A study of longitudinal dynamic stability in flight
This 1924 NACA-style technical report on longitudinal dynamic stability in flight, drawn from NASA Technical Reports Server records, presents test data as line graphs of damping and oscillation period against airspeed in miles per hour for various engine speeds in revolutions per minute. Its plots of periods to damp to half amplitude and elevator angle against airspeed offer a designer a clear, sparse model for scientific graph layout, with fine curves, labelled trend lines and minimal decoration.
