Michael Coates, the U. S. General Distributor for Pipistrel Aircraft, sent the following missive from Ivo Boscarol, General Manager and Founder of the Slovenian company, now in its 26th year. “Dear All, “It is my pleasure to inform you that our friend Hugues Duval after reading the information that Pipistrel was blocked in flying across the English Channel today became the first electric aircraft to cross the English Channel in his CRI-CRI E-Cristaline Electric aircraft. “As Duval already had the permanent permit to fly his aircraft there was no need to ask for a permit to fly over the English Channel, but only to fill the flight plan. It was possible to keep the flight information secret up to the …

WATTsUP at Pipistrel

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

No, that’s a statement and not a question.  Taja Boscarol of Pipistrel sent the following announcement this morning.  WATTsUP, their new two-seat electric trainer took its maiden flight on August 8th.  As part of its 25th anniversary celebrations, Pipistrel will display the airplane at the Salon de Blois airshow, France, on 30-31 August 2014. This is the third announcement of an electric trainer by a major aircraft manufacturer, counting Airbus with its anticipated e-Fan developments and American Electric Aircraft Corporation (AEAC) with its Sun Flyer.  We could count four with Adventure Aircraft’s EMG-6 under development in California for the ultralight market.  This would mark a potentially historic turnaround for General Aviation, with promised operating costs significantly lower than for internal-combustion …

Eurosport Crossover Sports Many Tricks

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

We’re used to seeing motorgliders which pop an engine or motor up on a tall stalk behind the cockpit, then retract it into the slim tailboom for minimum drag.  Why not do the same with two electric motors on each side of the airplane, tucking them in a slender fuselage for soaring? Emails with Eurosport’s Tom Leite and perusal of the Portuguese firm’s web site and on-line brochure verified that almost everything on the Crossover motorglider is electric and retractable. Tom notes, for instance, “Our motor/props fold into the fuselage: [they are] 3-phase PMSM motors up to 40Kw at takeoff each.”  In the video, see the long, spar web-like structure with lightening holes that separates the two motors as they …

On March 28, Pipistrel rolled out its prototype Panthera, a sleek four-seat cruiser destined to be the first production hybrid aircraft and eventually, Pipistrel’s second four-seat electric airplane. It is currently powered by a Lycoming IO-390, 210 horsepower engine.  At Pipistrel’s factory in Ajdovscina, Slovenia a team of engineers and technicians fired up the engine for the first time and performed ground runs, “verifying design parameters and engine operation.” Pipistrel’s press release quotes Ivo Boscarol, their CEO: “It is very exciting to witness the tests and see the aeroplane come to life for the very first time. This is definitely a very important milestone in the development of Panthera. We look forward to the continuation of tests and the first …

Dr. Brien Seeley, President of the CAFE Foundation, has made the following announcement: “The Chief designer of the F-22 Raptor has prepared another spectacular design: The World’s Fastest Electric Vehicle. This new aircraft design will be presented along with the other outstanding talks at next week’s CAFE Electric Aircraft Symposium, April 27, 28 in Santa Rosa, California (Sonoma Wine Country). This symposium, dedicated to the burgeoning new domain of emission-free flight, now has representatives from Boeing, Bosch, IBM, Honda, Nortrhop-Grumman, Japan Air Lines, Rolls-Royce, Siemens, Aerovironment, FAA, Cummins, Cessna, Lycoming and many other companies enrolled to participate.” The high-speed electric may be a response to Ivo Boscarol’s pledge to put up $100,000 of his Pipistrel G-4 winnings at last year’s …

Pantera Rollout at Friedrichshafen

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation Leave a Comment

Friedrichshafen is the place to be for new aircraft announcements, with PC-Aero yesterday and Pipistrel today showing off new aircraft. Pipistrel, having won the Green Flight Challenge in September, could not rest on its laurels, today sharing the news that, “The revolutionary 4-seat all composite design, featuring retractable undercarriage, 200 kts cruising speed, 1000 NM range, comfortable cabin and a choice of three powerplants – conventional/hybrid/electric – is presented to the World for the very first time.” Those lucky enough to be at Aero 2012 , hall A5, will doubtless flock to see the Pantera, a graceful design that does 200 knots (230 miles per hour) on its 200-hp, Lycoming IO-390 engine while burning 10 US gallons per hour.  This …

Green Flight Challenge Winners

Monday, October 3 was the second day of Nobel Prize announcements, but also marked the Green Flight Challenge Expo, sponsored by Google and staged under the control tower on Moffett Field, home of NASA Ames Research Center, Mountain View, California. The four airplanes that flew in the Challenge at Charles M. Schulz Sonoma Country Airport in Santa Rosa, California were joined by Greg Stevenson’s full-size mockup of his GFC design and a Pipistrel Virus that had won an earlier NASA/CAFE Personal Air Vehicle (PAV) Challenge.  Stevenson’s airplane was a reminder that there were numerous entrants that, for a variety of reasons, could not attend.  There is a huge number of aircraft in the wings, so to speak, that will fill these …
