description abstract	Full-scale tests have been made in the Langley 16-foot high-speed tunnel t o determine the aerodynamic characteristics of the NACA 10-(3) (08)-03R propeller. The tests on this propeller were conducted as part of a program to determine the effects of shank design on propeller aerodynamic characteristics. The tests were made on a 2000-horsepower dynamometer over a range of advance ratio from 0.45 to 3.6. The blade-angle range, measured at the 0.75-radius station, extended from 20° to 50°. A maximum efficiency of 91.5 percent was attained at 1600 revolutions per minute at a blade angle of 30°. Peak efficiency at a blade angle of 45° was decreased 32 percent by an increase in helical-tip Mach number from 0.80 to 1.2.
