Selection of a Propulsor for a Submersible System

Abstract

sign and development of ocean-going hydrofoil ships. With the exception of having demonstrated full design capability in rough water, the craft has met or exceeded all of her design goals, including a verification of the concept of the turbinepowered, fully submerged foil ship being routinely operated by the white hat Navy. Sporadic leakage of salt water into the transmission oil sumps has been the principal reason for limited reliability to date. This and other problems evaluated during the test program can be corrected, as presently envisioned, without major alteration of the craft. In contrast, much operational experience and test data have been obtained that commend many of the more gross aspects of the craft design. Seakeeping characteristics while hullborne, takeoff performance foilborne comfort, and safety have been found to be most satisfactory. The high vehicular efficiency of the full-scale craft was accurately predicted by model work done prior to construction of the ship.
