Large-Area Electrostatic-Valved Skins for Adaptive Flow Control on Ornithopter Wings

Year: 2002

Type: conference-paper

Abstract: This paper presents the design and fabrication of wafer-sized parylene skins with integrated electrostatic valves used for realtime adaptive airflow control on ornithopter wings.For the first time, we report successful aerodynamic control in both lift and thrust using MEMS active-valved wings.By distributing electrostatic valves, the pressure distribution on the wings can be controlled during flapping.The valved wings were tested in a lowspeed wind tunnel to measure influence on aerodynamic performance.It was found the lift and thrust generated by the wings in flapping motion can increase by 18% when the valves are actuated.
