Active control of acoustic instability in combustion chambers

Active control of acoustic instability in combustion chambers

A combustion chamber subject to the build-up of acoustic vibrations may have the vibrations inhibited by an electrode system which can be modulated to produce anti-noise. Sound is sensed by a microphone which may be mounted remotely to produce a control signal coupled to a voltage generator feeding...
