Development of a biomimicry flapping wing Micro Air Vehicle
Insect flight is known to be quite different from birds and other conventional flying machines. The fast reciprocating motion of the insect wings creates vortices, which subsequently produces lift. The unsteady aerodynamics allows lift to be produced more efficiently at low Reynolds number compared to quasi-steady aerodynamics, which is usually applied on fixed-wings and rotary wings. This advantage suggests that flapping wings is a better option in the effort to pursue micro scale flying machines, but it brings about challenges such as hardware miniaturization, and fabrication techniques. Furthermore, the small inertia of the flying machines makes them sensitive to wind and gust. This talk focuses on the multiple aspects of the development, the challenges encountered, and the most recent progress made on a double clap-and-fling insect-inspired flapping wing micro-air-vehicle. The aspects including flapping mechanism design, wing design, fabrication, and flight control and stabilization. The flying vehicle weighs about 27 gram, actively stabilized, and capable of carrying a camera payload.
About the speakers:
Chan Woei Leong, Ph. D. is Research Scientist at the Temasek Laboratories of the National University of Singapore. Dr. Chan received Bachelor degree from Universiti Sains Malaysia in Aerospace Engineering, and his Master degree and Ph.D. from the National Cheng Kung University, Taiwan in Aeronautical Engineering. He had been involved in fixed-wing UAV research during his post-graduate study and his achievement includes the development of a fully autonomous, fully customized fixed-wing UAV and a demonstration of 92km cross-sea flight in 2009. He then joined the SIM University in Singapore as a Research Associate where he started his involvement in flapping wing micro-air-vehicle research in 2011. He continues to pursue insect inspired flapping wing MAV design after he joined the National University of Singapore. His current research focus is on the autonomy and mechanics of a 27-gram flapping wing MAV. Dr. Chan is the recipient of the 2016 Inspiring Research Mentor Award from the NUS High School of Mathematics and Science, and his undergraduate student team had won a few awards in local and regional competitions, including first place in the flapping wing category of the 2017 Taiwan Innovative Unmanned Aircraft Design Competition, and first place in the unconventional category of 2018 Singapore mazing Flying Machine Competition.
