The winglet effect on vibration in aircraft wings

Aircraft wings are under the influence of aerodynamic forces during flight and these forces cause vibrations. Reducing vibrations to acceptable values makes a positive contribution to the flight characteristics of aircraft. Therefore, vibration analysis of aircraft wings in both design and production stages is of great importance in engineering studies. In this thesis, an aircraft wing prototype with NACA 2412 profile and four different aileron designs and PLA filament material were produced. Productions were carried out with the help of 3D printer. Vibration values were measured for different types of fins with the wind tunnel. It has been determined that different types of fins affect aircraft wing vibrations. The use of fins reduced the amplitude of the vibration caused by the motor. NACA 2412 wing profile was compared with Pulse MTC and Abaqus software to obtain natural frequency and mode shapes. A concordance between experimental and numerical study was observed.
