摘要
滚转侧滑耦合是直升机飞行品质试验的重要内容。结合某型直升机的飞行试验,通过参数辨识及数值仿真,给出了不同气动参数下直升机滚转侧滑耦合响应结果,并对气动参数对直升机滚转侧滑耦合及飞行品质的影响规律进行了分析总结,对后续直升机品质试飞有着重要意义。
Rolling sideslip coupling is an important part of the helicopter flight quality test. Combined with the result of the helicopter flight test, the helicopter rolling sideslip coupling response curve with different aerodynamic parameters was shown, through the method of parameter identification and numerical analysis. And the influence of aerodynamic parameters on helicopter rolling sideslip coupling and flying quality were analyzed and summarized. It has important significance for the subsequent helicopter flight quality test.
