CALCULATION OF OPTIMUM EFFICIENCY FOR A SERIES OF LARGE-HUB PROPELLERS FOR APPLICATION TO TANDEM PROPULSION OF A SUBMERGED BODY OF REVOLUTION,

Abstract

Calculations were performed to determine the efficiency of integral bow and stern propellers for a body of revolution. Such a propulsion system leads to propellers with large hubs relative to the tip diameter and a large number of blades. The calculations were carried out for a propeller with 13 blades with various tip diameters, blade areas, and rpm's. The series results are presented, analyzed, and applied to computing the propulsion performance of a hypothetical 250-foot tandem propeller submarine.
