Abstract
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...
