 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.

The device relates to the field of marine engineering and is used to convert the energy of ocean currents (waves, tides) in force, driving the ship. Known tidal wave hydro power plant (A.S. No. 1211441, IPC F03B 13/12, bull. No. 6, 1986), comprising a fixed pontoon, buried under the sea level and attached anchors to the bottom, movable pontoon and the power Converter, the hydroelectric power plant is equipped with two flexible containers filled with the working environment, and a flexible conduit connecting the elastic capacity installed in the power Converter, thus moving the pontoon is made in the form of a platform attached to surface floats through rigid vertical ties, and elastic capacity are located between the fixed pontoon and seabed vertically one above the other, and the platform, interacting with containers located between them. Fixed pontoon installed at sea level at the time of low tide. A device for converting the energy of the air flow into force, driving the ship, including the hull, sail, hollow (two) circular cylinders-rotors, rotating around a vertical axis, which is attached to the deck (Aplattner "Three-masted motorneurones brig, Boucau" from the book Nahapiet "Course on aerodynamics, part first, of the publishers of the heavy industry of the USSR, M, L., 1938, s-153). The basis of this device is based on a pattern: when the flow around a circular cylinder flow circulation (replacing the circulation of rotor rotation around the vertical axis) produces a lifting force F which is directed along the longitudinal axis of the vessel (to nose) at a 90° angle to the direction of the approach flow V on the port side of the vessel during rotation of the rotor in a clockwise direction. The main disadvantage of this device is that it uses the energy of the air flow, density (ρd=1,228 kg/m3) which is considerably lower than the density (ρwater=1000,0 kg/m3) water. It is known that the lifting force is F=ρV, where ρ is the density of the fluid that flows around the rotor circulation G when the approach speed V From the formula it is seen that the lifting force is directly proportional to the density streamlined fluid. Thus, when the flow around the rotor water force F will be much greater than F around the rotor air. The proposed device more efficiently uses the flow, as it uses currents (ρwater>ρd) to convert their energy into force, driving the ship. A device for converting the energy of sea currents in force, driving the ship, including the hull, several hollow circular cylinders-rotors installed with the possibility of rotation around-ear, closed the g vertical axis, the drive rotor, a device for switching the direction of rotation of the rotor, the electrical power source is a battery, the electric rotating ship propeller, wherein the hull has a number of transverse cross-cutting channels that have the rotors so that the longitudinal axis of the rotor coincides with the longitudinal axis of the vessel, and the transverse axis of the rotor is offset from the transverse axis through channels by an amount equal to half the diameter of the rotor, and the window between the side wall of the through-chamber and the rotor from the side of the nose is smaller than the window at the stern side of the vessel. Cross through the channel in cross section has a rectangular shape whose height is greater than its width. A device for converting the energy of sea currents in force, driving the ship, illustrated by drawings: figure 1 shows the device; figure 2 - a view A - A figure 1. In the hull of the vessel 1 made several cross (rectangular) through channels 2, which has a hollow circular cylinders-rotors 3 with the possibility of rotation around the vertical axis 4. When the approach for V from the left side of the ship, the rotors revolve in the direction 5. The rotation of the rotors is made from the actuator 6. As part of the device has a device 7 for changing the direction of rotation of the rotor counterclockwise in that case the e, when the approach flow perfect with the right ship. The rotors are mounted so that their longitudinal axis 8 coincide with the longitudinal axis of the vessel 9, and the transverse axis 10 is offset from the transverse axis 11 through channels by an amount equal to half the diameter of the rotor, and the window 12 between the side wall of the through-chamber and the rotor from the side of the nose 13 is smaller than the window 14 from the stern of the vessel 15. The gap between the bases of the rotors and the upper and lower walls of the through channels is minimal. The structure of the device includes a source of electric current - the battery 16, the actuator 17 of rotation of the propeller 18 of the vessel. This equipment is necessary for the rotation of the rotors and ship maneuvering in the absence of ocean currents. Legend: V - direction approach speed sea currents; F - direction of the lifting force, which moves the ship forward. The device operates as follows. A ship at sea is placed so that the direction of sea currents V had on Board a ship. If for V from the left side, the direction of rotation of the rotor 3 of the electric actuator 6 is clockwise 5, if from the right, the device 7 changes the direction of rotation in the counterclockwise direction. The rotors 3 are streamed sea for circulation, the circulation flow is formed by the rotation of the rotor 3 with a little speed. RAS is the definition of pressure flow on the lateral surface of the rotor 3 is uneven. In the area of the window 12, the negative pressure is achieved by rotation of the rotor coincides with the direction of current flow, and due to the high velocities of flow in the window 12, the cross-sectional area which is smaller than the cross-sectional area of the window 14. In the area of the window 14 has positive pressure. As a result of this pressure distribution is generated lifting force F, the direction of which coincides with the direction of the longitudinal axis 9 of the vessel. This force F pushes the ship forward. When placing multiple rotor axis 9 of the forces F are added. In the absence of sea currents, the ship moves (maneuvers) using a propeller 18, the rotation of which is produced from the drive 17 and a power source 16, which is also used to rotate the rotor 3. The introduction of the device will allow you to use the energy of sea currents for movement of the vessel. The simplicity of the device and the availability of technical inspection of its elements will allow it to be operated with a minimum expenditure of electrical energy. 1.
