THREE DIMENSIONAL APPROACH TO THE GUST PROBLEM FOR A SCREW PROPELLER

Abstract

The unsteady lifting surface approach is utilized for the marine propeller case and the correspond ing surface integral equation is solved for the Weissinger mathematical model. The applicability of the Weissinger method to the nonstationary flow case is studied. The kernel function is expressed in closed forms after some mathematical simplification. From numerical calculations of propeller loading which are restricted to a four bladed propeller of sector type blade form with different blade-area ratios and various pitch diameter ratios, conclusions are drawn as to three-dimensional effects as well as to the de pendence of propeller loading on the important parameters, as the blade-area and pitch-diameter ratios.
