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