The Torsional and Bending Deflection of Full-Scale Duralumin Propeller Blades under Normal Operating Conditions, Special Report
A 1938 NACA-style technical report on the torsional and bending deflection of full-scale duralumin propeller blades under normal operating conditions, issued by the NASA Technical Reports Server collection for aeronautical engineers and researchers. The pictures include an airfoil-body force diagram with labelled axes, a plan-view wind tunnel schematic with light source, mirror and screen, and a graph of bending, torsional and flutter deflection curves plotted on a grid, offering a designer little beyond engineering diagram conventions such as labelled axes, dashed flow lines and plotted curves.
