Abstract

The invention discloses an active infrared nondestructive test unmanned plane system and belongs to the field of a nondestructive test on a large complex member such as an aerospace structural component. The system solves the problem that the aerospace structural component has a large volume and a complex structure so that manual climbing checking efficiency is low and potential safety hazard exists. The system comprises an unmanned plane main body, an unmanned plane mounted monitoring module is arranged on the unmanned plane main body, a ground-based computer transmits a position instruction in a wireless way to control the unmanned plane main body so that the unmanned plane main body is moved to a certain position on the outer surface of a tested object, a data acquisition card controls a modulating signal and power of a laser according to an acquisition instruction, light beams transmitted through the laser go through optical fibers, are collimated through a collimating lens and irradiate the outer surface of the tested object, an infrared camera acquires an image sequence and the ground-based computer carries out phase locking operation on the acquired image sequence and a reference signal so that a thermal radiation signal amplitude image and a phase image of the tested object are obtained and defect types and positions are obtained.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle for detecting aerospace structures, which belongs to the field of non-destructive testing of large and complex components such as aerospace structural parts. Background technique [0002] With the continuous development of aviation and aerospace manufacturing technology, composite materials have been widely used for their high specific strength, specific stiffness, good fatigue resistance and corrosion resistance. However, due to manufacturing errors and defects caused by load, vibration and other factors of composite materials, the performance of aerospace structural parts will be seriously affected. Therefore, it is particularly important to realize efficient online detection of aerospace structural parts. Aerospace structural parts are large in size and complex in structure, and the efficiency of personal inspection by personnel ascending to the heights is low and leaves hidden dangers to safety. ...
