Gas turbine engine combustion chambers

Patent ·
OSTI ID:6536126
In a gas turbine engine having a can annular combustion system, the diffusion passage between the outlet annulus of the engine compressor and the inlets to the individual combustion chambers located in an annular housing, is partially defined by diffusion control housings, one of each of which is integral with the upstream end of a respective one of the combustion chambers. Each diffusion control housing is wedge-like in planform and increases in circumferential width and radial height in the downstream direction. An opening is provided to receive a fuel injector and an air outlet or inlets is located at the upstream end of each housing. The air inlet can be in the form of a single opening at the apex of the housing or in the form of an opening in each flank of the housing.
