Book excerpt: Summary: An investigation has been made in two-dimensional flow to determine the effect of leakage past the aileron nose on the aerodynamic characteristics of ailerons. Plain and internally balanced ailerons of 0.20 airfoil chord were tested on an NACA 66(215)-216, a-1.0 airfoil. The effects of amount and type of leakage, aileron contour, and Mach number and Reynolds number were investigated. The results of the tests indicated that a small amount of leakage area changed the pressure distributions over the plain and internally balanced ailerons markedly. This change generally resulted in negative increments in the lift and hinge-moment parameters c [subscript l] subscript [delta], c [subscript h] subscript [alpha], and c [subscript h] subscript [delta]. A further increase in the leakage area produced smaller changes in these parameters for the internally balanced aileron.
