Aerodynamic Efficiency in Small and Large Aircraft
The aerodynamic efficiency of an aircraft is conventionally measured by the dimensionless lift to drag ratio, L/D, and higher values are almost always better. The design or evolution of flying devices involves a lot more than this single measure, but it is still interesting to enquire how close any given device might be to some reachable optimal solution, or even just a better one. Two sets of such enquiries will be outlined, one involving scales where birds, bats and micro-air vehicles intersect in design space, and one where we will claim that most commercial transports are operating far from likely superior solutions. Tracks for future research on these points also overlap in interesting ways.
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
