Optimization Design Of Solid Rocket Motor And Intercept Algorithm Analysis For Direct-Ascend Anti-Satellite Missile

The main work of this thesis is about the optimization design of the solid rocket motor (SRM) and the intercept algorithm of an air-launched direct-ascend anti-satellite missile. Adopting the optimization rules applied to SRM, design variables and constraints are determined from the computational model of the mass and the performance for the SRM, then the optimization model of the SRM of ASAT(anti-satellite missile) is built. With Exterior Penalty Function method, optimization results are derived from different initial values. Ballistic trajectories are integrated accoding to the missile's optimized overall parameters. The resuts show that the anti-satellite capability of the optimized missile is better than F15 ASAT.The intercept algorithm of ASAT is discussed on the basis of the optimization of the SRM. The mathematical model of the intercept problem is derived from the spacial ballistic trajectory computational model and the orbit prediction model. The interception simulation results show the Newton iteration algorithm is feasible to this kind of problem. After analyzing the influence of 5 initial launch parameters to the intercept height and velocity, the interception capability of the missile is estimated.Some useful conclusions are given in the last section, followed by analyses of the possible future work.
