A simplified application of the method of operators to the calculation of disturbed motions of an airplane
This 1937 NACA technical report, issued by the National Advisory Committee for Aeronautics and preserved through the NASA Technical Reports Server, presents a simplified operational method for calculating disturbed motions of an aircraft for engineers and aerodynamicists. Its two figures are plain engineering diagrams: a vector and locus plot with labelled logarithmic and exponential axes, and a set of small graphs of exponential decay and rise curves labelled with equations, offering a designer clean, schematic line-chart vocabulary.
