 | | |  | | Like their aircraft and engines, the Wrights' 1901 wind tunnel was developed in stages, through a series of variations and experiments. The challenge of creating reproductions of these pioneering instruments is that they exist only in descriptions - the Wrights did not preserve them. | | |  | | Bicycle experiment: The Wrights' cycles were their first airfoil testing platform. | | |  | | Tunnel development: The fate of the original tunnel is unknown. Fortunately, there was nothing really special about it. Surprisingly, this was part of its design. | | |  | | The fan: A lost component of the tunnel, this reproduction actually benefits from the Wrights' work. | | |  | | The airfoils: The critical models for the experiments. | | |
