Calibrator of angle of attack sensor of aircraft and horizontal calibration method

Abstract

The invention belongs to the technical field of aircraft ground maintenance, and particularly relates to a calibrator of an angle of attack sensor of an aircraft and a horizontal calibration method. The angle of attack measurement of a middle-sized transport aircraft is performed by a weather vane mounted on the outer side of an aircraft fuselage combined with the angle of attack sensor on the inner side of the fuselage. Such an angle of attack sensor is not provided with a dedicated calibration tool. The calibrator of the angle of attack sensor of the aircraft is used for horizontal calibration of the angle of attack sensor, and includes an angle dial and a horizontal pointer. A support is disposed on the lower surface of the angle dial, and a bubble level bar is disposed on the upper surface of the angle dial. The bubble level bar is parallel to a 0-degree scale line. The horizontal pointer is provided with a bubble level bar in parallel, and a groove hole combined with the weather vane of the angle of attack sensor is formed in the tail end of the horizontal pointer. A plurality of threaded holes communicating with the groove hole are further formed in the tail end of the horizontal pointer, and the weather vane is clamped by adjusting screws. According to the calibrator of the angle of attack sensor of the aircraft and the horizontal calibration method, the maintenance steps are simple, operation is easy, and the horizontal calibration of the angle of attack sensor is convenient.

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-...
