Abstract: A method of measuring a height of a fuel in an aircraft fuel tank (21)b including illuminating the fuel in the aircraft fuel tank and detecting reflected light from the fuel. Optical coherence tomography is used to determine the height of a surface of fuel in the fuel tank. An apparatus (30) is used to measure a height of a surface of fuel in an aircraft fuel tank, and an aircraft fuel tank system with a fuel tank and an apparatus for measuring a height of a surface of fuel in the aircraft fuel tank.

Abstract: A method of estimating a quantity of a liquid fuel in a fuel tank of an aircraft is disclosed. A surface of the fuel is illuminated with light so that the light is reflected or scattered by the surface of the fuel onto an array of sensors. The light travels to and from the surface of the fuel via a measurement path containing a transmission medium. A measured time of flight is made at each sensor for the light which travels via the measurement path to that sensor. At least one of the sensors is illuminated with light via a reference path containing a transmission medium with substantially the same refractive index as the transmission medium in the measurement path, the reference path having a known reference distance which does not vary in accordance with the quantity of the fuel.

Abstract: An optical sensor system with two or more optical sensors; two or more receivers; and an optical de-multiplexing system. Each optical sensor includes a fibre grating with a different wavelength characteristic. Each receiver includes a slope filter and a light detector and is associated with a respective one of the optical sensors. The optical de-multiplexing system is arranged to route light from each of the optical sensors to its associated receiver based on a wavelength of the light.

Abstract: A tank assembly with a tank for storing liquid hydrocarbon, the tank having a floor for supporting a weight of the liquid hydrocarbon. A filter is fitted to the floor of the tank. The filter is arranged to allow liquid water in the tank to drain out of the tank through the filter but substantially prevent the liquid hydrocarbon in the tank from doing so. The filter has a permeation member, such as a membrane, which is formed from a material such as graphene oxide which allows liquid water in the tank to drain out of the tank by permeating through the permeation member but substantially prevent the liquid hydrocarbon in the tank from doing so.

Abstract: A dehumidifier comprises: a first channel for transporting air at a first pressure; a second channel for transporting air at a second pressure lower than the first pressure; and a graphene oxide barrier separating the first channel and the second channel. The relatively lower pressure of air in the second channel causes water vapor to be drawn out of the air in the first channel.

Abstract: A fiber-optic communication system for an aircraft including: a light source operable to generate light; a transceiver in optical communication with the light source, the transceiver including a control input and a reflector; an optical fiber in optical communication with the transceiver; and a light detector in optical communication with the optical fiber. The transceiver is operable to generate an amplitude modulated light signal by selectively reflecting the light received from the light source into the optical fiber using the reflector according to information received at the control input. The light detector is operable to receive the amplitude modulated light signal from the optical fiber and to detect an amplitude of the amplitude modulated light signal to extract the information.

Abstract: A communication apparatus includes an optical fiber along which radiation can be transmitted; an optical fiber grating formed within the optical fiber, the optical fiber grating having a structure, and configured to reflect radiation at a particular wavelength; and an instrument coupled to the grating and configured to controllably modify the structure of the grating, thereby changing the wavelength at which the grating reflects radiation. A communication system including the communication apparatus is also described, along with a method of communicating a signal.
