podded propulsors; dynamic azimuthing; propeller thrust and torque
This paper presents some of the results obtained during the recent opens experiments performed with a model podded propulsor. The model propulsor is instrumented to measure thrust and torque of the propeller, three orthogonal forces and moments on the unit, rotational speed of the propeller, azimuthing angle and azimuthing rate. The model was first tested at various sets of azimuthing angles with varying advance coefficients. These tests were followed by the tests in which the azimuthing angle was varied dynamically. The results for propeller thrust (KT) and torque (KQ) as well as unit thrust (KT_unit) are given for the dynamic azimuthing cases. Comparisons of the same parameters between the tests with static and dynamic azimuthing angles are also presented.
