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
Royal Road, Springfield, Va.

PB83-162487; the price is $9.50.
