Tests of Nacelle-Propeller Combinations in Various Positions with Reference to Wings V : Clark Y Biplane Cellule - NACA Cowled Nacelle - Tractor Propeller
This is a 1935 NACA technical report from the NASA Technical Reports Server, testing how a cowled engine nacelle and tractor propeller perform when mounted at different positions on a Clark Y biplane wing cellule. Its photographs show wind-tunnel models with the nacelle moved through a series of positions, while its charts plot pressure contours around the wing. A designer might take from it the striking grid-and-strut tunnel photos and the clean contour line drawings as examples of engineering diagrams.
