WebJan 3, 2024 · The purpose of this paper is to mount Gurney flaps at the trailing edges of the canards and investigate their influence on aerodynamic characteristics of a simplified canard-configuration aircraft model.,A force measurement experiment was conducted in a low-speed wind tunnel. Hence, the height and shape effects of the Gurney flaps on the … WebThe Gurney flap also causes the stall to occur earlier. Blade element momentum (BEM) method based on linear aerodynamics is used to assess the effect of the Gurney flap installation on a generic three-blade small HAWT. It is seen that Gurney flaps of 1.5c% and 2c% noticeably increase the optimal power coefficient of the HAWT.
