Computational Analysis Of Slotted Wing Tips At Low Reynolds Number

ABSTRACT The aerodynamic characteristics of a simple rectangular wing of NACA0012 airfoil with slotted tips which is mostly used in MAVs and UAVs at low Reynolds number has been analyzed using FLUENT. UAVs fly at low Re and have smaller dimensions low AR and fly in similar environmental conditions as compared to biological fliers of similar weight. In the present study wings with slotted tips are modeled and analyzed with and without slots at different angles of attack for Reynolds number regimes of 300000. It is observed that the drag coefficient has been decreased consistently with small increment in lift to drag ratio. The current analysis is done for 8101214 and 16 degree of angle of attack and results seems to be good at 8 degree angle of attack
