内置式空中发射运载火箭发射方向研究

Research on the Launch Direction of Internally Carried Air-Launched Vehicle

对运载器与载机分离过程的几个阶段采用统一模型进行研究,建立了分离过程物伞系统的刚体-质点模型。以此数学模型为基础,对空中发射的分离过程用Matlab/Simulink进行了仿真计算。结果表明,前向发射在分离过程结束时运载器的高度损失和速度损失比后向发射小,性能优于后向发射,对实际工程应用具有重要参考价值。

For the air-separation process of air-launch vehicle from the carrier aircraft, this paper gives out the unified model that is the rigid body-mass point model of the body-parachute system. The body-parachute system is composed of launch vehicle and stabilization parachute. The air-separation process includes the separation of the body-parachute system from the carrier aircraft and the separation between the launch vehicle and the stabilization parachute. The whole separation is simulated in Matlab/Simulink. The analyses of simulation results demonstrate that the height loss and speed loss of the launch vehicle in forward facing launch are smaller than in aft facing launch after the air-separation process finished. The performance of forward facing launch is better than that of aft facing launch, which has very important value in engineering practice.
