ABSTRACT:
A method for operating a combustion chamber 12 for a gas turbine engine is disclosed. Various details of the method are developed which improve the ability of the combustion chamber 12 to avoid blow-outs of the combustion chamber. In one particular embodiment, the method employs a fuel distribution valve 12 having ports which provide equal flows through equal flow areas at high power, high aircraft Mach number (such as, greater than 0.8 M) operation while providing unequal flows through unequal flow areas at certain preselected low power operative conditions of the engine which follow the high power operative condition.
