Patent abstract
A method for decreasing combustor acoustics in gas turbine engines is provided. The method includes fabricating a plurality of premixers, chamfering a trailing edge of a main swirler shroud of each premixer, coupling a respective one of the chamfered premixers to each of a plurality of combustor domes, and coupling the plurality of combustor domes to an inlet of a combustor in a circumferential arrangement such that, during operation, the chamfered edge facilitates reducing combustor acoustics.
