Electrifly-In Bern 2022 is a new location after five years at Grenchen, Switzerland.  The Electrifly-In moved about 25 miles down the road to Bern’s bigger airport.  Started by the designers of the SmartFlyer, an innovative hybrid touring craft, the event was originally called the SmartFlyer Challenge. Organizers have the serious intent of saving aviation from the “shame” that has come to accompany flight itself.  “Aviation is pilloried by the public. Flying is seen as the main problem of the climate catastrophe and everyone who books a flight should have a guilty conscience and is labeled as a climate sinner. The social and political pressure to phase out combustion technology is steadily increasing worldwide. So the question is no longer if, …

Smartflyer Moves, Along with Former Namesake Fly-in

Smartflyer is a four-passenger, proof-of-concept light aircraft that can fly on pure electric power, as a hybrid with an av-gas powered generator, or as a hydrogen-fuel-cell-driven airplane.  It’s been under development for several years, but is moving production to Stelzach – just nearby.  Likewise, the Smartflyer Challenge, an electric aircraft fly-in, is moving from Smartflyer’s Grenchen, Switzerland home to Bern, a much larger field about 20 miles south. The Smartflyer SFX1 Electric-Flight.eu reports, “The fuselage of the Smartflyer SFX1 is slowly taking shape.”  Company founder Rolf Stuber OK’d production of the first carbon fiber reinforced plastic (CFRP) fuselage at Aerolite near Lucerne.  In a rented hall of 500 square meters (5,382 square feet), the “ready-to-install” drivetrain, consisting of a well-tested …

SmartFlyer is Looking Smart

Only a design concept just a few years ago, the SmartFlyer hybrid aircraft is swiftly approaching full-fledged reality.  CEO Rolf Stuber started the project and has been joined by Daniel Wenger, who shares design honors with him; and eleven others with a dazzling array of skills and degrees.  Every member of the team has built, flies or has flown in everything from gliders to “heavy” airliners. The team’s goal is to craft a “proof of concept” airplane which will fly by 2021. Facebook Updates Recent Facebook photographs show a nose section with a Rotax 914 engine driving a special generator, yards of orange cable connecting the big pieces, and a set of formers for what will probably be the fuselage …

e-Genius Gets Around Quickly, Inspires Others

Birds of the Same Tail Feather Configuration Prof. Dipl.-Ing. Rudolf Voit-Nitschmann (emeritus) had a lot to do with designing the 1996 Icare II solar-powered sailplane and the 2011 e-Genius.  Icare II set several world records in its 20 years, most under the guidance of pilot Klaus Ohlmann.  e-Genius won the award for being the quietest airplane at the Green Flight Challenge held in Santa Rosa, California, and was a close second to Pipistrel’s G4 in passenger miles per gallon (equivalent) energy use. Dipl.-Ing. Voit-Nitschmann was kind enough to explain to your editor how the propeller center came to be at the top of the tail on e-Genius.  It’s a similar configuration to that on the Icare II*, and one he …

SmartFlyer Challenge: Electric Airplanes Fill Swiss Skies

There are few times one will see more than one electric airplane at the same place – outside of perhaps, Friedrichshafen’s e-Flight Expo every year.  But to see them flying at the same field on the same day is an even grander delight.  That happened September 9 and 10 at Grenchen, Switzerland.  Grenchen hosted the world’s first all-electric fly-in – the SmartFlyer Challenge.  It drew an appreciable number of electric aircraft of all sizes and types despite the clouds and rain that kept some from scaling the mountains. An Electric Three-Plane Formation Flight The Siemens-powered Magnus e-Fusion from the Czech Republic, the electric Phoenix motorglider, and Stuttgart University’s e-Genius all flew formation with a Piper L-4, a World War Two …
