摘要
介绍了某动力装置采用空气/煤油燃气发生器的研究情况。为了实现某动力装置的燃料无毒化,研制了空气/煤油燃气发生器,并完成与涡轮的联动试验,试验结果表明燃气发生器性能满足动力装置要求。该燃气发生器采用电火花点火,具备富燃(余氧系数α<0.3)和富氧(余氧系数α>4.5)双模式工作能力,两种模式下均实现了轴功率输出。此外,燃气发生器还能在两模式间连续切换,且不熄火。这为满足功率需求提供了第三种工作模式。该模式也实现了轴功率输出。
An emergency power unit(EPU) with air/jet fuel gas generator is studied in this paper.The air/jet fuel gas generator for EPU was developed to meet the requirement of EPU with non-toxic propellants.The operation test of linkage to turbine was successfully passed.Test results show that the performance of the generator meet the requirements of EPU.The spark ignition is adopted in the gas generator which can operate either in a fuel-rich mode(α<0.3),or an oxidizer-rich(α>4.5) mode.Both of two modes realized shaft power output.In addition,there is the third mode that the gas generator also can switch between the two modes without flameout.The mode had achieved the shaft power output.
