Aerodynamic Optimization of a Morphing Winglet Design

Abstract

In the present study, a CFD is used to investigate the flow around an isolated wing equipped by a morphing winglet. In order to obtain initial estimates of lift and drag coefficients with flow velocity of 20 meters per second a various angles of attack, several cases of winglets were tested according to different dihedral angles. The model of k-ω SST turbulence is used for the investigation of the complex flow around the morphing winglet. The present results shown a good agreement with the literature data.
