Flapping wing devices for Mars exploration: Preliminary results from a novel flapping wing mechanism

The need to maximize the exploration of Mars by covering a larger area of terrain could be realized by exploiting aerial vehicles. A comparative analysis of varying flight technologies for use on Mars identified the use of a novel flapping wing approach as a potential for a more capable flight mode on Mars. A unique patented mechanism, which can move wings in a kinematically similar manner as insects or hummingbirds, termed 'RotaFlap', was investigated through the integration, design and construction of various prototypes. The RotaFlap kinematics was characterized to understand the pertinent parameters. A host of variations have been identified, previously and in this study, and a subset of these were tested within the scope of this study. A preliminary characterization of the force production, especially the vertical lift coefficients, was completed. It was concluded that this mechanism produces vertical lift coefficients similar to insect and hummingbird flight.
