Self-monitoring computer control method for airborne fuel system

Abstract

The invention relates to a self-monitoring computer control method for airborne fuel system. The method collects the information provided by fuel quantity sensors in fuel tanks on an aircraft and a speed signal of an auxiliary power device in real time according to the fuel consumption sequences of an aircraft fuel system and the working states of the auxiliary power device, realizes the computerautonomous controlling on the fuel feeding and fuel delivering of the fuel system by automatically arranging fuel using sequences according to a stipulation (guaranteeing that the center of gravity changes to the minimum), and has characteristics of low power consumption, high reliability, high security and intelligence, so that the states of the fuel system can be monitored in real time, early warning on potential faults of the fuel system can be carried out in advance, pilots can be prompted to make early disposal, and the control reliability of the fuel feeding and fuel delivering of the fuel system can be enhanced; fault diagnosis capabilities of the fuel system can be strengthened, and the fuel feeding and fuel delivering security of the fuel system can be increased; and control partsunder traditional control modes can be decreased, weight of the aircraft can be lightened, and the costs of the aircraft can be reduced.

Description

technical field [0001] The invention belongs to the technical field of avionics and relates to a computer control method for self-monitoring of an airborne fuel system. Background technique [0002] The aircraft fuel system is an important part of the aircraft. It is composed of fuel tanks, ground refueling, fuel delivery, fuel supply, fuel discharge, ventilation pressurization, explosion protection, fuel measurement and indication, and aerial refueling. The working performance of this system It directly affects the safety, maneuverability and combat capability of the aircraft. [0003] The fuel system is to store fuel on the aircraft to ensure continuous and reliable supply of fuel to the engine according to the required pressure and flow under specified flight conditions (such as flight altitude and flight attitude); secondly, to adjust the center of gravity of the aircraft to keep the center of gravity of the aircraft Within the allowable range; the third is the so-calle...

AI Technical Summary

Problems solved by technology

If the order of fuel consumption of each fuel tank is not controlled, the center of gravity of the aircraft will change greatly, affecting the balance of the aircraft

Generally, hydraulic drive is used to realize the oil delivery and fuel supply control of the on-board fuel system, lacking measures such as fuel state monitoring, fault-tolerant control, and misoperation of fuel valves and oil pumps.
