| 摘要: |
| 基于水与金属燃料反应的水冲压发动机是一种新型的水下动力装置。为了研究水下冲压发动机的基本性能,在简述热力计算原理的基础上,以含铝贫氧推进剂为例对燃气发生器式水冲压发动机、以铝金属燃料为例对漩流式水冲压发动机进行了不同工作状态下的热力计算,得出了发动机比冲与水燃比、工作压强等之间的定性关系。 |

| Abstract: |
| The water ramjet based on the reaction of water and fuel is a new kind of underwater engine.To investigate the performance of the engine,based on thermodynamic calculation.Furthermore,thermodynamic calculation for the water ramjet,which uses fuel-rich propellant containing aluminum or uses aluminum powder,under different conditions is carried out as an example.The qualitative relationship of specific impulse versus water/fuel,pressure of combustion chamber is obtained. |
| Key words: Water ramjet~+ Metal/water reaction fuel~+ Thermodynamic calculation Performance |
