Abstract

 

The purpose of this paper is designing an efficient winglet in wings of Micro Aerial Vehicles (MAV) for low speed Reynolds. Winglets are designed to reduce induced drag generated by downwash and to reduce the strength of tip vortices. The wing is made of FX60100 aerofoil for the MAV studied. A comparison is made between the aerodynamics characteristics of the wing with and without winglets. Different types of winglet are examined. The designed winglet has enhanced almost 20 percent on lift to drag ratio.
