摘　　要：提出了1种新式带喷射泵的排气引射器设计方案。通过计算表明,在高空模拟试验台中应用带有喷射泵的引射器,可以将湿燃气中的水蒸气冷凝分离出来,减少次流流量,降低排气温度,大幅度提高燃气总压,从而提高引射系数,并可实现无污染排放。A new design concept of exhaust ejectors with jet pump was presented .The calculation results show that the water vapor of the humidity gas was separated to decrease passive flow, reduce exhaust temperature and improve gas total pressure by applying the ejector with jet pump in the high altitude simulation test stand, thereby the ejecting coefficient was improved and the non-pollution exhaust was also achieved.
