description abstractA wind-tunnel investigation has been made of the low-speed lateral. control characteristics of a tapered, low-hag semispan model equip with 20-percent-chord sealed ailerons having spans of 0.954, 0.583, and 0.294 percent of a full-span aileron, each with &ailing-edge angles of 6°, 14°, and 25°. Th9 investigation also included tests with the ailerons unsealed, simulating symmetrical lift-flap configurations having spans of 0.954 and 0.66° percent of a full-span flap. The aileron hinge-moments and pressures over the aileron seal were determined for each of the nine aileron configurations in addition to the Usual lift and lateral-control coefficients.
The results of this investigation, in general, indicated that the existing theoretical method for predicting the slope of the curve of rolling-moment coefficient with aileron deflection clsa  for various
spans of aileron gave satisfactory agreement with the experimental results for ailerons having trailing-edge angles of 6° and 14°. The agreement between the experimental and theoretical values of Clsa  was poor, however, for the ailerons with a trailing-edge angle of 25°.
