How to refuel a plane in the air quickly and reliably?

PATENT:

2796040

INVENTION:

Squeeze fuel valve

INNVENTOR(S):

Kopytin Sergey Ivanovich

PATENTEE:

Public Joint Stock Company “United Aircraft Corporation” (PJSC “UAC”)

PURPOSE:

For reliable refueling of aircraft in the air

INNOVATION:

Aerial refueling allows to significantly prolong flight time,providing the necessary flight range. Devices for pumping fuel and drainage of aircraft fuel systems, in particular, refueling pods (RP) must have a simple and reliable design of the squeeze fuel valve. It provides fuel supply to the RP when refueling in the air and stopping the fuel supply when the RP is discharged. In this invention, the valve is made in the form of two bodies inserted into each other so that angular movement on a spherical surface is possible. A fuel channel is formed between the bodies. The valve of this design opens when the inner body is connected to the receiver of the pumped fuel. Due to the simplicity of the design of the squeeze fuel valve, its reliability, ease of maintenance and repair increases. The hinged pair allows to compensate for the mounting deviations that occur when the tip of the flying boom is docked with the receiver of the pumped fuel.

SCOPE OF
APPLICATION:

The invention can find application in aviation technology, namely in devices for pumping fuel and drainage of fuel systems of aircraft, to increase the flight range and the ability of air transport to carry large payloads.
