Abstract
The gas turbine combustor air swirler includes a spring temper swirler member having a plurality of air control doors or vanes so cut therein about the longitudinal axis of the combustor inlet as to be integrally and resiliently pivotally connected to the swirler member. The air control doors are progressively canted open to provide predetermined air flow rate and air swirl angle to the combustor inlet in response to increases in air pressure differential thereacross resulting from progressive increases in fuel flow through the nozzle during various regimes of engine operation. The swirler is free of linkages and sliding or other contacting components that are susceptible to binding and other malfunctions in service in the engine.
