Abstract
The work is devoted to the study of aerodynamic characteristics of the WIG original layout and the assessment of influence of its geometric parameters on the aerodynamic characteristics. A brief overview of the history of synthesis of the investigated WIG scheme is presented. The aerodynamic layout is made according to the "tandem" scheme of two wings and a high-mounted stabilizer. The influence of kinematic flight parameters (angle of attack and distance to the underlying surface), deflection angles of aerodynamic surfaces (flaps and steering surfaces), the relative position of the wings, the presence and parameters of end washers and winglets on the WIG aerodynamic characteristics is investigated. The results of the work allow us to conclude that the deflection angles of aerodynamic surfaces have a significant effect on the values of aerodynamic coefficients and the value of aerodynamic quality. These effects can be used to control the WIG, improve or provide a number of flight characteristics. The most preferred parameters of the aerodynamic layout are evaluated in terms of ensuring the highest aerodynamic quality. A number of defining features of the flow around the proposed WIG scheme and its elements are identified and demonstrated in the work. The potential positive properties of the layout are highlighted, which can significantly affect the feasibility and effectiveness of the WIG as a design object
