ABSTRACT
The B-series propellers were designed and tested at the Netherlands Ship Model Basin in Wageningen.
The open-water characteristics of 120 propeller models of the B-series were tested at N .s.M
.B.and analyzed with .multiple polynomial regression analysis [1] . The derived polynomials express
the thrust and torque coefficients in terms of the number of blades, the blade area ratio, the
pitch-diameter ratio and the advance coefficient. The Rey nolds number effect and the effect of
variation of blade thickness on the B
series propeller characteristics have also been evaluated at N .S.M.B . In this report the
polynomials derived in [1] are used to plot the open water propel ler characteristics for Reynolds
number 2.ox106 and for the ranges of number
of blades, blade area ratio and pitch-diameter ratio recommended by N .S.M .B. The extent of
applicability of the regression polynomials is also discussed.
