Aircraft Fuel Volume Characteristic Calculations and Multi-Sensor Technology on Fuel Volume Measurement Simulation

Abstract:

Owing to the reasons of aircraft attitude error and fuel surface sloshing, the current measurement methods which use the height value of fuel sensor, flight attitude angle and aircraft acceleration information to determine the position of the fuel surface and calculate the fuel volume are inaccurate. This paper applies CATIA secondary development to automatically establish the volume characteristic database which includes various fuel surface angles and height of fuel sensors; A plurality of fuel sensors are arranged reasonably in the fuel tank to ensure that there are at least three sensors immersed in the fuel in each attitude angle, then the fuel surface is determined directly by the measured height of several fuel sensors, and fuel surface parameters are put into a simulation software as input parameters which are designed to measure the fuel volume and calculate the fuel volume in the fuel tank by interpolating. Besides, rotation test platform is designed for aircraft fuel tank with two degrees of freedom to simulate aircraft fuel measurement process. The experimental data can verify the accuracy of multi-sensor fuel measurement system.
