Abstract

An assessment study of wing tip devices at low speed is described. Designed at cruise, the device provides poor low speed performance due to large regions of flow separation. Both airfoil redesign and the usage of moving parts on the leading edge are investigated to gain the flow behaviour. This study was done in two stages using a clean configuration at low speed and furthermore a take-off geometry at high-lift. Both techniques provide benefitail impact on the aerodynamic behaviour at low speed regime
