Abstract
A cooling manifold of a diffuser baffle of a compressor section of a gas turbine engine of an aircraft is provided. The cooling manifold includes an interior body and an exterior body. The interior body includes an interior body surface and an elongate, solid body extending from the interior body surface and defining one or more through-vias. The exterior body is configured to surround the interior body to form a cavity, which is fluidly communicative with the one or more through-vias, between the exterior body and the interior body. The exterior body defines one or more apertures by which the cavity is receptive of coolant such that the coolant is distributed throughout the cavity and exhausted tangentially through each of the one or more through-vias.
