The limited capacity of the available measuring instruments, led M. Eiffel to a more sophisticated knowledge in aviation and, eventually, to wind tunnel experiments. He built a wind tunnel on the Champ de Mars, which was in use from 1909-1911. The tunnel was sufficient for lab experiments bit inadequate for the study of airplanes. However, with the help of several other engineers, Leon Rith, Lapresle, and Eiffel made over 5,000 tests in this lab. Almost all the pioneers of aviation tested in this wind tunnel. |
