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.

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is further described:

[0026] like figure 2 As shown, the present invention is a multifunctional probe total pressure pipe pressurizing device. It includes base assembly 1 , knob assembly 2 , dial assembly 3 , catcher assembly 4 , bushing 15 , level gauge assembly 6 , adjustment assembly 7 and base 8 .

[0027] like image 3 As shown, the base assembly 1 includes a base 13, two pins 11, two screws 12 and a cursor 14. The two pins 11 and the two screws 12 position the base 13 relative to the sensor flange so that the angle The rotation center of the measuring device is consistent with the sensor center. The base 13 is provided with a V-shaped groove 131 similar in shape to the sensor vane 9 , for the sensor vane 9 to pass through.

[0028] like Figure 4 and Figure 5 As shown, the knob assembly 2 includes a knob 21 , a leaf spring 22 , a knob bracket 23 , a bushing 224 , and a gear shaft 25 . ...

Abstract

The invention belongs to the field of aviation electromechanical atmospheric data systems, and in particular relates to a wind vane angle measurement device and method of an angle of attack sensor. The angle measuring device of the angle of attack sensor of the present invention comprises a base assembly (1), a knob assembly (2), a dial assembly (3), a catcher assembly (4), a bushing 1 (5), and a level assembly (6) , the adjustment component (7) and the base (8). The base (8) is installed on the end of the dial assembly (3) and is fixed on the base assembly (1) together, the knob assembly (2) is installed on the end of the base assembly (1), and the dial assembly ( 3) An installation groove is arranged in the middle, and a catcher assembly (4) for fixing the weather vane is installed above the installation groove. The level gauge assembly (6) is installed on the base (8) through the bushing 1 (5), and the adjustment assembly (7) Pass through the dial assembly (3) in contact with the bushing 1 (5). The invention has the advantages of simple structure, low cost and high measurement accuracy, and effectively solves the problem of wedge-shaped weather vane angle calibration of the angle of attack sensor.

Description

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