Aileron folding and unfolding gap detection device and method

By designing an air rudder folding and unfolding gap detection device, a stabilizing force is applied using a locking fixture and a constant force output device, and a distance sensor is used to measure the highest point of the lower surface of the rudder. This solves the problems of multiple operators and errors in air rudder folding and unfolding gap detection, and achieves efficient and accurate detection results.

AI Technical Summary

Technical Problem

Existing methods for detecting the gap between folding and unfolding air rudders require multiple operators, have unstable force values, and contain measurement errors, making it difficult to guarantee the accuracy and efficiency of the detection.

Method used

Design a device for detecting the folding and unfolding gap of an air rudder, including a locking fixture, a constant force output device and a distance sensor. The air rudder is fixed by the locking fixture, the constant force output device applies a stabilizing force, and the distance sensor measures the distance from the highest point of the lower surface of the rudder to the worktable to calculate the folding gap.

Benefits of technology

It enables single-person operation, stable force values, and accurate measurement results, improving detection efficiency and result stability while reducing human error.
