航空学院青年学术论坛第一〇四讲(六场报告)
2018-05-17 09:26   审核人:

报 告 人:美国杜克大学Earl H. Dowell院士

邀 请 人:史爱明

报告一

时间:5月23日9:30~地点:航空楼A706

1. Experimental Aeroelastic Models: Design and Wind Tunnel Testing for Correlation with new Theory

This is a summary of aeroelatic experiments done at Duke University over the last several years including correlation with theory and computations.

报告二

时间:5月23日14:30~地点:西馆XA103

2. Nonlinear Stiffness, Inertial and Damping Effects in a Cantilevered Beam

Cantilevered beams and plates canundergo large nonlinear oscillations on the order of the length. This can and usually does create both stiffness and inertial nonlinear effects and may induce nonlinear damping effects as well.

报告三

时间:5月24日14:30~地点:航空楼A706

3. Recent Advances and Future Directions in Nonlinear Aeroelasticity

This lecture provides a broad overview of the subject of Nonlinear Aeroelasticity

报告四

时间:5月25日9:00~地点:国际会议中心第一会议室

4. Stability of Rotorcraft for Interplanetary Space Flight

One solar sail concept for deep space exploration is a large span membrane rotor blades powered by solar pressure. This pressure can also lead to dynamic instabilities.

报告五

时间:5月25日10:50~地点:国际会议中心第一会议室

5. Future of Engineering Education

Lessons learned and current challenges for engineering education in the United States are discussed.

报告六

时间:5月25日14:30~地点:航空楼A706

6. Hypersonic Fluid-Structure Interaction

Renewed interest in hypersonic flow vehicles has generated interest in fluid structure interactions (aeroelasticity).

Dr. Dowell is an elected member of the National Academy of Engineering, an Honorary Fellow of the American Institute of Aeronautics and Astronautics (AIAA) and a Fellow of the American Academy of Mechanics and the American Society of Mechanical Engineers. He has also served as Vice President for Publications and member of the Executive Committee of the Board of Directors of the AIAA; as a member of the United States Air Force Scientific Advisory Board; the Air Force Studies Board, the Aerospace Science and Engineering Board and the Board on Army Science and Technology of the National Academies; the AGARD (NATO) advisory panel for aerospace engineering, as President of the American Academy of Mechanics, as Chair of the US National Committee on Theoretical and Applied Mechanics and as Chairman of the National Council of Deans of Engineering. From the AIAA he has received the Structure, Structural Dynamics and Materials Award, the Von Karman Lectureship the Crichlow Trust Prize and the Reed Aeronautics Award; from the ASME he has received the Spirit of St. Louis Medal, the Den Hartog Award and Lyapunov Medal; and he has also received the Guggenheim Medal which is awarded jointly by the AIAA, ASME, AHS and SAE.

He has served on the boards of visitors of several universities and is a consultant to government, industry and universities in science and technology policy and engineering education as well as on the topics of his research.

Dr. Dowell research ranges over the topics of aeroelasticity, nonsteady aerodynamics, nonlinear dynamics and structures. In addition to being author of over three hundred research articles, Dr. Dowell is the author or co-author of four books, "Aeroelasticity of Plates and Shells", "A Modern Course in Aeroelasticity", "Studies in Nonlinear Aeroelasticity" and “Dynamics of Very High Dimensional Systems”. His teaching spans the disciplines of acoustics, aerodynamics, dynamics and structures.

Dr. Dowell received his B.S. degree from the University of Illinois and his S.M. and Sc.D. degrees from the Massachusetts Institute of Technology. Before coming to Duke as Dean of the School of Engineering, serving from 1983-1999, he taught at M.I.T. and Princeton. He has also worked with the Boeing Company.
