John McGinnis, designer and promoter of the Synergy aircraft, had a brief twinge of regret when Kickstarter, the crowd source funding site, turned down his project for inclusion in their site. Luckily, the gloom was dispelled when friends and supporters prompted Kickstarter to change their mind. A great deal of this was brought about by the eloquent efforts of Patrick Panzera of Contact Magazine, Howard Handelman, a friend and supporter of John’s, and Brian D. Wendt, Aeropunk.com blogger. John’s press release, issued today, spells out the importance of Kickstarter’s decision. “Kalispell, MT, May 16, 2012: “Since its unveiling last year, John McGinnis’ award-winning1 Synergy aircraft project has garnered a lot of critical attention for its advanced aerodynamics, but its sexy looks and prototype flyby videos certainly don’t hurt the pitch: major fuel savings and a modern passenger experience. “Looking something like a futuristic cross between a sailplane and a fighter jet, the boldly different five-seat aircraft promises a quieter, more comfortable …
AVweb Talks to Dr. Seeley About EAS VI
The sixth annual Electric Electric Aircraft Symposium, CAFE’s premier event, got a lot of press attention this year, including lead story status from AOPA and acknowledgement from Engadget and AVweb. We’ll start with the one that’s most fun to listen to – a podcast from AVweb. Mary Grady of AVweb interviewed Dr. Brien Seeley, President of the CAFE Foundation, about the just completed Electric Aircraft Symposium at Santa Rosa, California, which drew participants from at least eight countries and 10 multi-national corporations. With Federal Aviation Administration representation and a former Environmental Protection Agency head signed up to attend, the Symposium drew some high-level attention this year. Dr. Seeley was enthusiastic about the rapidly maturing technology and industry, with Tom Gunnarson from the FAA and Ronald Gremban of ForSites Corporation working toward standards and practices for electric aircraft. When asked about the thought that FAA rules for small electric aircraft might be five to 10 years out, Dr. Seeley noted the …
Vimeo Viewing of First Ever Electric Aircraft Charging Station
Dr. Brien Seeley, President of the CAFE Foundation, points us toward a video his son Damon just posted to Vimeo. It depicts part of the 2011 Green Flight Challenge sponsored by Google, for which the Foundation played host. Dr. Seeley explains, “NASA’s Chief Technologist Joe Parrish refers to the Wright Brothers in the video as Sonoma County Supervisor Mike McGuire and I cut the hose to a gasoline dispenser nozzle.” The symbolic hose is then proudly replaced by a very real electric charging station for airplanes, capable of providing a continuous 9,600 Watts to each of 12 aircraft and used to charge the Pipistrel G-4, e-Genius and Embry-Riddle’s hybrid Stemme during the contest. The video features great in-flight footage of the two pure-electric competitors from the GFC, and makes one wish for the day when private flight is quiet, pollution-free, and inexpensive. The G-4, according to Pipistrel CEO Ivo Boscarol, made the two 200-mile flights in the contest on about …
Want a Ride in Synergy?
Howard Handelman, a regular reader and observant critic of the CAFE Blog, and Patrick Panzera of Contact magazine fame, are soliciting support for an effort to help John McGinnis finish his Synergy aircraft, unfortunately unable to make its Green Flight Challenge date, but nearing the finish line, none the less. Kickstarter.com recently rejected John’s attempt to raise funds for the nearly complete aircraft, a radically new and somewhat controversial approach to obtaining high performance on relatively low power. John has shared his insights into the aerodynamics of the project and invited a lively discussion (now closed) on the Experimental Aircraft Association’s forums pages. Synergy under construction – an imposing sight The Internet has made possible fund-raising “crowd sourcing” in which interested people all over the world can contribute to enterprises they feel worthy of support. As Handelman explains, “Keep in mind that Gates, Jobs and Rutan started in the equivalent of their garages. Then remember the pre-internet crowd funding of …
Fastest Electric Vehicle Design at EAS VI
Dr. Brien Seeley, President of the CAFE Foundation, has made the following announcement: “The Chief designer of the F-22 Raptor has prepared another spectacular design: The World’s Fastest Electric Vehicle. This new aircraft design will be presented along with the other outstanding talks at next week’s CAFE Electric Aircraft Symposium, April 27, 28 in Santa Rosa, California (Sonoma Wine Country). This symposium, dedicated to the burgeoning new domain of emission-free flight, now has representatives from Boeing, Bosch, IBM, Honda, Nortrhop-Grumman, Japan Air Lines, Rolls-Royce, Siemens, Aerovironment, FAA, Cummins, Cessna, Lycoming and many other companies enrolled to participate.” The high-speed electric may be a response to Ivo Boscarol’s pledge to put up $100,000 of his Pipistrel G-4 winnings at last year’s Green Flight Challenge for the first supersonic electric aircraft. Program Details can be found here. There is still time to pre-register online here.
