This paper includes an experimental study of the effect of irregular vibrations (random vibration) resulting from dynamic aerodynamic load or the turbulent winds of the unmanned aerial vehicle (UAV) wing, as well as finding aerodynamic forces affecting the wing.
The objective of this study is to determine the concentration areas of the force in which the failure occurs and to know the behavior of random vibration and its effect on the wing structure.
The wing was constructed and manufactured with suitable dimensions and then the wing was installed inside the wind tunnel of the test.
The wing has been tested at five angles of attack (0º, 5º, 10º, 15º and 20º) and certain wind velocities.
Through the sensors and associated signal analyzers, the relationship was obtained between acceleration and frequency acceleration of specific points on the wing surface and the forces of drag, lift and torque were calculated.
The results show, it was found that the greatest value of the forces is concentrated in the area near the edge fixed at the wing root especially in the large attack angles.
Also it was concluded that the drag and lift forces and torque torsional wing increases proportional to the increase in wind velocity and angle of attack
