The subject matter of this article is the technological features analysis of the initial and repair of aircraft products painting. The goal is to analyze and systematize the trends in the global aircraft industry in the pneumatic painting technology field and the removal of old paintworks from the outer aircraft product surfaces. The tasks include analysis of directions for improving the pneumatic painting technology; analysis of laser removal technological features of old paintwork. The following results were obtained. The analysis of publications showed significant advantages of the electrostatic pneumatic painting system with limitations for composite materials. Relevant is the development of new paintwork materials with a reduced content of volatile organic compounds and an increased hiding power, as well as fundamentally new water-based paintwork systems. One of the modern means of technological equipment for pneumatic painting is an overhead crane-telescopic platform. The global trend is the creation of painting and service centres and robotization of paintwork. The laser removal technology of old paintwork is an effective innovative alternative to the methods of abrasive or chemical-mechanical cleaning from the outer aircraft product surfaces, which are currently used. The laser cleaning technology should provide the possibility of manual or automatic old paintwork removal from the double curvature surfaces, fastening elements, as well as the joints of the sheathing sheets without thermal damage to the anode film on the aluminium alloys’ sheathing. Laser stands and mobile laser platforms have high productivity and low labor intensity, multiple reductions in the disposing cost of the decomposition of old paintwork products, compliance with labor protection and environmental requirements compared to existing technologies. Conclusions. The scientific novelty of the materials presented in the article is shown by the analysis and systematization of the technological features of the aircraft products initial and repair painting; rationality substantiation for creating the painting and service centre for the Ukraine aviation industry; determination the directions of scientific and applied research on the laser removal technology of old multilayer paintwork.
