自备动力逃逸载人飞船上升段气动特性研究
Research on Aerodynamic Characteristic for Self-propulsion-escape Manned Spacecraft During Launch Phase
摘要
Abstract
Self-propulsion-escape technology is one of the important development directions for manned spacecraft,which can improve the safety during launch phase.Based on the CFD (com-putational fluid dynamic)numerical simulation,the aerodynamic characteristics of the manned spacecraft escape process during launch phase are investigated,which includes static characteris-tic,separate characteristic,and aerodynamic heating characteristic.The research results show that the safety of the separate process for the reentry module and propulsion module is impacted on the aerodynamic disturbance characteristic and the empennage has a significant impact on the stability for the manned spacecraft in the low altitude.The results can provide a reference for the conceptual design of the new manned spacecraft in China.关键词
