The effects of wing geometry and aerodynamic analysis on the design of fixed-wing UAV

In order to reduce the amount of fuel used in all aircraft and to increase the useful load, designs are made in the aerodyamic structure of the body and wings. Considering this in study, aerodynamic design and analyzes were carried out on wings and UAVs for CL/CD value increasing. Aerodynamic analyzes were carried out in XFLR5 and ANSYS Fluent student, programs on the effects of fixed wing unmanned aerial vehicle design wing geometry and aerodynamic analysis. Data from both analyzes were compared. Flat (blunt) wing Altay-0020 D and vertical trapezoidal wing Altay-0020 T UAVs were designed in the SOLIDWORKS student program, with the most efficient Altay wing on the main body and the SD7037 wing on the tail fuselage. Analyzes were made in ANSYS fluent student, program at 15,5 m/s air speed and 5 different angles of attack. The Wings were designed in SOLIDWORKS, parts were removed and assembled on a 3D printer. The thesis study has been concluded with the final section, which will cover the preliminary design and analysis of the wings and the design and assembly of the unmanned aerial vehicle.
