A frustration borne by homebuilt aircraft designers for years has been that of finding an appropriate, reasonably-priced powerplant for aircraft in the single and small two-seat range. Early experimenters often converted motorcycle engines to their ultralight needs. Continentals, Lycomings, and Franklins filled those needs in the 1930s and ‘40s, and other than Rotax and a few smaller manufacturer’s offerings, there really haven’t been any replacements since then. Electric powerplants, however, can be found in the motorcycles being produced by many American and foreign companies now, with more to come from Europe and Japan. Designers looking for available electric motors and “plug-and-play”* complete systems may want to look at the 2015 Zero Motorcycle lineup. Since one Zero motor has flown at the Arlington, Washington Fly-in and at AirVenture 2013, we can attest to the demonstrated performance. Zero’s newer model motors, controllers, and batteries can be found on the latest bikes from the company. Their specifications are certainly indicative of light weight …
Call for EAS VIII Papers
Dr. Brien Seeley, founder and president of the CAFE Foundation, shared this message today. “The CAFE Foundation is accepting presentation proposals for the 8th Annual Electric Aircraft Symposium, to be held April 25-26, 2014 in Santa Rosa, California. This international graduate level program will cover a comprehensive range of topics and will emphasize the latest breakthroughs in the rapidly growing domain of electric powered aircraft. Faculty and attendees will include experts from leading aerospace, electronics and energy companies. Topics will include aerodynamics, motors, energy storage, energy harvesting, control systems, recreational aircraft, propulsion, robotics, avionics, airspace integration, manufacturing, business cases and airport land uses. “Interested parties should email inquiries and abstracts to: cafe400@sonic.net“
Yuneec Returns to America as Greenwing
Under the direction of CEO Tian Yu, Yuneec International is back in the U. S. as Greenwing International, selling the single-seat e-Spyder and two-seat e430, as well as a range of motors, controllers, and battery packs. Based at Cable Airport near Los Angeles, California, the group has been assembling and testing the first of the Flightstar-based e-Spyders and will have several on hand at AirVenture 2013 in Oshkosh, Wisconsin next week. The group recently had an illustrious name as test pilot. Erik Lindbergh shares his thoughts about his first flight in an electric airplane. “After five years working to accelerate the development of the electric aircraft industry I have finally realized my dream to fly an electric aircraft, thanks to Tian Yu and his Yuneec e-Spyder.” Modestly claiming video editing and ultralight aircraft skills still in their infancy, Lindbergh explains, “Take off was supposed to be just a crow hop on the runway, but I didn’t feel comfortable putting it …
