David Ullman, a professor emeritus at Oregon State University, predicted electric flight’s future in articles in 2009* and 2010**.  His predictions have come (mostly) true and David is working to fulfill the rest.  His background in mechanical and aeronautical engineering provides credibility for his prognostications, and he’s taking practical steps to take electric aviation to a next, very creative level. While Uber’s Elevate Summit in Dallas earlier this year focused on big-money players in the vertical aviation world, David and co-creator Vincent H. Homer promoted their paper, “The IDEAL for Near-VTOL Aircraft.”  IDEAL represents “Integrated Distributed Electric – Augmented Lift” flight, using “thrust from distributed electric propulsion to improve the lift and drag performance of the aircraft during takeoff, cruise …

One of the biggest thrills this year at Oshkosh was getting to see Eagle Flight Research Center’s DA-36 run its YASA electric motor.  Eagle Flight, an outgrowth of Erik Lindbergh’s Powering Imagination program he’s been pursuing for the last several years, aims to create quiet electric aircraft that will carry sight-seers over National Parks and Monuments.  Such flights would not disturb people or wildlife below, and would give a Gabriel’s eye view of the most pristine places in our country. International Approval His ideas have met with international support.  As noted on the YouTube video of their meeting, “… Flavia Schlegel (Assistant Director-General (ADG) for the Natural Sciences) at UNESCO in Paris… gave an enthusiastic endorsement of our eSpirit of …
