Stephen Boutenko, founder of Alternair, LLC and Karl Young, founder of Extreme Capacitors have found common cause in analyzing how best to make an electric Light Sport Aircraft (LSA) a possibility.   Alternair’s Amp LSA was featured in a blog entry last year, and Karl Young’s work with ultracapacitors was the subject of his presentation at this year’s Electric Aircraft Symposium. Alternair has recently established a temporary design department in Prescott, Arizona (in association with Embry Riddle Aeronautical University) and is moving his manufacturing facility to Ashland, Oregon, where he hopes to begin production of the highly-sophisticated Amp. Although Amp will be developed around existing lithium-polymer battery technology, Young reports that his creation of high power/high energy ultracapacitors has demonstrated, …

An LSA With the Electric Heart of an Airliner

Stephan Boutenko, Alternair President and founder, seeks a Light Sport Aircraft alternative, an airplane looking like an LSA, but loaded with features that will allow it to keep pace with the rapidly changing options coming to electric flight. Inspired by Yuneec’s E-430 but disappointed by its slow cruising speed, Boutenko was determined to create something more in line with LSA performance criteria. He also wanted to take advantage of the knowledge he had gained from years of experience with heavier aviation to create an integrated system that would allow flexibility and expandability in the development of his airplane. Unabashedly conventional in appearance, the low-wing, tricycle geared monoplane is conceived to make a pilot transitioning from an internal combustion powered machine …
