摘　　要：在给定的航空发动机排气条件下 ,对高空台排气系统中抽气机抽气和引射器引气这两种设计方案的投资和运行能耗进行了对比和简要的分析。在设计模拟航空发动机排气环境的试验设备时 ,应优先选用抽气机抽气的方案 ,充分利用其技术上成熟、难度小、风险小。Comparison and preliminary analysis are made between two design schemes of pumping with exhaust blower and injecting with injector for the investment and energy consumption in operation at given engine exhaust conditions. In design of aero engine exhaust environment simulation facilities, it is suggested to use the scheme of pumping with exhaust blower in priority, as it is technically matured with minor difficulties and risks, also investment wise.
