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 …

Flexibly Keeping Batteries from Blowing their Cool

Meltdown – not a term one wants to hear when confronting an obstinate boss or while levitating in his or her new Tom Swift Electric Octo-copter.  But it is a real specter confronting electric vehicle users, and one amplified to positive levels of terror in flight. Two groups of researchers have come up with novel ways of quelling that terror and getting rid of the normally flammable electrolyte that helps make lithium battery fires truly memorable. If researchers at Chapel Hill and Washington State University are successful in their research, that acid electrolyte can be replaced with something safer and as a bonus in both cases, batteries using these new substances will perform better and longer. Researchers at the University …

Chip Yates Chasing New Records

This morning’s email brought the following missive from Chip Yates, known for his high-speed attacks on Pikes Peak, the Bonneville Salt Flats and the skies above China Lake, California. “More good news for our electric airplane programs in the lead-up to our planned attempts to set 4 FAI official world records shortly, and then break our own top speed record of 202.6 mph for electric planes in front of the 150,000 crowd at the California Capital Airshow in Sacramento October 5-6!” Chip’s normal enthusiasm may have shortened the battery life on this Long-ESA (Electric Speed and Distance) record-setting aircraft, since his pushing the pack’s limit in all three motorcycle and aircraft record attempts probably pushed the envelope a bit too …

Getting Wired on the e-Spyder

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 …
