Development of three-point aviation fuel quantity gauge

In response to the well-developed digital technologies, modern methods can be worked out for the spheres where radical changes seemed hardly possible. This paper describes the development of a new method of fuel quantity meas- urement that has not been applied before. To measure the level of fuel in the fuel tank of an aircraft, it is proposed to use three fuel level gauges and a special electronic calculation unit; they model the fuel level surface inside the given volume, and then the actual amount of fuel can also be calculated. This can considerably reduce the evaluation errors allowed with the application of the existing fuel quantity gauges. The main advantage of the system offered is the elimi- nation of the errors arising with the aircraft evolutions and irregular motions. The article gives the analysis of the fuel level assessment methods used in the aviation sphere at present, the types of fuel quantity gauges used in aviation, and the specific conditions of measuring the fuel level in the aircraft fuel tanks. The proposed method has a number of advantages, in comparison with the traditional ways of measuring the fuel level; a basic mathematical model of the aircraft tank fuel level calculation has also been worked out.
