Propeller design: extension of test data on a family of model propellers by means of the modified blade element theory II
This is a 1926 NASA technical report, issued through the NASA Technical Reports Server, on propeller design that extends test data from a family of model propellers using modified blade element theory. Its pictures are engineering charts and drawings rather than illustrations: plotted curves of lift and efficiency against blade radius, camber and chord distributions, and a blade-section path view with front and side elevations. A designer could borrow the clean, technical graph and grid vocabulary, the labelled curve families, and the plan-and-elevation drawing layout.
