Soullier’s Record – And One You Might Set

Dean Sigler Electric Powerplants, Sustainable Aviation 0 Comments

At least one of the records Jean-Luc Soullier had hoped for came true during Aero 2011 at Friedrichshafen in early April.  Officially validating the speed record, the Federation Aeronautique Internationale has yet to recognize the altitude record achieved during the same flight. Soullier’s MC-30 Luciole (Firefly) had a royal Sponsor, His Serene Highness Prince Albert II of Monaco observing while Jean-Luc flew a 15/25 kilometer (9.3/15.5 miles) straight-line course out and return at 135 kilometers per hour (83.7 mph), winning the RAL1E subclass speed record for microlights. Several subclasses exist for one and two-seat electric microlights – few of which have recognized records, and thereby becoming an opportunity for early adapters of battery-powered, fuel cell or hybrid flight.  These “empty” subclasses are a golden opportunity for those willing to provide …

The Electric Firefly Sets Two World Records

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 …

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 …
