On August 23, 2011, the Embry Riddle Aeronautical University’s Green Flight Challenge hybrid-powered modified Stemme S10, the Eco-Eagle, began its ground tests on the Daytona Beach International taxiways, “Getting ATC used to us!” The next day saw several ground-skimming “flights,” starting at 2-feet, and rising to 10 and 50-feet high runs, all with the gear down. The day’s flights ended with a trip around the pattern for the airport’s longest runway. August 25 saw a morning excursion of 45 minutes, with the airplane flying in the face of the approaching Hurricane Irene. Test pilot Mikhael Ponso reported beautiful clouds and no high winds during the seven laps around the field. As he tested the gear retraction and various flap settings, he was able to sort things out for the upcoming GFC flights in Santa Rosa, California during the last week in September. The school’s Eco-Eagle has a Rotax hybrid-power system originally developed for Flight Design, a German firm that builds …
The Future is Electric, and Attracting Attention
FlightGlobal.com, the online version of Flight International Magazine, has an overview of the electric aircraft scene in its April 6, 2010 release. Among the many producers and proponents of electric flight noted in the article, Dr. Brien Seeley of the CAFE Foundation is quoted extensively, as is Calin Gologan of PC-Aero in Germany, both to present at the fourth annual Electric Aircraft Symposium, at Rohnert Park, California on April 23 and 24. The article ponders the hopes of two hybrid electric aircraft powerplant developers, George Bye, featured in a February 21 entry in this blog, and Flight Design’s Oliver Reinhardt, the firm’s technical director. Both face the issue of retrofitting existing light planes with their new engines, and the challenge of obtaining supplemental type certification for such modifications. Highlighted is the 2011 Green Flight Challenge, in which an airplane achieving 200 seat miles per gallon at 100 mph (or an alternative energy equivalent mileage) can earn the CAFE Foundation’s $1.5 …
