Abstract

Hummingbirds and some insects exhibit a Figure-8 motion, which allows them to undergo variety of maneuvers including hovering. It is therefore desirable to have flapping wing miniature air vehicles (FWMAV) that can replicate this unique wing motion. In this research, a design of a flapping wing for FWMAV that can mimic Figure-8 motion using a spherical four bar mechanism is presented. To produce Figure-8 motion, the wing is attached to the coupler point of the spherical four bar mechanism and driven by a DC servo motor. For verification of the design, a prototype of the wing and mechanism is fabricated to determine whether the design objectives are met. Additionally, experimental testing is conducted to determine the feasibility of this design with the wing driven at speeds ranging from 2.5 to 12.25 Hz. To determine the aerodynamic coefficients the wing experiences during the Figure-8 cycle, wind tunnel experimentation is conducted. The results show good correlation between the model and experimental testing.
