    摘要： A detonation device cleaning system includes a vessel having a main body including an outer surface and an inner surface that collectively define an interior chamber. A detonation combustor cleaning device is mounted to the vessel. The detonation combustor cleaning device includes at least one combustion chamber that defines a combustion flow path. The at least one combustion chamber includes a deflection member arranged along the combustion flow path. An ignition device is operatively connected to the at least one combustion chamber. The ignition device is selectively activated to ignite fuel within the at least one combustion chamber to produce a shockwave that moves in a first direction along the combustion flow path, is redirected back along the flow path within the at least one combustion chamber, and passes into the interior chamber to dislodge particles clinging to the inner surface of the vessel.

    摘要： A ground based power generation system contains at least two compressor stages, a combustion stage and a turbine stage. An intercooler is positioned between the two compressor stages and a regenerator is positioned between the compressor stages and the combustion stage. The combustion stage contains at least one of a pulse detonation combustor and constant volume combustor. Downstream of the combustion stage is the turbine stage. Heat for the regenerator is supplied from the turbine stage. Further, a bypass flow device is included which re-directs flow upstream of the combustion stage to downstream of the combustion stage and upstream of the turbine stage.

The supersonic propulsion system includes a plurality of systems for efficiently creating cyclic detonations and at least one rocket booster device. Each of the systems include at least a first initiator chamber configured to generate an initial wave, at least one main chamber coupled to the first initiator chamber. The main chamber is configured to generate a main wave and to output products of supersonic combustion. The products are generated within the main chamber.
