An arrangement for controlling flow of fluid to a component of a gas turbine engine, the arrangement comprising: a conduit, coupled to a supply of fluid, for providing fluid to the component of the gas turbine engine; a magnetic valve for at least partially restricting the conduit and having a valve member with at least a first configuration in which the conduit is at least partially restricted and a second configuration in which the conduit is relatively open, wherein the configuration of the valve member is controlled by magnetic flux in a magnetic circuit which includes at least one member comprising ferromagnetic material, whereby the configuration is responsive to the temperature of the ferromagnetic material.

A rotorfor an electrical machine comprising a rotor body, at least one magnetcoupled to the rotor bodyand a retainerfor retaining the at least one magnetto the rotor body, the retainercomprising at least one elongate fibre in a metal matrix.

Rotor for an electrical machine

Condition monitoring of an electrical machine is achieved by using electro-magnetic finite element analysis to analyse the machine based on model parameters corresponding with at least one fault condition. This allows the effect of the fault condition to be predicted. Metrology is used to recover live measurements for comparison with the predictions from the electro-magnetic finite element analysis to identify any fault signatures within the live measurements, in principle allowing those faults to be detected or diagnosed before they become catastrophic.
