REFUELING DEVICE FOR AN AIRCRAFT, METHOD FOR COMMISSIONING AND METHOD FOR REFUELING WITH SUCH A DEVICE Russian patent published in 2022 - IPC B64F1/28 B67D7/08 

FIELD: aircraft technology.

SUBSTANCE: invention relates to refueling an aircraft. The device for refueling the aircraft contains a deformable pipe (40) for transferring fuel, at the far end (43) of which a wing attachment device (42) is installed, designed to connect it to the inlet of the fuel tank of the aircraft. The first sensor for measuring pressure values (P) is installed in a deformable pipe (40) near the wing attachment device (42). The filling device also contains a second sensor for measuring the flow pressure values in front of the deformable pipe (40) and a block for calculating the value of the flow pressure drop in the deformable pipe (40) based on the pressure values (P) measured by the first and second sensors, as well as a means for determining fuel consumption in the deformable pipe. The unit for comparing the calculated differential pressure value with the reference value is installed at the commissioning stage, for example, for the same flow rate.

EFFECT: increase in the reliability of refueling of the aircraft is achieved.
