NACA Cowling #10
Description Drag can present a major problem for aircraft and much of Langley Lab's early research was focused upon reducing aircraft drag. One method was to place a cowling or covering over the engine cylinder heads, much like the hood over the engine of a car. By the end of September 1928, tests of cowling #10 in the Propeller Research Tunnel showed a dramatic reduction in drag. This research won the NACA the first of its many Collier Trophies.
