| 摘 要： | 针对多级固体运载火箭小型化需求,采用整体级概念(ISC)进行总体方案改造和优化设计.描述了2种ISC概念的特点,以某三级常规方案固体运载火箭为基准,通过利用级间的剩余空间,完成ISC方案改造.建立了运载火箭的整体级发动机动力计算模型、气动计算模型和弹道计算模型,并结合任务指标要求,提出了运载火箭的总体参数优化模型.在相同的任务条件下,完成了常规方案和2种ISC方案的优化.结果表明,引入ISC概念可将运载火箭体积缩小15%～20%,起飞总重缩小1%～1.5%,满足了总体指标要求,达到了运载火箭小型化设计目的.

| Abstract: | For the purpose of decreasing the volume of multi-stage solid launch vehicle,Integrated Stage Concept(ISC) was introduced to improve performance of the launch vehicle.Two kinds of ISC scheme characteristics were described.Taking a traditional three-stage solid launch rocket as example,ISC scheme was used for inter-stage residual space modification of the rocket.The dynamic calculation model,aerodynamic calculation model and ballistic calculation model for integrate stage launch rocket motor were derived res... |
