Stuttgart to Barcelona Dipl-Ing* Ingmar Geiß, Deputy Project Manager for e-Genius with the Institute of aeronautical engineering at Stuttgart University shared the news that e-Genius flew with its range extender for the first time on September 15.  He notes that while the battery-powered airplane can manage trips up to 300 kilometers (186 miles), the hybrid engine/generator pod will enable flights up to 1,000 kilometers (620 miles).  This would equal a trip from Stuttgart to Barcelona, Spain, according to the e-Genius web site. As the school explains, “With [the] e-Genius hybrid most flights of a typical user case can be done in the cost and energy efficient battery mode – for all longer flights the range extender can be used. Generator …

Dr. Birgit Weißenbach, press and marketing director for the firm, announces that PC-Aero and Calin Gologan will appear at the ILA (Internationale Luft- und Raumfahrtausstellung, or International Aerospace Exhibition) Berlin Air Show being held between September 11 and 16 at Roger Airfield, about 11 miles southeast of the city. They will be showing, for the first time, their operational Electric Flight System, comprising their electric and solar-powered Elektra One Solar aircraft and a mobile solar charging station, the trailer in which the motorglider can be transported. Dr. Weißenbach notes that “At the Aero in Friedrichshafen/Germany this year we presented only a mock-up of the Elektra One Solar (Editor’s Note: as they did at AirVenture 2011, showing only stuck on, but …

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 …

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 …

A Useful Spreadsheet and GFC Handicapping Tool

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 1 Comment

For analyzing the greatest economy from an aircraft’s design, Howard Handelman, a highly-engaged reader of this blog, provides a link to his web site, which includes a downloadable spreadsheet he has devised that will give the inquiring reader hours of enjoyment. Handelman, self-described as, “just a retired IT guy,” with “weak math skills,” but a “compulsively curious” nature, has devised a tool for analyzing any airplane’s performance based on a few known variables, and which he has applied to many of the Green Flight Challenge’s aircraft. The basis for his analyses is his “triangle tool,” a wedge that can be used to help design propellers, “test [the] truth” of claimed aircraft performance, and estimate brake horsepower in real life circumstances (at …
