摘　　要：为提高高超声速风洞的运行效率,满足新形势下的试验需求,对真空保障系统进行了改造。改造后,真空系统运行维护成本降低,操作环境改善,风洞试验效率显著提升。本文介绍了真空保障系统改造方案,对系统改造前后进行了性能对比。The vacuum system has been, reformed in order to improve testing efficiency of hypersonic wind tunnel to adapt to the new situation. After this reformation, the running and maintenance cost of vacuum system falls; the operating conditions are improved and the testing efficiency of wind tunnel is upgraded significantly. This paper presents the reform scheme of vacuum system and contrasts the new abilities with the former.
