Pipistrel’s Panthera Pounces

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

Aero, in Friedrichshafen, Germany gets a little more electric every year, with one of this year’s highlights being Jean-Luc Soullier’s flight in his Colomban MC-30 E, setting records for speed and altitude in its class. Another highlight, for a very different class of aircraft, was the unveiling of the Pipistrel Panthera – made even more exciting by the company’s decision to create three powerplant options for the airplane – an internal combustion IO-390 powered speedster, a hybrid engine/motor cruiser, and a battery powered electric version that essentially gives up performance for economy.  The airplane was shown only in large model form at the company’s announcement, but Pipistrel has provided full performance data, an attractive brochure (see the site above), and a full price list, the last through their American distributor.  The laws of physics giveth and the laws of physics taketh away.  The traditional engine-powered Panthera gives the greatest performance, but uses the greatest amount of fuel.  The hybrid version is …

ElectraFlyer’s Near Future Plans

Dean Sigler Uncategorized 3 Comments

ElectraFlyer’s Randall Fishman and Embry Riddle Aeronautical University were the lone inhabitants with aircraft on hand at the “green aviation” display at Sun n’ Fun, exhibiting the modified Stemme and the ElectraFlyer “C” respectively.  Having been within a few displays’ distance from the Thursday tornado that destroyed 69 aircraft, damaged many others, and dismantled marquees all around, they were probably fortunate to be there at all. Having decided to leave his two-seat ElectaFlyer X back at the shop, Randall had his four-year-old ElectraFlyer on hand, an airplane which hides what he describes as the only currently available electric motor, controller, instrumentation, custom propeller hub, and battery package in its neatly cowled nose, and which has been available for years before Yuneec and Pipistrel announced their systems.  He avoids the term, “Plug and Play” because he’s wary of using connector plugs to carry high amperage and high-frequency between the motor and controller, preferring battery cable lugs and bolts for secure connections. …

A professor and student at the Technical Superior School of Industrial Engineering and Aeronautics of Terrassa (ETSEIAT), part of the Politechnical University of Catalonia (UPC), have unveiled a radio-controlled car that runs on aluminum soda pop can rings, water and vinegar. Professor Xavier Salueña and his student, Aleix Llovet, held an April 14 press conference concerning dAlH2Orean, part of the project called “Aluminium,” for the manufacturing of micro cars with 5-60 horsepower using recycled aluminum as their primary fuel.  The miniature vehicle’s propulsion system has been patented.  The car can run on aluminum soda (or beer) can rings, “or residual parts of aluminum with hydroxide of sodium (which acts as a catalyst) dissolved in water,” according to its developers.  “The whole operation is based on the self-generation of hydrogen created by the reaction between aluminum and sodium hydroxide.  This self-generated hydrogen feeds the fuel cell that produces the energy,” according to the team’s press release. “The residue of aluminum and …

To prepare Solar Impulse and its pilots for the upcoming airshow season, André Borschberg and other members of the flight team completed a series of tests to enable precise flying, particularly around the Paris Air Show at Le Bourget. “We are preparing for these trips beforehand because they are very complex operations, from both a logistical point of view and purely in terms of flying”, Borschberg explained following his three-hour flight on April 18. Solar Impulse will be the “special guest” at the Paris Air Show at Le Bourget from June 20 through 26. This last week’s tests were designed, according to acting flight test director Ralph Paul, with “two objectives…: to adopt the Bourget configuration and increase the flight envelope by doing stickraps.” As the project’s blog explains, “The solar airplane made three simulations closely modeled on the choreography to be adopted for the presentation flights in Paris…. Initially, the pilot climbed to an altitude of 1000 feet (a …

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

The town of Ulm, Germany holds an annual Berblinger Prize competition to honor the memory of the Little Tailor of Ulm, Albrecht Berblinger, who attempted to fly an early hang glider across the Danube in 1811.  This 200th anniversary year has been marked by special celebrations, including an ambitious aerial challenge for “green” aircraft. 36 applicants were pared to 24 participants in the actual flight competition, and on April 15, a mere 13 started on the flight between Friedrichshafen and Ulm and return.   Eight were able to complete the exercise, according to contest officials.  The rest were unable to compete or finish, “due to insufficient financial backing, technical difficulties or the absence of the appropriate flying licenses the remaining competitors were not able to take part in the practical phase of the competition.” Judging criteria overseen by an “independent jury comprising experts from the aerospace industry, representatives of universities and research institutes, aviation historians and representatives of the town of …

