Stationary detonation combustor, and stationary detonation wave generating 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.
