Propulsion Characteristics Obtained with Vertical Axis Propellers from LCU(A) Represented by Model 4952

Mary Cynthia Dickerson

Abstract

Propulsion tests, including investigation of bollard pull capabilities, were conducted on Model 4952 representing the Utility Landing Craft, Assault LCU(A) FY 1963. The craft is propelled by two vertical axis propellers with an installed horsepower of 680. As a result of the poor propeller performance due to air drawing in the bollard pull astern tests, it is recommended that the stern lines be altered. (Author)
