Results of investigation conducted in NACA 4 by 6-ft vertical wind tunnel to determine air loads on 23021 airfoil in combination with 25.66% chord slotted flap and 20% chord split flap; pressures were measured on both upper and lower surfaces of main airfoil and flaps for several angles of attack and at several flap settings; data presented as pressure diagrams and graphs.
