Wind tunnel
A wind tunnel is a system for testing aircraft or airfoils in controlled conditions by creating your own airflow. Typically, the test object is placed in the middle of a tunnel and a source generates wind.
Francis Herbert Wenham is credited with building the first wind tunnel, in 1871, after unsuccessful efforts to accomplish the same goal with a whirling arm.[1]
The French military establishment at Chalais-Meudon had the first wind tunnel in France. Later, Nikolay Yegorovich Zhukovsky (or was it Konstantin Tsiolkovsky?) built the first one in Russia. Horatio Frederick Phillips built one (the first?)
Wind tunnels were used to refine the theoretical understanding of aerodynamics and to test out the theories on different airfoils and vessels. The Wright Brothers used a small homemade tunnel to test out different aircraft designs in 1901.
It seems that Gustave Eiffel created an alternative method (called by Lucien Marchis the "Eiffel method" as opposed to the "tunnel method") using a larger chamber in which
The apparatus employed for determining the circulation of the air is enlarged into a chamber of suitable size, traversed between two of its parallel walls by a cylinder of moving air. On the outside of the latter and within the chamber are located the experimenters with the necessary measuring apparatus.[2]
It is not clear that there were any Japanese wind tunnels of significance before 1920.
