The aerodynamic design of propellers from considerations of centrifugal force is presented. A solution is obtained for the spanwise distribution of cross-sectional area required to attain constant centrifugal stress over most of the blade. By applying a constant minimum value of thickness ratio from root to tip and allowing the distribution of required area to appear in the blade plan form, propellers with good efficiency are realized at high Mach numbers by the method of this paper.
