MGM COMPRO, a Czechoslovakian motor and electronics supplier, announced that they had participated in finally making the Phoenix motorglider an electric machine. Jim Lee and co-pilot Jeff Shingleton had originally intended to fly the airplane at the Green Flight Challenge three years ago, but contented themselves with competing in the Rotax-powered machine and “only” winning third place in the event. Their competing did elicit a great deal of interest in the machine, though. MGM says, “We are very glad that we can present you a very successful project, [the] U-15 Phoenix of the Czech entrepreneur Martin Stepanek. MGM COMPRO plays a decisive role in a development of industrial controllers for this fully electric aircraft. As described in the blog three years ago, the electric PhoEnix is a “nice airplane,” and one that would take many willing pilots on many cross-country jaunts. Martin originally planned to use a Czech industrial motor for power, but ended up developing his own powerplant that …
Green Flight Challenge – Days Three and Five
As if in answer to the most fervent prayers by CAFE Foundation organizers, Tuesday, September 27 dawned as a bright, windless morning, perfect for the planned 200 -mile aerial trek that each of four teams would undertake in the Green Flight Challenge sponsored by Google. Each would fly a large, tightly-followed out-and-return loop around the Sonoma Valley, reaching the radio tower array on the peaks north of Geyserville, then returning for one of three passes (the fourth being the descent to land) over the CAFE Foundation hangar at the west end of the Charles M. Schulz Sonoma County Airport. Each would have to reach at least 4,000 feet at the end of a 17-mile climb and would need to track within one mile on either side of the Challenge course’s centerline. Pilots would need to stay on the outside edge of turnpoints, but shave their margin to within one-half mile on each pylon-type turn. To help monitor that precise flying, Steve …
Green Flight Challenge – Day Two
Monday morning, September 26, many of us had our first view of an electric airplane in flight. After the weighing team rolled Jim Lee and Jeff Shingleton’s Phoenix motorglider from the hangar onto its impound location and completed initial weigh-ins for the remaining three aircraft, the airplanes were staged for the first flying event of the Green Flight Challenge sponsored by Google. With technical inspections and weighing completed, the four airplanes lined up to check their noise levels and their ability to clear an imaginary 50-foot barrier atop a cherry picker 2,000 feet from the top of the number “9” on runway 19 at Santa Rosa, California’s Charles M. Schulz Sonoma County Airport. As each aircraft rolled out to their takeoff point, the cluster of photographers under the cherry picker focused and waited for a green flag to fall at the takeoff point. All the aircraft passed cleared the 50-foot flag, and e-Genius was judged to be quietest of the entrants …
PhoEnix GFC Update
Jim Lee’s informative and beautifully illustrated blog features “PhoEnix with the capital E in the middle,” the motorglider he will fly in the CAFE Green Flight Challenge in July. Electrically powered with a Krall 44 motor, it has a pointy nose and retractable gear to make it more slippery than the already high-performance Phoenix without the capital E and with a mere Rotax behind the propeller. According to Lee, the 14.5 meter (47.57 feet) modified Schempp-Hirth Discus wing is raised above the low position of the gas-powered version to make room for the electrically-retracted gear, which hides in what was originally a luggage compartment – another change from the standard Phoenix. The wing is configured to win the GFC, as is the rest of the airplane. Lee, the U. S. distributor for Phoenix Air, says in his blog, that “the PhoEnix is purpose built for a race. A race that offers big bucks for the winner, but with a bar set so …
Phoenix or PhoEnix – a Nice Airplane
While at Sun n’ Fun in Lakeland, Florida, we couldn’t help but notice Jim Lee’s Phoenix Air Phoenix, an S-LSA (Special Light Sport Aircraft) motorglider from the Czech Republic, posed as it was on the line of march into the air show area proper. Your editor was interested in the PhoEnix, the electric version of the proper looking and highly attractive Rotax-powered version in the Light Sport Aircraft display display, next to its Pipistrel neighbors. There were a great many middle European LSAs being shown, but the Phoenix had ended up on the Airshow’s promotional poster, neatly avoiding the FA-18s of the Blue Angels. The electric version will be competing in the Green Flight Challenge, so revelations from Jim Lee, the airplane’s U. S. distributor and pilot in the GFC, were the usual furtive responses to detailed questions. All competitors are being careful to avoid revealing too much until after Larry Ford’s presentation at the fifth annual Electric Aircraft Symposium in …
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 …
