Abstract: An assembly having a bearing with an axis of rotation, and a fibre-based sensor for sensing strain or temperature of the bearing is disclosed. The sensor extends in a direction parallel to the axis of rotation. An aircraft system is disclosed including a wheel supported on an axle by a first bearing and a second bearing. The system further includes a first fibre optic sensor for sensing a strain or temperature of the first bearing, a second fibre optic sensor for sensing a strain or temperature of the second bearing, and an interrogator to analyse optical signals from the sensors to determine differences in the strains or temperatures of the first bearing and the second bearing.

Abstract: The volume of a liquid such as cryogenically stored liquid hydrogen in a container such as a fuel tank on an aircraft is measured using acoustic sensors. The container includes multiple chambers each arranged to accommodate a volume of liquid. A computer processor processes signals from acoustic sensors that detect sound and/or vibration from each chamber and provides an indication of the volume of liquid in the container. Such sounds and/or vibrations may arise inherently from the liquid contained therein.

Abstract: A system installed on an aircraft. The system includes a memory storing static information in one or more optical fibre gratings; and an interrogator. The interrogator includes a light source configured to transmit interrogation light to the memory, a receiver configured to receive return light from the memory, and an analyser configured to analyse the return light to obtain the static information.

Abstract: An apparatus for determining the position of an object having one or more magnetic elements. The apparatus includes magnetostrictive optical sensors, each arranged to produce a signal which is indicative of a proximity of the sensor to the one or more magnetic elements. The apparatus is arranged to determine the position of the object based on a plurality of such proximity signals.
