 INTERIOR IN A HELICAL FORM

DESCRIPTION

OBJECT OF THE INVENTION

 The invention relates to a propulsion system of ships by means of tubes, which in their interior have helical machineries of different passage and that drive the water through said tubes without turbulence and at high speed, due to a greater compression of the water in the first part, what drives the ships that use it in a similar way to how jet engines work

The low efficiency of the propellers is known. The efficiency of a propeller of a boat is in the environment of 10% of the applied power, this means that only 10% of the energy contributed by the engine to the propeller is translated into thrust of the ship, while the 90 The remaining% is applied to move the surrounding water.

FIELD OF THE INVENTION This invention has its application within the naval industry, especially with regard to the motorization of boats.

BACKGROUND OF THE INVENTION. The applicant is currently unaware of the existence of an invention that is equipped with the features described in this report.

DESCRIPTION OF THE INVENTION The invention relates to a propulsion system of ships by means of tubes, which in their interior have separate helical machining of different pitch and which drive water through said tubes without turbulence and at high speed, due to to a greater compression of the water in the first part, what drives to the ships that use it of similar form to how the engines of reaction of the airplanes work. It is a mechanism that aims to replace the propellers of ships and could also be applied to water pumps and is more efficient.

The propeller is a very inefficient advancement device, it is calculated that of the energy contributed by the engine, only 10% is transformed into a thrust force. Furthermore, all this is achieved only at a constant speed, determined by the shape of the propeller. If that revolution regime is exceeded, the propeller loses even more efficiency. The mechanism is as follows: The propeller when it cuts the water, generates two forces, one perpendicular to the trajectory (which is lost and used to remove the water) and another in the direction of the trajectory that contributes to the advance.

Ideal angle: If the angle is greater than 45 ^e , the perpendicular force is very strong and the propeller does not rotate. If the angle is less than 45 ^e the propeller is revolutionized a lot, but it does not advance. The ideal angle is 45 ^e , because it is the one that makes the forward force is maximum.

That is why there is no single propeller design, but depending on the speed for which the boat is designed, a propeller is fitted that does well.

But if the propeller is revolutionized beyond those parameters, efficiency decreases and fuel consumption goes up.

Note that just by inventing a device that went from 10% efficiency to 20%, the power and size of the propulsion engines could be reduced by 50%.

As for the invention itself, it consists of two tubes, with their own internal machining, which are welded at one end to a gear wheel. These cogwheels, facing each other, act as a planetary of a differential mechanism

The differential mechanism receives the torque from the motor and distributes it by means of a crown and satellites to the two tubes and in this way the tubes are allowed to rotate at different revolutions. The mechanism thus designed ejects the water backwards according to the law of "action-reaction"(Newton's third law) .The mass of water expelled back multiplying by its speed is equal to the mass of the ship by its speed. its design, this mechanism has no pressure loss, beyond the inevitable friction forces, between the pieces between them, and the water molecules that exit through the nozzle, and collide with the water molecules of the sea, which are that add the moments of inertia of the parts in rotation, both tubes have an "inner helix." In tube 1, the propeller turns around the inside of the cylinder, in tube 2 the spiral of "n" turns ( being "n" a convenient number, in the prototype shown n = 5) along the length of the cylinder, in this way the water arrives "pressurized" from "tube 2" to "tube 1" thereby achieving Water back with more force and pressure.

The fact that the two tubes are connected by means of a differential mechanism guarantees that the tubes can rotate at different revolutions.

In this mechanism, as soon as one of the cylinders has a torque lower than the other, the differential will accelerate it, equaling the torque at a higher angular velocity.

In this mechanism works the principle of FEEDBACK that consists of the tubes going to act each other and to accelerate each other and this device has at least two different uses:

A - Boat propulsion mechanism.

 B - Submersible propulsion mechanism.

The submarines are detected at long distance, by the noise emitted by their propellers. This device DOES NOT HAVE EXTERNAL MOVING PARTS so the submarine can navigate in stealth.

Therefore, a propulsion mechanism for watercraft, which replaces the propellers, is claimed as its own and original. This mechanism of flame "system of propulsion of ships by means of tubes, that in their interior take separate helical machining of different step and that drive the water through these tubes without turbulence and at high speed.

