Tests of Nacelle-Propeller Combinations in Various Positions with Reference to Wings VI : Wings and Nacelles with Pusher Propeller
This is a 1935 NACA technical report, issued by the National Advisory Committee for Aeronautics as a wind-tunnel test study of nacelle and propeller arrangements on wings with pusher propellers. Its pictures are black-and-white photographs of a model nacelle mounted on a wing strut in a wind tunnel, shown at numbered positions, with the propeller disc visible at left in the large view. A designer might take from them the clean, dense photographic style of engineering documentation and the way a repeated numbered sequence presents a single subject in comparison.
