Abstract
A method of manufacturing a rotor for a generator of an aircraft engine. The method includes providing a rotor body; mounting at least one magnet on the rotor body; wrapping a tow around the rotor body and the at least one magnet to form a wrapped tow having a plurality of layers overlaid in the radial direction; and curing the wrapped tow to form at least a part of a fibre-reinforced composite sleeve configured to retain the at least one magnet on the rotor body. The step of wrapping includes applying a controlled tension to the tow during wrapping. The controlled tension is varied according to the radial position of the layer being wrapped.

A method of manufacturing a rotor for a generator of an aircraft engine, the method comprising:
- providing a rotor body;
- mounting at least one magnet on the rotor body;
- wrapping a tow, comprising elongate fibres and a curable matrix, around the rotor body and the at least one magnet to form a wrapped tow having a plurality of layers of the tow overlaid in a radial direction;
- and
- curing the wrapped tow to form at least a part of a fibre-reinforced composite sleeve configured to retain the at least one magnet on the rotor body,
- wherein the step of wrapping comprises applying a controlled tension to the tow during wrapping, and wherein the controlled tension is varied according to a radial position of the layer being wrapped such that the controlled tension applied to at least one radially inner layer of the wrapped tow is higher than the controlled tension applied to at least one radially outer layer of the wrapped tow.
