Fuel manifold for an aircraft tank
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 P 1 higher than the internal pressure P 2 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.
1. A fuel manifold adapted to communicate with at least one fuel tank of an aircraft, said manifold defining an enclosure adapted to be filled with fuel, the enclosure comprising at least one ceiling and at least one side wall provided with overflow holes adapted to communicate with the fuel tank, wherein the manifold comprises means for discharging an air pocket trapped between the ceiling and the level of the overflow holes to the fuel tank, wherein the discharge means assume the form of at least one hose having at least one inlet arranged between the ceiling and the level of the overflow holes, and an outlet arranged outside the manifold and adapted to communicate with the fuel tank.
2. The manifold according to claim 1 , wherein the ceiling of the enclosure is concave.
3. A fuel manifold adapted to communicate with at least one fuel tank of an aircraft, said manifold defining an enclosure adapted to be filled with fuel, the enclosure comprising at least one ceiling and at least one side wall provided with overflow holes adapted to communicate with the fuel tank, wherein the manifold comprises means for discharging an air pocket trapped between the ceiling and the level of the overflow holes to the fuel tank, wherein the discharge means assume the form of at least one inclined face connecting the side wall and the ceiling, and positioned such that the overflow holes are arranged flush with said inclined face.
