On the Issue of Laser Selective Removal of Paint Coating from a Sample of Metal Plating of Aircraft Gliders

Abstract

In this paper the temperature fields in the zone of processing of paint coatings by laser radiation of a sample of the metal skin of aircraft gliders with selective (layer-by-layer) removal are researched. The performed theoretical studies and numerical calculations made it possible to carry out practical tests and develop conditions under which the physical effect of laser energy causes minimal damage to the alloys and composites of the sample, as well as to assess the effect of the laser on the properties of materials used in the aerospace industry. The obtained results are reflected in the technology of laser selective removal of paint coatings from metal and composite skin of aircraft gliders.
