 Sectional elastically bendable ship, its rocking-driven thrust system and method of cargo delivery by sea exploiting energy of waves / 2356783
Set of inventions relates to sea transport facilities. The proposed sectional elastically bendable ship represents three sections elastically pivoted together so that the central cargo section "hangs" on extreme very light inertialess sections to press them in water by the springs so, that they float horizontally. With sea disturbed, the balance it is broken to the extreme sections to roll. Relative movements of heavy central section and extreme inertialess sections rolled by the waves are transformed by mechanisms of oscillating fin thrust system into moves of thrust wings of the extreme sections that makes the ship to move. The method of cargo delivery by sea is based on formation of floating train-like structure according to the design of sectional elastically bendable ship wherein the cargo can be represented by both floating objects, including towed vessels, and not floating objects, including the tanks filled by liquid products.
 Ship driven by hull pitching energy / 2365520
Invention relates to ship building, particularly to ships exploiting pitching energy to set the ship in motion and/or to supply its loads. Proposed ship comprises a hull with its contents isolated and built in the platform elastically mounted inside the hull. The hull can be forced by waves to pitch relative to the platform in midplane within the limits allowed by springs. Ship propulsors represent propulsion elastically vibrating wings extended from ship bow and stern with the help of rigid load bearing beams.
 Pitch-driven ship and pitch drive propulsor / 2392177
Pitch-driven ship is a ship exploiting pitch energy to drive it at sufficient water heaving. Pitch-driven propulsor comprises elasto-vibrating wing that makes a propulsion generator. Said wing oscillates when ship hull pitches and is fitted on stream-lined posts-holders arranged below ship hull at preset depth. Water heaving at said depth can be considered zero, not decreasing the difference in vertical velocities of the wing and water (wing propulsion varies with square difference). To reach maximum wing propulsion, proposed propulsor is arranged nearby ship edge. Effect of separate wing increases if propulsor is mounted on every edge of the ship. Note that, in this case, propulsion and alternating acceleration are smoothed. Pitch-driven propulsor design is distinguished for by the number of posts-holders, i.e. one or two, and propulsor can be made lifting, rotary or fixed. Also there can be retractable wing extensions and wings can be made folding. Note that wing halves can vibrate independently. Proposed ship is with furnished with two pitch-driven propulsors. Flat horizontal flaps can be arranged on ship edges, nearby deadline, and screw propellers can be used in low heaving conditions.
 Lifeboat with propulsion device and lifeboat indirect application / 2397104
Invention relates to shipbuilding, particularly to rescue floating appliances. Proposed lifeboat comprises propulsion device incorporating electric current generator. In compliance with one version, stator is secured in lifeboat, while rotor can oscillate about its axis driven by waves acting on lifeboat. In compliance with another version, rotor is arranged in lifeboat while stator, suspended on rotor shaft, can oscillate about its axis driven by waves acting on lifeboat. Rotor in first version and stator in second version are statically unbalanced because of eccentric shift of the center of masses from axis of rotation. Generators may be arranged in lifeboat in lines along its axis with their axes either parallel or perpendicular to lifeboat axis. Proposed lifeboat can be used for electric power generation aboard the ship.

Invention relates to ship building and pertains to devices to convert sea current forces into ship propulsion forces. Proposed device comprises ship hull, several hollow annular cylinders that make rotors arranged to rotate about vertical axes, rotor electric drive, appliance to reverse rotor rotation, power source, a storage battery, and sip propeller screw electric drive. Ship hull is provided with several crosswise through channels to accommodate rotors arranged so that their lengthwise axes are aligned with ship lengthwise axis, while their crosswise axes are shifted from through channel crosswise axes by magnitude equal to half the rotor diametre. Opening between through chamber sidewall and rotor on bow side is smaller than that on ship stern side. Crosswise through channel cross section may have rectangular shape with its height exceeding its width.

FIELD: transport, ship building. SUBSTANCE: proposed wave propulsion unit consists of water propeller fitted on the crankshaft mounted on brackets attached between the catamaran bodies. The positive buoyancy floats make active elements driving the crankshaft. The said floats move vertically when waves pass between the catamaran bodies. The power of waves is transmitted, via the floats, connecting rod gear and crankshaft, to the water propeller. EFFECT: simpler design. 1 dwg
The invention relates to shipbuilding, namely the propulsion that uses the energy of sea waves. The average condition of the seas and oceans is a condition in which anxiety is 3-4 points [1]. It remains to solve a technical problem: to create a device that will extract and convert the energy of excitement. One of the devices [2] contains the floating module, the casing of which is provided with a wave propulsion device for forming the angle of attack and horizontal ballast compartments. The complexity of this design is aggravated by the fact that the device stands for the dimensions of Vologda and thereby affects its seaworthiness. Some devices that use wave energy [3], do not extend beyond the dimensions of the ship, but a small amount of potato and a small surface of the submerged part of a fore end of the ship, interacting with the energy of the wave, not allow to considerably increase the speed of the vessel in waves. The closest to our invention and adopted for the prototype is anodically machine [4], which uses the energy of sea waves to rotation of the propeller and vessel motions in waves. As working elements of the machine are used wave wing propulsion, which in the interaction of the incident wave create traction force. The disadvantages of this device the trail is t to include the complexity of the design and that wave wing propulsion for interaction with the wave must be placed over the size of the ship. In our invention, the technical solution of the location problem vandigital installation is carried out in such a way that all its components are located between the hulls. The device ship vandigital posted on the catamaran 1 (see drawing) consists of floats 2, having positive buoyancy and performing vertical vibrations during the passage of waves between the hulls. The floats are connected through a crank mechanism 7 to the crankshaft 3, lying on the supporting bearings 4, rigidly connected by means of brackets 5 hulls. On the aft crankshaft mounted propeller 6. The device operates as follows. With the passage of the wave 8 (see drawing) between the hulls 1 floats 2, having a positive buoyancy, are set in motion. The movement of floats is in the vertical plane. In the vicinity of the top of the wave, the float reaches the top of its provisions, and in the area of the sole - wave bottom. Between the top and bottom of the wave floats occupy an intermediate position. Thus, when vibrations in a vertical plane on a rampage, floats, connected with a crank mechanism , rotate the crankshaft 3, lying on the supporting bearings 4, rigidly connected by means of brackets 5 hulls 1. The crankshaft 3 transmits the rotation of the propeller screw 6 mounted on its stern. Sources of information 1. Kazan C.V., Sterowanie vessels. M.: Transport, 1963 2.
