Problems solved by technology

Different from the straight-rod weathervane, the wedge-shaped weathervane and the rotation axis are respectively connected by a certain angle surface. Due to the difference in the structure of the weather vane, the existing technology cannot be used to measure the wedge-shaped weather vane on both sides of the fuselage.

Abstract

The invention belongs to the field of aviation electromechanical atmosphere data systems, and particularly relates to an attack angle sensor weather vane angle measuring device and method. The attack angle sensor weather vane angle measuring device comprises a base assembly (1), a knob assembly (2), a dial assembly (3), a catcher assembly (4), a bushing 1 (5), a level gauge assembly (6), an adjusting assembly (7) and a base (8). The base (8) is installed at the end of the dial assembly (3) and fixed to the base assembly (1) together with the dial assembly (3), the rotary knob assembly (2) is installed at the end of the base assembly (1), an installation groove is formed in the middle of the dial assembly (3), and the catcher assembly (4) used for fixing a wind indicator is installed above the installation groove. The level gauge assembly (6) is installed on the base (8). The adjusting assembly (7) penetrates through the dial assembly (3) to be in contact with the bushing 1 (5). The device is simple in structure, low in cost and high in measurement precision, and effectively solves the problem of angle calibration of the wedge-shaped weather vane of the attack angle sensor.

Description

technical field [0001] The invention belongs to the field of aviation electromechanical atmospheric data systems, and in particular relates to an angle-of-attack sensor wind vane angle measuring device and method. Background technique [0002] The angle of attack sensor is a supporting product of the air data system. It is installed on both sides of the front fuselage of the aircraft. The wind vane of the angle of attack sensor is a wedge-shaped wind vane, which rotates with the change of the airflow direction, thereby measuring the pitch angle of the aircraft fuselage relative to the airflow. Such as figure 1 shown. In order to accurately measure the flight angle of the aircraft, it is necessary to accurately calibrate the sensor angle. It is necessary to invent an angle measurement device to solve the problem of calibration of the angle of attack sensor wind vane. [0003] The prior art, such as a kind of angle measuring instrument described in CN211601915U, also perfor...
