Abstract

The invention discloses an automatic aircraft weight center of gravity measuring apparatus and a control method thereof. The apparatus herein includes a fixed front scale and a fixed rear scale. The center lines of the fixed front scale and the fixed rear scale are provided with a sliding middle scale thereon, and the fixed front scale, the fixed rear scale and the sliding middle scale form a triangle. The fixed front scale and the fixed rear scale both include a digital weighing table. Each digital weighing table is connected to a lifting structure therebelow. The digital weighing table is also provided with a laser displacement sensor therebelow. The sliding middle scale includes a digital weighing table. The digital weighing table is connected to a lifting structure therebelow. The lifting structure is disposed on a scale sliding module. The apparatus herein can automatically measure the weight center of gravity of various kinds of aircrafts, and effectively addresses great measurement errors and high measurement cost due to differences of weighing devices upon measuring the weight center of gravity of various kinds of aircrafts.

Description

technical field [0001] The invention belongs to the technical field of aircraft weighing, and in particular relates to an automatic measuring device for the center of gravity of an aircraft and a control method thereof. Background technique [0002] The measurement of the center of gravity of the aircraft is an experimental verification of the theoretical center of gravity and an important ground test before the first flight of various types of aircraft. Therefore, the accuracy of the measurement of the center of gravity of the aircraft directly affects the flight safety of the aircraft. According to the principle of measuring the center of gravity of aircraft weight, there are two commonly used measurement methods at present: the jack method and the wheel method. The weight measurement accuracy of the method is high, but the error of the front and main wheelbase measurement of the aircraft has a great influence on the accuracy of the center of gravity measurement. No matte...
