Abstract


An experimental wind tunnel investigation was undertaken to determine the effect of Gurney flap on the aerodynamic characteristics of Clark y-14 airfoil wing at a Reynolds number of 2.1x105. The heights of plain flap change from (1.19% C) to (5.60% C).In addition the (5.60% C) was serrated to different heights and configurations. The Gurney flap improve performance of Clark y-14 airfoil wing compare with clean wing, the results show that the most beneficial Gurney flap is (1.19% C) which increase maximum lift to drag ratio to (5.31%) compared with clean wing. The serrated Gurney flap tend to be increase lift to drag ratio significantly, the rectangular serrated Gurney flap provides the best performance among the serrated Gurney flaps by improve lift to drag ratio to (42.8%).

Author Keywords: Rectangular wing, Gurney flap, lift enhancement, wind tunnel tests, lift to drag ratio.
