This bird-feather-inspired porous-medium airfoil can significantly enhance lift and lift-to-drag ratio, and is capable of suppressing leading-edge separation within certain Reynolds number ranges. The present findings provide physical insights into the aerodynamic role of bird feather distributions and offer guidance for the design of biomimetic porous airfoils in low-Reynolds-number applications.
