摘要
提出了直升机NR包线拓展试飞方法,包括有动力NR包线拓展及无动力NR包线拓展飞行试验方法,并着重针对无动力NR包线拓展提出了在目标速度直接进入自转及进入自转后增速至目标速度的两种飞行试验方法,进行了飞行结果分析及对比评估,对后续直升机NR包线拓展飞行试验具有指导意义。
The helicopter flight NR envelope expansion method was presented, including powered-on NR envelope expansion and powered-off NR envelope expansion flight test method, and emphatically aiming at unpowered NR envelope development put forward the target speed directly into rotation and enter the rotation speed of growth to the target of the two methods of flight test, an analysis and a comparison between the flight results evaluation, for subsequent helicopter NR envelope expansion has guiding significance for flight test.
