摘要

The method involves carburizing a combustion air supplying system with an axial conduit and a spin part (6) inducing component azimuth speed at air flow. The axial conduit is emerged out from a bottom wall (2) of an annular combustion chamber (21). The spin part is arranged at distance (L) of the bottom wall of the chamber. The distance of the bottom wall is adjusted to create phase difference between an acoustic wave and an aerodynamic oscillation generated through the spin part by the acoustic wave. An independent claim is also included for a combustion chamber of a gas turbine engine, comprising a basic wall.
