Definitions

  • the present invention relates in general to partially submerged thrusters and in particular to thrusters mounted on the hull of vessels and movable relative to this hull.
  • the prior art thruster comprises at least two propeller propellers mounted on propeller shafts forming an angle of 45 ° ⁇ ⁇ 70 ° relative to the central longitudinal plane of the vessel, which propellers have propeller blades whose configuration allows them during their rotation around the trees to place their attack face normally with respect to the central longitudinal plane of the vessel as the attack faces longitudinal center of the vessel as the attack faces are submerged.
  • the attack face of each blade is driven in an axial movement relative to the water and is supported by a reaction thrust.
  • the present invention aims to overcome the difficulty presented by partially submerged propellants of the prior art and improves the characteristics of these propellants by modifying the mechanical propulsion links between the propellant and the hull of the vessel.
  • the present invention has solved this problem by proposing a partially submerged propeller constituted by a propulsion shaft placed in an angular position relative to the central longitudinal plane of the vessel and by partially submerged propeller blades mounted on the propeller shaft and studied so that when immersed in water their attack faces occupy an essentially normal position relative to the central longitudinal plane of the vessel in which the propeller blades of the propellant according to the present invention are mounted to make vary their position relative to the central longitudinal plane and / or the plane of the median section of the vessel.
  • the propeller blades can be placed in any position. This is due to the fact that the propeller shaft can take a combination of positions at various angles to the central longitudinal plane and to the plane of the molded base of the vessel and to the fact that the propeller blades can be placed in various positions simultaneously with respect to these planes.
  • propeller blades mount the propeller shaft so that they can be adjusted by ⁇ 30 ° on each side of the normal to the axis of the propeller shaft and also ⁇ 30 ° on either side of the normal with respect to the axis of each propeller blade in its initial position.
  • One of the embodiments of the present invention may advantageously include propeller blades mounted on a propeller shaft which rotates about an axis perpendicular to the plane of the molded base.
  • the propeller shaft of the new propeller and the propeller blades mounted on this propeller shaft can be positioned (on the bow hull and / or the stern hull of the vessel for all draft , any speed of movement, for various maneuvers, etc.) and, in an emergency, we can make the most of the repelling force of the water to move the vessel forward, laterally or backward without changing the direction and speed of rotation of the propeller shaft.
  • the propellant according to the present invention improves the efficiency, the speed, the maneuverability and the safety of ships and other types of vessels, self-propelled landing strips, offshore platforms, etc. It is on air-supported vessels of the propeller shaft type at the front or rear and occupying a position within a range of 0 ° to 90 ° relative to at the longitudinal center plane of the vessel that the effect of these characteristics is most marked.
  • a propeller with four propeller blades with variable position usable on the vessels studied to be supported by the dynamic action of water or by air is constituted by blades d '' rotary propeller 1 mounted on the aerodynamic part of the hub 2 of a fitted propeller shaft, as well as a unit of reduction gears and a mechanism allowing the rotary adjustment of the propeller blades in a casing 3
  • the upper part of the casing 3 and the hollow telescopic support 4 are connected by a rotary articulation to allow the casing 3 to rotate in both directions along the line 5 within a range of 0 ° to 90 ° .
  • the hollow telescopic support 4 is arranged in a housing 6 which, at its upper part, pivots in the hull of the ship 7 using lugs 8 while its middle part pivots around a mechanism 9 which makes it possible to tilt this accommodation 6. It is possible to equip vessels with various types of propeller blades of various shape and constitution.
  • the propeller blades can be either hydrofoil type blades such as the blade 10 shown in Figure 2 or conventional propeller blades like the blade 11 (shown in dotted lines in Figure 2).
  • vehicles with a large air cushion can use two-position or multiple-position thrusters comprising two sets of propeller blades 12 or more spaced apart on the propeller shaft.
  • the propeller blades 12 can be immersed in water at any depth and can be adjusted by rotation along line 14.
  • a thruster with two or more blades with variable position can have blades of the shape of the blade 15, and thus forming a configuration with several blades interconnected side by side and spaced apart on the shaft d propeller 16 by spacer rods 17.
  • the thrusters with variable position can be mounted on the high seas platforms 18.
  • two thrusters can be used coaxial rotating simultaneously in opposite directions and equipped with acinaciform propeller blades 24, mechanism 25 for rotating and adjusting the propeller blades 24, mechanism 26 for raising and lowering the propellants and making it possible to reach the optimal position of the propeller blades 24 in the water when the boat is lifted out of the water by the hydrofoils 27.
  • a plate serving as a safety apron 28 is placed above the propellers.
