Wind Tunnel Studies in Aerodynamic Phenomena at High Speed
A 1921 report from the National Advisory Committee for Aeronautics, issued through NASA's Technical Reports Server, presenting wind tunnel studies of aerodynamic phenomena at high speed for engineers and researchers. The pages are engineering drawings: a wind tunnel plan with a circular test section, a ring of radial vanes or struts, and a propeller blade shown in plan and section with its airflow arrows. A designer could take from them the crisp hatched line work, dimension lines and technical plate layouts typical of early aeronautical reports.
