IN-FLIGHT FUEL RECEIVER HEAD Russian patent published in 2022 - IPC B64D39/06 

FIELD: aviation.

SUBSTANCE: invention relates to in-flight refueling devices. The fuel receiver head of the in-flight refueling system comprises a body (1), a spring-loaded fuel valve (2) located inside the head body, and a tip (3). On the body (1) of the head from the side of the conical chamfer at a distance of 67.23 mm from the auxiliary diameter on the conical surface (8) of the lock groove (6), equal to 95.25 mm, an end support surface is made, at a distance of 6.81 mm from which placed toroidal sector. The flange (15) of the fuel valve is provided with a cylindrical end ledge (17), the outer diameter of which is approximately equal to the diameter of the end bearing surface of the body (1) of the head. Distance from the auxiliary diameter on the conical surface (16) of the flange (15) of the valve (2), equal to 76.2 mm, to the auxiliary diameter on the conical surface (8) of the lock groove (6) of the body (1) of the head, equal to 95.25 mm, with the fuel valve (2) supported on the body (1) of the head, is equal to 79.73 mm.

EFFECT: increased performance of the head of the fuel receiver of the refueling aircraft by providing reliable sealing of the connection with any known standard contact assembly of the cone-sensor of the refueling aircraft.
