Summary
This artifact is from a collection of propellers used by Professor David L. Gallup in 1911 experiments conducted at the Alden Hydraulic Laboratory of the Worcester Polytechnic Institute in Worcester, Massachusetts.
The Gallup whirling arm experiments were one of the first comprehensive attempts to test the efficiency of propellers in the world. In 1912 the same testing apparatus was used by MIT student Frank W. Caldwell, who went on to become a leader in the development of propeller technology in both government and industry.
