飞机运动轨迹模拟器设计

为使用户能通过控制界面改变轨迹参数控制飞机的运动姿态,设计了飞机运动轨迹模拟器。该模拟器由轨迹模拟计算机和轨迹模拟软件组成。用户可根据飞机的运动参数及空气动力建立运动方程,给定控制规律,使飞机按照控制规律运动,即通过对飞机在每个控制时间段内的控制参数（俯仰角、偏航角、滚动角运动频率、盘旋周期、平飞高度等）的修改,控制飞机在空中飞行的姿态。在VC＋＋环境下编程并调试控制参数,得到的数据信息与理论值相符。模拟得出的数据结果表明,该模拟器能很好地模拟出飞机运动轨迹,并可通过数据接口将得到的角运动信息传递给6自由度运动模拟试验台,完成对惯性器件进行测试和飞行仿真。

Design of the Airplane Flight Track Simulator

In order to make user control the motion attitude of the airplane by changing the dates in the control interface,the author designs the flight track simulator.It includes track simulator computer and track simulator software.User can establishe motion equation based on flight motion parameters and aerodynamic.Then designs the control law,making the airplane fly according to the law.That is let the airplane act at the given pitch angle,the given yaw angle,the given roll angle motion frequency,turning cycle and the given height in every time segment.Then we debug the control parameter at the environment of VC＋＋.The dates we got is accord with the theoretical value.The result shows that this simulator can simulates the track of airplane well,and it can transfer the angular motion information to the six degree of freedom simulating test bed through data interface,completing the tests and simulate to inertial device.
