SYSTEM AND METHOD FOR CONTROLLING COMBUSTION DYNAMICS BY ACOUSTIC LIMITATION / SUPPRESSION OF FLOW FLUCTUATION OF FUEL AT FUEL INJECTION LOCATION

摘要

A combustion dynamics control system for a gas turbine engine for aeronautics or for a floor installation, employing an acoustic control (50) designed to substantially reduce to zero pressure disturbances in an orifice (52) of premix fuel injection in response to a control signal such that fuel flow disturbances in the fuel injection port (52) are substantially zero.
