Estimating the term…
To reduce the total ship resistance and to improve a propeller efficiency and cavitation performance due to the reduced thrust loading on the propeller for ships or vessels having a sonar dome or an equivalently shaped designs located below the baseline of the hull, a teardrop-shaped bulbous bow is attached to the ship stem bow between the forward perpendicular of the bow and 12.7 ft forward of the forward perpendicular of the vessel, inclusive, and between the ship design waterline and the baseline. The bulbous bow is separate and discrete, and spaced from the sonar dome and has a shaped of a teardrop. The teardrop shaped bulbous bow is mounted to the ship stem bow with the round end portion pointing in the forward direction and the pointed end portion pointing in the aft direction.
A bulbous bow for use with a surface ship having a bow mounted sonar dome located at a ship stem bow, below a ship baseline and extending forward of a ship forward perpendicular, said bulbous bow and sonar dome located in a vertical alignment and having a common centerline, to improve efficiency thereof, comprising:
In a surface ship having a sonar dome located substantially at a forward section of the ship and extending forward of a ship forward perpendicular and below a ship baseline, an improvement comprising:
A surface vessel of improved performance capability comprising:
A method of reducing hydrodynamic resistance and thus improving propeller efficiency and cavitation performance of a vessel having an appendage located below a vessel baseline and extending forward of a vessel forward perpendicular, comprising the step of:
