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.

What I claim as my invention is:  
     
         1 . Submarine wave powered (WP) propulsion system consisting of two elastically deflected foils attached to extremities of a submarine sail along a central line with inclining arms able to rise or to lower said foils parallel themselves and providing their usage wave powered propellors from various depths closest to water surface.  
     
     
         2 . Spare submarine WP propulsion plant embedded to and expanding from diving rudders to convert them to the WP propellers functioning in the water subsurface layer when waving; after the usage the plant is retracted back into the rudders to continue standard mode of operation.  
     
     
         3 . Independent spare submarine WP propulsion plant with WP-propellors folding into submarine sail side pockets in standard submarine mode operation and opening from them in order to catch wave energy propelling the submarine; the rear WP-propellor may have foil extension increasing quantity of caught wave energy boosting the submarine.  
     
     
         4 . Quasi-dipped watercraft providing the best conditions for installation and operation multi foil WP propulsion system able to consume maximum quantity of the wave energy; said watercraft moves at a maximum speed because it also has minimum area of its parts jutted out of the water and experiencing wind head.  
     
     
         5 . Wave powered (WP) tug working in conjunction with towed submarine tank (barge), which provides great inertia needed to support constant vertical disposition of the WP-propellors creating thrust via own elastic inclination deflecting backward water masses moving up and down by wave motion.  
     
     
         6 . Wave powered (WP-) propellor with self controlled optimal inclination respecting to water mass movement direction; the WP-propellor consists of two foils (propelling and auxiliary) installed on a motionless shaft; the auxiliary foil works as weather vane and tilts the propelling balanced foil to half own inclination via lever mechanism.
