| 摘 要： | 为了在直升机飞行模拟器上实现虚拟驾驶,建立了六自由度的直升机动力学模型。该模型以拉格朗日方程为基础,以实时获取的驾驶杆状态信息为输入,对直升机受力进行了简化分析。采用龙格库塔法进行动力学模型的实时解算。最后通过与实际试飞数据比较以及仿真画面,验证了此动力学模型和仿真算法具有较高的可靠性,能更精确地对直升机机动飞行科目进行预先性研究。

| Abstract: | In order to achieve the aim of virtually piloting on flight simulator,6-DOF dynamics model of helicopter was established.Based on Lagrange equation,taking the real-timely acquired state information from joystick as the input,a simplified analytical model for the force on helicopter was proposed.Adopting Runge-Kutta iterative arithmetic,the dynamics equation was solved in real time.Finally,the higher reliability of the model and simulation algorithm was verified through comparing with actual flight data and simulation scene,so it can be seen as a more accurate research in advance for helicopter maneuver flight subject. |
