电传直升机总距高度响应分析
|
摘要
电传直升机总距高度响应特性是直升机飞行试验的重要内容。通过飞行试验及数值仿真,给出了不同辨识方法、大气环境、离地高度下电传直升机高度响应特性的评价结果,并对影响电传直升机总距高度响应结果的因素进行了具体的分析,对指导电传直升机飞行试验具有重要意义。
The Fly-by-wire helicopter's collective height response is an important part of helicopter flight test. Through the flight test and numerical simulation of the helicopter,the results of the helicopter height response with different identification methods,atmospheric environment and ground height were given.And the factors that affect the height response of the helicopter were analyzed. It has guiding significance for the Fly-by-wire helicopter flight quality test.
