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.

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

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.

Fiesler Fi-103 (V1) Specifications

Engine: Argus pulse-jet
600 pounds of thrust
Length: 25' 4"
Wingspan: 17' 6"
Weight: 4800 lbs. Fully fueled
Fuel: 150 gallons of Acetylene gas
1 mile per gallon
Range: Approximately 160 miles from launch site
Performance: Speed between 360-400 mph
Flew at altitude of 2000-3000 ft
Average flight time of 22 minutes
Armament: 2337 pound war head

Not as efficient, but still an early prototype PULSE JET!!! Different
principal perhaps! Time marches on and so do design techniques.

Yes? I never disputed pulse jet. Pulse detonation has been a holy
grail for years. Pulse burn is very inefficient.

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?
