An exhaust device for a compressor bypass bleed system of a ducted fan engine includes a housing having an inlet end and an outlet end and defining a centerline axis from the inlet end to the outlet end, an inlet flow conditioner arranged at the inlet end, the inlet flow conditioner including a plurality of inlet openings for conducting a flow of compressed air therethrough into the housing, and an exit screen arranged at the outlet end of the housing. The exit screen includes a plurality of exit openings therethrough arranged at an acute angle with respect to the centerline axis so as to provide a flow of compressed air therethrough into a bypass flow passage at least partially in a same direction as a bypass airflow through the bypass flow passage.

Compressor bypass bleed system for a ducted fan engine

A muffling device for exhausting at least one fluid flow in a gas turbine engine includes a first diffuser coupled in flow communication with a first conduit. The first diffuser is configured to exhaust a first fluid flow. The device further includes a second diffuser disposed adjacent the first diffuser. The second diffuser is coupled in flow communication with a second conduit. The second diffuser is configured to exhaust a second fluid flow. The device also includes a third diffuser at least partially surrounding the first diffuser and the second diffuser. The third diffuser is coupled in flow communication with the first diffuser and the second diffuser. The third diffuser includes a body with apertures and is configured to exhaust a third fluid flow. The third fluid flow includes at least one of the first fluid flow and the second fluid flow.
