Abstract: Tip surfaces of aerofoils of a bladed disk are repaired by an additive layer manufacturing process in which a laser beam is directed at the tip surface to create an interaction zone while metallic powder is delivered from powder delivery nozzles onto a locus of delivery of larger area than the interaction zone. The bladed disk and the powder delivery nozzles are situated within a controlled environment enclosure, while a laser generating the laser beam is situated outside the enclosure. The laser interaction zone trajectory is controllable independently of the movement of the powder delivery nozzles and so can execute rapid accelerations and decelerations, and changes of direction, enabling complex space filling scanning patterns to be performed on the tip surface.

Abstract: A sleeve for retaining magnets around a rotor of an electrical machine. The sleeve is cylindrical and hollow, having axial length and having radial thickness between its inner surface and outer surface. The sleeve defines a plurality of axially spaced, circumferentially extending grooves. Each groove has radial depth which is less than the radial thickness of the sleeve.
