Aerial fuel supply system for aircrafts

Abstract

The invention provides an aerial fuel supply system for aircrafts, wherein an aerial fuel supply control panel controls start and stop of aerial fuel supply through a refueling switch, a fuel measurement and control system is used for transmitting fuel level information of each fuel tank to a refueling control box and a supply state display system, a display control system is used for transmitting aircraft load information to the refueling control box, the refueling box may control opening and closing of each fuel tank refueling valve according to actual fuel levels and theoretical full levels, may also calculate aircraft weight and aircraft center of gravity and transmit results to the supply state display system and closes all the refueling valves immediately if the aircraft weight exceeds a set value or the aircraft center of gravity exceeds a set rang, and may also judge whether aerial fuel supply is used as a refueling mode or not according to wheel load signals, and the supply state display system is used for displaying total fuel level information, weight information and gravitational center information of the aircraft and is also suitable for displaying the fuel level information of each fuel tank of the aircraft and the refueling state of each fuel tank.

Description

technical field [0001] The invention relates to the technical field of aircraft aerial refueling, in particular to an aircraft aerial refueling system. Background technique [0002] When the aircraft is flying, in order to increase its range and increase its endurance time, it is necessary to use aerial refueling technology. Air refueling is to refuel another aircraft or several aircraft (or helicopters) in the air. The plane that refuels is a refueling plane, and the plane that receives fuel refueling is a refueling plane. The application of aerial refueling technology greatly enriches the flexibility and diversity of the plane, improves the maneuverability and time of the plane, and increases the The flight range provides a good technical equipment reserve for the aircraft. [0003] According to the refueling method, aerial refueling technology can be divided into plug-cone refueling, that is, soft refueling, and telescopic pipe refueling, that is, hard refueling.

AI Technical Summary

Problems solved by technology

[0003] According to the refueling method, aerial refueling technology can be divided into plug-cone refueling, that is, soft refueling, and telescopic pipe refueling, that is, hard refueling. According to the development requirements of a large aircraft, the aircraft should have the ability to receive soft refueling in the air, and The requirements for the total amount of oil received and the oil flow rate are more than twice that of the oil receivers in service in my country. In this case, it is necessary to take into account the refueling mechanism of the ground pressure refueling system and meet the requirements for the fuel flow rate. During the refueling process, the weight center of gravity of the aircraft appears to exceed the limit or the amount of fuel is unbalanced. There is no air refueling system that can meet this standard in the prior art
