However, using the error compensation method, when measuring the installation error of the sensor, the angle of attack sensor itself will be used as a measuring tool to measure the installation error of the angle of attack sensor itself according to the change in the output value of the angle of attack sensor. Therefore, this error compensation There are certain limitations in the method, which may damage the rotating parts of the angle of attack sensor
Especially when the overall accuracy requirements of the angle of attack are increased, the accuracy of the angle of attack sensor itself is required to be high. At the same time, the installation error of the angle of attack sensor needs to be re-measured after the angle of attack sensor is replaced. Therefore, the maintainability of the angle of attack sensor will be reduced.

Description
technical field [0001] The invention relates to a device for measuring the installation error of an angle of attack sensor and a measurement method thereof for measuring the installation error of the angle of attack sensor. Background technique [0002] The aircraft angle-of-attack sensor is generally installed on the side of the front fuselage of the aircraft, and is fixed to the airframe by installing an adapter plate. In addition, the above-mentioned installation adapter plate is riveted with the skin of the airframe. The positioning of the above-mentioned aircraft angle-of-attack sensor is realized by using two positioning pins on the sensor mounting plate and two positioning holes on the mounting adapter plate. [0003] In order to measure the accurate local angle of attack, it is usually required that the line of the positioning pins is parallel to the horizontal reference plane of the aircraft, and the output reference of the angle of attack sensor is the center line ...
