Winglets or wingtips of various types are a common means of improving fuel efficiency of a modern aircraft. Aircraft manufacturers and research teams are actively searching for new types of winglets. The purpose of this work is to compare the efficiency of a number of used and promising end superstructures of different shapes. The paper presents the results of a numerical experiment to assess the effect of the four types of wingtips on the isolated wing aerodynamic characteristics. The increase in aerodynamic quality and the change in the inductive resistance of the wing, as well as the intensity of the end vortices, are compared. Validation of the numerical calculation and analysis of the results are performed. The article can be used as a base material for further research of methods for reducing inductive resistance and improving the efficiency of aircraft of different configurations.
