Ship wave propulsion

 

(57) Abstract:

Usage: the area of shipbuilding, relates to the propulsion of vessels that use the energy of sea waves. The inventive propulsion device made in the form of tapes of an odd number of wings 1, 2, 7, which are located one above the other, and two vertical stationary racks 4 are rigidly connected by a rudder stock all 3 wings, except for the Central 7, mounted on the movable shaft 8, which is connected with the power drive. At each of two adjacent wings 1 and 2 the axis of rotation is displaced equal distances on opposite sides of the center of pressure. All the wings 1, 2, 7 in its rear part pivotally connected to the vertical rigid rods 12. 3 Il.

The invention relates to shipbuilding, namely the propulsion of vessels, using the power of the waves.

Known ship wave propulsion containing rotary wing rigidly mounted on a movable shaft, which is connected kinematic connection with a power drive, is provided with an elastic elements.

On a single wing known propulsion with an area constituting 2.5% of the area of the waterline of the vessel, when rolling a large disturbing moment that it requires to create souverinisation communication and powerful springs, having large dimensions, which complicates the placement of the actuator in the hull and creates significant hydrodynamic resistance when the external placement of the drive.

The purpose of the invention the reduction of the required power of the actuator.

This goal is achieved by the application instead of one wing several kinematically connected to each other and substantially mutually parrying disturbing moments.

In Fig. 1 shows a kinematic diagram of the thruster, side view; Fig. 2 power drive scheme of Fig. 3 section a-a in Fig. 1.

The propulsion device made in the form of tapes of an odd number of high aspect ratio wings, and peripheral wings 1, 2 freely mounted on its rudder stock 3, rigidly connecting the two vertical side posts 4, one of which is through the sleeve 5 is rigidly connected with the flange 6 of the vessel. The Central wing 7 is rigidly fixed on the rotary shaft 8, skipped through the sleeve 5 and is provided with the drum 9, connected by metal strips 10 with the compression spring 11. In Fig. 1 shows the position of the centers of pressure of the wings, equidistant from the axis of rotation, but on different sides of the adjacent wings. Wings 1, 2 and 7 in its tail h is current on each wing acts hydrodynamic force, attached to the center of pressure of the wing, the position of which when you remove the wing 6 is invariably up to a critical value of angle of attack. The moments of these forces at the adjacent peripheral wings 1, 2 have opposite direction and cancel each other out. To the actuator affects only the time from the main wing 7. In the case of coincidence of the centers of pressure of the wings 1, 2 with their axes of rotation of the moments of all peripheral wings equal to zero and the actuator also operates only from the Central point of the wing 7.

SHIP WAVE PROPULSION containing hydrodynamic profile, rigidly fixed on the shaft, the United kinematic connection with a drive of rotation, is provided with an elastic elements, characterized in that the hydrodynamic profile in the form of flat hydrodynamic lattice of an odd number of wings with rudder stock, pivotally connected at its caudal parts of the vertical rigid rods, and two vertical stationary racks rigidly to the United States between the rudder stock all of the wings, in addition to the Central fixed on connected to drive rotation of the shaft, the longitudinal axis of which is displaced forward relative to the center of pressure of the wing, at davlen equal distances.

FIELD: shipbuilding; sailing ships.

SUBSTANCE: proposed sailing ship has hull, rotary masts equipped with electric drive and rotary yards with sails, steering wheel and power sources. Wave-powered generators are used as power sources, each consisting of magnet armature connected with float and placed in vertical guide made of non-conducting material in form of tube with holes communicating it with surrounding medium and stator winding enclosed in box surrounding the guide. Ship has storage batteries to which current from wave-powered generator can be delivered. Ship can be furnished with computer to control riging and electric circuit of ship.

EFFECT: reduced consumption of fuel by engine of ship.

FIELD: shipbuilding; construction of marine sail and rotor propulsive complexes employing wind energy.

SUBSTANCE: proposed shipboard propulsive complex has rotor and sail propulsors and electric power source. Used as electric power source are electric wave generators; each generator includes magnetic armature connected with float and placed in vertical guide made from non-conducting material in form of perforated tube for communication with surrounding medium; electric generators are also provided with stators enclosed in magnetic circuit and placed in boxes embracing the guides. Masts and rotors may be telescopic in construction for stowing them inside ship. It is good practice to protect the generators with shields.

EFFECT: reduced consumption of fuel due to enhanced efficiency of employment of wave energy.

SUBSTANCE: ship has additional bottom in form of inclined surface in underwater portion of fore extremity where device for use of wave energy is mounted. Rigidly mounted in underwater portion of aft extremity is stabilizer made in form of wing profile and used for forming the differential moment. Differential moment favors increase of thrust when said inclined surface is in contact with flow of liquid in swell.

Proposed auxiliary hydroreactive device contains water guide in form of chambers arranged symmetrically relative to its longitudinal axis with water intake holes and curvilinear walls horizontal in cross section of chambers, forming nozzles narrowing in direction of flow with output holes perpendicular to longitudinal axis of water guide. Device contains one central chamber, two outer chambers and at least two inner chambers. Inlet water intake holes of outer chambers are arranged horizontally and are pointed opposite to each other. Inlet water intake holes of inner chambers are arranged at angle to longitudinal axis and they form obtuse angle with inlet water intake holes of outer chambers in vertical longitudinal section. Inlet water intake hole of central chamber is arranged vertically perpendicularly to longitudinal axis of water guide.
