- Summary:
- An investigation was made in the N.A.C.A. 7- by 10-foot wind tunnel of a large-chord N.A.C.A. 23030 airfoil with a 40- and a 25.66-percent-chord slotted flap to determine the section aerodynamic characteristics of the airfoil as affected by flap chord, slot shape, flap position, and flap deflections. The flap positions for maximum lift, the positions for minimum drag at moderate and high lift coefficients, and the complete section aerodynamic characteristics of selected optimum arrangements are given. Envelope polars of various flap arrangements are included. The relative merits of slotted flaps of different chords on the N.A.C.A. 23030 airfoil are discussed, and a comparison is made of each flap size with a corresponding flap size on the N.A.C.A. 23021 and 23012 airfoils.
