Taja Boscarol of Pipistrel in Slovenia relays the information that NASA has tested Pipistrel’s electric propulsion system as part of its electric flight research for the X-57 program.  It would seem reasonable to start by checking out Pipistrel’s well-tested motor package, one of the few that comes with fully-matched controller, batteries, and ancillary gear. NASA performed its tests on its 13.5-foot Airvolt stand at the Armstrong Flight Research Center at Edwards Air Force Base, California.  Heavily instrumented, the Airvolt stand collects data through “high-fidelity sensors,” and transmits the collected information to a data acquisition unit that processes, records, and filters the measurements.  NASA and Pipistrel should be able to make good use of this data. Normally installed on the Taurus …

Pipistrel’s Four-seat, Side-by-side Electric Airplane

One of the most anticipated presentations at this year’s Electric Aircraft Symposium in Santa Rosa, California, April 29th and 30th, was that of the CAFE Foundation’s Vice-President, Larry Ford.  He had the enviable task of unveiling the contenders in the Green Flight Challenge – a mix of conventional aircraft powered by unconventional means, unconventional craft being sent aloft by a variety of the mundane and the exotic, and wildly unconventional concatenations of technologies. Pipistrel’s G4 turned out to be simple math: G2 plus G2 equals G4.  The configuration could hardly be preconceived, though.  According to Pipistrel USA’s Michael Coates, “This unique design has come about by grafting two Pipistrel Taurus aircraft together with a center section which is some 5 meters (16 …

A Trio of Winners at Friedrichshafen

Erik Lindbergh, as part of his Lindbergh Foundation, has instituted a suite of prizes to recognize and , “Accelerate development of practical electric flight, and stimulate meaningful advances in the emerging electric aircraft industry.”    Having presented four prizes at last year’s Experimental Aircraft Association AirVenture, Lindbergh followed up at Aero-Friedrichshafen 2011 as part of the Berblinger Competition – which drew 24 entrants and eight aircraft that actually completed the Friedrichshafen-Ulm-Friedrichshafen out-and-return course.  With sponsors including Sergei Sikorsky, son of Igor Sikorsky, a competitor for the original Orteig Prize that prompted Charles Lindbergh’s 1927 New York to Paris flight; His Serene Highness Prince Albert II of Monaco, who backs LEAP; and Messe-Friedrichshafen, hosts to the Aero 2011 and to the First …

A Second Slovenian Self-Launching Sailplane – With a Solar-Powered Trailer

Tine Tomazic of Pipistrel alerted the blog that his firm started series production of their Taurus Electro G2, a first for a two-seat electric aircraft, according to Pipistrel, claiming 20 customers who will receive their G2’s by year’s end. Improvements over the prototype led to the “rev.2” series version of the self-launching sailplane, which also is the first electrically-powered craft to exceed the performance of its two-stroke Rotax-powered alternative, according to Tomazic. Pipistrel expands on this.  “Taurus Electro G2 can use a shorter runway, climbs faster and performs much better than the gasoline-powered version when it comes to high altitude operations. All this is possible thanks to the specially-developed emission-free Pipistrel 40kilowatt electric power-train.”  The clean sailplane design (40:1 glide …
