Pressure Distribution Over a Plug-Type Spoiler-Slot Aileron on a Tapered Wing with Full-Span Slotted Flaps

John G Lowry, Thomas R Turner

Abstract

From Summary: A pressure-distribution investigation was made in the Langley 7- by 10-foot tunnel of a plug-type spoiler-slot aileron on a semispan tapered-wing model of a typical fighter airplane equipped with full-span slotted flaps. The results of the investigation indicate peak pressure on a plug-type spoiler-slot aileron that may result in a compressibility shock on the plug aileron at high speed. The maximum loads on the plug aileron occurred in the high-speed condition for maximum up aileron deflection.
