<![CDATA[Bird strikes are a threat that affects the structural integrity of aircraft, and unmanned aerial vehicles (UAVs) are no exception. Bird strikes cause changes to the shape of the wing, including the airfoil, which affects the aerodynamic performance and flight safety of the aircraft. Manufacturers must conduct various tests before a UAV is authorized for commercial use, one of which is structural strength. Numerical simulation of bird strikes is an important part of UAV component design to reduce testing costs. This study aims to analyze the structural response and aerodynamic performance of the UAV airfoil caused by bird strikes. The deformed wing geometry for computational fluid dynamics analysis was obtained from bird strike simulations using the finite element method and the smoothed particle hydrodynamics bird model. The deformed wing geometry is analyzed using the computational fluid dynamic software to obtain the pressure distribution around the airfoil, pressure coefficient, lift, and drag. The results show that the deformed airfoil's leading edge alone experiences positive high pressure. With a change in angle of attack, the deformed wing's lift coefficient is lower than the undeformed wing's. In contrast to the lift coefficient, with a change in angle of attack, the deformed wing's drag coefficient is higher than the undeformed wing's because the pressure distribution is disrupted.]]>