Pantera Rollout at Friedrichshafen
Friedrichshafen is the place to be for new aircraft announcements, with PC-Aero yesterday and Pipistrel today showing off new aircraft. Pipistrel, having won the Green Flight Challenge in September, could not rest on its laurels, today sharing the news that, “The revolutionary 4-seat all composite design, featuring retractable undercarriage, 200 kts cruising speed, 1000 NM range, comfortable cabin and a choice of three powerplants – conventional/hybrid/electric – is presented to the World for the very first time.” Those lucky enough to be at Aero 2012 , hall A5, will doubtless flock to see the Pantera, a graceful design that does 200 knots (230 miles per hour) on its 200-hp, Lycoming IO-390 engine while burning 10 US gallons per hour. This relative fuel economy (a recent Mooney ride saw the airplane consuming 16 gallons per hour at a lower speed) allows Pantera to carry four people 1,000 nautical miles (1,150 statute miles). CEO Ivo Boscarol is obviously proud of his new …
Deturbulating a Record Flight
Sumon K. Sinha, Ph.D., P.E., and head of Sinhatech, had a part in the recent Federation Aeronautique Internationale (FAI) record by Mr. Jean-Luc Soullier and recorded in a blog entry on March 10. Dr. Sinha wrote that, “CAFE Foundation’s Blog on March 10th, 2012 did not mention that the Colomban MC-30 aircraft had Sinhatech’s Deturbulator tape treatment on the wing upper surface as shown in the attached photograph. I would like to have this added to complete the description of the aircraft.” Sinhatech Deturbulator tape is an innocuous-looking strip applied along the span of a wing at a point which will trigger a response from the tape, which oscillates in the airflow, increasing lift and mitigating skin friction, according to company white papers. Dr. Sinha points out that, “This is the first independently recorded flight with wing Deturbulator treatment by FAI. It is also the first independently recorded flight with full-span Deturbulators on a powered aircraft.” The Sinhatech web site …
Pipistrel’s Flight Through Wine Country
Brien Seeley forwards a video of Pipistrel’s historic, Collier Trophy nominated electric powered flight. He notes, “It applies its performance data file and a weather map overlay to annotate scenes of the visual beauty of the Sonoma Wine Country,” a feature that will also delight visitors to Charles M. Schulz Sonoma County Airport when they attend the electric aircraft flight demonstrations that are part of this year’s Electric Aircraft Symposium. The Team will present details of their aircraft and its achievement at the 6th Annual CAFE Electric Aircraft Symposium on April 27, 2012 in Santa Rosa, for which registration can be obtained online. The video will remind one of the weather overlays Dr. Jack Langelaan created for his autonomous soaring exercises, and which were also shown to be helpful in general aviation flight planning and execution.
Dr. Jack Langelaan and Heuristic Navigation Techniques
“Heuristic: involving or serving as an aid to learning, discovery, or problem-solving by experimental and especially trial-and-error methods ; also: of or relating to exploratory problem-solving techniques that utilize self-educating techniques (as the evaluation of feedback) to improve performance ” m-w.com (Merriam-Webster online) Dr. Jack Langelaan’s talk at the fifth annual Electric Aircraft Symposium was one of at least two to use the term, “heuristic,” and sent this writer scrambling for the dictionary. His presence in Santa Rosa, four months ahead of his return with the Green Flight Challenge winning Pipistrel G4, showed at least one of the facets to the planning that would make the G4 victorious. Careful flight planning, as any flying instructor will gladly inform you, is a prerequisite to getting the greatest efficiency out of an airplane. Historically, much flight planning involved following mapped-out air routes and flying at prescribed altitudes, at least in controlled airspace. Recent efforts to release those constraints have come about through …
Better Batteries: Enviable Achievement from Envia
Envia, a startup battery company in Newark, California, has announced a much-anticipated breakthrough in lithium-polymer storage cell energy density. Although tested to 300 charge/discharge cycles, the new battery should show at least 1,000 successful cycles before we get too excited. Excitement will build, though, as the announced 400 Watt-hours per kilogram doubles the current energy density standard for lithium batteries. This would reduce a Leaf’s battery pack from about 600 pounds to 300 pounds, or keeping the same weight, double the car’s range to about 250 miles. Dr. Brien Seeley points out that the Green Flight Challenge-winning Pipistrel G4 could have traversed 400 miles with a reserve on such batteries. According to Envia, quoting from the official report, “’The Naval Surface Warfare Center, Crane Division (NSWC Crane) Test & Evaluation Branch was tasked by Advanced Research Products Agency – Energy (ARPA-E) to perform Verification & Validation testing on two high capacity lithium ion pouch type cells, manufactured by Envia Systems …
