An aircraft angle-of-attack sensor calibrator and level calibration method

Abstract

The invention belongs to the technical field of aircraft ground maintenance, and in particular relates to an aircraft angle-of-attack sensor calibrator and a level calibration method. The angle of attack measurement of medium-sized transport aircraft is carried out through the wind vane installed on the outside of the aircraft fuselage combined with the angle of attack sensor inside the fuselage. There is no special calibration tool for this type of angle of attack sensor. In order to solve the above-mentioned technical problems, the aircraft angle-of-attack sensor calibrator of the present invention is used for the horizontal calibration of the angle-of-attack sensor, comprising an angle dial and a level pointer, the lower surface of the angle dial has a support, and the upper surface has a bubble level, and The bubble level is parallel to the 0° scale line; the level pointer is installed with a bubble level in parallel, and the level pointer has a slot combined with the weather vane of the angle of attack sensor at the end, and also has several threaded holes communicating with the slot. Clamp the vane by adjusting the screw. The invention has simple maintenance steps, is easy to operate, and is convenient for horizontal calibration of the angle of attack sensor.

Description

technical field [0001] The invention belongs to the technical field of aircraft ground maintenance, and in particular relates to an aircraft angle-of-attack sensor calibrator and a level calibration method. Background technique [0002] The angle of attack of the aircraft is the angle between the wing chord of the aircraft and the relative wind speed. It is one of the important atmospheric data. The aircraft's fire control system, cruise control system and stall warning system cannot do without the information of the aircraft's angle of attack. Therefore, when the aircraft angle-of-attack sensor is installed, it is very important to carry out effective horizontal calibration and measurement. [0003] The angle-of-attack measurement of medium-sized transport aircraft is carried out through the wind vane installed on the outside of the aircraft fuselage combined with the angle-of-attack sensor inside the fuselage. There is no special calibration tool for this type of angle-of-...
