离散相似法在空-空导弹数字仿真中的应用
Application of discrete similar method to the digital simulation for air-to-air missiles
摘要
Abstract
To obtain the real-time calculation of attack area for air-to-air missile, a new method for fast simulation was presen-ted. The six degree of freedom simulation model was simplified effectually. Based on the instantaneous equilibrium assumption, the centroid equations of motion was established. The discrete model was built by using the time discrete similar method. Through com-puter simulation to compare the traditional model, variable step integration model, aerodynamic coefficients fitting model and dis-crete model simulation,results show that the aerodynamic coefficients fitting model provides the fastest but least accurate simulation. Compared to the traditional model,the discrete model can greatly increase the simulation velocity with high precision,which may present a feasible project for rapid resolving of attack area of air-to-air missile.关键词
