Brian Carpenter’s EMG-6 Webinar

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

Brian Carpenter, designer of the EMG-6 motorglider which he’s shown over the last several years at AirVenture, will stage a webinar to discuss “the design and development concepts of this new electric motorglider.”  His talk will have special “Emphasis on the integration of the electric propulsion concepts that he believes will change the face of the light aircraft and ultralight industry.” Your editor has visited Brian’s Corning, California workshop several times, and always found new and innovative approaches to producing a low-cost, self-launching motorglider, with several ways to simplify construction and to power the craft.  It will be interesting to see progress on the newest motor (apparently still under development) Brian has presented on his web site. He has been …

RX1E, Sun Flyer Both Score More than a Score (of Orders)

China Daily reports, “The world’s first electric passenger aircraft to gain an airworthiness certificate has been produced by China.”  Whether the “first” certification statement is true will probably become a matter of debate, with Pipistrel’s Alpha Electro being certified in France and seeking more general approvals from other countries including America.  Pipistrel has been selling a Taurus Electro G2 self-launching sailplane for the last several years, and makes the following claims for it. “Taurus Electro G2 is the only electric 2-seat aeroplane in serial production available on the market. Furthermore, Pipistrel believes it is the only truly useful electric aircraft out there, because the electric drive is applied to the glider airframe, where battery capacity is not a limiting factor in …

Dr. Seeley Speaks at AIAA Conference, NASA Dryden

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation, Uncategorized 0 Comments

Dr. Brien Seeley, Founder and President of the CAFE Foundation, has been giving a series of talks at the Experimental Aircraft Association’s AirVenture 2013, before a gathering of technical experts at NASA’s Dryden Flight Test Center, Edwards Air Force and at the American Institute of Aeronautics and Astronautics (AIAA) International Powered Lift Conference in Los Angeles. The International Powered Lift Conference focuses on the latest developments in Vertical or Short Takeoff and Landing (V/STOL) aircraft research, concepts, and programs, something of great interest to CAFE in its development of airplanes capable of using pocket airports. Pocket Airports will require a special type of airplane – electric, according to Dr. Seeley, and capable of taking off with a ground roll of …

Aviat Flies Dual-Fuel Airplane to Oshkosh

Dean Sigler Sustainable Aviation 0 Comments

Your editor spent much of his time at AirVenture 2013 in or around the Innovation Pavilion, the Experimental Aircraft Association’s nod to experimentation on a grand scale. Flanking the doors into the pavilion were two approaches to making flight more efficient, the LAM Ailerons on a Cessna Corvallis and a dual-fuel system on an Aviat A1-C Husky CNG; “CNG” standing for “compressed natural gas.” Stu Horn, President of Aviat Aircraft, is proud of the all-American nature of the airplane, most components other than avionics having their origin in this country.  Even the fuel for this proof-of-concept Husky is a domestic product, and a possible reflection of its back-country home.  Afton, Wyoming, where Aviat makes Huskies, has resurrected the Pitts Special, …

Pipistel, the innovative Slovenian company that won the Green Flight Challenge with its G4 electric four-seater, continues to earn plaudits from the aviation industry. At this year’s AirVenture, the Experimental Aircraft Association’s annual gathering at Oshkosh, Wisconsin, the company was honored with the Dr. August Raspet Memorial Award and original and pace-setting design work exemplified in Pipistrel products. The Exerimental Aircraft Association has awarded the “Dr. August Raspet Memorial Award” annually since 1960 “to a person who has made outstanding advancements in the field of light aircraft design and the Experimental Aircraft Association.”  John Thorp, Lockheed engineer and designer, was the first recipient, with those following including Curtiss Pitts, Burt Rutan, Alan and Dale Klapmeier and Gordon Pratt.

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 …

Green Flight Challenge, AirVenture Electric Contest Postponed

Dean Sigler Diesel Powerplants, Electric Powerplants, Sustainable Aviation 1 Comment

Both the CAFE Foundation’s Green Flight Challenge and the Experimental Aircraft Association’s AirVenture Electric Flight Prize are being postponed: CAFE’s for at least a few months and EAA’s until next year’s AirVenture. The CAFE Foundation’s announcement reads simply, “Circumstances have required that the Green Flight Challenge be postponed for at least 2 months. Its new dates will be posted here very soon.”  The GFC was to have been held between July 10 and July 17 at Santa Rosa, California’s Charles M. Schulz field. The EAA is holding off because of delays in ensuring that all entrants will be certified and properly registered for the competiton. Their news item reads, in part, “‘As with any new, emerging technology, time is an essential element to ensure …

Another Electric Lazair

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Besides the incentives offered by the Green Flight Challenge and the Lindbergh Electric Aircraft Prize, a venerable institution is encouraging electric flight with a series of prizes.  The Experimental Aircraft  Associations plans on awarding $60,000 to electric flight competitors during this year’s AirVenture in Oshkosh, Wisconsin. According to EAA’s Newsline, “One entry in the EAA’s $60,000 Electric Flight Prize during AirVenture comes from a well-established design, the Electric Lazair, based on an ultralight designed more than 30 years ago by Dale Kramer, EAA 145132. Between 1979 and 1985, his company, Ultraflight, produced about 1,200 kits. Calling the twin-engine Lazair ‘an ideal vehicle for electric conversion,’ Kramer wrote that he has dabbled in trying to ‘electrify’ one several times.” Kramer recounted making …

The Electric-Powered Aircraft, A Sequel

Dean Sigler Electric Powerplants 1 Comment

David Ullman, a professor at Oregon State University in Corvallis, Oregon, author,  and owner of his own consulting firm, Robust Decisions, has published part two of his article, “The Electric Powered Aircraft,” that first appeared in Kitplanes’ October 2009 issue (see our October 18, 2009 entry, “Hear the Hum?  Kitplanes Does”) .  You won’t have to rush to the nearest bookstore for the sequel, since this is online in the Experimental Aircraft Association’s Experimenter.  A great deal of the Experimenter is fired up with speculation and skepticism about electric aircraft and their feasibility in the current issue, including an editorial by Patrick Panzera, long-time engine guru and editor of the e-zine.  A great many of the readers’ comments have a “not ready for …
