THE INFLUENCE OF BLADE CONTOUR AND BLADE THICKNESS DISTRIBUTION ON PROPELLER OPEN WATER CHARACTERISTICS

Shosaburo Yamasaki, Masafumi Ito

Abstract

The influence of blade contour and thickness distribution of MAU type propeller on open water characteristics is examined experimentally, and a practical method which can calculate the influence of blade contour and thickness distribution on open water characteristics is proposed. Blade element theory which is simpler than lifting line theory and lifting surface theory is applied in the present method. In comparison with experimental values, it is demonstrated that the present method will become a useful means in practical propeller design. Order from NSFI as No. 22158.