A Trio of Winners at Friedrichshafen

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

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 Families of Flight gathering, LEAP garners a great deal of recognition for its prize winners. LEAP gave three awards at Aero 2011.  In the best electric airplane category, the judges chose three finalists: • The Hugues Duval Electric Cri-Cri with …

Phoenix or PhoEnix – a Nice Airplane

Dean Sigler Electric Powerplants, GFC, Sustainable Aviation 3 Comments

While at Sun n’ Fun in Lakeland, Florida, we couldn’t help but notice Jim Lee’s Phoenix Air Phoenix, an S-LSA (Special Light Sport Aircraft) motorglider from the Czech Republic, posed as it was on the line of march into the air show area proper. Your editor was interested in the PhoEnix, the electric version of the proper looking and highly attractive Rotax-powered version in the Light Sport Aircraft display display, next to its Pipistrel neighbors.  There were a great many middle European LSAs being shown, but the Phoenix had ended up on the Airshow’s promotional poster, neatly avoiding the FA-18s of the Blue Angels. The electric version will be competing in the Green Flight Challenge, so revelations from Jim Lee, the airplane’s U. S. distributor and pilot in the GFC, were the usual furtive responses to detailed questions.  All competitors are being careful to avoid revealing too much until after Larry Ford’s presentation at the fifth annual Electric Aircraft Symposium in …

The Electric Firefly Sets Two World Records

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Jean-Luc Soullier has converted Michel Colomban’s two-cylinder internal combustion MC-30 Luciole (Firefly) into an electric aircraft – not without some teething problems, but with plenty of promise.  His group, LSA, Luxembourg Spécial Aerotechnics, consists of Jean-Luc, Martin Marschner von Helmreich, and Fabrice Tummers – and has terrific ambitions. Fabrice, in response to questions about the record attempts, sent the following: “Our target in 2011 is to realize the totality of the world records of the F.A.I. in the category RAL 1E, and cross the Mediterranean Sea.  The first attempt [a speed record] was not ratified by the F.A.I. but the medium speed recorded was 160 kilometers per hour (99.4 mph) over 15 kilometers. (9.3 miles)” With the 118 pounds of batteries now on board, the airplane has more than one hour endurance, but a proposed switch to hydrogen fuel cells will allow six-hour flights and make Mediterranean crossings a breeze.  If the team can keep the motor and controller cool.  Reports …

Lindy Hop to Lindbergh LEAP

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

Sun n’ Fun, following a disastrous sweep by an F1 tornado through the flight line on Thursday, March 31, came back strong the following day, with F-22 demonstration flights, the Blue Angels, and a full contingent of top-drawer aerobatic pilots. The Green Aviation exhibits your editor had hoped to visit were partly gone, tents and exhibits having been dismantled and carted away in the remarkable overnight cleanup effort that took place, but the Embry Riddle Aeronautical University (ERAU)/Lindbergh Electric Aircraft Prize (LEAP) Stemme S-10 gleams undamaged in the sun.  Lisa Costello, a graduate student in aeronautical engineering, explains some highlights of what the students are crafting.  Entered in the upcoming Green Flight Challenge, the S-10 was to use a combination of hydrogen fuel cells and lithium batteries for motivating an electric motor.  That hybrid has been replaced by a Flight Design/Rotax hybrid that combines a 100 horsepower engine with an electric motor for power.  Lisa suggests we go to a nearby …

“Mishap” to AeroVironment Global Observer

Dean Sigler Electric Powerplants, Sustainable Aviation Leave a Comment

It wasn’t an April Fool’s Day joke, even though AeroVironment’s press release is dated April 1.  Their Global Observer crashed in the Mojave Desert during extended duration flight testing.  AeroVironment stressed that there were “No injuries or damage to other property reported during envelope expansion flight testing,” and that an “Investigation Board will be convened to probe the cause and provide details of the mishap.” The mishap occurred at 2:30 a. m., approximately 18 hours into the craft’s ninth test flight.  AeroVironment’s press release continues, “’Flight testing an innovative new solution like Global Observer involves pushing the frontiers of technology and convention,’ said Tim Conver, AeroVironment chairman and chief executive officer. ‘Risk is a component of every flight test program, and the learning that results from a mishap enables us to improve system reliability and performance. One benefit of testing an unmanned aircraft system is that pilots and crew are not in harm’s way when a mishap occurs.’” The flight test team, …
