Wing-Nacelle-Propeller Tests - Comparative Tests of Liquid-Cooled and Air-Cooled Engine Nacelles
This is a 1934 NACA technical report from the NASA Technical Reports Server, comparing wind-tunnel results for liquid-cooled and air-cooled engine nacelles mounted on a wing. Its pictures are engineering drawings: side profiles of nacelles on a thick wing, cross-section circles with dimension callouts, and line graphs of lift and drag coefficients. A designer might take from them the clean streamlined nacelle silhouettes and the precise dimensioned cross-sections of aircraft engine housings.
