Measuring device for weight and gravity center of aircraft

Abstract

A measuring device for weight and gravity center of an aircraft relates to the technical field of electronic measurement and comprises three electronic scales and an industrial personal computer. The measuring device is characterized by further comprising a data converter. The electronic scales are disposed below three wheels of the aircraft respectively and used for weighing the aircraft, and terminals of the electronic scale are connected with the data converter. The data converter acquires the weight of the aircraft and transmits the weight to the industrial personal computer. The industrial personal computer comprises a calculation device, a storage device and a display device. The measuring device combining the electronic scales and the industrial personal computer, real-time measurement and storage of the weight and the gravity center of the aircraft are achieved, and change of the weight and the gravity center of the aircraft can be observed visually. Especially, the weight and the gravity center are dynamically measured during continuous oil delivery and oil discharge of the aircraft in a ground test, so that labor is reduced greatly, work efficiency is improved, and measurement precision is also improved greatly.

Description

technical field [0001] The invention relates to the technical field of electronic measurement, in particular to a measuring device for measuring the weight and center of gravity of an aircraft. Background technique [0002] The weight and center of gravity changes of the aircraft are very important indicators in the flight safety of the aircraft. The fuel of the aircraft is stored in the fuel tanks of the back of the aircraft, the wings, etc., and there is a certain sequence of fuel delivery in the process of using fuel in the flight of the aircraft, that is, in the fuel Under the control of the system, part of the fuel in a certain fuel tank is used first, then part of the fuel in the other fuel tank is used, and then part of the fuel in the other fuel tank is used again and again. As the fuel decreases, the weight of the aircraft and the moment of the center of gravity However, changes in the weight and center of gravity of the aircraft should be within a safe range, other...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when measuring the weight and center of gravity of an aircraft, the original data on the scale are observed on the mechanical scale or the electronic scale platform. And other additional factors, it is necessary to wait until the weighing process is over, and the result of the aircraft weight center of gravity can be obtained through manual secondary calculation processing on the original data, and the actual weight and center of gravity data of the aircraft cannot be read intuitively.

Especially in the process of continuous oil delivery and oil discharge of the aircraft in the ground test, the dynamic calculation of the weight and center of gravity is cumbersome, and the change of the center of gravity during the dynamic process cannot be read intuitively and accurately on the spot
