摘　　要：以适合于飞行品质评价的纵列式直升机非线性飞行动力学模型为基础,根据有人驾驶垂直/短距起落飞机军用品质规范(MIL-F-83300)以及军用旋翼飞行器驾驶品质要求(ADS-33E-PRF),对纵列式直升机悬停开环状态下的飞行品质进行了计算分析.按照两种规范的要求,对纵列式直升机的动态响应特性与带宽、操纵特性与姿态敏捷性、轴间耦合以及横向突风扰动影响进行了分析,最后给出了一些有意义的结论.Based on the flight dynamic model suited to evaluate the flying qualities of a tandem helicopter,the open-loop flying qualities of a tandem helicopter at hover were studied by using military specification flying qualities of piloted vertical/short takeoff and landing(V/STOL) aircraft(MIL-F-83300) and handling qualities requirements for military helicopters(ADS-33E-PRF).According to those requirements,the dynamic response characteristics and the bandwidth were analyzed,along with the control characteristics ...
