The Gurney flap (or wickerbill) is a small tab projecting from the trailing edge of a wing. ... Common applications occur in auto racing, helicopter horizontal stabilizers, and aircraft where high lift is essential, such as banner-towing airplanes. It is named for its inventor and developer, American race car driver Dan Gurney. See more The Gurney flap (or wickerbill) is a small tab projecting from the trailing edge of a wing. Typically it is set at a right angle to the pressure-side surface of the airfoil and projects 1% to 2% of the wing chord. This trailing edge device … See more The original application, pioneered by American automobile racing icon Dan Gurney (who was challenged to do so by fellow American racer Bobby Unser), was a right-angle piece of sheet metal, rigidly fixed to the top trailing edge of the rear wing on … See more Gurney flaps have found wide application on helicopter horizontal stabilizers, because they operate over a very wide range of both positive and negative angles of attack. At one … See more The Gurney flap increases the maximum lift coefficient (CL,max), decreases the angle of attack for zero lift (α0), and increases the nosedown pitching moment (CM), which is consistent with an increase in camber of the airfoil.
