This full-scale wind tunnel fan was one of a pair built by the National Advisory Committee for Aeronautics (NACA, the predecessor to NASA) in 1931 and used at the Langley Research Center in Hampton, VA to test aircraft and spacecraft. It is now on display at the museum in Washington, DC, in the “Boeing Milestones of Flight Hall.”
