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.
