I think its theoretically possible, unless you're talking about at atmospheric pressure. Its a holy grail of engine building to create supersonic explosions to drive the engine. It would create a massive boost in efficiency. http://en.wikipedia.org/wiki/Pulse_detonation_engine

At atmospheric pressure its going to deflagrate, at much higher pressures you can get a sonic detonation (this is what happens in your standard internal combustion engine. Super sonic is possible but damn hard to achieve. We're still working on it.
