Wave powered propulsion systems for submarines and quasi-dipped watercrafts

Abstract

The wave powered (WP) propulsion systems developed in great amount for boats are not in use because of small effectiveness caused by rocking process reducing propellor stroke relatively water. Submarines and special quasi-dipped watercrafts deprived of this disadvantage. Their bodies keeps stable the propellors mounted on conning towers or special props owing to the body's great mass. This factor multiplies the WP propellor effectiveness meeting Navy and Merchant fleet requirements. The invention includes designs of: spare WP propulsion plant embedded into submarine diving rudders or folded into pockets of the submarine sail, quasi-dipped watercraft carrying multiple foil WP propulsion system, quasi-dipped tug towing submerged tank, self optimized foil propellor. Experiences with submarine models equipped by the WP propellers have shown excellent results. Expected velocities for submarine 4-7 knots, for the quasi-dipped watercraft 5-15 knots. The folded spare WP propulsion plant does not interrupt submarine functioning.

Description

[0001] The invention has no analogues.STATEMENT REGARDING FEDERALLY SPONSORED R & D[0002] The author created the invention by himself with own means in duty free time.REFERENCE TO A MICROFICHE APPENDIX[0003] Not Applicable.[0004] Endeavor: Most efforts developing or improving existing submarine propulsion systems are directed basically on two kinds of them: nuclear and diesel systems. In both cases a submarine needs some type of fuel with nuclear or chemical ingredients. Usage the second one limits a range of a submarine independent operating distance. Both types of the propulsion systems never become absolutely reliable and noiseless.[0005] Here we suggest the new kind submarine propulsion system, which was not considered before. It is a WP propulsion system. This asserts clear that a submarine needs contact with waving water surface or with subsurface layer, i.e. it does not certainly need to emerge fully. Rather it emerges only by its conning tower, a part of it or without coming...

AI Technical Summary

Benefits of technology

[0016] So the hydrofoil obtains the maximum possible hydraulic pressure from waving water masses and the submarine has minimum water resistance and zero wind load. These are great advantages and it is why the submarine WP propulsion system is a few times more effective than the analogous system mounted on the surface ships.

Problems solved by technology

Many of these are failed because the water surface ships do not provide proper conditions for a wave-powered (WP-) propellor like a hydrofoil attached to a board under water pivotally elastically with eccentricity of a pivot axis and a foil hydrodynamic head center.
