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 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: A fiber-optic sensor including an optical fiber comprising a first Fiber Bragg Grating (FBG) arranged along a first part of the optical fiber; and a first element disposed on an outer surface of the optical fiber, the first element having a first coefficient of thermal expansion (CTE) different to a CTE of the optical fiber, and being configured to induce a change in strain across the FBG in response to a change in temperature of the fiber-optic sensor in the region of the first FBG, the first element bonded to the optical fiber at two first locations that are separated, along the optical fiber from one another by the first part and unbonded to the optical fiber along the first part.

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.

Abstract: A fuel system includes a chamber for storing a fuel, an optical differential pressure sensor, and one or more processors in communication with the optical differential pressure sensor. The optical differential pressure sensor is fluidically connected to the chamber and is configured to, when the fuel is stored in the chamber, output a signal indicative of a pressure difference in the optical differential pressure sensor to the one or more processors.
