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.
Claims13
An aircraft system, comprising:
- a wheel supported on an axle by a first bearing and a second bearing;
- a first fibre optic sensor provided at the first bearing for sensing a strain or temperature of the first bearing;
- a second fibre optic sensor provided at the second bearing for sensing a strain or temperature of the second bearing;
- and
- an interrogator configured to receive optical signals from the sensors, and analyse the optical signals to determine differences in the strains or temperatures of the first bearing and the second bearing.
An aircraft wheel assembly comprising a wheel supported on an axle by a first bearing and a second bearing, a first fibre optic sensor extending around the first bearing for sensing a strain or temperature of the first bearing, and a second fibre optic sensor extending around the second bearing for sensing a strain or temperature of the second bearing.
A sensor arrangement for an aircraft comprising a wheel supported by a first bearing and a second bearing, comprising:
- a first fibre Bragg grating sensor for sensing a strain or temperature of the first bearing;
- a second fibre Bragg grating sensor for sensing a strain or temperature of the second bearing;
- and
- an interrogator for receiving optical signals from the sensors, and for analysing the optical signals to determine differences in the strains or temperatures of the first bearing and the second bearing.
