Aspects of Aircraft Design and Control
by Olivier Cleynen
A series of eight projects on selected aspects of aeronautical engineering, with accompanying introductory lectures, taught in 2011-2013. They were designed for third-year engineering students. Pre-requisites are a good grasp of Newtonian mechanics, some understanding of aircraft flight, and a familiarity with the aviation sector. See this series of articles about the course for some background information.
