空射型反舰导弹虚拟飞行建模仿真

Virtual Flight Modeling and Simulation of Air-launched Anti-ship Missile

通过对影响空气动力的参数之间的关系进行推到研究,对空气动力系数进行线性简化处理,根据某型空射反舰导弹可查到的性能参数,采用"黑箱建模"及外推的方法确定其空气动力系数,建立某反舰导弹六自由度的简化动力学模型。通过对导弹发射后的各个飞行阶段进行研究,采用航迹角度的控制方法,建立了各个飞行阶段的飞行弹道模型,实现了导弹攻击目标的全过程飞行弹道,并得到飞行航迹的仿真结果,为虚拟对抗仿真系统中水面舰艇的防空反导提供导弹攻击模型支持。

The relationship between the parameters affecting aerodynamic force was studied, and the aerodynamic coefficient was properly linearly simplified. According to the type of airborne anti-ship missile performance model, the ＂black box modeling＂ and extrapolation method was adopted to determine its aerodynamic coefficient, a typical anti-ship missile six degrees of freedom of the simplified dynamic model was established. By studying the flight phases after the missile launch, the flight trajectory model of each flight phase was established by using the control method of the track angle. The whole flight trajectory process of the missile attacking a target was realized and the simulation results of the flight path were obtained, which would provide missile attack model support for air defense and anti-missile of surface ship in virtual countermeasure simulation system.
