Users Guide for Smooth-Prop: A Program for Smoothing Propeller Tip Geometry

Abstract

The traditional method of specifying propeller geometry is to define a series of airfoil sections each of which is modified by local values of the chord length, pitch, skew angle and rake. Near the tip of the propeller, where the chord length reduces rapidly to zero, a blade defined in this way often has surface irregularities which make meshing for flow solvers difficult. This report is a users manual for a program that will smooth the irregularities near the tip and save the resulting propeller geometry in the IGES format which can be read by most flow solvers.
