Sunflyer Takes to the Air

Dean Sigler Announcements, Batteries, Electric Powerplants, Sustainable Aviation 0 Comments

Following assorted powerplant and taxi texts, the prototype Sun Flyer 2 prototype took to the air over Centennial Airport (KAPA) south of Denver, Colorado.  Further tests will expand speed, altitude, and endurance capabilities, according to Bye Aerospace. George Bye, Founder and CEO of Bye Aerospace, enthused, “We are excited about the future and the potential the Sun Flyer family of aircraft has to revolutionize general aviation, providing improved affordability and accessibility.  Lower operating costs are key to solving the student pilot drop-out rate, which is curtailing the successful attainment of badly needed airline pilots. The Sun Flyer 2’s $3 hourly operating costs are 10 times lower than traditional piston-engine flight trainers, with no carbon emissions and significantly reduced noise.” Such …

The Coming Golden Age of Electric Air Races?

Dean Sigler Batteries, Electric Powerplants, Hybrid Aircraft, Hydrogen Fuel, Sustainable Aviation 1 Comment

An Electric Great Air Race 100 years ago, a great air race – “The Great Air Race” – in fact, was held with competitors flying from Great Britain to the Northern Territories of Australia.  Crews had 30 days to make the trip, and considering the reliability of engines at that time and the primitive nature of aerial navigation, very little time to relax. Of the six teams that entered, only two made it, three crashing (two fatally) and a fourth team being imprisoned in Yugoslavia as suspected Bolsheviks.  Only two teams finished, and only one received the 10,000 Pound Sterling prize (about 544,577 pounds today – over $775,000), enough to cause the six crews to accept the high risk  involved. …

Pipistrel Alpha Electros Come to California

News from Joseph Oldham, founder of the Sustainable Aviation Project, and Michael Coates, United States master distributor for Pipistrel Aircraft, heralds the largest delivery of electric training aircraft to date.  Four Pipistrel Alpha Electro Trainers showed up at Fresno, California’s Chandler Airport, all part of the Sustainable Aviation Project.  Described as “a public-private collaboration to reduce the cost of flight training through the use of all-electric general aviation airplanes,” the Project might become a role model for future electric flight training. On March 19, two 18-wheel trucks delivered two 40-foot shipping containers.  Each container carried two Alpha Electros, two chargers, and a pair of replacement battery packs for each airplane.  It took a mere two hours for a volunteer crew …

Swiss Movements – aEro 1 and aEro 2

Electric Flying Inspires Bigger Plans Dufour Aerospace, based in Visp, Switzerland, and within sight of the Matterhorn, has been flying aEro 1, a Silence Twister-based electric aerobatic craft, for the last two years.  Read the pilot report on the surprising performance and the quiet flight experience in the aEro 1 to get some idea of how future flight will be a welcome relief from the noisy today’s noisy passage.  “Electric motors are so incredibly efficient. They have a huge torque and you will take off much faster than with regular engines. Our aEro 1 takes off after 70 meters of runway – at 2/3 of the available power. “The first real takeoff and flight afterwards was really mindblowing. I set …

From Anime to Low-Powered Electric Flight

Dean Sigler Electric Powerplants, Solar Power, Sustainable Aviation 0 Comments

A team in Japan has flown a low-power electric canard motorglider, and is now building a more conventional, lightweight electric aircraft.  Members of Aircraft Olympos Ltd. on the large island of Hokaido have been instrumental in building and flying everything from a jet inspired by one of Hayoa Miyazaki’s anime productions (Nausicaa (Dove) Of The Valley Of The Wind – 1984) to some fascinating electric aircraft. Brian Carpenter met Tota Ueno, a worker on the project, and visitor at one of Brian’s maintenance classes in Corning, California.  Brian was selected by the National General Aviation Awards Committee as the recipient of the 2017 National Aviation Maintenance Technician (AMT) of the Year Award.  His classes in ultralight aircraft maintenance and two-stroke …

Forget the Airborne Pizza!  Chip Yates Sends 700 Pounds!

