Flight Measurements with the Douglas D-558-II (buaero No. 37974) Research Airplane : Measurements of Wing Loads at Mach Numbers up to 0.87
This is a 1950 NASA technical report, issued by NASA's Technical Reports Server, recording flight tests of the Douglas D-558-II research airplane for engineers studying wing loads at speeds up to Mach 0.87. The pictures are plain black-and-white line graphs with hand-plotted data points, scattered circles, fitted curves, and NACA logo corner labels on axes of coefficient against angle or Mach number, offering a designer little beyond the stark grid-and-plot vocabulary of mid-century engineering documentation.
