Abstract
In one embodiment, a pulse detonation system includes a pulse detonation tube including a base tube and a thermally protective layer disposed adjacent to an inner surface of the base tube. The thermally protective layer is configured to limit temperature fluctuations at the inner surface of the base tube to less than approximately 20 degrees Celsius during operation of the pulse detonation system, and the thermally protective layer does not comprise a ceramic coating.
Claims20
A pulse detonation system, comprising:
- a pulse detonation tube comprising a base tube and a thermally protective layer disposed adjacent to an inner surface of the base tube, wherein the thermally protective layer is configured to limit temperature fluctuations at the inner surface of the base tube to less than approximately 20 degrees Celsius during operation of the pulse detonation system, and wherein the thermally protective layer does not comprise a ceramic coating.
A pulse detonation system, comprising:
- a pulse detonation tube configured to resist a pressure associated with a detonation reaction;
- a nozzle coupled to a downstream end of the pulse detonation tube and configured to receive a flow of exhaust gas from the pulse detonation tube;
- and
- a thermally protective layer disposed adjacent to an inner surface of the pulse detonation tube, to an inner surface of the nozzle, or a combination thereof, wherein the thermally protective layer is configured to limit temperature fluctuations at the inner surface of the pulse detonation tube, at the inner surface of the nozzle, or a combination thereof, to less than approximately 20 degrees Celsius during operation of the pulse detonation system, and wherein the thermally protective layer of the pulse detonation tube, if present, does not comprise a ceramic coating.

A pulse detonation system, comprising:
- a pulse detonation tube;
- a nozzle coupled to a downstream end of the pulse detonation tube;
- and
- a turbine coupled to a downstream end of the nozzle and configured to receive a flow of exhaust gas from the pulse detonation tube via the nozzle;
- wherein at least one of the nozzle or at least one component of the turbine comprises a base material and a thermally protective layer disposed adjacent to a surface of the base material facing the flow of exhaust gas, wherein the thermally protective layer is configured to limit temperature fluctuations at the surface of the base material facing the flow of exhaust gas to less than approximately 20 degrees Celsius during operation of the pulse detonation system.
