▎ 摘　　要

NOVELTY - The airfoil (1) has a leading edge (10), which is the part where the fluid first meets the front edge, and a trailing edge (20) where the fluid entering from the leading edge leaves when wing structures of aircraft, micro and unmanned aerial vehicles and wind turbines used in the aviation and energy sector are exposed to low speeds or when it is exposed to low speeds. The upper gap portion (60) located on the suction surface and a flexible plate (70) made of pure silicon or silicon-based material reinforced with reinforcing composite materials such as glass, carbon, graphene is positioned in the upper gap portion located on the suction surface. USE - Airfoil for use in aircraft, propeller and turbine structures. ADVANTAGE - The airfoil provides increasing the aerodynamic performance of wing structures with adding flexibility using silicone-based flexible material to the wing/blade structures of aircraft, micro and unmanned aerial vehicles and wind/gas/steam turbine systems used in the sectors serving in the field of energy and aviation. DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of the airfoil. Airfoil (1) Leading edge (10) Trailing edge (20) Upper gap portion (60) Flexible plate (70)
