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 …

Going After New Records and New Adventures

Already holder of all the Federation Aeronautique Internationale (FAI) world records for light electric aircraft, Jean-Luc Soullier of AeroSkyLux has announced his latest endeavor, the Etlantic Project.  Since he achieved these records in a microlight MC-30 with a Lynch-type Electravia motor, he has searched for a higher-performance airplane and power system.

Academy Award Winner, Legion of Honor Recipient Conquer the Channel

Anne Lavrand, head of Electravia, shared this news in her blog this morning. Following its initial flight at the Coupe Icare in 2011, the electric airship Iris Challenger was slated to make a cross-English Channel attempt later that year. Unfortunately, prevailing winds prevailed against that November attempt between Dover and Calais. Patience and careful planning finally paid off for pilots Pierre Chabert and Gerard Feldzer, though, and today, they made the crossing from France to Dymchurch, England in two hours and 23 minutes. Built by Airstar (Chabert is founder and president/CEO of the company), the envelope contains 568 cubic meters (20,059 cubic feet) of helium, and can carry a payload of 200 kilograms (440 pounds). Equipped with two electric motors …

Would You Believe There Are Four Electric Cri-Cri’s?

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Three electric MC-15 Colomban Cri-Cri’s have been flying for at least the last two years.  Jean-Luc Soullier created one which flew with Plettenberg model motors.  Airbus crafted one with four Rotex motors and counter-rotating propellers on each mount.  Anne Lavrand’s Electravia converted a Cri-Cri to use her motors for speed record attempts. Now they are joined by the MC-15E built by Mr. Toon Jacobs and shown at the Federation RSA ( Network of Sport Air ) Rally 2013 in Vichy, France.  The RSA, as one would guess, is the French equivalent of America’s Experimental Aircraft Association (EAA). Electravia provided the E-Motor GMPE 104 motors, controllers, E=Helices 370 gram (one pound, 13 ounces), 83 centimeter (32.7 inches) propellers and the E-Batts 3 kilowatt-hour battery pack.  An Electravia …

eUP Looks Up and Downloads Data

John McClintock, co-founder of eUP Aviation in Lumby, British Columbia, recently spoke with your editor on changes he and Randy Rauck are making to their Electravia-powered hang-glider trike.  They’ve recently campaigned Green1 up and down the Pacific Coast, demonstrating its self-launching and soaring capabilities over California deserts, at Torrey Pines, and in the mountains of Oregon. John was pleased to report that the trike came through that 7,700 kilometer (4,774 mile) bouncing trailer torture test with a perfect bill of health for the e-drive system and its installation. Not content to just enjoy their flights (which they did) the entrepreneur-engineers kept careful records of the details of each flight using an on-board Flytec 5030 hang gliding instrument to collect flying …

Navette Brettone Carries On

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

The April, 2013 issue of Info.Pilote magazine, a French publication, features the air-show pairing of the electric Cri-Cri E-Cristaline, powered by two Electravia GMPE 104 motors and riding atop a Broussard – what the DeHavilland Beaver might look like if it had been built in France. The great photos by Jean-Marie Urlacher are supplemented by a dynamic video showing a typical airshow lofting and separation – something that happens quickly even in slow motion. Info.Pilote has an informative table comparing the Navette Brettone (Brittany Shuttle), named for the sponsoring ferry boat operation, with the Navette Spatial, our space shuttle/Boeing 747-100 combo. While the big Boeing spans 196 feet, the Broussard is a relatively petite 45 feet.  The Space Shuttle riding …

Reanimating a 30-Year-Old Canard with an Electrical Charge

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

The CC01e, a tiny, single-seat canard design by Frenchman Claude Chudzik, flew for the first time in 30 years years, now powered by an Electravia-supplied motor system.  Taking off from Nangis airport, team member Frederic Laude gingerly guided the airplane on its single circuit of the field. He reported some tendency to “marsouine,” or porpoise, of which he’d been forewarned, and managed to keep the pitch oscillations in check.  Based on the team’s report on their blog, he accelerated to 60 knots (69 mph), pulled lightly on the stick and “jumped” off the runway.   You can see the porpoise-like bobble immediately after lift-off, and Frederic’s ability to get things under control quickly.  Once on track, he reached 94 knots (108 …

Can You Top These?

Anne Lavrand of Electravia  sends news that Jean Luce Soullier’s speed record set last September has been ratified by the Federation Aeronautique Internationale (FAI).  He now holds four FAI world records, and Ms. Lavrand’s total climbs to five, including the speed record set by Hugues Duval flying the MC15E twin electric Cri-Cri down Le Bourget’s main runway at 283 km./hr. (175.46 mph) during the 2011 Paris Air Show.

A Fix for Dreamliner Battery Woes?

Dean Sigler Electric Powerplants, Sustainable Aviation 1 Comment

With Boeing facing financial doldrums because of its ongoing grounding and resulting slump in sales of the 787 Dreamliner, the stakes are high for the company.  That makes today’s Reuters’ report that the manufacturing giant may have found a “way to fix battery problems on its grounded 787 Dreamliner jets” good news for not only Boeing, but for electric aircraft in general.  Readers should read these findings with some caution, though, since another report from Japan gives a different possible cause for the problems.  That said, the two reports might not be mutually exclusive. Many electric light aircraft developers use spacing between cells and some method to circulate cooling air over them.  In Boeing’s two 787 lithium battery packs, eight …

Fifth Anniversary for Electravia Ultralight’s First Flight

Dean Sigler Electric Powerplants, Sustainable Aviation 2 Comments

Anne Lavrand, founder and head of Electravia, has over 35 different electric aircraft to her credit, having powered everything from paramotors to a world speed record-holding Cri-Cri  and a speed and altitude record-claiming MC-30. The story officially began five years ago today, though, with a 48-minute flight by an ultralight Souricette, a Michael Barry design with an Electravia-prepared Lynch brushed motor, golf-cart type controller and lithium polymer batteries . In an article from The Times of London, it was given credit as the, “First flight in a conventional light aircraft powered by an electric motor,” and as such a model of frugality.  Barry’s airplane, motor, and batteries might set an owner/builder back 10,000 to 15,000 euros ($13,000 to $19,500) and …
