This work analyses the aerodynamic characteristics of multi-winglets applied to low speed aircrafts. This device has demonstrated a potential of improving the aerodynamic efficiency by reducing the induced drag. Experimental investigations were conducted for a wing-body half model with six different multi-winglet configurations.
