Wind-tunnel investigation of a spoiler-slot aileron on an NACA 23012 airfoil with a full-span Fowler flap

Bartholomew S Spano

Abstract

Report presenting an investigation of a spoiler-slot aileron on an NACA 23012 airfoil with a full-span 30-percent-chord Fowler flap. The static rolling, yawing, and hinge moments were determined for several angles of attack and flap deflections. The ineffective region could be eliminated by a provision in the aileron linkage that would automatically uprig the ailerons as the flap is deflected.
