Abstract

Propeller design charts such as MAU, Wageningen B, etc. are usually used for propeller design in the present. But the shape of actual propeller is not necessarily similar to that of original propeller of the design chart. The influence of boss ratio and blade thickness on propeller open characteristics can be calculated by Taniguchi's method that is generally used in practical propeller design. However, Taniguchi's method can not be applied to calculate the influence of blade contour and thickness distribution. In this paper the influence of blade contour and thickness distribution of MAU type propeller on open characteristics is examined experimentally, and practical method which can calculate the influence of blade contour and thickness distribution on open characteristics is proposed. Blade element theory which is simpler than lifting line theory and lifting surface theory is applied in present method. In comparison with experimental values, it is demonstrated that present method will become an useful means in practical propeller design.
