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 200 Km/h (124 mph) – Distance : minimum 2,000Km ( 1,250 miles ) (This will probably be accomplished with the Duckhawk.) – Altitude : minimum 10,000 meters ( 32,800 Ft ) (Again, probably with the Duckhawk, although Roman says, “let’s see what …
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 …
