Abstract

A new passive section approach to alleviate gust loads – the Adaptive Camber Concept – on wind turbines is introduced. The concept entails fluid-structure interaction, where flow conditions at the leading edge affect the airfoil shape. Under steady conditions, the adaptive camber airfoil de-cambers gradually with increasing angle of attack, yielding a lift curve with declined slope. The concept is investigated experimentally and numerically. Unsteady angle of attack fluctuations of various reduced frequencies are generated by means of an active grid. The adaptive camber airfoil is found to alleviate up to 60% of the fluctuating loads, while generating higher mean lift compared to a rigid airfoil.

Biography: C Tropea

Cameron Tropea graduated from the University of Toronto in Engineering Sciences, followed by a Masters degree in Mechanical Engineering (1977). He completed his Dr.-Ing. in Civil Engineering at the Technical University of Karlsruhe (1982) and his Habilitation in Fluid Mechanics at the University of Erlangen-Nürnberg (1991) where he was appointed Professor of Fluid Mechanics until 1997. This was followed by an appointment to his current chair of Fluid Mechanics and Aerodynamics at the Technische Universität Darmstadt. Currently Editor-in-Chief of the Springer journal Experiments in Fluids and past Director of the Center of Smart Interfaces (CSI) in the period 2007-2014, his research interests include Optical Measurement Techniques in Fluid Mechanics, Interfacial Transport Phenomena, Atomization and Spray Processes and Unsteady Aerodynamics. He has recently been appointed a member of the Scientific Commission of the Council of Science and Humanities in Germany.

CARRE International Research Symposium @ Medical Science Building, Auditorium
Jun 21 @ 9:00 am – Jun 22 @ 5:00 pm

The CARRE International Symposium on Aerial Robotics features experts from across Canada converging at the UTIAS Centre for Aerial Robotics Research and Education (CARRE) to discuss the future of Unmanned Aerial Vehicles.

Keynote Speakers:

  • Dario Floreano, Director, Laboratory of Intelligent Systems, EPFL, Switzerland
    Director, Swiss National Centre of Competence in Robotics

    • Prof. Dario Floreano is director of the Laboratory of Intelligent Systems at the Swiss Federal Institute of Technology Lausanne (EPFL). He is also founding director of the Swiss National Center of Competence in Robotics, which sponsors almost 60 researchers in wearable, mobile, and educational robots from 20 robotics labs across Switzerland. Prof. Floreano holds an M.A. in visual psychophysics, an M.S. in Neural Computation, and a PhD in Robotics. He held research positions at Sony Computer Science Laboratory, at Caltech/JPL, and at Harvard University. He is interested in robotics and A.I. at the convergence of biology and engineering. His research activities include aerial robotics, soft robotics, wearable robotics, and evolutionary robotics. He published more than 350 peer-reviewed articles, more than 10 patents, and 4 books on Artificial Neural Networks, Evolutionary Robotics, Bio-inspired Artificial Intelligence, and Bio-inspired Flying Robots with MIT Press and Springer Verlag. He is on the Advisory Board of Future and Emergent Technologies of the European Commission, has been a founding member of the World Economic Forum Council on robotics and smart devices, co-founder of the International Society of Artificial Life, Inc., and executive board member of the International Society for Neural Networks. He spun off two successful companies in drones (senseFly and Flyability) and a non-for-profit platform for public awareness of robotics and A.I. (RoboHub).
  • Roland Siegwart, Prof. Dr., Inst. f. Robotik u. Intell. Syst.
    • Roland Siegwart (1959) is full Professor of Autonomous Systems at ETH Zurich since July 2006 and Founding Co-Director of the Wyss Zurich. From January 2010 to December 2014 he took office as Vice President Research and Corporate Relation
      s in the Executive Board.
      He received his Diploma in Mechanical Engineering in 1983 and his Doctoral Degree in 1989 from ETH Zurich. He spent than one year as postdoctoral fellow at Stanford University. Back in Switzerland, he worked from 1991 to 1996 part time as R&D director at MECOS Traxler AG and as lecturer and deputy head at the Institute of Robotics, ETH Zurich. In 1996 he was appointed as professor for autonomous microsystems and robots at the Ecole Polytechnique Fédérale de Lausanne (EPFL) where he served among others as member of the direction of the School of Engineering (2002-06) and funding chairman of the Space Center EPFL.
      Roland Siegwart is a board member of the European Network of Robotics (EURON), and servedas Vice President for Technical Activities (2004/05) and is currently Distinguished Lecturer (2006/07) of the IEEE Robotics and Automation Society. Recently he has been appointed as Member of the Swiss Academy of Engineering Sciences and the -Bewilligungsausschuss Exzellenzinitiative- of the Deutsche Forschungsgemeinschaft (DFG).Roland Siegwart’s research interests are in the design and control of systems operating in complex and highly dynamical environments. His major goal is to find new ways to deal with uncertainties and enable the design of highly interactive and adaptive systems. Prominent application examples are personal and service robots, autonomous micro-aircrafts, walking and swimming robots and driver assistant systems.

 

National Colloquium on Sustainable Aviation @ University of Toronto Institute for Aerospace Studies
Jun 21 @ 9:00 am – Jun 22 @ 5:00 pm

The National Colloquium on Sustainable Aviation features experts from across Canada converging at the UTIAS Centre for Research in Sustainable Aviation (CRSA) to discuss the future of environmentally friendly aircraft.

Since developing environmentally sustainable airplanes requires a very wide spectrum of expertise, a broad array of academics and industrial practitioners is invited to speak on their subjects of specialisation. It is important to note that many experts work on fields related to sustainable aviation, though it may not be their primary focus. For example, many engineers work in the area of composite materials. While they may not view themselves as working on sustainable aviation, their expertise is necessary for making airplanes lighter: this is essential for improving the environmental performance of aircraft.

The diversity of expertise relevant to sustainable aviation exhibited at the colloquium complements the in-depth and themed focus of the annual Summer School on Sustainable Aviation, which will be held June 14 – 15, 2017. On even numbered years, the National Colloquium has an international equivalent, the International Workshop on Aviation and Climate Change.
