The aerodynamic method of decreasing the A-weighted sound pressure level in the gas turbine

摘要

In the gas turbine & the engine, attenuation and pressure fluctuation of the combuster, method and the device which are divided from attenuation and pressure fluctuation of the turbine. The said engine has the compressor, the combuster and the turbine, makes the thermal gases style to the said turbine cause from the said combuster. Aerodynamic trip at least either of the inside shrouds of the combuster wall, and the nozzle guide vane ring is provided in one, at the same time, in order to in the thermal gases style from the combuster, to discharge the compressed air jet from the kurosuhuro port, is provided. The air jet from the said kurosuhuro port, although attenuation and pressure fluctuation are divided between the combuster and the turbine, adding, making turbulence increase, makes temperature distribution equalize.
