- 摘要:
- 对电动泵和挤压式推进系统进行了对比研究,主要考虑了气瓶、增压气体、贮箱、电池和电机等因素对推进系统的影响,结果表明:相对于传统的挤压式推进系统,电动泵供应系统已经具有明显的优势,而且能够获得更高的综合性能;锂离子电池具有较大的能量密度和功率密度,更适合应用于电动泵供应系统;采用高性能永磁电机能够使得整个推进系统的质量更轻.在实际推进系统设计时,应综合平衡发动机推力、燃烧室压力和工作时间等参数的影响,才能有效地控制电池和电机的质量,保证整个系统具有较高的综合性能.
- Abstract:
- The comparative study on the electric pump and pressure-fed propulsion systems are performed in this paper,in which the effects of gas vessel,compressed gas,tank,battery and electric motor are considered emphatically.The results show that the electric pump system is more advanced than the traditional pressure-fed system and can achieve higher general performance,the lithium ion battery is more suitable for the electric pump system due to its higher energy density and higher power density,and the high performance permanent magnet motor cam make the electric pump-fed propulsion system lighter.In the actual design of propulsion system,only by comprehensive balance of engine thrust,chamber pressure and duration time parameters,can the researchers optimize the mass of the battery and the electric motor effectively and guarantee higher general performance of the whole system.
