基于固体变推力发动机的火箭主动段弹道分析
The Ballistic Analysis of Rocket in Boost Phase Based on Solid Variable Thrust Motor
摘要
Abstract
In order to study the impact of variable engine thrust on rocket ballistic performance,the optimization and analysis of rocket trajectory based on variable thrust engine is carried out by using the Gaussian pseudo-spectrum method,including trajectory comparison analysis under varia-ble thrust and fixed thrust,and the influence of thrust adjustment ability on trajectory and trajec-tory comparison analysis based on variable thrust engine under different optimization objectives.The results show that if the specific impulse is unchanged and engineering constraints are not con-sidered,the thrust adjustment ability of the engine will make the trajectory of the rocket more flexible,and the speed and height coverage of the flight end will be increased,and the normal o-verload of the flight will be reduced.In addition,the greater the engine's ability to regulate thrust,the more adaptable a rocket's active segment trajectory is.关键词
