Calculation of potential flow past airship bodies in yaw
This NASA technical report from 1932, a calculation of potential flow past airship bodies in yaw, was prepared for aeronautical engineers and researchers studying airship aerodynamics. Its pictures are line graphs of calculated functions, geometric sketches of a streamlined ovoid body with coordinate axes, and a labelled cross-section diagram of normal and tangential force vectors, all drawn in plain black linework that a designer could borrow for technical diagram style or minimalist schematic layouts.
