The present application relates to a fuel flow system. In particular, the application relates to a fuel flow system for an aircraft. The fuel flow system has a fuel conduit having a fuel inflow and a fuel outflow along which a fuel/water mix is configured to flow from the fuel inflow to the fuel outflow. The fuel conduit is fluidly communicable with a fuel tank. A peripheral conduit surrounds at least part of the fuel conduit. A water-permeable member is disposed between the fuel conduit and the peripheral conduit. The water-permeable member enables water from the fuel/water mix to flow through the water-permeable member from the fuel conduit into the peripheral conduit, but at least substantially prevents liquid fuel from the fuel/water mix from doing so.

A fuel manifold adapted to communicate with at least one fuel tank of an aircraft is presented. The manifold defines an enclosure adapted to be filled with fuel and to have an internal pressure P1 higher than the internal pressure P2 of the fuel tank. The enclosure includes at least one ceiling and at least one side wall provided with overflow holes adapted to communicate with the fuel tank. The manifold includes a mechanism for discharging an air pocket, trapped between the ceiling and the level of the overflow holes, to the fuel tank.

A vessel designed for enclosing at least one sensor is arranged within a fuel tank. The vessel is provided with a fuel inlet connected to a refuelling arrangement of the tank, and with through-holes for the fuel to exit the vessel to the tank or to enter the vessel from the tank. It allows that measurement results which are provided by the sensor during a refuelling operation relate to the fuel currently admitted into the tank, separately from the fuel initially contained in the tank before the refuelling operation has started.

An aircraft fuel cell seal and methods of its use. The disclosed seal takes the form of a pre-cured, partially hollow elongate member that does not subtend a complete circle, but rather leaves an elongate gap in the member that can be placed over an edge or fillet of a fuel cell. In some cases, chambers within the member may be filled with wet sealant to provide redundant protection against EME effects.

An inert gas generation system from a flow of air, notably for an inerting system for at least one aircraft fuel tank. The generation system includes an air circuit having an air inlet, an inert gas outlet, and a first and a second air separation module arranged in series on the air circuit to deplete oxygen within the air and to generate a nitrogen-enriched inert gas.

An aircraft fuel tank, which includes a water sensor, arranged at the bottom of the tank and connected to a calculation and processing mechanism in order to receive a presence of water signal sent by the sensor, and to return information regarding the need, or not, to perform a fuel tank drainage operation.
