Pressure Distribution over the Rudder and Fin of an Airplane in Flight
This is a 1923 NASA technical report, issued by the NASA Technical Reports Server collection, presenting aerodynamic test results for aircraft designers and engineers. The pictures are plain line diagrams: sequences of rudder and fin cross-sections with pressure-distribution lines drawn over them at successive time intervals, plus a graph of control-surface angles, acceleration and air speed against time in seconds, useful for technical chart or diagram layouts.
