Robert Adam, one of the organizers of the Green Speed Cup in Germany and pilot of the Flight Design CTLS that ended the competition in seventh place, shared some information on the challenges faced by pilots in this year’s event. “We had 12-15 knots crosswind today (only a little less yesterday) and Tim-Peter (-Voss) managed this demanding taildragger (the SPACEK s.r.o. SD-1 microlight) calmly!” This very light and short-coupled airplane flies with a variety of two- and four-stroke engines, but Voss’ had a Verner JVC-360 four-stroke unit of 38 horsepower. It averaged a little over four liters per hour fuel consumption per 100 kilometers (59 mpg) over the practice day and two contest days. In the Green Flight Challenge, it would have been penalized for being a single-seater and thus having a lower passenger-mile-per-gallon figure than the two, and even four-seat entrants. The TDI turbo-diesel DA-40, for instance, would have had a 4X passenger mile per gallon figure if that had …
The Sixth Annual Electric Aircraft Symposium
The CAFE Foundation will hold its sixth Electric Aircraft Symposium on April 27 and 28, 2012 at the Flamingo Resort in Santa Rosa, California and at the Charles M. Schulz Sonoma County Airport, site of the Green Flight Challenge. Not only will there be a stellar lineup of speakers, but flying demonstrations of electric and hybrid aircraft, a first at any EAS. Jack Langelaan, team leader for the GFC-winning Electro Taurus G4 team, and Tine Tomazic from Pipistrel will share insights on the design and flight of the 403.5 epmpg aircraft. David Calley, Chief Technical Officer for Motor Excellence, will describe ideal low-RPM motors for electric aircraft, and Mark Moore from NASA’s Langley Research Center will share breakthroughs in distributed propulsion. And that’s all before the first coffee break! Typical of the packed schedules for all EAS’s, the rest of the presentations will fill your brain and lighten your spirit. Gene Sheehan will discuss his Quickie-like Feuling Green Flight Challenger …
Lucky 13 to Fly in Green Flight Challenge
Following rigorous evaluations of all aircraft to ensure they meet all standards for the contest, Dr. Brien Seeley, President of the CAFE Foundation, announced the 13 entrants who will compete in the Green Flight Challenge at Santa Rosa, California between July 11 and 17, 2011. This exciting event will offer the public a first view of some incredible designs and resourceful competitors. Since the minimum performance required for consideration includes things such as the ability to fly a 200 mile course at 100 mph or better average speed, the ability to clear a 50-foot barrier on a 2,000 foot runway during both takeoff and landing, and the efficiency to attain at least 200 passenger miles per gallon during the overall flight, all aircraft are obviously the most efficient aerial creations yet seen. Rules were established to encourage designers to make “real world”, practical craft rather than specialized designs that could win the contest but find no real purpose or willing owners. Even things such as cockpit design and …
Green Flight Challenge: It Might Look Like a Quickie…
But it will be the Feuling Green Flight Challenger, an entirely new iteration of the Quickie “formula” if Gene Sheehan, Vic Turner, Luke Leatherman and Allon McBee have their way. Created in the wake of the Vari-Eze’s and Long-Eze’s of the early 1970’s, the original Quickie was an 18-horsepower Onan industrial engine-powered irreducible flying machine with great speed for its low power and unbelievable fuel economy. The team’s GFC Challenger is electric, and a far cry from its cast iron past – or the iron-horse Harley-Davidson motorcycles that are part of its surroundings. “Feuling” comes from the high-performance motorcycle and automobile developer who started the company bearing his name. Jim Feuling had over 100 patents to his name, worked with the big names in the racing world, and created a 500 mile-per-gallon engine (at 55 miles per hour) for Honda’s streamliner and fielded a record-breaking motorcycle streamliner that clocked 333.847 mph on the Bonneville Salt Flats on October 20th, 1999. …
