Experiments giving hinge moment and lift on a NACA 0015 aerofoil fitted with a 40 per cent control, with especial reference to effect of curvature of control surface

Abstract

To add to the available data regarding lift and hinge moment on a control, and to test further the ideas developed in R. & M. 20O8, with especial reference to the effect of curvature of control surface. Measurement of lift and hinge moment on a two-dimensional aerofoil (section NACA 0015, chord 18 in.) fitted with a 40 per cent control (radius-nose).
