ABSTRACT
During the flight, many models UAV [1] have been destroyed. Especially, many UAV were
destroyed on the surface of the wing. This paper, based on aerodynamic elastic principles, presents causes
of the destroyed phenomenon of UAV's profile. Also, the paper presents the results obtained when conducting
durable fiber composite UAV model in which the wings are reinforced by hard steel of average carbon
intensity (carbon 0:25 - 0.6% )[1] in changing weather conditions with 2 level, 3 level, 4 level and 6 level
windy. The calculation results are simulated in Ansys CFX.
Keywords: Unmanned Aerial Vehicle, destroyed phenomenon, endurance test, simulation,
aerodynamic.
