Summary

Commemorative plaque, Laboratoire Aérodynamique Eiffel, 67 Rue Boileau, Paris 16th.
Historical Mechanical Engineering Landmark.
Eiffel 1903 Drop Test Machine and 1912 Wind Tunnel.
Gustave Eiffel (1832-1923) began aerodynamic testing by dropping various body shapes attached to a drop test machine guided by a vertical cable suspended from the Eiffel Tower. This machine measured and recorded the drag of the bodies and the drop velocity. It was the most advanced device of its type.
Eiffel built his first wind tunnel beside the Tower in 1909. By testing the same bodies he had drop tested, Eiffel validated the concept of relative motion.
The 1912 wind tunnel of Auteuil featured an open jet of air within a closed test chamber and introduced a downstream diffuser. This innovation, patented in 1912, improves the efficiency of the "Eiffel aerodynamic system" whose features were emulated in many later tunnels.
The Auteuil laboratory is the most complete early aeronautical laboratory in existence and still in operation.
