Estimation of Incremental Pitching Moments Due to Trailing-Edge Flaps on Swept and Triangular Wings

Harry A James, Lynn W Hunton

Abstract

Report presenting a method by which incremental pitching moments can be estimated for swept and triangular wings with arbitrary types of trailing-edge high-lift flaps. Span-loading theory is combined with two-dimensional airfoil data adjusted for the effects of sweep. Application of the method is demonstrated for 58 cases covering various types of flaps on wings with a wide range of sweep, aspect ratio, and taper ratio.
