Mathematical Description and Simulation of Helicopter Maneuver Flight

直升机机动飞行的研究对于直升机空战战术具有十分重要的作用,为此首先介绍了直升机机动飞行的数学描述及仿真方法,即在直升机三自由度模型下用数学方法对直升机机动飞行轨迹进行描述,得出完成机动动作需要施加在直升机上的控制指令,通过指令转换模型将控制指令转换为操纵直升机的操纵量,然后在直升机飞行动力学模型下对机动飞行进行仿真。然后分别对直升机"加速减速"机动和"障碍滑雪"机动科目进行了数学描述和机动飞行仿真,仿真结果验证了数学描述及仿真方法的可行性。

The research of helicopter maneuver flight plays a very important role for helicopter air combat tactical. Firstly, this paper introduced the mathematical description and simulation method of helicopter maneuver flight, in the 3 DOF（ degree of freedom）helicopter model use mathematical method to describe the helicopter maneuver flight path, get the helicopter control command that needed to complete maneuver flight, through the command transformation model the control command was converted to the control values for the helicopter manipulation, and then do the simulation of helicopter maneuver flight in the helicopter flight Flight dynamics model. Then, completed the mathematical description and simulation of ＇ acceleration and deceleration＇ and ＇ slalom＇ maneuver respectively, and the simulation results show that the methods of the mathematical description and simulation is feasible.
