Definitions
- the present invention relates to a new type of propulsion device for a ship (term taken in the broad sense and designating both surface ships and submarines); it also relates to a new type of ship fitted with such a propulsion device.
- a ship propulsion device comprising two concentric propellers and contra- rotary, rotating at the same speed but in the opposite direction, with reversed steps, said propellers being driven by two drive shafts, coming either from two heat engines, one of which rotates in opposite directions to the other, each driving a drive shaft, either of a cam engine having the characteristic of comprising two concentric drive shafts, rotating at the same speed but in opposite directions, such a drive making it possible to suppress any reaction torque of the ship around the axis of the propellers, the couples of rotation of the propellers being zero as well as those of one or both engines.
- the invention therefore relates to an improvement made to a ship propulsion device comprising two concentric and counter-rotating propellers of the aforementioned type, which is essentially characterized in that the concentric and counter-rotating propellers are placed inside a cylindrical hull making it possible to avoid cavitation and the formation of vortices generated by each propeller and which is arranged in such a way that the outlet walls of this hull constitute a thrust reverser by closing the water outlet and opening either in two, either in corolla, to reverse the direction of water flow and constitute the reverse gear.
- the hull which envelops the two counter-rotating propellers is cylindrical at the height of the two propellers, then becomes square or rectangle so that the upper and lower horizontal sides are fixed, integral with the hull, and the straight vertical sides and left are movable around a vertical axis, resting on the horizontal sides, so that the pilot can, according to his order, transform this hull, either in reverse gear, or in a means of lateral displacement of the ship , either by rudder by changing the angle of the water outlet;
- the two concentric and counter-rotating propellers are placed inside a duct connecting the bow to the stern of the ship or submarine, so as to improve propulsion; - when such a device is implemented on a submarine, the front, the center and the rear of said submarine have substantially the same dimensions, so that the flow d can be circulated water driven by the propellers in a duct closed by the walls of the submarine and an outer casing in order to absorb the volume of water generated by the displacement of the submarine, and thus limit the turbulence of exit.
- Figures 1 and 2 schematically illustrate the state of the prior art, Figure 1 being a plan view of two heat engines controlling two counter-rotating propellers, and Figure 2 a longitudinal sectional view of a ship equipped with these counter-rotating propellers;
- FIG. 3 to 9 are schematic views of a ship propulsion assembly produced in accordance with the invention, and in which:
- Figure 3 is a longitudinal sectional view of the ship equipped with these counter-rotating propellers provided with a cylindrical hull, the water outlet walls, on the order of the pilot, are transformed into a reverser;
- FIG. 4 is a perspective view of the hull, cylindrical at the height of the counter-rotating propellers, and square or rectangle at the outlet so as to constitute either a means of lateral displacement of the ship, or a thrust reverser, or a rudder;
- Figure 5 is a plan view of the hull flaps allowing movement of the ship; .
- Figure 6 is a plan view of the hull flaps allowing rearward movement of the ship; .
- Figure 7 is a longitudinal sectional view of a ship with a conduit joining the front to the rear of the ship; .
- Figure 8, like Figure 9, is a longitudinal sectional view of two submarines with their conduit formed by a double jacket and the walls of the submarine.
- Figure 1 is a plan view of two heat engines (2 ⁇ ) and (22). Note that the motor (22) has been rotated 180 ° in order to rotate the motor (2 ⁇ ) which drives the propeller (5) through the shaft (3); the motor (22) drives the propeller (6) through the shaft (4).
- FIG. 2 is a longitudinal sectional view of the ship or submarine equipped with these counter-rotating propellers.
- the vessel (1) which is equipped with a cam engine (2) driving two concentric motor shafts (3) and (4), rotating at the same speed but in opposite directions, the motor shaft (3) driving the propeller (5) and the shaft (4) driving the propeller (6).
- the propellers (4) and (5) have an inverted pitch to obtain the displacement of the ship.
- the efficiency of the counter-rotating propellers improves the thrust and therefore the propulsion.
