A LIFTING-SURFACE PROPELLER DESIGN METHOD FOR HIGH-SPEED COMPUTERS

Abstract

A propeller design method that treats the blades as lifting surfaces has been developed and programmed on an IBM 7090 computer. The singularity distributions representing the bound circulation, shed vorticity, and blade thickness are treated as continuous sheets, making it necessary to determine the Cauchy principal value of the improper integrals expressing the induced velocities on the blades. The camber lines and pitch angles are determined from the variation of the normal component of induced velocity across the blade. This method is applicable to moderately loaded, non-optimum, wake-adapted propellers with or without skew.
