Influence of fuselage on propeller design
This is a 1928 NASA Technical Reports Server report on how an aircraft fuselage affects propeller design, issued as an aeronautical technical memorandum for engineers and aircraft designers. The two plates show a velocity-vector diagram with labelled angles and a fuselage dimension table beside a side-view drawing, and a graph of a dimensionless ratio plotted against a fraction from 0 to 1 with two curves and arrows. A designer could take the clean line diagrams and plotted curves as examples of simple technical figure layout.
