ABSTRACT:
A combustor for a gas turbine engine has a prevaporization chamber wall having a plurality of air passages therethrough and wherein a variable geometry air flow control element is located in overlying relationship with the air passages to control air flow therethrough. A fuel injector is located concentrically within the chamber for supplying fuel for combustion with air supplied thereto and a hydraulic control actuator is located in surrounding relationship with the injector immediately outboard of the chamber including the hydraulic actuator having pressure supplied thereto from the fuel flow through the nozzle and including means for coupling the actuator directly to the control element for increasing primary air flow in accordance with increased fuel flow to the prevaporization chamber.
