针对大型联合作战仿真系统需求,建立某种飞行器运动学仿真轨迹模型。讨论了射击诸元(射击方位角、俯仰程序角、初始装订参数等)的确定方法,建立了在射击平面上的飞行器主动段运动学方程组和末速修正飞行段的关机方程,推导出由平台误差分离系数到飞行器飞行主动段终点偏差的误差传递关系,然后利用椭圆轨迹理论将主动段终点偏差折算为落点偏差,并完成了轨迹数据由发射坐标系向地心大地直角坐标系的转换关系模型。仿真计算结果与飞行试验数据比对一致性好,证实了该方法的可行性。
According to the requirements of large-scale joint operation simulation system, some kind of aircraft trajectory simulation model is established. The determination methods of shooting parameters (shooting azimuth, pitch angle, initial binding parameters, etc.) Are discussed. The equations of motion of the active section of the aircraft in the shooting plane and the shutdown equations of the final velocity correction flight section are established. Then the elliptic trajectory theory is used to convert the end-point deviation of the active segment into the landing deviation, and the conversion of the trajectory data from the transmitting coordinate system to the geocentric Cartesian coordinate system is completed Relationship model. The simulation results are in good agreement with the flight test data, which proves the feasibility of this method.
