Sort of in the same vein, here's a PNAS report [1] of a continuous combustion detonation engine. No circulating detonation wave, no pulses, just steady combustion in a propellant stream fast enough to stabilize the detonation region at a feature in the engine. Just speculation on my part, but I would think the Isp would be higher than the usual chemical combustion regimes due to higher temperature in the detonation volume. Pretty interesting stuff.
