Jean-Marie Le Bris (* 1817 in Concarneau , † 1872 in Douarnenez ) was a French aviation pioneer , who in December 1856 his glider artificiel L'Albatros a glider is said to have performed.

Life

Jean Marie Le Bris was a seaman and sea captain who watched the albatrosses on his travels around the world . Although he sailed around the world, his passion was flying. He caught some birds and analyzed their wings in the air stream. He referred to aerodynamic take- off with the word aspiration .

Le Bris then built a glider that was derived from the shape of the albatross. He named the glider L'Albatros artificiel . His flight tests took place in December 1856 on the beach of Sainte-Anne-la-Palud in the Finistère department . The glider was pulled up against the wind by a running horse. The machine is said to have reached a height of 100 meters and flown around 200 m. During these first attempts, however, due to the insufficient control around the transverse axis, there was also a crash landing, in which Le Bris broke his leg.

Le Bris invented its own wing control, with which one could change the angle of attack of the wings. This innovation was part of his patent from 1857.

With the help of the French Navy , he built a second glider in 1868, the Albatros II . However, three attempts to start in Brest were unsuccessful, although the machine was lighter and had a weight transfer system. During an unmanned gliding attempt, the Albatros II crashed and suffered a total loss.

His Albatros II is the first aircraft heavier than air to be photographed. A picture marked PÉPIN fils, Phot shows Le Bris and the machine on the ground in 1868.

Mount Bris , a mountain in Antarctica, is named in honor of Le Bris .
