No. 2, Ⅱ1/2-ft Wind-Tunnel Tests of a Small Span, Small Chord Double Aileron for Use as a Lateral Control on a High-Lift Aircraft

摘要

Tests were made on a 1/2.25 scale model of a half wing of the Master. The span of the aileron was 0 • 22s and the chords were 0-2c and 0.15c;the aileron was fitted with a balance tab of 0-05c chord (see Table 1 and Fig. 1). Measurements were made of the hinge moments, lift increments (from which the rolling moments were deduced) and the pressures in the aileron gaps just above and below the seals. The latter were required for estimating the effect of internal shrouded nose (or pressure) balances. Tests were also made of the effect on the hinge and rolling moments of a small spoiler situated just aft of the front aileron vent;the spoiler was assumed to emerge on the lower surface of the down-going aileron and on the upper surface of the up-going aileron.
