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 …

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 …

Green Flight Challenge: It Might Look Like a Quickie…

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 9 Comments

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 …
