Abstract
The effectiveness of a radial inlet air swirler for the fuel nozzle in the combustor of a gas turbine engine is enhanced by reducing the pressure loss associated with compressor discharge air as it enters the combustor cowl. A circumferential uniform feed pressure is created by an aerodynamically contoured projection on the pressure plate supporting the fuel nozzle and a cooperating dynamic swirler scoop at the inlet of the swirler. The increased flow and fuel/air mixing reduces smoke production without adversely affecting combustor or engine performance.
