Description

technical field [0001] The invention relates to a rebound-type angular displacement measuring device, in particular to a device and a method for measuring the deflection angle of an aircraft rudder surface (401), belonging to the field of aeronautical engineering test and detection. technical background [0002] At present, in the measurement of the deflection angle of the aircraft rudder surface (401), the measurement of the deflection angle of the rudder surface (401) is often completed by modifying it for a specific rudder surface (401); or designing special fixtures and connectors, Use a general-purpose angular displacement sensor, inclination sensor or electronic compass to measure the deflection angle of the rudder surface (401), as follows: [0003] 1. To modify a specific rudder surface (401), it is necessary to design and complete the deflection angle measuring unit according to the structure of the aircraft rudder surface (401), and combine it with the rudder surfa...

AI Technical Summary

Problems solved by technology

The result of the transformation of the rudder surface (401) may affect the original functional characteristics such as the strength of the rudder surface (401). On the other hand, the process of transforming the aircraft rudder surface (401) is complicated and difficult to implement, resulting in high cost. and not universal

[0004] 2. Design special fixtures and connectors. When using a general-purpose angular displacement sensor to measure the deflection angle of the rudder surface (401), it is necessary to assemble these scattered fixtures, connectors and angular displacement sensors. The longitudinal and transverse dimensions are large. It takes up a lot of space and brings great difficulties to on-site installation and use

[0005] 3. When using the inclination sensor to measure the deflection angle of the rudder surface (401), due to the low dynamic response frequency of the inclination sensor, it is difficult to measure the dynamic characteristics, and the inclination sensor can only be used to move the rudder on the vertical plane such as elevators and ailerons. Measurement of Surface (401) Deviation Angle

[0006] 4. When using the electronic compass to measure the deflection angle of the rudder surface (401), it is also difficult to measure the dynamic characteristics due to the low dynamic response frequency of the electronic compass, and the electronic compass is easily affected by the ferromagnetic environment, so it is difficult to adapt to the aircraft rudder Measurement of Surface (401) Deviation Angle
