对水反应金属燃料和其他燃料进行了比较和分析,阐述了用于超高速鱼雷的水反应金属燃料体系。通过热力学计算,分析了水反应金属燃料的能量特性及其影响因素,并对水反应金属燃料应用于超高速鱼雷推进系统的可能途径进行了探讨。通过分析得出,水反应金属燃料充分利用雷外海水作为能源,具有显著的高能量特性,可明显提高超高速鱼雷承载燃料的能力,是超高速鱼雷的最佳能源选择;水反应金属燃料能以液态或固态形式应用于发动机,发动机形式宜采用喷射式,但环境压力对发动机比冲影响较大,其使用效率随航行深度的增加而降低。

Based on the comparison and analysis of the hydroreactive metal fuel and other fuels, the most potential hydroreactive metal fuel system used in super-cavitation torpedo are indicated. On the basis of the thermodynamic calculation, the energy characteristics of hydroreactive metal fuel and the factors affecting the characteristics are analyzed. The possible approaches of using the hydroreactive metal fuel in super-cavitation torpedo propulsion system are discussed. The results indicate that the hydroreactive metal fuel possesses outstanding high power energy characteristics and taking seawater outside torpedo as one of the power energy, and can obviously improve fuels loading capability of super-cavitation torpedo. The fuel is the best choice on power energy for super-cavitation torpedo. The hydroreactive metal fuel can be applied in jet engine in liquid or solid, but the ambient pressure influences engine specific impulse deeply, and the operation efficiency reduces with increasing the running depth.
