China Permits Two-Seat Electric Aircraft

Jane Zhanf of Silk Wings Aviation (see note), an aircraft consulting firm, commented on an earlier post about the RX1E, an airplane designed by Shenyang University students and demonstrated at two airshows over the last two years.  Similar to the Yuneec (GreenWings) E430, it is a totally different design. “CAAC (Civil Aviation Administration of China) just awarded[a]TDA (Type Design Approval) to them! “By the way, Yuneec E430 is not widely known in China, not an excuse for the wrong claim of being #1 from China though.  (Editor’s Note: The E430 is being developed by GreenWings, now based in California.  It uses a Yuneec motor.) “Given FAA and EASA don’t support electric SLSA (Special Light Sport Aircraft – allowed to be used …

AEAC Pulls in First 20 Deposits

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Aero Electric Aircraft Corporation (AEAC) and Spartan College of Aeronautics and Technology made joint announcements about their signing a “Training Program Development and Deposit Agreement” for the school to reserve the first 20 delivery positions for “Sun Flyer” solar-electric training aircraft being developed by AEAC.  This first such agreement by a major training program and an aircraft maker is a milestone for this new technology. The press announcement quotes Peter Harris, CEO of Spartan College, saying, “This agreement signifies our commitment to innovation and to serving the next generation of pilots. Spartan College is honored to be the first training school to formalize our collaboration on a complete training system that will make flight training more modern, accessible and economical …

AVweb Readers Weigh In on Electric Aircraft, Green Flight Challenge

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 0 Comments

Mary Grady of AVweb started an expanding dialogue with her recent opinion piece on NASA and the CAFE Foundation’s Green Flight Challenge sponsored by Google.   The stimulating and varied points of view reflect what is probably floating around in the general public’s perception of “green aviation,” ranging from total ignorance of what has been done already, to confusion about what it all means, to well-honed, technically aware arguments on both sides of the issue. Her thought that electrification is, “the first step down a long and bumpy road that could take general aviation in new directions,” was reinforced with the following reflections that might be similar to those that readers of this blog often experience. “For people who fly for …

In my dreams I fly like a bird… Martin Wezel 1964 – 2011

Dean Sigler Sustainable Aviation 1 Comment

It takes intelligence, courage and a special spark to design, build, and test fly an airplane.  It becomes a deep loss for all in the aviation community when that spark is extinguished.  We are saddened to learn of the death of Martin Wezel in the crash of a Yuneec E1000 he was scheduled to fly in the Green Flight Challenge.  Wezel was designer and distributor of aircraft such as the Viva, a high-performance motorglider that had brought him to the attention of Tian Yu, Chairman of Yuneec International. Yu reflected on the loss of Martin in a company announcement. In Germany, his wife Petra lamented the loss of her “dear man and best friend,” and vowed to continue operating the company to which he …

Getting Wired on the e-Spyder

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Stephan Boutenko of Alternair passed this along, and it is worth a read.  Jason Paur of Wired Magazine’s Autopia web site reports on flying Tom Peghiny’s e-Spyder, a combination of Tom’s Flightstar ultralight with a Yuneec motor, controller and battery. Paur’s impressions are highly positive, with the desire to continue the experience.  He notes, “Flying on battery power is about the unique experience of flying without the noise, vibration and smells of a traditional engine pulling you along. It’s an entirely different sensation. And like gliding, it is about the challenge of flying within the limitations of the aircraft and maximizing your time aloft. “’It’s like hypermiling a flight,’ Peghiny says.”  Hypermiling in automobiles is the act of conserving fuel …

LEAP Awards at WSEA

At the World Symposium on Electric Aircraft, AirVenture’s overview of electric aircraft progress, the morning session ended with the presentation of the LEAP (Lindbergh Electric Aircraft Prize) awards.  Erik Lindbergh, grandson of Charles and Anne Morrow Lindbergh and founder of the Creative Solutions Alliance, announced the winners at the July 30 session. According to the Alliance’s press release, “LEAP is a suite of prizes that recognizes significant contributions to the development of practical electric flight, and stimulates meaningful advances in the fledgling electric aircraft industry. LEAP awarded a total of $25,000 in prize money, an amount equal to the Orteig prize that was won by Charles Lindbergh for his 1927 solo crossing of the Atlantic Ocean. In doing so, Charles Lindbergh …

Yuneec Adds to Airplane, Motor Lineup

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Shanghai-based Yuneec, already promoting a line of electric paramotors, an electric trike, the two-seat E430, unveiled at last year’s AirVenture, and a series of motor/controller/battery combinations, has added to their offerings at AirVenture 2010.  New craft include two aircraft, the Apis 2 and Viva from Martin Wezel Flugzeugtechnik, a German designer and purveyor of sailplanes and light sport aircraft.   The Apis 2 is a derivation of the Silent electric sailplane, and in this application will be powered by a Yuneec motor system.  The Viva, a two-seat motorglider, was designed originally for an HKS-700E two-cylinder engine of about 60 horsepower, and will be converted, like the Apis, to Yuneec power. Spanning 15 meters (49.2 feet), the Apis 2 has a best lift-to-drag …

A Great Year and Gala Day for Yuneec

Dean Sigler Uncategorized 0 Comments

 Last year, we knew Yuneec for its tidy power package for paramotors, the 10 kW EPac.  We were awaiting developments on the EP200, a twin-motored, single-place ultralight that looked as though it would be powered by two EPac units.  Springtime, 2009 brought the news that a two-seater was under development, and summer brought surprise after surprise.  The 40 kW (54 horsepower) E430 made its first flights on June 12, 2009, followed by further testing on June 20.  Test pilot Sun Xun managed two flights of 15 minutes, achieving a top speed of 150 kilometers per hour (93 mph) a climb rate of 7 meters per second (1,377 feet per minute), and a maximum altitude of 300 meters (960 feet).  Sun …

Flying Magazine, in its November issue, has its usual stunning photo review of this year’s AirVenture at Oshkosh, Wisconsin, but adds a three-page review of the electric aircraft that showed up at the fly-in.  Robert Goyer, senior editor, is enthusiastic about the planes he saw, and gives the largest number of column inches to Yuneec’s E-430 two-seater.  Goyer has reservations about the aircraft’s performance and limited range, and turns to another Yuneec-powered craft, Tom Pehigny’s FlightStar e-Spyder, propelled by a 27 hp, single-battery pack system, with the assessment that this type of craft seems more suited to electric power in its current state of development.  Although Pehigny admits restrictions in terms of range so far, he “does point out some …
