Dr. Zhu is a Professor and Tier 1 York Research Chair in Space Technology in the Department of Mechanical Engineering at York University. He received B.Eng, M.Eng and Ph.D. degrees in engineering mechanics from Shanghai Jiao Tong University, Shanghai, China. He also received masters in robot control from University of Waterloo and doctorate in mechanical engineering from University of Toronto. He held positions of Research Associate at University of Toronto in 1993-1995 and senior stress and certified welding engineer at Curtiss-Wright Indal Technologies in 1995-2006. He joined the Department of Earth and Space Science and Engineering at York in 2006 and then the Department of Mechanical Engineering in 2016. He has authored more than 300 articles and his current research interests include dynamics and control of  tethered space system and space robotics, space debris removal, and small satellite technology.  


Dr. Zhu is the recipient of 2019 Ontario Professional Engineers Awards: Engineering Medal - Research and Development. He is the College Member of Royal Society of Canada, the Fellows of Canadian Academy of Canada, Engineering Institute of Canada, CSME and ASME; the Associate Fellow of American Institute of Aeronautics and Astronautics, the Academician of International Academy of Astronautics, Senior Member of IEEE, and licensed Professional Engineer.


Synopsis of the Topic:  In this presentation you will learn about the following: Space tether systems are spacecraft connected by long cables. They can be used for propulsion, momentum exchange, energy harvest, space transportation, and spacecraft formation flight that maintains the relative positions of a large dispersed satellite/spacecraft sensor system. Typical examples are space elevators, skyhooks, electrodynamic tethers, electric solar wind sail and space net. Depending on the mission objectives and altitude, spaceflight using space tether systems is significantly less expensive than spaceflight using rocket engines in theory. The seminar will provide an overview of space tether systems, main techniques and types, mission history of space tether systems, and future application in space exploration.
