摘要
Abstract
Injection tube system of water ramjet was researched in this paper. A two level water injection tube system was modeled and the pressure loss equations were given. Based on the thermodynamic calculation method, optimal water-fuel ratios of magnesium and aluminium based fuel were obtained. Water specific impulse was proposed for convenient estimation of the water flow required by the motor which shows that the injected water is mainly proportional to the design thrust rather than the fuel type. The pressure loss of the tube system was mostly caused by the diffluent tube and the local parts. Designing principle was established for better understanding of the water injection system. In order to achieve less pressure loss, the tube size of the system should be enlarged as more as possible.关键词
