The article discusses methods for improving the energy efficiency of fixed and variable pitch propellers by applying an innovative electrostatic water-repellent coating to the blade surface. The objective of the study was to develop methods to reduce the propeller drag, which helps to reduce energy consumption and improve the energy efficiency of the propeller group. The effect of water-repellent coatings on reducing air resistance and improving aerodynamic characteristics, which directly affects fuel economy and energy efficiency, has been studied.To achieve this goal, the article proposes to use electrostatic coatings that minimize the negative impact of humidity on the blade surface and reduce friction between the blade and air flow. A comparative analysis of the effectiveness of various methods of improving the energy efficiency of propellers was carried out, as well as an assessment of the economic benefits of using water-repellent coatings.The results of the research confirmed that the application of such coatings can reduce the drag of the propeller, which in turn contributes to increased thrust and a significant reduction in energy costs for the operation of the propeller.It also helps to reduce fuel consumption and improve the fuel and economic characteristics of propeller systems, which has a direct impact on the energy efficiency of aircraft. By reducing drag and improving aerodynamic properties, the use of electrostatic water-repellent coatings also has the potential to reduce energy costs in conditions of variable weather factors, such as high humidity levels. The results obtained have the potential to significantly improve the efficiency of aviation systems, reduce their energy consumption and increase overall energy efficiency.The research provides new opportunities for the development of energy-efficient technologies in the aviation and energy sectors, which contributes not only to increased productivity but also to reduced environmental impact through energy savings and reduced CO2 emissions.
