Abstract

A propulsion system (20) for an aircraft includes a propulsion rotor, an engine (22), a propulsor module (24), and a blended exhaust system. The engine (220) has an axis (48), is mechanically coupled to the propulsion rotor, and includes an exhaust section (38). The propulsor module (24) includes a housing forming a propulsor duct with a duct inlet and duct outlet, and a propulsor assembly (94) with an electric motor (112) coupled to a bladed propulsor disposed within the propulsor duct. The blended exhaust system includes an exhaust duct assembly having an engine exhaust inlet at the exhaust section, a propulsor exhaust inlet at the duct outlet, and a blended exhaust outlet. The exhaust duct assembly is configured to receive an engine exhaust stream and a propulsor exhaust stream, form a blended exhaust stream including both, and direct the blended exhaust stream out of the blended exhaust system through the blended exhaust outlet.
