Abstract

The aim of this work is to determine the Aerodynamic properties of the corrugated dragonfly airfoil in comparison to the traditional smooth NACA 2.5411 airfoil. A simplified dragonfly airfoil is analysed in the current work, at low speeds. A 3D printed model is tested using Six Component strain gauge and the results are compared with NACA 25411 airfoil. Aerodynamic performance is evaluated at low Reynolds number to associate the results with the regular section. In order to streamline the results both experimental and numerical work is carried over the model at different wind speeds and wind angles. Data obtained provides a valuable insight to the physics of the model which showed a completely nonlinear behaviour resulting in positive aerodynamic forces.