- FIGS. 3 to 9 illustrate different embodiments and use of a propulsion assembly of the aforementioned type produced in accordance with the invention.
- Figure 3 is a longitudinal sectional view of the ship or submarine equipped with two counter-rotating propellers rotating inside a cylindrical hull secured to the ship.
- a hull (7) integral with the ship (1) surrounds the two propellers (5) and (6), the outlet walls (8) of the hull (7) constituting a reverse gear (well known in aviation), shutting off the water outlet pushed by the propellers and opening in corolla on a part of the rear cylinder to let the water pass.
- Figure 4 is a perspective view of the cylindrical hull (7) at the height of the counter-rotating propellers and square or rectangle output so as to constitute either a means of lateral movement of the ship, or a reverser.
- the water outlet of the hull is a square or a rectangle, characterized in that the upper (9) and lower (10) horizontal sides are fixed, integral with the hull ( 7) while the vertical sides (11) and (12) are movable around the vertical axes (13) and (14).
- the flaps controlled by the pilot of the ship will make it possible to obtain either a lateral displacement, a reverser, or even a rudder by modifying the direction of the water outlet pushed by the propellers.
- FIG. 5 is a plan view of an embodiment of the hull (7) shown in the case where the pilot wants to perform a lateral movement.
- the ship (1) is provided with a hull (7) secured to the boat by tie rods (15) and (16), a cylindrical part (17) of the hull surrounds the two counter-rotating propellers (5) and (6 ), it ends with a square or rectangle part (18), the upper (9) and lower (10) sides are fixed and integral with the hull, the vertical sides (11) and (12) pivoting around vertical axes (13) and (14) fixed on the horizontal fixed sides.
- the pilot acted on the jack (19) which is connected by an arm (21) to the vertical pivoting side (12) which closes the water outlet (23) but opens an outlet (24) perpendicular to the outlet (23) .
- Figure 6 is a plan view of the hull flaps allowing rearward movement of the ship or submarine.
- the pilot acts on the two cylinders (19) and (20) to close the water outlet (23) and clear the openings (24) and (25) .
- the water reverses its direction and the ship or submarine goes in reverse.
- the pivoting flaps (11) and (12) can serve as a rudder when the pilot acts on the jacks (19) or (20) by modifying the direction of the thrust of the propellers (5) and (6), by the displacement of a single component. It follows a great simplification and an improvement facilitating the piloting.
- Figure 7 is a longitudinal sectional view of a ship with a conduit joining the front to the rear of a ship (1).
- a conduit (26) of large diameter to accommodate the two counter-rotating propellers (5,6), leaves from the front (27) to the rear (28) of the ship (1) or of the marine.
- the front (27) and the rear (28) are arranged in the form of a funnel so that the water flow formed by the advancement of the ship or submarine is absorbed by the water flow contra-rotating propellers, so as not to cause eddies.
- the motor or motors (2) which drive the propellers are placed parallel to the duct, they take the motor shafts (3) and (4) integral with the propellers (5) and (6) by four bevel gears (29,30,31 , 32), the motor shaft (4) drives the pinion (29), the motor shaft (3) drives the pinion (30), the pinions (29) and (30) drive the pinions (31) and (32 ) integral with the propellers (5) and (6).
- the ship or submarine will therefore have the same dimensions at the front, center and rear, it will not cause any eddies, which will improve propulsion.
- FIG. 8 is a view in longitudinal and vertical section of the submarine (1) with a double envelope (33) surrounding the walls of the submarine.
- the motors (2) drive the propellers (5) and (6), the upper sides (9) and lower (10) form the hull, the movable flap (11) pivots around the axis (13).
- This envelope (33) may be made of vibration absorbing materials and, as the water flow resulting from the advancement of the submarine is absorbed by the two counter-rotating propellers, there is the absence of turbulence created by the advancement of the submarine, there will therefore be very few vibrations that can be picked up by devices for detecting the presence of submarines.
- FIG. 9 is in accordance with FIG. 8, except that the counter-rotating propellers (5) and (6) are located at the front of the submarine and discharge the water pushed by these propellers at the rear. We find the same notations.
