论文摘要
为了阐明旋转爆炸推进系统的总压力增益性能，提出了扩展的Hugoniot曲线，并针对具有可变横截面区域（SFSVA）的稳定流量系统进行了讨论。发现沿系统墙的无量纲压力积分（θ）对给定入口MACH数（M0）和热量释放（Q）具有对SFSVA的压力增益的关键影响。获得SFSVA的正压增益的关键是达到匹配的θ，M0和Q。
For the clarification of total pressure gain performance of rotating detonation propulsion systems, the extended Hugoniot curve is proposed and discussed for the stable flow systems with variable cross-section area (SFSVA). The dimensionless pressure integral (θ) along the system walls is found to have critical impact on the pressure gain of the SFSVA with given inlet Mach number (M0) and heat release (q). The key to obtain positive pressure gain of a SFSVA is to achieve the matching θ, M0 and q.
