NACA Aids Air Power Through Langley Tests and Wind Tunnels
The 1915 act creating the National Advisory Committee for Aeronautics established a lasting advisory body to aircraft makers. Langley Field's Langley Memorial Aeronautical Laboratory, the oldest center, conducts wind tunnel tests exceeding 500 mph and fixes performance issues. A notable experiment studied power impact on spray as a seaplane moves at 11 feet per second using a powered model and three photos illustrate the effect when gas is applied.
