摘要

摘要: 为适应无人水下航行器(UUV)长航时、远航程、大航深等应用需求, 提出了一种以Li/SF₆为能源的新型UUV热电联合动力系统构型方案。该系统采用朗肯循环, 燃料能量密度可达600 Wh/kg, 是现有电池的3倍。文中建立了工质参数对系统性能影响规律的求解算法, 分析了蒸发器出口温度、压力和冷凝器压力对系统性能的影响。结果表明: 在研究范围内, 蒸发器出口温度每增加100 K系统效率增加0.8%; 蒸发器压力每增加1 MPa系统效率增加0.5%; 冷凝器压力每降低0.01 MPa系统效率增加0.2%。该方案可为现有UUV供能不足提供新的解决途径, 文中所做研究结论可为UUV动力系统设计提供参考。

Abstract: To develop an unmanned undersea vehicle(UUV) with the performances of long endurance, long range and deep depth, a new thermoelectric power system using Li/SF₆ as energy is proposed. The system adopts Rankine cycle, and its fuel’s energy density can reach 600 Wh/kg, which is three times higher than that of the current battery. The solution algorithm for the working medium parameters’ effects on the system performance is established, and then the influences of evaporator outlet temperature, pressure, and condenser pressure on the system performance are analyzed. The results show that, within the scope of certain parameters, 0.8% increase in the system efficiency is gained for every 100 K increase in the evaporator outlet temperature; the system efficiency rises by 0.5% for every 1 MPa increase in the evaporator pressure; and the system efficiency rises by 0.2% for every 0.01 MPa decrease in the condenser pressure. This system gives a new solution to enhancing UUV energy supply, and the obtained conclusions may provide a reference for the power system design of an UUV.
