Abstract
Mathematical models of propeller thrust and torque are traditionally based
on steady state thrust and torque characteristics obtained in model basin or cavitation
tunnel tests. Experimental results showed that these quasi steady state models do
not accurately describe the transient phenomena in a thruster. A recently published
dynamic model was based on the experimental observations. Describing zero advance
speed conditions accurately, this model, however, does not work for a vessel at non-
zero relative water speed. This paper derives a large signal dynamic model of propeller
that includes the eects of transients in the
ow over a wide range of operation.
The results are essential for accurate thrust control in dynamic positioning and in
underwater robotics.