  • the propellants according to the present invention can be of the hydrofoil type.
  • Such propellers can be used on convertible planes such as twin-engine structures 29, four-engine structures 30 and multi-engine structures, all of these structures being fitted with conventional wings 31 and retractable wings 32.
  • the propeller blades 33 are mounted on rotary hubs 34 of the propeller shaft. These hubs can be adjusted using the mechanism 35 to raise or lower the hubs to the position which is suitable for starting, sliding, displacement and air support of the convert-plane, or else for taking it off.
  • the pulling force on the towing cable exerted by a propeller blade that moves in water depends on the angle of inclination of the direction of movement of this propeller blade relative to the plane of the median section of the ship.
  • each propeller blade 41 considered separately during its movement in the direction of the dotted arrow 42 accelerates the bodies of water in this direction with the force represented by arrow 43.
  • the propellant rotating on its axis, the action of the two propeller blades 44 and 45 which diverge from a common point 46 when they are in the water is represented by the arrows in solid line 47 and 48 which indicate the direction and the acceleration force of the water (to give the traction force made up of the propeller), arrows 49 and 50 showing the direction and the force, except for the acceleration of the water, the mixing and the rejection of the water around the edge, ie the force represented by the arrows 49 and 50 which represents the losses due to the rejection and mixing of the water, which are substantial in conventional propeller thrusters and practically non-existent in thrusters according to the present invention.
  • the force of traction when the direction of movement of the propeller blades according to the present invention in the water changes within the range of 0 ° to 90 ° relative to the plane of the median section of the vessel the force of traction also changes.
  • the traction force When the propeller blade moves from position 51 to position 52 (in the plane of the median section of the ship) the traction force is nonexistent and this force does not develop until the propeller blade is passed from position 51 to one of angular positions 53 to 58.
  • the tensile force was 37%, 68%, 91%, 99%, 81% and 55% of the maximum force bollard pull at angular positions of 15 °, 30 °, 45 °, 60 °, 75 ° and 90 ° respectively.
  • the above data are the results of the experiment represented on the curve of the percentages of bollard traction force / direction of movement of the propeller blade relative to the plane of the median section of the vessel.
  • One of the characteristics of the propeller according to the present invention is that it can be used as an "active rudder" when the propeller blades rotate around their own axes.
  • the propeller shaft occupies a position which forms an appropriate opening angle relative to the central longitudinal plane of the vessel, for example 45 °, while the propeller blades are immersed at 2/3 of their height and are placed in position 51 (figure 17) in preparation for start-up.
  • the propeller shaft When the propeller shaft begins to rotate to position 55, it develops a propelling force as the water accelerates in the direction of the arrow in solid lines. The propeller blade undergoes a reaction force during its movement in the water and slides along the pressure front.
  • the propeller during its revolution on the propeller shaft, moves in the manner described only when it is submerged in water but while it enters water and leaves water it is inclined, therefore, practically in all cases the propeller blade partially pumps down the water of a revolution during the first phase and raises it during the second phase. But as at any moment another blade moves in the water this water does not rise any more. In addition, the blade escapes by sliding.
  • the propellers according to the present invention operate in the same way on the convertible planes ( Figures 13 and 14).
  • the propeller shafts form an angle with the plane of symmetry of the convert-plane and the propeller blades describe viewed from the front or seen from the front. 'rear of the ellipses shown in dotted lines in Figure 13.
  • the propeller shafts of the twin-engine structure After acceleration and before takeoff, the propeller shafts of the twin-engine structure are almost parallel to the plane of symmetry and the propeller blades are close to the transverse vertical plane. It is only when the propeller shaft takes a position parallel to the plane of symmetry and the speed of rotation of the motor increases suddenly (to reduce the tendency to accelerate as the advance decreases) the convert - twin-engine plane takes off.
  • a four-engine convertible plane can also take off while its two interior thrusters operate in water (Figure 13), its two other thrusters already operating out of the water to rely on the air reaction thrust.
  • the blade-shaped thrusters operate in a manner identical to that which has been described above for propeller blades.
  • the blade-shaped propellers are different in that they have no gaps between the blades and while the propeller shaft rotates in the direction from the dotted arrow in FIG. 5, the water accelerates in the direction of the arrow in solid lines and therefore causes the displacement of the vessel in the opposite direction.
  • the band-shaped thrusters used on offshore platforms allow these platforms to perform any maneuver (forward, aft, rotating and lateral on either side) .
  • the thrusters of the present invention can be used on offshore platforms, floating power plants as well as sea and river boats moving at high speed (200 to 400 km / h). It is also possible to use them on outboard motors, on vehicles with air cushions and on convertible planes.
