涡轮排气液化循环发动机的能量分析

Energy Analysis of the Turbine Exhaust Liquefaction Cycle Engine

对涡轮排气液化循环发动机液化水的处置进行了研究。通过热力学分析获得了发动机性能的理论解,并利用热力计算进行验证。分析表明液态水直接排出发动机将导致约2%的比冲损失。分析了发动机各环节的能量传递,获得了燃烧室中心燃烧区焓增的理论表达式,可作为燃烧室性能的详细分析的基础。

The treatment of the liquid water of the turbine exhaust liquefaction cycle engine （TELCE） was studied in this paper. The theory solution was acquired by thermal analysis and was identified by thermal calculation. The analysis showed that there was about 2% specific impulse loss if liquid water was drilled out of engine directly. Further more, the energy transfer in TELCE was analyzed, and the enthalpy theory expression of the gas in engine center combustion region was given out, which could be as the detail analysis base for the chamber performance.
