Abstract

The invention relates to the technical field of level measurement and particularly provides a method for dynamically measuring fuel capacity of an irregular fuel tank of an aircraft; the method comprises: acquiring fuel volume characteristic data of each sensor, selecting a suitable function formula, fitting data of each sensor at all measurable angles, calculating maximum and relative errors , using the formula if an error index is satisfied, selecting other formulas or segmenting unsatisfactory index points if the index is not satisfactory until the index is satisfactory, receiving sensor data and aircraft attitude parameters, acquiring effective sensor formula fitting parameters, calculating fuel volume solved by each sensor to obtain fuel volume value of a single fuel tank, syncing aircraft fuel level angle and sensor height information under dynamic conditions according to test or trial data so as to obtain more accurate fuel volume of the fuel tank.

Description

technical field

[0001] The invention relates to the technical field of liquid level measurement, in particular to a dynamic measurement method for the fuel volume of an irregular fuel tank of an aircraft. Background technique

[0002] During aircraft ground maintenance and flight, the amount of fuel in the fuel tank under different aircraft attitudes is an important factor to ensure safe flight and return. By measuring the fuel volume of each fuel tank on the aircraft, the remaining fuel volume, fuel consumption speed and fuel tank status of the aircraft are fed back to the pilot to ensure that the pilot knows the fuel usage situation in a timely manner. On the one hand, it can improve flight safety; on the other hand, it can Assist to actively adjust the center of gravity, improve economy, and increase the effective range of the aircraft.

[0003] Modern aircraft generally use the wing or fuselage frame and wall panels to construct integral structural fuel tanks as fuel st...
