Effect of Jet-nozzle-expansion Ratio on Drag of Parabolic Afterbodies
This is a 1954 NASA technical report on how jet nozzle expansion ratio affects drag on parabolic afterbodies, produced for aeronautical researchers. Its pictures are plain black-and-white line drawings with dimensioned profiles, a wind tunnel test section, and a probe and orifice rig, useful to a designer for their clean technical diagram style, labelled callouts, and streamlined body contours.
