Abstract: A pulse detonation combustor including a plurality of nozzles engaged with one another via mating surfaces to support a gas discharge annulus in a circumferential direction. The pulse detonation combustor also incluidng multiple pulse detonation tubes extending for the nozzles and a plurality of thermal expansion control joints coupled to the plurality of pulse detonation tubes. Each of the plurality of thermal expansion control joints is configured to facilitate independent thermal growth of each of the pluratly of pulse detonation tubes. The thermal expansion control joints may be configured as a bellows expansion joint or a sliding expansion joint.

Abstract: An engine (100) contains a compressor stage (101), a pulse detonation combustion stage (105) and a turbine stage (103). The pulse detonation combustion stage contains at least one pulse detonation combustor (109) which has an inlet portion (111). The pulse detonation combustor is oriented longitudinally and/or tangentially with respect to a centerline of the engine. A plenum (115), a casing (107), a diffuser (119) and a shroud (113) can be added in this combustion stage to achieve better performances.
