Abstract:

The focus of this Year II Directors Research Initiative resulted in design improvements and extended experimental capability for the next design iteration of millimeter-scale flapping wings. Three different design approaches intended to produce significant pitching motion through a flap stroke are outlined while providing a more detailed description of the design methodology for one technique employing two orthogonally mounted bending actuators. Two possible approaches to designing a balance that will allow for unobtrusive measurements of the wing force production demonstrate the necessary sensitivity. A described meso-fabrication setup will reduce design cycle time. Finally, a nearly capable Reynolds number scaled testing facility, which will assist in future designs and experimental assessment, is briefly described.
