Book excerpt: Aerodynamic tests of a 12.208-foot-diameter two-blade hollow steel propeller before and after alteration for thermal de-icing have been made in the Langley 16-foot high-speed tunnel to determine the effect of the alterations on propeller efficiency. The propeller, which had Clark Y blade sections, was tested on a 2000-horsepower dynamometer at blade angles ranging from about 25 degrees to 60 degrees at the 42-inch radius and at airspeeds varying from 100 to 425 miles per hour.
