System Analyses and Autopilot Design for Automatic Roll Stabilization of a Supersonic Pilotless Aircraft
A 1951 NACA technical report from the NASA Technical Reports Server on system analyses and autopilot design for automatic roll stabilization of a supersonic pilotless aircraft, written for engineers and aeronautical researchers. Its pictures are plain engineering charts: a Bode-style gain and phase plot on semi-logarithmic grid paper, and polar-coordinate plots on circular grids with handwritten annotations, pencilled labels and marked curves. A designer might take from them the restrained, grid-based graphic language of technical diagrams, with fine rules, faint lines and small handwritten notes.
