Steady detonation combustor and steady detonation wave generation method

摘要

A steady-state detonation combustor and a steady-state detonation wave generating method, in which a stabilized detonation wave can be generated by generating a hypersonic and unburned premixed gas. An rich premixed gas whose gas fuel is rich is combusted in a rich premixed gas combustion chamber ( 11 ) to generate a fist high-temperature and high-pressure burned gas, while at the same time, a lean premixed gas whose oxygen is rich is combusted in a lean premixed gas combustion chamber ( 12 ) to generate a second high-temperature and high-pressure burned gas, and subsequently, after each high-temperature and high-pressure burned gas is accelerated to hypersonic speed and at the same time mixed together through an interpenetrating nozzle ( 40 ), a premixed gas obtained by the mixture and containing the gas fuel and the oxygen which are unreacted is impinged on a steady-state detonation stabilizer ( 60 ), so that a stabilized detonation wave is generated.
