Effects of Gurney Flaps on an Annular Wing

Journal of Aircraft, 2009
F OR a constrained wing span, nonplanar wings exhibit significant aerodynamic benefits. These are generally indicated through increased lift curve slopes and reduced drag due to lift. These benefits are accrued through thewing capturing a larger volume of air to generate the lift impulse, and consequently the downwash at a point is reduced [1].

Gurney Flaps on Slender and Nonslender Delta Wings

Journal of Aircraft, 2010
*† ‡ A parametric low-speed wind tunnel study has been undertaken of the effect of Gurney flaps on the aerodynamic characteristics of slender and non-slender delta wings with sweep angles of 40°, 60° and 70°. In contrast to published data, no fundamental difference in behaviour with sweep angle was found.

Additional Aerodynamic Features of Wing-Gurney Flap Flows

Journal of Aircraft, 2006
An extension of the existing explanation of the flow mechanisms characteristic of the wing-Gurney flap flow has been proposed. Based on the Helmholtz vortex theory, it has been postulated at the onset of the present study that, in addition to the spanwise vortices, as predicted by a commonly accepted flow hypothesis one or more pairs of streamwise ...
