Tests for the Elimination of Tail Flutter
This is a 1933 NACA technical memorandum, issued by the National Advisory Committee for Aeronautics, that reports wind-tunnel and flight tests aimed at eliminating tail flutter on aircraft. The plates are rotated photographs and line drawings of airframe surfaces, tail units and airflow patterns, intended for engineers studying aerodynamic test results. A designer might take from them the sharp diagonal shadows, the close-up oblique views of riveted metal and fabric skins, and the schematic flow-line diagrams.
