Abstract: Administrative common aeronautics offices are pushing airplane producers and administrators to improve airplane proficiency by lessening fuel utilization, cutting carbon dioxide CO2 and nitrogen oxide NOx emanations, and bringing down the apparent outer commotion. The above problems can’t be rectified fully but we can ably minimize the fuel consumption, so automatically carbon dioxide and nitrogen oxide will be reduced. The best solution is to decrease the lift induced drag in the way of changing the cant angle of the winglet. So, we design a straight wing and with different sweep angle using the Catia V5 after creating these wings and we go to the CFD for analyzing the wings at certain condition. Using Winglet, the aerodynamic performance will be investigated in Low Reynolds No regime. Winglet configuration will be varied in terms of sweep back angle and cant angle. Best configuration will be optimized.
