对某型舰载直升机飞行模拟器飞行仿真系统进行了设计研究。给出了某型舰载直升机飞行模拟器飞行仿真系统的模型框架。定义了建模过程中所涉及的主要坐标系,研究与分析了与主旋翼相关的诱导速度、挥舞角、拉力、扭矩的计算方法,给出了舰载直升机部件气动建模思路。最后,结合舰载直升机数据,对直升机飞行模拟器飞行仿真系统对舰载机飞行员的操纵响应进行了仿真分析。设计的舰载直升机飞行模拟器飞行仿真系统已经成功应用到了某型舰载直升机飞行模拟器上,具有仿真度高、实时性好等特点,起到了良好的训练效果,得到了舰载直升机飞行教员和学员的认可。

An aviation simulation system of a ship carried helicopter flight simulator was researched and designed in this paper. Firstly, a model framework of the aviation simulation system was present. Secondly, the fight-hand or- thogonal axis systems used in this paper was defined. The calculating method of rotor inflow velocity, flapping angle, thrust, and torque of main rotor were discussed in detail, and the modeling method of aerodynamics of other parts of helicopter was present. Finally, the response analysis was carried out with the ship carried helicopter. The aviation simulation system was successfully applied in a helicopter simulator. The simulation results validated the biofidelity and real-time performenee, and were recognized by helicopter flight teachers and students.
