MarAd Releases Report

On Novel "Outside Hull"

Propulsion System

The Maritime Administration has released a technical report which further explores the feasi- bility of a novel concept for ship propulsion. The report, "Resist- ance Reduction in Merchant Ships by the New Propulsion System," was prepared for MarAd by the

University of Rhode Island.

The New Propulsion System — the name of the concept — uses a hydraulic transmission outside the ship's hull. An axial-flow pump driven directly at high speed by the ship's main en- gine (s) imparts energy to the seawater which drives the pro- peller through turbine blades at- tached inside the propeller hub.

Thrust is available from both the turbine discharge jet and the propeller.

Principal investigators of the

New Propulsion System, includ- ing the inventor, at the Univer- sity of Rhode Island, say this system configuration enables a simplified method to be used for the construction of energy-effi- cient contra-rotating propellers that are directly driven by a sin- gle shaft. This would eliminate the main reduction gear and pro- vide increased efficiency through savings in weight, space, and cost.

The development and appli- cation of the novel system has been under active research at the university for six years. It was invented by Dr. Herman E.

Sheets, who formerly headed the university's ocean engineering program.

Previous research was con- conducted under contracts with

MarAd and the Office of Naval

Research. Among other things, the researchers say, they success- fully tested a 10-hp unit in the laboratory and demonstrated the feasibility of its application to surface ships.

The latest study assessed ad- ditional benefits of the applica- tion of- the New Propulsion Sys- tem in reducing drag due to boundary layer suction about a ship's hull.

Copies of the report are avail- able from the National Technical

Information Service, 5285 Port
