How does this differ from the pulse engines
that powered the V1's, one of which nearly
de-parted me off from the happiest days of
my life (allegedly)?

Good observation. From:
http://en.wikipedia.org/wiki/Pulse_detonation_engine
"The main difference between a PDE and traditional pulsejet is the way
in which the airflow and combustion in the engine is controlled. In the
PDE the combustion process is supersonic, effectively an explosion
instead of burning, and the shock wave of the combustion front inside
the fuel serves the purpose of the shutters of a pulsejet. When the
shock wave reaches the rear of the engine and exits the combustion
products are ejected in "one go", the pressure inside the engine
suddenly drops, and air is pulled in the front of the engine to start
the next cycle. Some designs require valves to make this process work
properly."
Of course the V2, being a ballistic weapon, eliminated the anxiety of
hearing the pulsejet approach. I doubt you even knew it was coming.
