ABSTRACT:
A variable volume combustion chamber for a gas turbine engine that has a able wall to vary the volume of the combustion chamber. The movable wall is positioned according to the operating conditions of the gas turbine engine, achieving one extreme position under idle power and another extreme position under full power. The movement of the wall between the two extreme positions maximizes the efficiency of the combustion chamber for operating conditions between idle and full power. The combustion chamber also restricts at least a portion of the oxidizer intake when the movable wall is positioned for idle power conditions and opens the oxidizer intake when the wall is positioned for maximum power conditions to maximize the flow of oxidizer into the combustion chamber.
