Department of Aerospace Engineering, K. N. Toosi University of Technology, Tehran, Iran

摘要

摘要: 提出了研究多级运载火箭级间冷、热分离的计算公式．利用Monte Carlo仿真，考虑箭体分离时，采用远离正常设计值的参数去评估分离失败的风险．分析了各种扰动，如动态不平衡，剩余推力，分离机构引起的分离扰动，以及冷、热分离未对准的影响，得到分离箭体不会发生碰撞的条件．结果表明，当前设计满足分离要求．

Abstract: The formulation used for studies of cold and hot separating stages of a multistage launch vehicle was provided. Monte Carlo simulation is employed to account for the off nominal design parameters of the bodies undergoing separation to evaluate the risk of failure for the separation event. All disturbances, effect of dynamic unbalance, residual thrust, separation disturbance which are caused by the separation mechanism and misalignment in cold and hot separation are analyzed to and out the nonoccurrence of collision between the separation bodies. The results indicate that the current design satisfies the separation requirements.
