Abstract
The work concerned represents a winglet design inspired by birds with slotted wings. Slotted wings are known to exhibit optimum characteristics in terms of reducing the generation of vortices, enhancing roll stability, countering induced drag, and enhancing lift and stall characteristics. Light is shed on these parameters while designing the model. Key aerodynamic parameters are also highlighted. The model is further simulated to obtain the change in the characteristics of multiple aerodynamic parameters, concerned with wingtips and winglets. The main area of concern is the reduction in the values of drag, specifically the induced drag, as it is a major contributing factor in a subsonic aircraft’s overall drag generation. The work included in this paper is a study on an albatross wing to improve its maneuverability and its aerodynamic characteristics so that it can be used in a bionic UAV with better endurance and roll control. These slots can later be made to actuate at different angles. This study acts as a base for further research.
