Pulse Detonation Engines (PDE's)

How much potential do PDE's have? Will they ever be more than a laboratory
curiousity?

Wasn't the German V1 buzz bomb powered by a PDE pulse jet? Perhaps a
crude one but still a pulse detonation engine of sorts.

Yes.

Nope. Pulse-burn. Much less efficient.

Symantics! It was a pulse jet! Bomarc SAM was a Ram jet and operated
on a different principal but was quite effective as a propulsion system
after getting up to speed by solid booster on the B-model.

Nope. And what's a ramjet got to do with anything?
Another clumsy hoopster.

That's where the "buzz" came from! 8-)

If this PDE research pans out, what would such an engine be used on?

A high-speed, high-altitude cruise missile (Something like FastHawk or
ARRMD)?

An SR-71 replacement (possibly manned, but probably not)?

The first stage of a two stage reusuable space launch system?

Something else?

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.
