Abstract: A method and apparatus for cooling the heat generated by a gas turbine engine mounted in a compartment is provided. The apparatus comprises a novel eductor (60) that incorporates a mixer nozzle (70) to entrain sufficient air flow through the compartment to provide all the necessary cooling. The engine's oil cooler (62) is mounted to the eductor so that the entrained air flow passes through it and cools the engine's oil. The novel eductor also has means for receiving a flow of high velocity air (68) from the engine and injecting this air downstream of the mixer nozzle to enhance the entraining of the cooling flow.

Abstract: An elongate exhaust gas muffler (10) for a turbine engine includes a foraminous central exhaust duct (12) which is circumscribed along its length by a plurality of tuned dissipative and reactive noise attenuation chambers (42-48). At an inlet end (16) of the muffler (10) an annular secondary flow inlet (32) is defined about the central exhaust duct and opens to the first sound attenuation chamber (42). A secondary flow of pressurized bleed air is receivable into the first attenuation chamber (42) in the muffler (10).
