The Effect of Cowling on Cylinder Temperatures and Performance of a Wright J-5 Engine
A 1930 NASA technical report, issued through the NASA Technical Reports Server, presenting test results on how engine cowling affects cylinder temperatures and performance in a Wright J-5 aircraft engine. Its pictures are dense polar charts with concentric rings, radial gridlines and looping traced curves, plotted for several cowling configurations and airspeeds, which a designer might borrow as precise, technical diagram texture.
