Date received by school : Effects of a Gurney Flap on a Single Element Airfoil Christophe Bergeron-Boisclair Oxford Brookes University ABSTRACT MAIN SECTION The effects of gurney flaps were studied on a 1 wing span NACA6713 airfoil profile at the speed of 40/. In this investigation different gurney flap height (0 to 35) has been simulated with a wide range of angle of attack. Based on the results, gurney flaps increase the lift generated even up to a 13% gain. Increasing the height always increases lift but reduces efficiency. Furthermore, gurney flap still increases the lift in post-stall conditions by increasing the pressure on the upper side of the wing. For the research, to achieve results, the configurations will be tested by CFD (Star-CCM+). The airfoil profile chosen for this research is NACA6713. This is a cambered profile with a chord