This mechanism consists of three main elements that are two hollow tubes, with a propeller machined inside, and with a gear on each end and a "mechanical differential".

The hollow tubes have a special machining in the form of a helix. The internal machining in helical form of the tubes must have a relationship between them. Characterized because each internal helix machining must have a different step, (the step being the distance between two ridges).

Typically, one of the tubes will have a machining in one step and the other tube machined in "n" steps.

The purpose of the internally machined tube in helical form in "n" steps is to pressurize the water before it reaches the other tube. The purpose of the tube mechanized inside helically in one step, is to expel the water to the outside at high speed.

The above-mentioned hollow tubes must have a cogwheel that will act as the planetary of the "mechanical differential" rigidly and permanently attached to one of its ends.

These tubes must connect to each other, by means of a "mechanical differential", placing them in such a way that they can be coupled to the "mechanical differential". The three elements mentioned above, and connected as indicated, work as follows. The torque of the boat engine reaches the differential, this differential distributes the torque to each of the tubes by means of a "mechanical differential". Since each of the tubes has a helix inside with a different pitch, the differential will spin the tubes at different speeds. In this way, the sea water enters the mechanized pipe first with "n" steps where the water is pressurized on the other pipe, which expels the water to the outside with great speed. This advance system of watercraft is based on the physical law of the "linear impeller" which says for this case it says: "the mass of water ejected multiplied by its speed is equal to the mass of the boat by its speed"

An improvement is that this system has very few friction forces and therefore is more efficient than a propeller whose efficiency is estimated at 10%, while the other is that it allows the ship a very wide range of speeds, as the device without more than increasing the angular velocity of the device.

Therefore I want to claim as own and original the tube with specific machining.

It is a hollow tube with helical inner machining, as detailed in figures of this report.

This tube can also be used to move electric turbines in a waterfall, like a simple water pump. Traditional turbines transform Energy

Water potential, in kinetics by passing water through a turbine composed of a crown and an impeller. This system produces a lot of energy loss due to friction and water shocks on the walls of the turbine and the impeller. In some designs, the water when leaving still has a lot of speed then that energy is also lost.

In the market there are different types of water pump, but, there is no pump, inside which there is a tube with the shape presented in this memory.

The improvement (in both cases) consists of "energy efficiency". In the case of being used in a "waterfall" to move an electric turbine, the water from the reservoir goes directly through the tube making it turn. The water does not suffer energy losses due to change of flow direction or turbulence, or collisions with the walls of the turbine or with the impeller.

In the case of a water pump, the same thing happens. DESCRIPTION OF THE DRAWINGS.

System of propulsion of ships by means of tubes, that in their interior take separate helical mechanizations of different step and that impel the water through said tubes without turbulence and at great speed, due to a greater compression of the water in the first part.

The device proposed by the invention incorporates a plurality of novel features in relation to other elements used within the sector.

More specifically, the device is made up of the following elements:

.- Tube 1 (10) of water inlet, free at its water inlet ends and with a gear wheel (1 1)) at its other end, machined inside helically (14) of smaller step.

Said helical machining (14) has a step n times smaller than the internal machining (15), ie "wound n" times, so that pressurizes the water inside the tube (1) before it passes to the tube (2)

.- Water outlet pipe (12), free at its water inlet ends and with a gear wheel (13) at its other end, machined internally helically (15) to expel water of greater pitch than machining interior (14), in this case "rolled" only once, so that the water that comes from the tube 1 (1 1) is expelled to the outside by the free end of the tube 2 (12) at high speed, which confers the displacement of the ship.

Both tubes, located one after the other, are connected to each other in continuation and by means of their gear wheels (11) and (13) to the third element, a mechanical differential, constituted by the following parts:

.- Toothed crown of the differential (3), free rotation and located on the outside of the tube (2) and involving an upper arm of the differential (4), which bears at its free end a vertical axis (5) where it is located the crown (6) and at its opposite end involves an arm lower part of the differential (7), which bears at its free end a vertical axis (8) where the crown (9) is located.

.- torque input (1) of the motor power transmitted by the power input crown (2) that meshes with the gear ring of the differential (3)
