Abstract. The article discusses the issues of increasing the efficiency of paint and varnish coating operations on aircraft samples using a flexible industrial robot. The subject of the research is the technological processes of automated application of paint and varnish materials on the surface of aircraft structures of complex geometric shape, as well as methods for improving the quality of coating and productivity of painting work through the use of robotic complexes. The aim of the study is to develop and evaluate a flexible robot control method that improves the efficiency of aircraft painting operations by optimizing the trajectory of the working tool, maintaining the required distance to the surface to be painted and evenly distributing the paint and varnish material over the entire processing area. The developed method is based on the use of a digital model of the painted object, adaptive trajectory planning algorithms for the manipulator and a mathematical apparatus for spatial positioning, which allows taking into account the complex configuration of aircraft surfaces. The method is based on the principles of robotic control of technological processes, computer modeling and automated control of coating parameters in real time. In contrast to the classical model of manual application of paint coatings, the developed method provides higher accuracy in positioning spray equipment, reducing the influence of the human factor, increasing the stability of coating thickness and reducing the consumption of paint and varnish materials. In addition, the use of a flexible robot makes it possible to shorten the duration of the technological cycle, increase the safety of work and ensure the processing of hard-to-reach areas of aircraft structures while maintaining the required coating quality. The results obtained confirm the prospects of introducing robotic technologies into the production and maintenance processes of aviation equipment.
