   The main purpose of the Propeller Research Tunnel was researching the aerodynamic efficiency of propellers on radial engine aircraft. In 1917, William F. Durand published NACA Technical Report 17 on his work with isolated propellers in Stanford University's wind tunnel, however these results did not match with the data NACA had collected for propellers connected to fuselages.
