Examples
- In this thesis , based on pershing ii surface to surface missile , a new kind of ballistic missile was designed with an additional rocket engine , which can be ignited twice . firstly , aerodynamic computational models of missile body and warhead which reentry with supersonic are built according to the task requirements ; secondly , the propulsion system model of missile is built whose first two stages are solid rocket engines and the third stage is liquid - solid combined rocket engine . the nozzle and the shape of the engine are designed to meet the needs of the populsion project ; thirdly , the trajectory model of the mass point is built and a wavy trajectory is designed & optimized ; finally , the ability of a missile ' s breaking through defence is analyzed
以美国潘兴导弹为原型，增加可两次点火的末级发动机，改装成具有跳跃能力的地地弹道导弹；首先，根据任务需求，建立了导弹的气动模型，并建立了弹头再入时高超声速气动模型；其次，建立了导弹推进系统模型，前两级采用了固体火箭发动机，第三级采用了固?液组合火箭发动机，并在总体方案要求下，对发动机喷管和外形进行了设计；第三部分，建立了导弹质点弹道模型，设计了一条跳跃式弹道，并对跳跃式弹道进行了优化设计；最后，对导弹进行了突防能力分析，从分析的结果可以看出，跳跃式弹道的突防能力比常规的抛物线弹道要强。
