Abstract

A tractor aircraft power plant (10) for propelling an aircraft is configured to improve serviceability of swirl-recovery vanes (22). The tractor aircraft power plant (10) includes an intermittent combustion engine (12) such as a Wankel engine operable to generate motive power. A bladed rotor (16) is drivingly coupled to the Wankel engine (12) and is disposed forward of the Wankel engine (12) relative to a propulsion direction. A gearbox (38) drivingly couples the bladed rotor (16) to the Wankel engine (12). A plurality of vanes (22) are angularly distributed about a rotation axis (PA) of the bladed rotor (16) and are non-rotatable about the rotation axis (PA) of the bladed rotor (16). The vanes (22) are disposed aft of the bladed rotor (16) to interact with a flow of air propelled by the bladed rotor (16) during rotation of the bladed rotor (16). The vanes (22) are mounted to the gearbox (38) to facilitate serviceability of the vanes (22).
