Patent ID: 7310951

Claim:
A steady-state detonation combustor to combust a premixed gas containing a gas fuel and oxygen by generating a detonation wave in steady state with respect to a static system, said steady-state detonation combustor comprising: a rich premixed gas combustion chamber to combust a detonative rich premixed gas in which the gas fuel is in a rich state with respect to the oxygen; a lean premixed gas combustion chamber to combust a detonative lean premixed gas in which the gas fuel is in a lean state with respect to the oxygen; an interpenetrating nozzle including a plurality of nozzles arranged in an interpenetrating manner, in which a first high-temperature and high-pressure burned gas containing the gas fuel which is unrecated obtained by combusting the rich premixed gas in said rich premixed gas combustion chamber, and a second high-temperature and high-pressure burned gas containing the oxygen which is unreacted obtained by combusting said lean premixed gas in said lean premixed gas combustion chamber, are respectively accelerated to hypersonic speed, such that their static temperatures descend and at the same time they are mixed together; and a steady-state detonation stabilizer arranged at a position which bars a flow of a premixed gas containing the unreacted gas fuel and the unreacted oxygen obtained by mixing the first high-temperature and high-pressure burned gas and the second high-temperature and high-pressure burned gas through said interpenetrating nozzle, in which the premixed gas is combusted by generating, through impingement of the premixed gas flowing at hypersonic speed through the interpenetrating nozzle, the detonation wave which is stabilized.
