Corrugated metal diaphragms for aircraft pressure-measuring instruments
A 1939 NACA technical note from the National Advisory Committee for Aeronautics, issued in the United States, on corrugated metal diaphragms for aircraft pressure-measuring instruments, written for engineers and instrument makers. The pictures are graphs of deflection against pressure for several diaphragm shapes, a log-style chart comparing diaphragm types, and photographs of machined corrugated metal discs with concentric rings, which a designer might take as a study of ringed, concentric geometry in engineered objects.
