Definitions
- This invention is used in the field of marine ships, more precisely in the propulsion and movement of ships, and it is suitable for all sizes of ships, starting from small ships to giant ships.
- This invention aims to rotate the ship's propeller with compressed air, because rotating the propeller with compressed air significantly reduces the amount of energy lost when transferring power from the engine to the propeller via the shaft connecting them, because this invention avoids stopping the ship of the large size From moving in the event of engine failure, because large ships have large engines and in the event of failure of these engines, the ship is unable to move, and because our invention made the transmission of power to the propeller by means of compressed air through pipes, the engine failure in our case can be easily circumvented by operating an air compressor of spare, and our invention reduces fuel consumption because we can store an amount of compressed air in tanks as needed, because this storage constitutes a force that can be released giving us great power comparable to the power of large gas engines. certain floors.
- Figure 1 This figure shows the longitudinal section of the ships propeller which works with compressed air, or this figure shows the carrier cylinder (1) which is installed on the hull of the ship and we put the rest of the propeller components , the stirring disk chamber (2), the compressed air tubes (3), the transmission shaft (4) between the stirring disk and the propeller, the propeller (5).
- This figure shows the cross-section of the stirring disk, showing its internal parts represented by the disk (6), and the compressed air chambers (7) which are four chambers, and the grooves on the edge of the stirring disk (8).
- the essence of the invention of the ship propeller that works with compressed air is the transfer of power to the propeller by means of compressed air, because this invention allows us to install the ship propeller at any place we want, regardless of the location of the engine that produces compressed air, and also this invention reduces fuel consumption, where we can store an amount of compressed air in tanks, and when necessary, we release a quantity of this compressed air so that it gives us great power comparable to the power provided by large engines for some time, and the rotation of the propeller with compressed air allows us to save an amount of energy which was wasted during its transfer from the engine to the propeller through the propeller shaft between the engine and the propeller, and our invention consists of a hollow cylinder at the inside which we install the propeller and the stirring disk and it is connected to the compressed air pipes, since this allows us to install the propeller that works with compressed air at any point of the hull of the ship because the energy that drives this propeller arrives through pipes, because the compressed air that reaches the stirring disk turns this disk, which in turn turns the propeller, which gives us the thrust to
- the hollow cylinder in which we install the rest of the elements is of a optional diameter and is equipped in such a way that we can install it on the hull of the ship.
- the mechanical system of the stirring disk and the pressure chambers is what transforms the compressed air into a rotating motion, because the stirring disk has grooves on its edge, and these grooves are semi-circular in shape like indicated in the list of figures, figure -2-, and these grooves are of small size dimensions II is between one and ten thousandths of the diameter of the stirring disk, and the shape of the pressure chamber is the shape of a parallelepiped, because it is hollow in the shape drawn in the list of shapes Figure -2-, as this shape allows us to install the stirring disk so that part of it is inside the hollow part of the pressure chamber, where the distance between the stirring disk and the pressure chamber allows rotation without friction and with the least possible distance at the places where there is contact between them, and the pressure chamber has a groove which is a quarter of the length of the pressure chamber, and it is square in shape whose
- the propeller of a ship that operates on compressed air works as follows: after installing the hollow cylinder on the hull of the ship, and after installing the stirring disk and the propeller inside, we connect the compressed air tubes to the four pressure chambers, and on the other side we connect the compressed air tubes to the ship's air compressor, we turn on the air compressor, and when we want to move the ship, we allow the compressed air to flow through the pressure tubes to the four pressure chambers, when the compressed air reaches the mechanical system as shown in figure -2 -, since the compressed air inside pressure chambers form a force that pushes in all directions and since the surface of the stirring disk is the moving surface, this makes the compressed air pushes the stirring disk to rotate and it is assisted by the grooves on its edge, and the groove in the pressure chamber allows compressed air to escape unhindered. This gentle exit from the air through this groove makes the movement of the compressed air inside the pressure chamber in the direction of rotation, and by this we have reduced the amount of compressed air used to rotate the drive disc and thus reduce fuel consumption.
