| 摘 要： | 在完全充填脉冲爆震发动机的Ficket-Jacobs热力循环的基础上,提出了用于分析部分充填下脉冲爆震发动机的热力循环性能的分析方法.结果表明,部分充填的工作方式会降低发动机总的热力循环效率,当爆震燃烧用于功率输出时,这种工作形式是应该避免的;但另一方面,由于部分充填的工作方式使爆震燃烧释放的能量在燃烧产物和隔离气体间重新分配,这种工作形式可以提高脉冲爆震发动机的总效率.

| Abstract: | Ideal partially-fueled detonation cycle model was established based on FicketJacobs cycle.It is shown that partial fuel filling will cause decrease of total thermal efficiency,which means that this work mode is not adequate to the application of detonation for power output.However,as energy exchange between combustion products and purge gas occurs during the expansion of the detonation products under this mode,it can be used to enhance the propulsive efficiency of PDE. |
