    摘要: A generally annular combustion chamber for a gas turbine engine is disclosed having fuel injector assemblies, each with an oxidizer swirler, extending through an upstream end wall of the combustion chamber and control means connected to the control diaphragms of the oxidizer swirlers in order to move the control diaphragms between maximum and minimum flow positions. The upstream end wall of the combustion chamber defines complementary oxidizer intake orifices which have movable closure plates to selectively open or close the complementary oxidizer intake orifices. A mechanical linkage connects the closure plates to the control diaphragm of an adjacent air swirler such that, when the control diaphragms are in their maximum flow positions, the closure plates close the complementary oxidizer intake orifices, and when the control diaphragms are in their minimum flow positions, the closure plates are moved such that the complementary oxidizer intake orifices are fully open.

    摘要: A combustion chamber structure wherein the combustion chamber extends around a central, longitudinal axis and has primary oxidizer intake passageways whose positions along the central axis relative to an end of the combustion chamber are adjustable depending upon the operating conditions of the gas turbine engine. By controlling axial positions of the primary oxidizer intake passageways, the dwell time of the combustion gases and primary oxidizer inside the combustion zone of the chamber may also be controlled so as to increase the stability of the combustion, while at the same time minimizing the polluting emissions. The invention also encompasses the concept of adjusting the cross-sectional area of the primary oxidizer intake passageways as their positions along the central axis are adjusted. This enables a more accurate control of the volume of the primary oxidizer flow in addition to controlling the location of the flow.
