Abstract :This article describes the performance benefits of variable winglet configurations. The primary variables investigated involved varying the winglet twist and dihedral angle of a comparable Airbus A330-300 wing structure. Numerical studies have been carried out in AVL insert ignore into journalissuearticles values(Athena Vortex Lattice Method);. In order to illustrate the aerodynamic benefits of morphing winglet concepts for different flight regimes, values of twist insert ignore into journalissuearticles values(-10°< θ <10°, in steps of ±2.5°); and values of dihedral insert ignore into journalissuearticles values(-90°< θ <90°, in steps of ±15°); were designed and numerically investigated. The results obtained from this work indicate that by carefully adjusting morphing winglets on air vehicles insert ignore into journalissuearticles values(Airbus A330-300);, the aerodynamic performance benefits could be achieved.
