US Patent:
4622016, Nov 11, 1986
Filed:
Nov 20, 1980
Appl. No.:
6/208754
Inventors:
Donald W. Hankley - Virginia Beach VA
Assignee:
The United States of America as represented by the Secretary of the Navy - Washington DC
International Classification:
B63H 516
US Classification:
440 70
Abstract:
A full or partial tunnel wedge is positioned in the propeller shaft tunnel ft of the propeller on a waterborne craft. The size and angle of the wedge is determined by the characteristics of the particular craft. The wedge converges water flow and increases water pressure aft of the propeller. The higher water pressure increases the propeller thrust and reduces the hull drag of the propeller shaft tunnel thus reducing the shaft horsepower required to maintain a given speed.
