摘　　要：热发射的高温高速燃气射流对发射平台产生冲击,导流器应同时适应结构强度和高温高压的燃气冲击,导流器的型面优化设计可降低射流引起的烧蚀和冲击。本文通过数值仿真模拟方法,研究了3种导流器方案,分别计算了每种导流器型面方案下燃气射流的流场,选出了最优方案,提高了发射的安全可靠稳定性。High temperature and high speed combustion gas jet of hot launch can lead to high impact on the launch platform. In this case, it is required that the hot launch deflector need be able to bear the impact of the high temperature and high pressure combustion gas. The optimization design of the deflector profile can decrease the ablation and impact by the gas jet. Through numerical simulation, this work developed three different deflector models and simulated the combustion gas flow field of each deflector profile to determine the optimal model, so as to improve security and stability of the launch.
