Denver, Colorado – July 18, 2016 – In a December 2015 noise measurement evaluation, the Sun Flyer technology demonstrator was found to be nearly silent in flight test. A high-definition video overview of the noise tests conducted by the National Park Service featuring the technology demonstrator for the “Sun Flyer” has been released and is available at https://nps.gov/subjects/sound/video.htm (click on “A Quiet Flight”).
Aero Electric Aircraft Corp. (AEAC), the developer of the Sun Flyer solar electric flight trainer, participated in noise research for the National Park Service at Centennial Airport in early December 2015 to help determine the amount of noise generated by electric-powered aircraft.
AEAC flew its single-seat electric technology demonstrator aircraft while a scientist and representatives from the National Park Service gathered sound data. Other participants in the test effort included Erik Lindbergh with Powering Imagination and a representative from Colorado State University (CSU) to do an audio and video recording of the event.
Conventional aircraft overflight provided comparison for the AEAC electric test aircraft. According to Kurt Fristrup, Branch Chief, Science and Engineering for the National Park Service, the electric aircraft produced roughly 30 dB less, or 1/1000th the noise, of conventional aircraft.
“We continue to advocate that electric-powered flight brings numerous cost and environmental benefits, but noise reduction is certainly near the top of the list of benefits,” said George Bye, CEO of AEAC. “Our thanks to all those who participated in the noise measurement evaluations, particularly the National Park Service and Colorado State University.”
The Sun Flyer aircraft is intended to be the first FAA-certified, U.S.-sponsored, practical, all-electric airplane serving the flight training and general aviation markets. The 2-seat proof of concept prototype for the Sun Flyer solar-electric flight trainer was unveiled to the public in May and is completing final integration, and will begin power-on tests at its home station at Centennial Airport near Denver. The prototype will be on display next week at Booth 66 during EAA AirVenture 2016.
