Feathers in Flight Inspire Anti-Turbulence Technology

“Inspired by nature’s own anti-turbulence devices – feathers,” researchers at RMIT University in Melbourne, Australia, have developed a system that emulates the movements of feathers with which birds control their flight path in the most turbulent conditions. Dr. Case van Dam gave a talk at the 2014 Electric Aircraft Symposium on controlling aircraft in turbulence and providing smoother rides with Gurney flaps, jet flaps and micro tabs.  The RMIT team chose to mimic the motions of feathers on a bird’s wing to gain many of the same advantages.  The Unmanned Systems Research Team learned enough to file a provisional patent on the system, detecting disturbances in the air ahead of the airplane.  Both approaches might help the electric commuter aircraft …

Who would pass up a chance to stay at a nice resort, attend lectures that challenge and inspire, and meet at poolside with speakers who bring some of the sharpest minds in the world to bear on some of the biggest problems we all face?  Let’s face it.  Global warming probably won’t be going away anytime soon, and aviation seems destined to play a bigger part in polluting our otherwise near-perfect atmosphere. Unless…we learn how to make our favorite activity (in the top five for most of us, anyway), into a more responsible way to travel and recreate.  Since solving the problems which go with that responsibility will involve the best in aerodynamics, power systems and new, efficient technology, the …
