Pulse Detonation Engines (PDE's)

There are significant problems to using PDEs as a propulsive source.
The magnitude of the shockwaves produced is extremely high as are the
levels of vibration.

A craft using such a power-plant will need some very special attention
paid to the acoustic and physical isolation of the engine.


Hmmm

The British edition of scrap heap challenge recently had a program
in which teams had to build a jet propelled car.

The winner built a pulse jet and the 'high tech' isolation of engine
from vehicle seemed to consist of welding the bugger to the frame
though there was lots of duct tape in view

Fact is almost every motor car on the road runs with a
pulse detonation engine, its just that the pulse drives
a piston rather than being used for jet effect.
