Abstract

A pusher aircraft power plant (10) for propelling an aircraft is configured to improve serviceability of swirl recovery vanes (22). The pusher aircraft power plant (10) includes a prime mover (12) operable to generate motive power, an enclosure (14) housing at least part of the prime mover (12), a bladed rotor (16) drivingly coupled to the prime mover (12) and disposed aft of the prime mover (12), and a plurality of vanes (22) angularly distributed about a rotation axis (RA) of the bladed rotor (16) and being non-rotatable about the rotation axis (RA) 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 disposed aft of the enclosure (14) permitting the vanes (22) to be uninstalled from the pusher aircraft power plant (10) without accessing the enclosure (14).
