control system as an important subsystem of the aircraft, the main test flight test flight control system functions and performance. The test flight data as a basis for validating airworthiness terms, often subject to noise pollution. At the same time, the test flight will be subject to interference factors such as air flow, seriously affecting the performance verification of flight control system. Based on the wavelet theory, the noise in the test data is eliminated. The test results show that the data processed flight test data perfectly verify the performance of the flight control system.