Dean Sigler Electric Powerplants, Hybrid Aircraft, Sustainable Aviation 0 Comments

Recent news shows aerial drone delivery of small packages from an Amazon Warehouse or pizza from the nearest Dominos, but such packages are lightweight trifles compared to the 700 pounds Chip Yates promises to drop from the sky. Such loads are necessary in conflict and disaster areas, where material heavy enough to hold off an enemy or feed hordes of refugees is essential.  Fifty-kilogram sacks of rice or electric generators are necessary for survival, and a heavy-duty delivery system will almost always come in handy. Chip, head of Yates Electrospace, has gone over 200 mph on an electric motorcycle, taken the UQM motor from that machine, and powered his Long-ESA aircraft to also top 200 mph.  As Aviation Week and …

Electric Triplanes, Personal Sky Taxis, and Urban Mobility beyond Belief

Dean Sigler Announcements, Sustainable Aviation 1 Comment

The Third Annual Sustainable Aviation Symposium again promises to be the premier gateway to innovation, mind-expanding discussions, and a glimpse into the future that this gathering will help make possible. Reserve your spot today to be on the leading edge of that future. VTOLs, ESTOLs and the Future of Sky Transit, May 11 and 12 in the beautiful Grand Ballroom of the Pullman Hotel San Francisco Bay in Redwood City, will go beyond the technical to the truly world-changing. We’re going to explore some big issues: “How can we make electric aviation broadly accessible and of meaningful scale, in terms of climate change, renewable energy, urban communities, and global markets?” “How can aviation make human life better? Join us to …

Zee?  Kitty Hawk? Cora?

Dean Sigler Announcements, Sky Taxis, Sustainable Aviation 0 Comments

Different Names, Different Configurations Zee, One of two aircraft companies funded by Google founder and CEO Larry Page, has been a highly mysterious business.  Its web pages mostly gave discrete job descriptions for those willing to sign up for a mostly undefined mission.  Occasional glimpses of patent drawings, spy shots of a multi-rotor craft in Google’s Mountain View, California parking lot came into view, and later, in-flight shots of other, different looking craft came from Hollister, California. Kitty Hawk, the other company funded by Larry Page, seems to have subsumed Zee and produced a 12-rotor, single-propeller aerial taxi about the size of a Cessna 150, but capable of vertical takeoffs and landings and seamless transitions to forward flight.  A white …

Get a Spine!  Flexible, High-Density Energy Storage

The Vertebrate Battery “Prof. Yuan Yang of the engineering school at Columbia University (New York) modeled, designed, built, and fully evaluated a configuration that emulates the spine of vertebrates, while providing 85% of the energy density of a prismatic Li-ion cell with equivalent volume.” According to Power Electronics.com. Professor Yang’s 14-member team, working in the impressively-named Center for Precision Assembly of Superstratic and Superatomic Solids, and  inspired by the flexibility of the human spine and its ability to repeatedly endure bending and twisting, designed a battery that emulates the characteristics of what is in essence a structural battery.  We know from experience that our backbones can perform some pretty extraordinary twists and turns – witness the supple routines of gymnasts …

Starling Jet Comes in Three Sizes

 The Starling Jet now joins electric or hybrid flying commuter craft from sources all over the world. A Middle-East backed, London-based project, the Starling Jet is swoopy and high-winged, and comes in three sizes with different missions. The Commuter Craft Trifecta Time, a most precious commodity, is the major selling point for most of these sky taxis.  Saving an executive’s schedule enhances productivity, whether it’s whisking a CEO over the traffic jams in Dallas or Dubai.  For many similar machines, the impetus is to democratize the flight experience, offering many an Uber-like experience at Uber-like prices.  Samad Aerospace, creator the Starlings, is looking toward a more exclusive market. All such craft promise the convenience of point-to-point transportation, foregoing intermediate shuttle …
