日期:2017 年 06 月 30 日 ( 星期五)
Time:3:00 pm – 4:00 pm
Venue:EF305

Abstract:

Insect and bird size drones – micro air vehicles (MAV) that can perform autonomous flight in natural and man-made environment are now an active and well-integrated research area. MAVs normally operate at a low speed in a Reynolds number regime of 104 - 105 or lower, in which most flying animals of insects, birds and bats fly, and encounter unconventional challenges in generating sufficient aerodynamic forces to stay airborne and in controlling flight autonomy to achieve complex manoeuvres. Flying insects that power and control flight by flapping wings, are capable of sophisticated aerodynamic force production and precise, agile manoeuvring, through an integrated system consisting of wings to generate aerodynamic force, muscles to move the wings, and a control system to modulate power output from the muscles. In this lecture, I will overview the state of the art of biomechanics in bioinspired flight systems in terms of flapping and flexible wing aerodynamics, flight dynamics and stability, passive and active mechanisms in stabilization and control, as well as flapping flight in unsteady environments. I will further highlight recent advances in biomimetics of flapping-wing MAVs with a specific focus on insect-inspired wing design and fabrication, as well as sensing systems.

From 2000 to 2003, he was a senior research scientist in the Institute of Physical and Chemical Research (RIKEN) in Wako, Saitam, a leading national institute in Japan. From 1998 to 2000 he was an assistant professor in Nagoya Institute of Technology. From 1993 to 1998 he was a research scientist in Japan Science and Technology Agency (JST). From 1992 to 1993 he was a research scientist in Ship Research Institute, Japan. He received a BS degree in 1985 from Dalian University of Technology in China. He went to Yokohama National University in 1986, and received M.S.E. and Ph.D. degrees, both in fluid engineering, in 1989 and in 1992, respectively. He is the author and a co-author of more than 450 papers in refereed journals and national and international conferences, dealing with computational and modeling issues related to computational and modeling concepts for fluid dynamics, heat transfer, free surface and moving boundaries, parallel computing, insect flight, fish swimming, unsteady aerodynamics at low Reynolds number, fluid-structure interaction, micro air vehicles, biomimetics, bio-inspired engineering, physiological fluid dynamics, computational biomechanics, and multi-scale & multi-physics modeling of the cardiovascular system, and biomedical engineering.

He is the Editor-in-Chief of Journal of Aero Aqua Biomechanisms, an associate Editor-in-Cheif of Acta Mechanica Sinica and on the editorial board of Biomimetics & Bioinspiration and Journal of Bionics Engineering. He has given more than 75 seminars and invited/keynote lectures in many institutions and conferences, and is a Guest Chief Scientist of RIKEN (The Institute of Physical and Chemical Research), a chair professor at Shanghai Jiao Tong University of Chinese government’s “Thousands Talent Program” and Chang Jiang Scholars Program of Chinese Ministry of Education, a Guest Professor of Chinese Academy of Sciences’ Graduate School, China Science and Technology University (China), and a visiting professor of The Hong Kong University of Science and Technology (HKUST). His professional views have been quoted in several news media, including the NHK, the AFP, the Thomson Reuter, the Yomiuri, and the Science Channel Network of the JST (Japan Science and Technology Agency).
