The impact of winglets of different size on the actual flight shape of the wing is investigated. Three configurations are addressed: the standard winglet, a large winglet, and the clean wing for reference. The purpose of the investigation is to gain understanding of the aeroelastic behaviour of an integrated flexible wing and winglet combination. Verification of methods for the prediction of the actual flight shape of the wing at various cruise conditions is performed by comparison with optical measurements of the in-flight deformations. It is concluded that current aeroelastic prediction methods, based on Navier-Stokes flow modelling, provide a suitable analysis tool for baseline and trade-off studies of flexible aircraft.
