GAS TURBINE ENGINE DIFFUSER COOLING AND MIXING ARRANGEMENT

摘要

A diffuser for a gas turbine engine includes a diffuser housing that has a circumferential array of hollow struts that provide a cavity. The diffuser housing includes inlet and outlet apertures that are in fluid communication with the cavity. An opening on a trailing end of the struts is in fluid communication with the cavity. The diffuser housing is configured to introduce a fluid through the inlet aperture and receive a core flow through the opening. The fluid and core flow exit through the outlet aperture.
