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 designing and crafting airplanes quiet enough to be flown over national parks, areas now off-limits to noisy overflights. This is one facet of Powering Imagination, the other two Electric Flight and Alternative Fuels. Erik promises video updates from Europe and an …
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 than ever before.” The same announcement has George Bye, CEO of AEAC, thanking Spartan College for their collaboration and support. “Our goal with Sun Flyer is to achieve lower operating costs and enhanced safety features for a training airplane by …
Two “New” Battery Contenders
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 used in lead-acid batteries, ultracapacitors, lithium batteries and natural gas storage. They’ve recently signed a partnership agreement with BASF, showing their acceptance by a multinational powerhouse. Their specialization in “hard carbons” and combining those with silicon for battery electrodes, leads …
AEAC Debuts Sun Flyer at AirVenture 2014
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 Vinci Institute presentation, George Bye discusses the keys to performance for his aircraft, which include clean aerodynamics, high efficiency, a light carbon structure, and solar energy. Nest will come a “big performance step – endurance” – and possible perpetual flight …
EAS VIII: Calin Gologan and George Bye Make a Sunlit Announcement
Calin Gologan of PC-Aero GMBH in Germany and George Bye of Bye Aerospace in Colorado made an auspicious announcement about practical solar-electric propulsion advances for manned and unmanned aircraft. Their presentation at the eighth annual Electric Aircraft Symposium pointed toward a possible rebirth in flight training at prices not seen in decades. Their two companies are forging an alliance called the Aero Electric Aircraft Corporation (AEAC), which will produce a two-seat, side-by-side sport and training aircraft called the Sun Flyer. As stated in their press release, “The Company will bring to market the first U.S.-sponsored, practical all-electric airplane serving the training, recreational and general aviation markets.” Gologan and Bye’s talk at the Symposium focused on their joint plans to create practical solar-electric propulsion advances in manned and unmanned small aircraft. Each partner has demonstrated experience in forging new directions for electric light aircraft. Calin Gologan’s PC-Aero, for instance, consults on propulsion, structures and aerodynamics, and has produced Elektra One, a …
Silent Falcon in Production
Bye Aerospace has announced initial production its small unmanned aircraft system, the Silent Falcon™. Produced by Silent Falcon UAS Technologies (SFUAS), a former subsidiary of Bye Aerospace, Inc., the Silent Falcon is a mere 25 pounds, but is able to perform six- to 12-hour missions on a mix of battery and solar power. The airplane, of all composite construction, will serve both military and civilian markets, with its small size and quiet operation able to serve well in either capacity. Its size and weight are virtues in a competitive market, giving “unprecedented performance and value… ready for the market place,” and already in “low rate initial production,” according to John Brown, President of SFUAS. He adds that “sales teams are targeting domestic, Latin and South Asia region trade shows in the next few weeks.” Small enough with carrying case to fit in a Pelican case (the same type in which professional camera operators carry their gear), the airplane can be …
EAS VIII – A Day and a Half You’ll Never Forget
Who would pass up a chance to stay at a nice resort, attend lectures that challenge and inspire, and meet at poolside with speakers who bring some of the sharpest minds in the world to bear on some of the biggest problems we all face? Let’s face it. Global warming probably won’t be going away anytime soon, and aviation seems destined to play a bigger part in polluting our otherwise near-perfect atmosphere. Unless…we learn how to make our favorite activity (in the top five for most of us, anyway), into a more responsible way to travel and recreate. Since solving the problems which go with that responsibility will involve the best in aerodynamics, power systems and new, efficient technology, the CAFE Foundation has invited experts in these fields with demonstrated successes in meeting such challenges. To be held April 25 and 26, 2014 at the Flamingo Resort in Santa Rosa, California, the event will host speakers on everything from practical, …
Bye Aerospace Provides Stratospheric Persistence
George Bye, founder and head of Bye Aerospace, introduced the Silent Falcon unmanned aerial vehicle earlier this year at the Association for Unmanned Vehicle Systems International (AUVSI) meeting. He has two other relatively low-cost but highly capable offerings which could stretch the limits of unmanned aerial system (UAS) capabilities. The first, the Starlight program, involves lifting a variable geometry, solar-powered airplane to great heights with a balloon, hovering with it for up to four months, and releasing it when needed to allow refurbishing, refitting and relaunching. This two-stage system provides the same kind of surveillance offered by a satellite, but at a much lower cost. The balloon is a static device, used only to provide the altitude necessary, and the aircraft needs to provide power sufficient to allow station keeping and run its sensor systems for the period it is at altitude. When launched, the nose and tail-mounted electric motors power the airplane on its way. It can slide its …
Silent Falcon – A Solar-Powered UAV
While Boeing and AeroVironment proceed with stratospheric, hydrogen-powered giants such as the Phantom Eye and the Global Observer for extremely long-range surveillance and monitoring duties, an Albuquerque, New Mexico company is exploring the potential of a small, lower-altitude, hand-launched craft that can search – and if necessary – destroy. A recent report from Volta Volare’s Paul Peterson attending the Association for Unmanned Vehicle Systems International conclave in Las Vegas, Nevada and an email from George Bye, Chairman and CEO of Bye Aerospace, alerted your editor to the new reconnaissance aircraft. George wrote, “While the electric Cessna program continues to advance under the leadership of Charlie Johnson and a new name, ‘Beyond Aviation’, we have continued our research into solar-electric hybrid propulsion in unmanned aircraft. At the early August 2012 AUVSI conference, my company, Bye Aerospace together with Silent Falcon UAS Technologies, unveiled a small solar-electric powered drone. The remarkable economics and technology is proven and the performance benefits have been demonstrated.” …
Not Your Father’s 172
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 the overall airplane. George Bye has noted an economy of operation that might relight some aviation enthusiasts’ desire to go flying. Standard 172s cost about $35 to $50 per hour in direct operating costs, with those costs climbing as oil …
