Composite-material-based paddle torsional angle detection device of unmanned aerial vehicle

Abstract

The invention relates to the field of aircraft paddle torsional angle detection, in particular to a composite-material-based paddle torsional angle detection device of an unmanned aerial vehicle. Thedetection device is composed of a pedestal, a lower paddle root fixation block, an upper paddle root fixation block, a lower profile fixation block, an upper profile fixation block, a tip support block fixed on the pedestal, a paddle root profile measuring clamp clamped at a paddle root of a to-be-detected paddle, a first profile measuring clamp clamped at a body of the to-be-detected paddle, a second profile measuring clamp clamped at the body of the to-be-detected paddle. The lower paddle root fixation block and the upper paddle root fixation block form a first clamping part jointly and thelower profile fixation block and the upper profile fixation block form a second clamping part jointly. According to the composite-material-based paddle torsional angle detection device, the profile measuring clamps are installed at a to-be-detected profile of a paddle naturally and then an angle measuring instrument is installed at a measuring clamp platform, so that a torsional angle is measureddirectly. The detection device has a reliable and stable structure; the measured data are accurate; the paddle quality is ensured greatly; the working efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of torsion angle detection of aircraft blades, in particular to a device for detecting the torsion angle of composite material blades of an unmanned aerial vehicle. Background technique [0002] Composite blades are an essential part of the helicopter rotor system and the core of the helicopter rotor system. The quality of the rotor is directly related to the performance and safety of the helicopter, and the twist angle of the blade is directly related to the flight quality of the blade. The blade twist angle device and method are the key to detect whether the composite material blade twist angle is qualified. [0003] At present, in the torsion angle detection of helicopter composite main blades, torsion angle detection is the key to the production and delivery of blades. Unreasonable detection methods and devices will lead to inaccurate and unstable detection values ​​of blades after forming. Compliance with the ae...
