Anyone been following developments in pulse detonation engines? As a
quick primer a PDE is an engine that rather than deflagrate
(subsonic burn) it detonates (supersonic burn) the fuel /air
mixture, which provides a much higher efficiency and a larger
operating speed range.
Believe it or not, these are quite common in pyrotechnics. Here's
one I built last winter

It's the one Sharon's holding (the engine is the small tube on the
right, the payload it the large tube on the left).
Of course these are solid fuel, but give VERY impressive performance.
