Wind-tunnel investigation of control-surface characteristics I - effect of gap on the aerodynamic characteristics of an NACA 0009 airfoil with a 30-percent-chord plain flap
Year: 1941
Abstract: Tests have bee; made to determine the effect of a gap at the flap nose upon the aerodynamic section characteristics of an NACA 0009 airfoil with a plain flap and tab. The results are presented in the form of airfoil and flap section characteristics for several flap deflections, tab deflections, and for four sizes of gap.
The results shoved that a plain flap with a sealed gap was best because it gave maximum effectiveness with minimum stick forces and because it was the most effective in delaying separation over the flap surface.
