Eiffel Aerodynamics: A breathtaking laboratory by Bertrand GARDEL

While we are going to celebrate the centenary of the disappearance of Gustave Eiffel, who would imagine that a laboratory, created by the brilliant engineer in 1912, could cross the century until reaching us in perfect working order. And yet, this is indeed the case with the wind tunnel located in the Auteuil district of Paris, which testifies to Eiffel's pioneering talent in terms of aerodynamics. Whether in the fields of aviation, automotive or architecture, the applications and research carried out using the laboratory's test resources are numerous. The wind tunnel, an "old lady" built of wood and covered with canvas, makes it possible, for example, to measure the drag forces and pitching problems of an aircraft, to measure the capacity of a building to resist the wind or to limit the appearance of sound disturbances related to the friction of the air on the materials of a facade Faced with the challenges of global warming, the addition of the latest technologies allows the laboratory to be useful in the creation of positive energy eco-districts in hot regions, in particular by making it possible to reduce energy consumption through better circulation of air. 'air . Ventilate naturally rather than air conditioning.
