Effects of a Simulated Ice Formation on the Aerodynamic Characteristics of an Airfoil
This is a 1938 NACA technical report, issued by the National Advisory Committee for Aeronautics in the United States, for aircraft engineers and researchers studying icing. It examines how simulated ice on an airfoil changes its aerodynamic behaviour. The pictures are plain black-and-white laboratory photographs, wind-tunnel style test layouts, a dimensioned drawing of a tar-and-slag cloth strip, and a log-scale graph of stalling speed; a designer might take from them the rough, sculpted texture of ice shapes on metal surfaces.
