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 including 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 plurality of pulse detonation tubes. The thermal expansion control joints may be configured as a bellows expansion joint or a sliding expansion joint.

A pulse detonation combustor, comprising:
- a plurality of nozzles configured to support a gas discharge annulus in a circumferential direction;
- a plurality of pulse detonation tubes extending to the plurality of nozzles;
- and
- a plurality of thermal expansion control joints configured to facilitate independent thermal growth of each pulse detonation tube,
- wherein each of the plurality of thermal expansion control joints is formed integral with a pulse detonation combustor casing circumscribing the pulse detonation tube and provides for axial expansion of the pulse detonation casing, and
- wherein the pulse detonation tube further includes at least one alignment fm on an exterior surface providing concentric alignment of the pulse detonation tube relative to the pulse detonation combustor casing.
A pulse detonation combustor, comprising:
- a plurality of nozzles each having a nozzle exit orifice and a nozzle inlet, wherein the plurality of nozzle exit orifices are configured to form a gas discharge annulus;
- a plurality of pulse detonation tubes each coupled to a respective nozzle inlet;
- and
- a plurality of thermal expansion control joints configured to facilitate independent thermal growth of each pulse detonation tube,
- wherein each of the plurality of thermal expansion control joints is configured integral with a pulse detonation combustor casing circumscribing the pulse detonation tube and provides for axial expansion of the pulse detonation casing, and
- wherein the pulse detonation tube further includes at least one alignment fm on an exterior surface providing alignment of the pulse detonation tube relative to the pulse detonation combustor casing.
