Abstract

The invention belongs to aircraft fuel oil supply technology, and particularly relates to an aircraft fuel oil consumption control mechanism and method. The aircraft fuel oil consumption control mechanism is arranged in an oil transportation tank and comprises an oil inlet duct, a servo motor, a rotating joint and an oil transportation duct, wherein the servo motor is coaxial with the rotating joint, a rotating end of the rotating joint rotates around the axis of the rotating joint under control of an external control system and is connected with the oil inlet duct, so that the oil inlet ductrotates along with the servo motor, a fixed end of the rotating joint is connected with an oil transportation duct, and the oil transportation duct penetrates the oil transportation tank and transports oil. The height of an oil inlet of the oil inlet duct relative to the oil level in the oil transportation tank is adjusted by the servo motor, so that the quantity of fuel oil entering the oil inletduct is controlled, and fuel oil consumption is accurately controlled.

Description

technical field

[0001] The invention belongs to aviation fuel supply technology, in particular to an aircraft fuel consumption control mechanism and method. Background technique

[0002] The main function of the aircraft fuel system is to store fuel and deliver it to the engine. Most aircraft have multiple fuel tank compartments, and fuel needs to be transferred between each compartment, and the amount of fuel in each tank must be controlled to keep the center of gravity of the aircraft stable.

[0003] At present, there are two commonly used fuel consumption sequence control methods. One is to use the pipeline direction to connect the fuel tanks in series, and the fuel is consumed in a preset order; Continuously control fuel consumption. The former control method is generally used on small aircraft with a small change in fuel center of gravity. Once the fuel consumption sequence is determined, it cannot be changed and can only meet the pre-planned flight mission requireme...
