What is a Pulse Detonation Engine?
One of the newest and most exciting areas of pulse-jet development is the
Pulse Detonation Engine (PDE). While they work on similar principles to a
regular pulsejet, the PDE has one very fundamental difference -- it detonates
the air/fuel mixture rather than just allowing it to simply deflagrate (burn
vigorously).
