Abstract : This paper focuses on the effect of bio-mimetic leading edge protuberances known as tubercles, on MAV (Micro-Aerial Vehicle) wings. Studies were carried out to examine the effect of tubercles, inspired by the morphology of the pectoral flippers of the Humpback Whale on MAV wings with inverse Zimmerman planform of two different aspect ratios 1.00 and 2.00. Equations were developed to design the wing planform geometry, incorporating the tubercles in the form of damped sinusoidal protrusions with control parameters (amplitude, number and damping) to vary the tubercle shape. Using Star CCM+ and Ansys Fluent, the drag and lift characteristics of the models with and without tubercles were analyzed for the Re number of 1.37x10 5. It was observed that the drag and lift characteristics of the wing with tubercles shows lift enhancement in post stall region compared to wing without tubercles.
