Description/Abstract

Performance tests were carried out on a semi-balanced skeg and an all-movable rudder model downstream of a propeller. The tests were carried out in a closed return wind tunnel with the wind tunnel fan stationary. The tests were not true zero speed as the model ship propeller circulated the air within the tunnel at a slow but measurable speed. This speed corresponded to a propeller advance ratio J of 0.17 and thrust loading K subscript T / J superscript 2 of 12. Performance comparisons were made for several propeller rates of revolution. Surface pressure measurements were made at 200 locations distributed over the all-movable rudder. Measurements were made for seven rudder angles between -30° and +30° at two rates of revolution of 800 and 1460 rpm.
