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 (Athena Vortex Lattice Method). In order to illustrate the aerodynamic benefits of morphing winglet concepts for different flight regimes, values of twist (-10°< θ <10°, in steps of ±2.5°) and values of dihedral (-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 (Airbus A330-300), the aerodynamic performance benefits could be achieved.
