Georges Darrieus

from Wikipedia, the free encyclopedia

Georges Jean-Marie Darrieus (born September 24, 1888 in Toulon , France , † July 15, 1979 ) was a French engineer.

Life

Georges Darrieus was born as the son of Vice Admiral and Gymnote Commander Gabriel-Pierre Darrieus (1859–1931) and his wife Eugénie. Brun born. After attending school at the Collège Stanislas and the Lycée Janson de Sailly in Paris , he studied at the University of Toulouse and at the École Centrale Paris , where he obtained an engineering degree. From 1912 to 1958 he worked as an engineer for the French locomotive manufacturer Compagnie Electromécanique, only interrupted by the First World War , in which he served as an artilleryman.

On December 2, 1946 Darrieus became a member of the Académie des sciences , 1947 President of the Société française des électriciens , 1952 of the Société des Ingénieurs civils de France and 1955-58 of the Société d'encouragement pour l'industrie nationale . He received the Croix de guerre 1914-1918 and was commander of the Legion of Honor .

Darrieus was married to Germaine Brest and had six children: Cécile, Jean, Madelaine, Yves, Geneviève and Odile.

Working as an engineer and inventor

Patent sketch of the Darrieus rotor

Darrieus did research in the field of ballistics , fluid dynamics ( turbines , compressors , aviation ), thermodynamics and electrical engineering .

On August 25, 1931, he received a patent for a horizontal rotor with flat blades for operation with the most constant speed and torque possible with changing flow rates of the medium. A first patent for a wind turbine with a vertical axis followed in October. A 20 meter high system of this type was built two years later, the type of construction is now known as the Darrieus rotor . In the field of wind turbines, Darrieus also received a patent for a specific streamlining, for a “device for automatic balancing of rotating machine parts” and for various protective devices.

Other patents are partly related to the question of how turbo rotors or turbo generators of wind turbines can be improved or relate to specific components such as the stator lamination body suspension. In addition, many patents generally relate to the generation or distribution of electrical energy, including electrical protection systems or improved high voltage pylons.

In 1937, together with the Théorème de Darrieus , he formulated the conditions that guarantee optimal transfer power frequency control in interconnected networks .

In the field of fluid mechanics, Darrieus had a pressure exchanger, a compressor and a gas / fluid separation device patented.
