NACA-WR-L-441
Wind-tunnel investigation of an NACA 23012 airfoil with two sizes of balanced split flap
Year: 1940
Abstract: An investigation has been made in the NACA 7- by 10- foot wind tunnel of an NACA 23012 airfoil with a 15-percent-chord and a 25-percent-chord balanced spilt flap of the Clark Y profile. The investigation wag made to determine the aerodynamic section characteristics of the airfoil as affected by the size, nose location, and deflection of the complete aerodynamic section characteristics were determined for several nose locations of each flap and are presented for four typical locations for each flap. A comparison of the drag and lift characteristics is made with two other medium-chord flaps previously investigated.
