When considering smaller scale UAV’s there is not a lot available that could survey large areas quickly, stealthy, and with a considerable range. Owls have an interesting trait that is not found in most avian species; leading-edge serrations. These serrations give owls the ability to fly silently and steadily without sacrificing maneuverability. The focus of the research was to design leading-edge serrations that would improve the flight performance of a Styrofoam glider. Previous studies defined serrations by the inclination angle, tip-displacement angle, and the length of the serration in the x-y plane. Using these parameters, a serration mold was computer modeled and 3D printed from a resin material. Silicone was used to cast the mold, allowing flexible serrations to be created. The serrations were fitted onto the leading-edge of a Styrofoam glider which was used for flight testing. Flight test between serrated and non-serrated leading-edge gliders are presented and compared.
