Sun Flyer’s Two and Four Seat Electric Aircraft

Dean Sigler Announcements, Electric Powerplants, Sustainable Aviation 0 Comments

George Bye has spent the last decade developing a viable two-seat training aircraft that would be electrically powered.  His efforts included a Cessna 172 that took wing on battery power, and have evolved to the current product, a sleek two-seater that has 105 deposits to buy worldwide. At AirVenture 2017, George displayed the Sun Flyer 2 and announced plans to introduce a four-seater, the Sun Flyer 4.  With ground tests complete on the aircraft and its 45-pound Emrax motor, George envisions flight tests coming this fall for the 2.  Even given successful flight tests, certification may take two to three years.  George has been working with the FAA to enable certification under Part 23 rules, and has made great headway …

 George Bye – Electric Aerospace in Small, Medium and Large

Dean Sigler Electric Aircraft Components, Hybrid Aircraft, Solar Power, Sustainable Aviation 0 Comments

George Bye has been crafting and testing electric aircraft for the last decade and now has four craft of varying size demonstrating the reach of his vision.  Bill Moore interviewed George for EVWorld.com recently.  We’ll review the airplanes with which George is involved, starting small and working up to a spectacular cross-country cruiser. Silent Falcon Although the UAV company associated with the Silent Falcon is not part of Bye Aerospace, it had its origins there.  Now located in Albuquerque, New Mexico, Silent Falcon operations are overseen by John Brown, former Chief Financial Officer (CFO) for Bye Energy. Silent Falcon’s glider-like 14-foot wing, high efficiency airfoil, electric power and high-efficiency solar cells allow up to five-hour surveillance flights.  Its ability to …

Sun Flyer Rollout

Yesterday, George Bye’s Aero Electric Aircraft Company (AEAC) rolled out its Sun Flyer, an electric two-seat training aircraft with photo-voltaic cells on the wing and tail to extend its range, and over two or three days, recharge its batteries.  With orders for 65 Sun Flyers already on the books, interest is high in this airplane. In an email, George informed your editor that, “We’re using the Enstroj Emrax 268 high voltage electric motor, rated at 100 kW and 400 volts nominal.  Of course, the motor ‘throttle’ is electronic.” He responded to a query about battery monitoring and protection: “Battery safety is multi-fold.  We monitor cells individually, cells within each ‘battery box’, (with electronic disconnect), battery box system electronic and mechanical …

Germany to Two Places in Austria – On Solar Wings

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

e-Genius spent July 4 crossing the Alps both ways from Germany to Italy, a first for a two-seat, battery-powered airplane.  Although the Elektra One Solar from PC-Aero GmbH is lighter and seats only one, its flights starting two weeks before and ending two days before e-Genius’s journey are equally proud accomplishments. The outgoing flight started in Unterwössen, Germany on June 25, crossed over the Grossglockner and landed, according to PC-Aero’s description, “In the sunny town of Lienz in East Tyrol, Austria.  The flight took around 2.5 hours. After the successful flight on the south side of the Alps, Elektra One Solar started [on its next trip] on 2 July (few days before the eGenius of the University of Stuttgart also flew …

WattsUp Becomes Alpha Electro – Training Market Warms Up

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

With today’s AVWeb report from Mary Grady at Aero in Friedrichshafen, Germany, the wraps are off the commercial reality that Pipistrel is ready to market its Alpha Electro, a new airplane for the training market.   The production version of the former WattsUp, the airplane’s primary mission is to provide training in the pattern for aspiring pilots. Details abound in the video, with Tine Tomazic, Chief Engineer for the Slovenian firm, showing Mary the features of the craft.  One of the best features may be its 100,000 euro price tag, well under pricing for many conventionally-powered light sport aircraft that would compete in the trainer market. Since Aero brings in exhibitors from all over the world and incorporates an E-Flight Expo, …

Powering Imagination in Seattle

Seattle’s Museum of Flight on Boeing Field will host a one-day event, Powering Imagination, an electric flight symposium organized by Erik Lindbergh, grandson of Charles and Anne Morrow Lindbergh. Presentations will be held in the William M. Allen Theater at the Museum, starting at 10:00 a.m. on Saturday, February 28 and ending at 5:00 p.m.   Admission is free, but RSVP to cwilcox@museumofflight.org to guarantee a seat. Topics include an update on the NASA LEAPTech aircraft being designed and built by Joby Aviation and powered by Joby motors.  This 20-motor (!) aircraft will achieve a high coefficient of lift from the motors that distribute thrust over the entire span. Eric Lindbergh will talk about the Quiet Flight Initiative, a multi-pronged approach to …

AEAC Pulls in First 20 Deposits

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 …

Two “New” Battery Contenders

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

With Tesla’s announcement that its new battery pack for its Rev. 3 Roadster will increase the car’s range to as much as 400 miles (your mileage may vary), two contenders are putting proclaiming equivalent or better performance from their unique technologies.  These companies are relatively new, but have fairly long development histories.  They are both moving toward commercializing what otherwise would be academic demonstrations of their technologies. EnerG2 – Taking Carbon to New Levels A Seattle, Washington-based materials development firm, EnerG2’s Carbon Technology Platform (CTP), is based upon a polymer chemistry foundation, and according to the company, “represents an ability to engineer and synthesize high-performance, uniquely tailored high-purity carbons, at large scale and low cost.”  The company makes CTP materials …

Calin Cologan and George Bye staged a joint press event on the Sunday evening before AirVenture started.  Held in the Redbird Tent on Wittman Field, it drew hundreds who saw the Redbird flight simulators and a Diesel-powered Cessna, but were stopped short by the yellow and blue Sun Flyer, a single-seat proof-of-concept version of what will soon be a two-seat battery/solar training aircraft. Forming a new firm based on the strengths of PC-Aero in Germany, and Bye Aerospace and Redbird Flight Simulators in America, they promise an electric training aircraft for the near future.  Unlike the tandem two-seaters PC-Aero is developing in Germany, American Electric Aircraft Corporation will produce a side-by-side craft, often preferred for communication between instructor and student. In this Da …
