Erik Lindbergh, founder of LEAP, announced the first winner of the Lindbergh Prize for Quietest Aircraft at the NASA Green Flight Challenge. The prize was awarded to e-Genius, a two-seat electric airplane piloted by team leader Eric Raymond and Klaus Ohlmann. The plane was designed and built by University of Stuttgart Institute of Aircraft Design under the direction of Professor Rudolf Voit-Nitschmann and his assistants Len Schumann and Steffen Geinitz. Take off noise levels of the competitors ranged from a minimum of 56dBA to a maximum of 72dBA. e-Genius won with a takeoff range of 56 – 62dBA. By comparison, the takeoff noise of a turbo-fan aircraft at a similar distance is 110dBA, over 16 times louder.
