- 摘要:
- 为获得不同燃料对RBCC发动机性能影响,基于部件及发动机试验数据,建立了采用控制体法,考虑热完全气体效应、化学平衡流动效应、黏性损失及热损失等影响的发动机性能分析模型。完成模型发动机分别采用煤油、CH4、H2燃料性能仿真,获得了给定飞行剖面不同燃料对发动机推力、比冲性能的影响。在给定研究条件下,结果表明:H2推力、比冲最高,火箭引射、火箭冲压及冲压模态推力分别是煤油的1.40、1.28、1.14倍,比冲分别是煤油的1.40、1.43、2.73倍 CH4推力、比冲与煤油相当,火箭引射、火箭冲压及冲压模态推力分别是煤油的1.08、1.04、0.97倍,比冲分别是煤油的1.08、1.08、1.17倍。
- Abstract:
- In order to obtain the influence of different fuel on engine performance,based on the components and engine experimental data,an engine characteristic analysis model was established,which adopt the control body method and taked into account the effects of heat complete gas,chemical equilibrium flow,viscosity loss and heat loss. Model engine was used to complete the simulation with kerosene,methane,and hydrogen. The effects of different fuel types on the engine force and specific impulse under given ballistic were obtained as the same time. The results show that:H2 achieved maximum performance,the engine force on ejector mode,rocket ramjet mode,and ramjet mode is 1.40,1.28,1.14 times to kerosene respectively,and 1.40,1.43,2.73 times respectively for engine specific impulse methane and kerosene had similar properties,the engine force on ejector mode,rocket ramjet mode,and ramjet mode is 1.08,1.04,0.97 times as much as kerosene respectively,and 1.08,1.08,1.17 times respectively for engine specific impulse.
