Dean Sigler Solar Power, Sustainable Aviation 0 Comments

We are excited to share this press release from Eric Raymond at Solar Flight.  Being in on things at the beginning of an extraordinary new technology is something that we strive for in this blog.  We were alerted to this by Dr. Abraham Van Helsing from the Transcendental Aerodynamics Department of the University of Transylvania.  He has been advising Eric on some arcane aspects of what most will agree are nearly unbelievable propulsion techniques. For immediate Release April 1, 2017 Today Solar Flight Inc. is proud to announce the roll out of its newest electric aircraft, the Monarch. In secret development for the last 2 years, it breaks new ground for this small aircraft development firm. The most revolutionary aspect …

Smartflyerchallenge – Europe’s First Fly-In for Electric Powered Aircraft

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Air meets have been an important part of aviation history, bringing pilots, planes nad the public together in a symbiotic gathering.  This was true in aviation’s genesis; things gaining a tremendous impetus with air meets throughout Europe and America following Wilbur Wright’s 1908 public demonstrations near Le Mans, France. René Maier, ex-Colonel of the Swiss Army and current President of the newly formed organization team for an annual event organized at the Grenchen Regional Airport, has announced the SmartFlyer Challenge, touted as the first fly-in for electric aircraft.  The event, to be held September 9 and 10, 2017, will make Grenchen “the center of electric flight,” according to the organizers.  Static and air displays of electric and hybrid-electric powered aircraft …

How Cheaply Can One Fly?

Dean Sigler Batteries, Electric Aircraft Components, Sustainable Aviation 1 Comment

How low(cost) can you go and still fly?   That question forms one of the pursuits of the Minimalist Airplane Study Group, hosted by William Rich on Yahoo Groups.  He may have found an answer that leads to several intriguing alternative uses for the type of electric powerplant described below.  Use of model aircraft components leads to a low-cost build, and judicious use of off-the-shelf parts from other hobbies keeps costs low and speeds up the development process. He points to a hack from Laserhacker.com, which uses a motor, controller, propeller batteries and connectors one might find at the local hobby shop.  This assemblage manages to fly a paramotor despite the small size of the motor and the relatively small size …

Eric Raymond: Skyping from the Sky

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

Eric Raymond and his wife Irena fly their Sunseeker Duo from the Aeroporto Voghera Rivanazzano near their home in Voghera, Italy.  The Provincia di Pavia provides wonderful architectural and scenic backdrops for their flights, something captured briefly in a video they filmed last year for Skype and Microsoft.  To Eric’s surprise, the commercial was finally released this month. The Raymonds and their collaborators are part of a larger advertising campaign for Skype and Microsoft, with their high-tech offerings complementing the wireless communications tools and the ad’s graphics. Eric and Irena, John Lynch, and Jason Rohr perform well for the cameras, but Eric had an extra challenge in the aerial filming.  “I was flying in formation with a Phantom drone!” Microsoft …

Solar Impulse Makes it to Mountain View

Dean Sigler Solar Power, Sustainable Aviation 0 Comments

At 11:44 PDT, April 22, Solar Impulse 2, expertly piloted by Bertrand Piccard through tricky winds above Moffett Airfield, made its second landing in the United State, almost three  years after Solar Impulse 1 had left on its flight eastward* and just in time to close out Earth Day. HB-SIA (Solar Impulse 1) made its trip across America in six hops, none lasting more than 21 hours and 22 minutes.  HB-SIB (Solar Impulse 2) flew six hops between Abu Dhabi and Nanjing, China emulating the stages of the American crossing in distance and duration.  Things reached record-setting levels after that.  The 44-hour trip from Nanjing to Nagoya, Japan gave pilot Andre’ Borschberg a real workout, followed by his record-setting 117-hour …

EnergyOr Ups the Ante for Endurance

Dean Sigler Fuel Cells, Hybrid Aircraft, Hydrogen Fuel, Sustainable Aviation, Uncategorized 0 Comments

Staying airborne for more than an hour or two might seem like a huge leap for battery-powered electric aircraft.  Inspired designers like Eric Raymond have been able to use solar cells to extend their flights to near-perpetual states.  A large craft like Solar Impulse 2 remains in flight for up to five successive days and nights only through careful energy management and flight planning.  Researchers are looking at hydrogen fuel cells as an alternative to batteries, with the hopes of achieving greater endurance. One company, EnergyOr, has developed two still small fuel cells to power their rotary- and fixed-wing drones, setting several records in the process.  With payloads and maximum takeoff weights that enable carrying a 4K camera or large …

Second Sunseeker Duo Calendar Here

Dean Sigler Solar Power, Sustainable Aviation 0 Comments

Eric Raymond, designer and builder of three solar-powered aircraft, along with his wife Irena, take some pretty astonishing pictures.  They work from a unique aerial platform, the Sunseeker Duo they completed and now fly together.  Their travels and adventures are large-screen worthy, and they share them with their 2016 Calendar.  Eric explains. Dear Solar Flight and glider fans, We had the most amazing year ever flying the SUNSEEKER DUO here in Europe and we would love to share the vistas with you! Just now we are finishing our photo calendar in time for Christmas, and offering it for anyone’s gift to a pilot or themselves. Since our flight in the SUNSEEKER DUO to the Swiss Alps was very successful and …

Sunseeker Duo, Dynamic Duo Do the Alps

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Irena Raymond shared the following about her and huband Eric’s flight across the Alps from northern Italy to Switzerland and return – a four-day tour of the mountainous country, and validation of the Sunseeker Duo’s performance. The latest of a series of accomplishments, the trip’s mission was to “stop and show the airplane at different airports,” according to Irena. Remember that Eric crossed the United States on solar power in Sunseeker I in 1990, 23 years before Solar Impulse managed the feat. Eric crossed the Alps on his way from Friedrichshafen, Germany to the World Air Games in 2009, guiding Sunseeker II over sometimes cloud-shadowed peaks. Now he and Irena have made a two-person Alps crossing and tour of the …
