Abstract
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 casing, is partially defined diffusion control housings, one of each of which is located adjacent the upstream end of the respective combustion chamber. Each control housing is wedge-like in planform and has a downstream recess to accommodate the dome-shaped head of the combustion chamber. The control housing increases in circumferential width and radial height in the downstream direction to reduce the diffuser area ratio. Scoops can be provided to guide primary and dilution air into each combustion chamber.
