Navy propeller section characteristics as used in propeller design
A 1926 technical report from the NASA Technical Reports Server, compiling Navy propeller section characteristics for propeller designers. Its single picture is a dense engineering graph plotting lift coefficient against camber for a family of curves labelled by angle of attack, with the grid and axis labels reading as precise measured data. A designer might borrow its restrained, gridded chart style for technical diagrams, with thin black curves fanning across a pale ruled field.
