Firefly Flies with New Motor and Who Knows What Else?

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Jean-Luc Soullier and Roman Marcinowski forge ahead on two fronts to set electric flight records.  Longer term, we hope to see first flights of their motorized Windward Performance Duckhawk, modified for long-distance flights and a crossing of the Atlantic Ocean – perhaps as early as next year. In the meantime, they are putting the finishing touches on their already record-setting Colomban MC-30 Luciole (Firefly), now with its third motor, significantly larger and more powerful than previous powerplants.  Making an initial test flight on October 30, Jean-Luc managed an impressive climb rate, even at partial power. Last year, the team stated their hoped-for records to come. Our next targets are : Spring/Summer 2014 New FAI world records : – Speed : minimum …

EAS VIII: Across the Atlantic – Twice

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

Jean-Luc Soullier, holder of Fédération Aéronautique Internationale records for speed and altitude in an aircraft almost lighter than its pilot, has a greater series of ambitions to expand the range and speed of electric aircraft. Having stretched the limits of his Colomban MC-30e with two different motors, he’s looking at a longer-spanned, cleaner aircraft – the Windward Performance Duckhawk – as a means of getting higher speed and much longer range for a truly formidable (tres formidable) crossing of the Atlantic Ocean, not once, but twice. The airplane, with a Rotex motor on the nose and a specially-designed Arplast three-bladed propeller, will weigh a mere 105 kilograms (231 pounds) empty – without batteries. This is considerably less than the lightest …

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 …

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 …
