Ground-cooling and Flight Tests of an Airplane Equipped with a Nose-blower Engine Cowling
This 1939 NACA technical report, issued by the National Advisory Committee for Aeronautics for engineers and aircraft designers, documents ground-cooling and flight tests of a nose-blower engine cowling fitted to an airplane. The photographs are plain black-and-white views of an A-17A-type monoplane shown from the front, side and three-quarter angles, with close-ups of the cowling, propeller and air inlets, useful as reference for streamlined aircraft nose forms and engineering diagrams.
