Wind-Tunnel Investigation of Control-Surface Characteristics of Plain and Balanced Flaps With Several Trailing-Edge Angles on an NACA 0009 Tapered Semispan Wing

Abstract

Lift and hinge-moment parameter values as calculated by existing methods from two-dimensional data are investigated. Differences between measured values of lift and hinge-moment parameters and values calculated from two-dimensional data were no greater than differences between values for wings of same aspect ratio but with different chord distribution. Effects of overhang, gap, and trailing-edge angle on parameters are similar to effects of two-dimensional models. Interference between bevel overhang are indicated.
