摘要

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 respectively. In combination of design index requirements, system parameter optimization model was put forward. Under the given task conditions, the traditional scheme and two kinds of the ISC scheme were optimized respectively. The results show that the volume of multi-stage solid launch vehicle can be decreased by 15%-20% by using ISC concept, and the takeoff mass can be decreased by 1%-1.5%, which can meet system index demands and miniaturized requirements.
