In September last year, Attie and Uys Jonker presented the SAIMechE John Orr Lecture at the University of the Wi****ersrand. They spoke about the dream of building the best glider in the world, the development of the JS1 and then the development of the JS3 and getting it to Australia in time for the World Champs a year ago. The lecture was recorded and is still available to view at the following link: http://tinyurl.com/johnorr2017

It's well worth watching. The first hour or so is Uys talking about the JS1 and the second hour is Professor Attie talking about the design of the JS3, and the leaps they have made in utilising computational fluid dynamics in the design. The attention to detail in the development is incredible and goes a long way in understanding why the JS3 is performing the way it is. The audience was predominantly Mechanical Engineers who sat enthralled for the entire 2 hours.
