摘　　要：在水反应金属燃料发动机性能分析研究基础上,分析了壅塞式和非壅塞式发动机构型优缺点及性能调节特性,着重探讨了非壅塞式水反应金属燃料发动机燃气流量自适应调节规律和特点。计算结果分析表明,非壅塞式发动机具有水燃比自适应调节特性,且高压强指数水反应金属燃料调节效果显著。Based on performance analysis of hydroreactive metal fuel motor, advantages and disadvantages of choked and unchoked hydroreactive metal fuel motor configuration as well as performance adjustment characteristics were analyzed. Self-adaption adjustment laws and characteristics of gas consumption for unchoked hydroreactive metal fuel motor were discussed emphatically. The calculation results show that water/fuel ratio of unchoked motor possesses self-adaption adjustment characteristics, and adjustment effect of hydroreactive metal fuel with high-pressure exponent is remarkable.
