直升机ACAH响应类型及飞行品质分析

以实际飞行数据为基础,对ACAH响应类型进行建模及验证,对模型中不同气动参数下ACAH的响应曲线特征以及飞行品质进行了仿真分析,明确了M_(Wy)、M_q及M_θ对ACAH响应曲线特征以及该响应类型下直升机飞行品质的影响,对指导直升机ACAH响应类型的设计和考核具有重要意义。

Based on the actual flight data, the ACAH response type is modeled and verified, and the response curve characteristics and flight quality of ACAH under different aerodynamic parameters are simulated and analyzed. The effects ofMWy,Mq andM兹on the response curve of ACAH and the flight quality of helicopter under this response type are clarified. It is of great significanceto guide the design and assessment of helicopter ACAH response type.
