Monday, October 3 was the second day of Nobel Prize announcements, but also marked the Green Flight Challenge Expo, sponsored by Google and staged under the control tower on Moffett Field, home of NASA Ames Research Center, Mountain View, California. The four airplanes that flew in the Challenge at Charles M. Schulz Sonoma Country Airport in Santa Rosa, California were joined by Greg Stevenson’s full-size mockup of his GFC design and a Pipistrel Virus that had won an earlier NASA/CAFE Personal Air Vehicle (PAV) Challenge. Stevenson’s airplane was a reminder that there were numerous entrants that, for a variety of reasons, could not attend. There is a huge number of aircraft in the wings, so to speak, that will fill these pages in the next months and years. 20 exhibitors showed off their visions of a greener future, and three rows of tents protected exhibitors and their displays from the rain that started mid-afternoon. At about 11:00 a.m., attendees were bussed to Building …
Green Flight Challenge – Day One
Sunday, September 25 marked the kickoff of the Green Flight Challenge sponsored by Google, a NASA Centennial Challenge managed by the CAFE Foundation, with a thorough technical inspection for each entrant, followed by a weigh-in. Held at the Charles M. Schulz Sonoma County Airport, the event is an event of international importance, despite the small turnout. With only four entrants making an appearance out of the original 13 that had announced and made it through the rigorous design review, there might be cause for disappointment. Consider, though, the Berblinger competition held in April at the Aero Expo in Friedrichshafen, Germany. 36 teams signed up, 24 made it to the Expo, 13 started the course and eight finished. The GFC has a comparable start-finish ratio, with many of the same issues stalling non-starters here as in Germany: lack of funds and schedule, regulation and fabrication difficulties. Despite the dropouts, Pipistrel, Stuttgart University, Phoenix Aircraft, and Embry Riddle Aeronautical University (ERAU) managed to field teams. In a …
Pipistrel Preparing for Green Flight Challenge
Michael Coates, American distributor for Pipistrel, shares some pictures and videos of the G4, four-seat, twin-fuselage electric motorglider a “technology demonstrator” for the company and its entry in the Google/NASA/CAFE Foundation Green Flight Challenge, which starts Sunday, September 25 in Santa Rosa, California. The Pipistrel team, headed by Jack Langelann of Pennsylvania State University, is working out Hollister, California’s airport, about 70 miles south of San Francisco and 150 miles from Santa Rosa. The team expects to fly to Charles M. Schulz field on “Friday or Saturday of the this week” for the competition. Pilot Robin Reid guided the big bi-fuselage craft through its paces and brought back this in-flight video, which shows the visibility is better than one would expect – except of the other fuselage, the nose of which can be seen just under the central propeller. Coates reports, “Hollister airport has been our base for the last four weeks as we continue to extend the flight envelope …
