Description

English: Drag can present a major problem for aircraft and many of Langley'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 PRT showed a dramatic reduction in drag.
