    Abstract: Some water drain valves tend to fill with water which may freeze, thereby jamming the valve. This invention provides an aircraft water drain valve comprising a passageway, a shaft, a first sealing member and a second sealing member. The shaft is moveable between an open position in which the first and second sealing members are arranged to allow free passage of fluid through the passageway, and a closed position in which both the first and second sealing members are arranged to prevent free passage of fluid through the passageway thereby preventing ingress of fluid into the region between the first and second sealing members. Thus water may be hindered from collecting and freezing in the part of the valve close to the cold wall of the fuel tank.

    Abstract translation: 一些排水阀倾向于充满可能冻结的水，从而堵塞阀门。 本发明提供了一种飞机排水阀，其包括通道，轴，第一密封构件和第二密封构件。 轴可以在其中布置有第一和第二密封构件的打开位置之间移动以允许流体自由地通过通道，以及闭合位置，其中第一和第二密封构件都布置成阻止流体自由通过 该通道由此防止流体进入第一和第二密封构件之间的区域。 因此，水可能阻碍在靠近燃料箱的冷壁的阀的部分中收集和冷冻。

    Abstract: The invention includes a method of mounting a component to the skin of an aircraft. The component can include a drain valve, a gas cap, other external fuel instrumentation such as sensors, and antennae. One aspect of the invention includes a new method of mounting a drain valve to an aircraft fuel tank. The drain valve in the method includes any conventional drain valve having a stem and a flange that surrounds the stem. The method includes applying a material around a drain opening of the fuel tank; the material directs an electric charge away from the drain valve.

    Abstract: The fuel pumping system for delivering fuel to an engine includes a fuel transfer circuit for directing fuel from a fuel supply tank to the engine, a fuel boost pump, a main fuel pump and an accumulator device positioned along the transfer circuit between the boost pump and the engine for accumulating fuel and vapor so as to provide a reserve supply of fuel to the engine while minimizing the amount of undissolved vapor delivered to the engine. The system includes a return passage communicating, at one end, with the accumulator and at an opposite end with the fuel transfer circuit upstream of the boost pump for directing fuel and vapor from the accumulator into the transfer circuit.
