We’re still early in attempts to set world records with electric airplanes. Jean-Luc Soullier, a friend of the blog, held many of them a decade ago, flying a little Colomban MC-30, an ultralight designed by one of Concorde’s engineers. At the other end of the size scale, Solar Impulse set many records on its globe-girdling treks. Now, a five-member mostly German team hopes to set seven world records “in one fell swoop” as they electrically traverse 700 kilometers (435 miles) between the Schanis, Switzerland airport and Norderney Airport on Germany’s North Sea. Friends of Electric Mobility The five have interesting professional lives beyond their love of flight. “Futurologist Morell Westermann, Swiss pilot Marco Buholzer, the Norderneyer brewer Tobi Pape, the video and music producer Tom Albrecht and the podcaster Malik Aziz, who founded the association ‘Friends of Electric Mobility’ want to start on August 31,” according to Electric-Flight.eu. They will fly Pipistrel’s recently certified Velis Electro. The team adds, “Above …
etlantic to Tackle the Atlantic – Both Ways!
Having pushed his electric Colomban MC-30 Luciole (Firefly) to its limits and having won the Federation Aeronautique Internationale’s approval of his speed and altitude records, Jean-Luc Soullier and his team partner Roman Marcinowski are now after significant distance, speed and altitude goals. Needing a faster, lower-drag airplane to accomplish the next set of tasks, the etlantic Project turned to Greg Cole at Windward Performance in Bend, Oregon. Cole’s Duckhawk 15-meter sailplane outflew even 18-meter competitors in its first contest year. At a gross weight of 960 pounds (using the Windward specification), the special Duckhawk’s three-bladed propeller (special in itself) will have to overcome under 19 pounds of drag to maintain level flight at the best lift-to-drag speed. But the plan is to fly high and fast to set new world altitude and speed records. A lighter version of the base airplane, weight saved with thinner wing and fuselage skins, will allow carrying batteries and thin-film solar cells to power the …
Holding All the (Official) Records
If you go to the Federation Aeronautique Internationale web site, you’ll find only three officially ratified ratified records for Sub-Class RAL1E, Electric-powered Microlights with moveable aerodynamic controls. They all belong to Jean Luc Soullier and Luxembourg Spécial Aerotechnics – L.S.A., assisted by fellow members Martin Marschner von Helmreich, Fabrice Tummers and Roman Marcinowski, flying their Colomban MC-30 Luciole (Firefly). The F. A. I. made their February 2 flight achievements official just a few weeks ago. This small group developed the current power system with Electravia, and campaigned the airplane at Sisteron, France for these initial records. They plan on going higher, faster and farther, including a flight across a significant body of water. Jean Luc shared the following with your editor. “My culture is facts, no more no less. As we equipped the aircraft [with a] full set of recorders, positive difference was easy to see between before and after setting wing deturbulators: 20% of gain[ed] energy at constant speed …
Deturbulating a Record Flight
Sumon K. Sinha, Ph.D., P.E., and head of Sinhatech, had a part in the recent Federation Aeronautique Internationale (FAI) record by Mr. Jean-Luc Soullier and recorded in a blog entry on March 10. Dr. Sinha wrote that, “CAFE Foundation’s Blog on March 10th, 2012 did not mention that the Colomban MC-30 aircraft had Sinhatech’s Deturbulator tape treatment on the wing upper surface as shown in the attached photograph. I would like to have this added to complete the description of the aircraft.” Sinhatech Deturbulator tape is an innocuous-looking strip applied along the span of a wing at a point which will trigger a response from the tape, which oscillates in the airflow, increasing lift and mitigating skin friction, according to company white papers. Dr. Sinha points out that, “This is the first independently recorded flight with wing Deturbulator treatment by FAI. It is also the first independently recorded flight with full-span Deturbulators on a powered aircraft.” The Sinhatech web site …
New FAI Records for Electric Flight
Jean Luc Soullier of Belgium claimed three world records for electric aircraft in the FAI RAL1E (microlight electric, single place, landplane with moveable aerodynamic controls) sub-class on February 2, 2012 at Sisteron, France – home of Electravia. All three records are being scrutinized by the Federation Aeronautique Internationale. Soullier attained an altitude of 2,401 meters (7,877 feet), covered 50.27 kilometers (31.17 miles) over a closed circuit course without landing, and averaged 136.36 kilometers per hour (84.54 mph) for that distance. All records are claimed in Soullier’s Colomban MC-30 Luciole, powered by a Lynch-type motor and controller supplied by Electravia. These are not the MC-30’s or Soullier’s first records. He set a speed record on a 15 kilometer course with the airplane’s previous power system, and a few months later in 2011, set a speed record before the airplane’s sponsor, His Serene Highness Prince Albert II of Monaco while at the Aero Expo at Friedrichshafen. The official record was cancelled, however, …
