The estimation of the rate of change of yawing moment with sideslip
This is a 1938 NACA technical note from the NASA Technical Reports Server, a government aeronautical research report on estimating yawing moment change with sideslip for aircraft. It is written for aerodynamicists and aircraft engineers, and the pictures are its line graphs of test data and line drawings of flying-boat models. For a designer the pictures offer plain engineering charts with grid lines and marker symbols, and simple side-profile drawings of seaplane hulls, useful as clean schematic references.
