超级军网关于RDE旋转爆震发动机的大致运行原理。

有报道说md海军要用这个，就稍微查了点，分享了。
A typical RDE configuration is a ring-shaped cylinder, where fuel is fed from one end of the cylinder and a nozzle is at the other end of the cylinder. The detonation wave travels tangentially around the cylinder, burning the fuel and air as they are fed into the ring. At the other end of the chamber, the gases are expanded through the nozzle to generate thrust. This is different from a PDE, where the detonation wave travels from the front of the cylinder to the back along the long axis, while in the RDE the detonation wave travels circumferentially around the cylinder.
简单说，PDE是圆筒结构，爆炸波演轴线传播，从封闭的一头直接传向出口形成一次推力。
而RED是个双层桶，爆震波产生于内外层之间的环形空间，传播方向沿圆周方向，爆震波像侧面扩展形成了连续推力。
不知我理解对没……

再补充个更直观点的图：

有点类似转子活塞发动机？

贴一篇比较新的论文，感兴趣的可以看看。这个东西比脉冲爆震难度更大，但更有前途。目前国内就是本文作者这 ...
灰常感谢！

看起来比冲压式有前途一点................
冲压零速度启动貌似是个麻烦，与涡喷串联结构复杂 ................
要么哪个大神告诉我一下，哪个更为接近实用或者更有前景一点 {:soso_e120:}
