Wind-Tunnel Investigations of the Characteristics of Blunt-Nose Ailerons on a Tapered Wing

Abstract

Characteristics are determined for various modifications of 0.155-chord blunt-nose aileron on semispan model of tapered flighter plane wing. Ailerons with 40 percent nose balance reduces high-speed stick forces. Increased balance chord increases effectiveness and reduces high-speed stick forces. Increased balance chord increases effectiveness and reduces adverse effects of gap at aileron hose. Increase of nose radii increased negative slope of curve hinge-movement coefficient plotted against deflection. Extended deflection range decreased aileron effectiveness for small deflections but increased it at large deflections. Peak pressures at noses of ailerons are relatively high at moderate deflections.
