In main or complementary sail propulsion five systems for vessels and tugboats thereof.
The propulsion of ships is not sufficiently exploited at present. There are some with sail systems but they are expensive and not suitable for most of them. The present invention uses sails, even automatically produce propulsion in a simple and economical way, and is valid even for tugboats.
Provide a simple and inexpensive, practical sail propulsion system for vessels and tugboats, which can be automatic, easy and quick to install in today's ships and which, by reducing fuel consumption and the duration of the trips, provides a great saving, It is very ecological and safe, especially for gas ships, CO2 emissions are reduced. Being the only transport system totally ecological.
Use large surface and low draft tugs, which can withstand large sails.
Use catamarans of large lengths or in series, articulated, hinged or with spherical plain bearings, that allow the great oscillations generated by the big waves or the rough sea.
The system and method of sail propulsion for sailing vessels and tugboats of the invention consists in the use in vessels and tugboats of one or more rows of sails fastened to their upper vertices or edges by the ends of a few masts and cables or ropes placed between the upper ends of masts or the ends of the radial arms thereof, some masts in the bow and others in the stern. Said sails being fastened by their lower vertices or edges to some rings fixed to the deck, to ropes or cables whose ends are fixed to the deck, to small stakes, to the lower part of the main masts, to the ends of some radial arms fixed in the lower part of the masts, or to pulleys in which they are rolled with motor.
The masts, with or without radial arms, can be rotating and can be placed with a backward inclination between 10° and 30° with respect to the vertical. Avoiding the wind incident on the sails to be thrown towards the outside, nor pressed the ship against the water, with the consequent loss of performance.
Rows of sails aligned from bow to stern, carry a mast in the sails of the ends. In the intermediate sails, cables or ropes make as upper ends of the sails.
You can add a propulsion system using paragliding kites.
The sails can be applied on the sides and/or in the upper area of the vessels or tugboats. When the sails are applied laterally, extensible or rotating arms are added and the masts are used for fastening in the upper area. The extensible arms may be flexible or be formed of several interconnected or joined together with straps. The ends of the arms placed on the sides are fastened with magnets, open clamps or flexible hooks.
The sails can be mostly triangular, rectangular and trapezoidal, fixed, of automatic extension, rotating and controlled manually or by microprocessor. The sails may have reinforced edges, vertices or corners, and their edges may have a fixed or fastened tubular shape, which can be secured by surrounding a cable or support cable.
The triangular sails can be fastened from their upper vertex from the cables between the ends of the masts, with a vertical cable that serves as support, as does the mast, or without the cable, in this case the two lower vertices are attached to two cables and with its displacement, the proper inclination is given to the sails to take advantage of the lateral wind efficiently or to navigate bowline or upwind.
The triangular sails may have in their central zone a cylindrical or truncated cone shape sleeve to introduce and facilitate securing to the masts.
The rectangular or trapezoid sails are placed and secured to four ropes or cables arranged parallel to the longitudinal axis of the vessel or tugboat and are supported between two pairs of masts or two masts with four radial arms in trapezoidal, each pair has a mast in the bow and another in the stern. Those of two pairs of masts, can have their upper ends inclined or can be tilted toward the outside. The most useful is to sail bowline or crosswind, which has the longest use time.
The system is used as the only power or as a supplement to the propulsion made by other means, engines, turbines, etc. In all cases the energy saving is very important.
The weight can be reduced by using masts made of aluminum alloys, fiberglass or carbon fiber which are also not affected by corrosion. Canvas sails, plastic like Kevlar, a registered trademark of E. I. du Pont de Nemours and Company, Wilmington, Del., polyester, etc., are generally flexible but can be semi-rigid or rigid.
A microprocessor, or the main processor, can drive servo motors, rams, actuators or controllers of the sails and the rudder in function of the signals of course of the ship, the route to follow, of GPS, direction and intensity of the wind and the swell, control knobs, manual actuation of the sails, total or partial retraction of the sail, etc.
The sails or their cables can be lowered using motors and pulleys. Their surface can also be reduced by winding them on the masts or radial arms. Another way to reduce its surface is by lowering its top vertex by attaching it to a cable in closed circuit and driving it with an electric motor and pulleys. A similar system is used to collect the sails, in which case the sail are extended or withdrawn by moving between three or four cables by means of rings at their vertices, motors and cables in closed circuit move the sails, retracting or extending them with the angle as a function of the wind. The corners of the sails must be joined together with laces so that once extended they maintain identical distances between them.
The masts can be telescopic and can be tilted and even fully collapsed in their lower zone, using hydraulic rams or motors and gear reducers.
When sails make vision difficult, the control tower can be located in the front area or a video camera can be used to view without difficulty.
The boat can be catamaran type, using four masts located in four corners or their proximities and with rectangular or trapezoid sails that can have the greater base in the upper zone using masts inclined towards the outside.
You can add a propulsion system of paragliding kite that pull the boat and are supported by cables or ropes directed with the resultant of the applied forces by the wind, the paraglide of the upper end carries a chamber or bag of helium and the set is wound on a roller-pulley driven by an electric motor. Paragliding kites are replaced by a parachute with a cable through its axis of symmetry, which also holds the ends of the parachute cords. They are used with the aft or aft side winds. In the upper end also 25 carries a helium chamber or bag.
The sails can also be extended automatically with the action of the wind, or manually operated with a remote control, and taking into account the direction of the wind and the waves, this for small boats.
The masts can be telescopic and can be tilted and even fully collapsed in their lower zone, using hydraulic rams or motors and gear reducers.
The catamarans and tugboats hulls as they are of great dimensions, low height and not excessively resistant can be formed by several modules or boats, articulated, hinged or with ball and socket joint, allowing great vertical and some muffled sides oscillations.
The control tower can be located in the front area.
