George Bye, CEO of Bye Energy and head of the Green Flight Project, hopes to test fly the electric Cessna 172 in the spring of 2011.  Recent illustrations show the “full-dress” electric craft with Ascent solar cells, a high-tech propeller, streamlined cowling, and vortex collectors at the wing tips’ trailing edges.  Each element is intended to extend the range and efficiency of the airplane, a strong selling point, particularly in electrically-powered machines. Ascent Solar’s thin-film cells are thinner than a human hair, and thus will not impede the airflow over the wing’s surface. As the cells’ efficiency grows with development, they will provide greater flexibility of operation.  Their resistance to failure, demonstrated in the video, will enhance the reliability of …

In a press release datelined Oshkosh, Wisconsin, July 26, Cessna Aircraft Company announced, “That it is collaborating with Bye Energy, Inc., an integrator of clean, alternative energy technologies for business and general aviation aircraft, to design and develop an electric propulsion system for a Cessna 172 proof of concept (POC) aircraft.”  Bye Energy is a Colorado-based aerospace company, and its CEO, George Bye, presented the Green Flight Project, his vision of the electric 172 at this year’s Electric Aircraft Symposium in Rohnert Park, California on April 24.  The fact that Cessna would agree to such collaboration is a significant step, and a verification of the market research Bye and his group have done.  Possibly fueled by the fuel question – where …

CAFE Makes the Top of Kitplanes’ Cover

 While at the local magazine store, or the proverbial fine book store, you’ll be able to spot Kitplanes’ August 2010 issue easily.  The yellow letters on the cover line above the magazine title pop with upper-case intensity: “FUTURE SHOCK: CAFE’S Electric Aircraft Symposium.” Not only does the fourth annual Electric Aircraft Symposium get pride of place on the magazine’s cover and in four pages inside, but Marc Cook, editor-in-chief for the publication, titles his “Around the Patch” editorial “Making Electric Aircraft Exciting,” and proceeds to share his surprised discovery of respect for the new Toyota Prius, and to praise the husband-wife team of Bill Dube’ and Eva Hakansson, battery builder and racer, respectively, of Killacycle, the 0-60 in one second electric …

The Future is Electric, and Attracting Attention

FlightGlobal.com, the online version of Flight International Magazine, has an overview of the electric aircraft scene in its April 6, 2010 release.   Among the many producers and proponents of electric flight noted in the article, Dr. Brien Seeley of the CAFE Foundation is quoted extensively, as is Calin Gologan of PC-Aero in Germany, both to present at the fourth annual Electric Aircraft Symposium, at Rohnert Park, California on April 23 and 24.  The article ponders the hopes of two hybrid electric aircraft powerplant developers, George Bye, featured in a February 21 entry in this blog, and Flight Design’s Oliver Reinhardt, the firm’s technical director.  Both face the issue of retrofitting existing light planes with their new engines, and the challenge …

Bye Energy’s Green Flight Project

Dean Sigler Electric Powerplants, Sustainable Aviation 5 Comments

In his presentation at AirVenture 2009, George Bye, CEO of Bye Energy, set forth some ambitious goals for his company. This included the development of a hybrid electric power system for light aircraft (under 250 horsepower) with target markets for general aviation and experimental homebuilt aircraft. Bye explained that light, powerful electric motors and Lithium-ion batteries have achieved a mature technology level that makes this an ideal time to enter this new market. On February 18, Bye introduced the proof of concept systems that will enable him to achieve this.   The Green Flight Project consists, in its first phase, of an electric motor based on the UQM 125, a 90-pound, 95-percent efficient unit that puts out up to 168 horsepower (output …
