Life

Vein was the son of François Ader and his second wife Antoinette Forthané. Vein has performed with his Éole the first ( uncontrolled ) powered flight in history, but which ended with a crash. He also improved the telephony through the vein 's telephone and by a further development of the carbon microphone. 1880 Core installed in Paris, the first phone line, a year later, he presented with the Théâtrophone a work based on the core 's phone system for stereophonic transmission of music performances before.

In the German - French War Core built during the Siege of Paris 1870/71 at its own expense one of the balloons that were once used to break the siege.

Artery led (German "airplane" ) in the French language the word Avion. While it is sometimes thought of as an acronym ( " mimics flying machine, the natural birds ' dt ) for the Appareil Volant Imitant les Oiseaux Naturels is, it is probably freely around a portmanteau, the wire from the Latin word avis (Eng. " bird" ) is derived. In the construction of Éole vein, however, had taken the construction of the wings of bats as a model and copied to the last detail. The wings of his designs could be on the ground to exactly fold the same way as bat wings.

When Éole it was a cantilevered flying wing monoplane, which should be driven by a force acting on a four-leaf propeller 4-cylinder steam engine of 20 hp and controlled by twisting the wing and a rudder -like back -drawn, fabric-covered fuselage section. The Éole took off for its single flight on October 9, 1890. After a journey of about 50 m the Éole crashed and was destroyed on impact.

Artery was initially supported by the French government. Due to a crash at the screening of his Éole III, which is only 300 meters wide and 20 inches high flew to statements of an expert opinion officer, and his opinion that developments spreader would end in a technical cul de sac, the support was withdrawn. Ader Éole III was approximately 1900 publicly exhibited in Paris. Core published in 1910 a description of his attempts.

At the age of 84 years Clément Ader died on May 3, 1925 in Toulouse. The grounds of the Airbus factory in Toulouse Saint -Martin was named in memory of vein " Clément- Ader factory " ( " L' usine Clément Ader ") and the main hall for the assembly of the aircraft, " Clément- Ader Hall".
