Book excerpt: The AO-177, first of a new class of Naval Auxiliary Oilers, experienced high levels of inboard airborne noise and initial-stage erosion damage on its skewed, seven-bladed propeller during builder's trails. This report describes the problems, corrective design modifications considered, and procedures and rationale used to develop a successful corrective design modification consisting of a fin to improve the flow into the propeller. To evaluate the problem, extensive model experiments were conducted, including flow visualization, wake survey, powering experiments, and a crucial series of cavitation experiments including propeller-induced hull pressure measurements in a large water tunnel. Experiments with two fin designs showed the superiority of a flow-accelerating configuration. Other experiments showed some benefits of altering the propeller blade shape. Propeller analyses were undertaken to provide design alternatives for retrofitting the ship with a new propeller. A full-scale trail with the final fin design provided evidence or reduction of the highest levels of airborne noise, reduction in the initial-stage erosion damage, and minimal effect on ship speed. The result is that the AO-177 has been accepted by the fleet for normal service. (Author).

This book was released on 1981 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Resistance and propulsion experiments were conducted with Model 5326-1 to aid in the resolution of the propeller cavitation and airborne noise problem experienced by the Auxiliary Oiler AO 177 and to validate possible remedies. The experimental program involved the evaluation of two tunnel-fin configurations and one accelerating-fin configuration fitted to the stern of the model. The results of the resistance and propulsion experiments show that the addition of the fins did not significantly change the propulsion performance. (Author).
