What is High-Lift Airfoil Investigation about?
This document summarizes an investigation of two symmetrical circular-arc airfoils equipped with leading-edge and trailing-edge high-lift devices. The high-lift devices tested included a 0.20-chord plain trailing-edge flap, a 0.15-chord drooped-nose flap, and a 0.10-chord leading-edge extensible flap. Maximum section lift coefficients of 1.95 and 2.03 were obtained for the 6% and 10% thick airfoils, respectively, at a Reynolds number of 6 x 105 using the optimum combination of drooped-nose and plain flaps.
