摘　　要：建立了直升机刚体运动的六自由度仿真模型。用试飞数据进行参数识别,建立了气动导数数据库并以此计算气动力;将仿真结果与试飞结果对比,并进行了直升机机动飞行仿真计算。结果表明:六自由度仿真模型能够得到较好的仿真结果。A six-degree simulation model of a helicopter is established in this paper. The aerodynamic data are calculated with derivatives that can be identified from some flight-test data. The six-degree model is compared with the result of flight-test. And some maneuver flight simulations are calculated with the six-degree model. These results show that the six-degree model is good for the flight simulation of the helicopter.
