小高空台高空模拟试验调试

根据航空涡桨和涡轴发动机通用规范的要求，涡轴发动机在研制过程中必须进行高空模拟试验。为此，中国燃气涡轮研究院自行设计和建成了国内首座涡轴发动机高空模拟试车台（简称小高空台）。在小高空台设备性能调试结束之后，又成功地完成了涡轴发动机高空模拟调试。涡轴发动机高空模拟试验调试不仅是对涡轴发动机高空模拟试验方法的探索，而且也是水力测功器在低温负压下的验收调试。小高空台的建成将为我国自行研制涡轴发动机提供一个必需的高空模拟试验平台。

The Altitude Simulation Test of Turboshafts in Small ASTF

Altitude simulation test must be completed during the research and deve lopment of turboshafts according to the general specification for turboshaft and turboprop. Thus, the first altitude simulation test facility for turboshafts (c alled as small ATF) was designed and set up in our country, and an altitude simu lation test with a turboshaft was completed successfully following the commissio ning of each facility. This altitude simulation test of a turboshaft is not only to explore experimental methods, but also for the acceptance of hydraulic dynam ometer under the low temperature and negative pressure. The successful completio n of small ATF will provide a necessary platform of altitude simulation test fac ility for the research and development of home-developed turboshafts.
