研究了使用飞机发射运载火箭时的机箭分离过程。提出了一种可以解决内装式空射分离问题的整体解决方案,主要基于CAD三维实体建模方法、多体动力学方法和结合六自由度运动的计算流体力学(CFD)动网格方法。以CFD动网格计算为核心,进行了空射分离过程关键问题的研究,得到了火箭在载机气动干扰环境下的运动特性,为轨道卫星和弹道导弹的快速、廉价发射打下了研究基础。
The machine-arrow separation process when using a launch vehicle is studied. A holistic solution to the problem of in-building air-to-air separation is proposed, which is based on the CAD 3D solid modeling method, the multi-body dynamics method and the computational fluid dynamics (CFD) moving mesh method combined with six degrees of freedom motion. Taking CFD dynamic grid computing as the core, the key issues in the process of air-jet separation are studied. The kinematics of the rocket in aerodynamic interference environment is obtained, which lays the foundation for the fast and cheap launch of orbiting satellites and ballistic missiles.
