An aircraft fuel system, comprising: a fuel tank; a fuel line; and an engine; wherein the fuel line includes a first conduit configured to carry fuel from the tank towards the engine, and a second conduit configured to carry fuel from the engine towards the tank, wherein one of the first conduit or the second conduit is disposed annularly around the other of the first conduit or the second conduit. Also, a method of operating the system. The system may be used to suppress ice formation in the first conduit and/or provide leakage detection.

Aircraft fuel system with fuel return from engine

An aircraft fuel tank arrangement for the relief of a pressure differential between the interior of the aircraft fuel tank and the ambient atmosphere is provided. The aircraft fuel tank arrangement comprises a removable cartridge received within a cartridge-receiving body located at least partially in the fuel tank, said cartridge comprising a first burstable member operable to rupture in the presence of a pressure differential between the interior of the aircraft fuel tank and the ambient atmosphere which is greater than a predetermined pressure differential.

A fluid flow control valve is housed within a canister () which is semi-permanently fixed in the wall () of a fuel tank, and has pipe connections (). The movable valve parts, including a valve sub-assembly () and an electrical actuator (), may be removed without requiring access to the fuel tank.

An aircraft fuel tank system comprising an aircraft fuel tank and a time domain reflectometry (TDR) fuel gauge for measuring a filling level of fuel in the aircraft fuel tank. The TDR fuel gauge comprises an electromagnetic signal generator and a cable, the cable comprising a first cable part and a second cable part which are coupled in series to the signal generator. The first cable part extends downwardly within the fuel tank and the second cable part extends upwardly within the fuel tank. The first and second cable parts are arranged such that for at least one filling level the first cable part extends down into the fuel from an ullage space at a first location and the second cable part extends up out of the fuel into an ullage space at a second location which is spaced apart from the first location.

A method of installing fuel system components in an aircraft wing in which the fuel system components are attached to ribs before the ribs are assembled into the wing. The ribs are structural ribs for the wing and may be assembled to form a combined rib and fuel system component assembly before the assembly is added to the wing.

An aircraft comprising a Rubens' tube for distributing gas within the aircraft. The Rubens' tube comprises a tube with a plurality of outlets; an inlet for feeding the gas into the tube; and a loudspeaker arranged to set up a standing acoustic wave within the tube. Typically the Rubens' tube is arranged to feed inert gas into a fuel tank of the aircraft.
