Investigation of Jet Effects on a Flat Surface Downstream of the Exit of a Simulated Turbojet Nacelle at a Free-stream Mach Number of 1.39
This is a NASA technical report from 1956 on jet effects over a flat surface behind a simulated turbojet nacelle at Mach 1.39, written for aerodynamics engineers and researchers. The pictures are plain engineering charts: pressure-coefficient curves against distance ratios, and scatter plots of shock-wave angles against pressure ratios, drawn with open symbols on gridded paper and annotated with nacelle and wing sketches. A designer might borrow their clean, sparse diagram style, with grid backgrounds, small circular data markers, and simple line-drawn schematics of a jet nacelle beneath a wing.
