Wind-Tunnel Investigation of Plain Ailerons for a Wing with a Full-Span Flap Consisting of an Inboard Fowler and an Outboard Retractable Split Flap

Abstract

Tests were conducted on a NACA 23012 wing with full-span combinations of fowler and split-type flaps to determine their control characteristics. Data for roll, yaw, and hinge moments were obtained at air speeds of 40 mph and at several angles of attack and flap deflections. Results indicated that a plain sealed aileron with internal balance will provide lateral control for planes equipped with full-span combinations of slotted and split-type flaps.
