[0002]
[Prior art]
Currently, landing from a ship to the beach is performed using a landing craft, a hovercraft or a helicopter.
[0003]
Landing craft type landing vessels have shallow drafts, so they can land on the gently sloping coast, but because of their shape, they are slow and because the draft is shallow and very heavy. It has the disadvantage of only limited movement.
[0004]
High-speed boats inevitably have a deep draft, so they cannot approach the gently sloping coast.
[0005]
In addition, when a helicopter is used to land a vehicle from a ship, a special ship equipped with a platform becomes essential, and its transportable load is limited. This is a major drawback when landing landing armored vehicles, especially tanks.

[0014]
According to the attached drawings, the ship of the present invention has a catamaran shape, and its left and right bodies 10 and 12 are connected to each other at the ends and at the top by beams 11 and 13. With this structure, the assembly can be maintained firmly independently of the movable platform 15 described below. In the embodiment shown in the drawings, the two fuselages 10 and 12 are also separated by bottom cross members 16 and 17 at the bottom and at their respective ends in the shaped keel area of the fuselage 10 and 12. Connected, these cross members 16 and 17 are preferably wing-shaped and can enhance the partial push-up effect that ensures a relatively high speed. As shown in FIG. 6, these cross members 16 and 17 are provided with a movable flap 21, and as a result, the equilibrium state of the traveling ship can be adjusted by the state of the center of gravity and the sea. These flaps can also be used as stabilizers for high speed navigation, especially in rough seas.
[0015]
The movable platform 15 is manufactured in a watertight box and is located between the fuselages 10 and 12, the upper part of which is shown as an armored vehicle in FIGS. 1-4 and in FIG. 6 is a running surface that supports the load shown as a truck. Form. Since each end of the movable platform 15 has deployable ramps 18, 19, the platform 15 and ramps 18, 19 constitute a loading path of uniform width equal to the spacing between the two fuselages 10, 12 ( (See FIG. 4). Preferably, the lamp is of the deployable double fold type. In the folded position, the ramp protects the cargo transported by the ship from waves and splashes (see FIG. 3).
[0016]
When the fuselages 10 and 12 are connected at the bottom by crossing members such as 16 and 17 (see FIG. 6), this crossing member is nested underneath the platform when the movable platform 15 is in the lowered position. Settle and protect them when “bringing” (see Figure 2).
[0017]
The vessel also has lifting means, schematically shown as 20 and 20 ', which are designed so that the platform 15 can be brought into an ascending or navigating position and a descending or landing / loading position, respectively. The boxes that make up the platform in the latter position provide additional buoyancy, thereby reducing drafts and enabling berthing.
[0018]
According to one embodiment of these lifting means, they are of the type mechanically guided by articulated arms, can be locked in the raised and lowered positions and can be actuated in both directions. This two-way operation can also be achieved, for example, using a double-action ram or using a warm and rack type system. The movement of the platform is controlled from the bridge.
[0019]
In the embodiment shown in FIG. 6, 24 indicates a system for guiding the movable platform 5, which is a mechanical guide system on rails, or a connecting arm as described above, or alternatively a chain or other It can be a suitable device. FIG. 6 schematically shows a device for locking the movable platform 15 in the raised position 22 or the lowered position 23. These devices can be manufactured with pins, retractable brackets, mechanical latches or other suitable systems.
[0020]
According to the present invention, the two-way actuation mechanism schematically shown at 25 in FIG. 6 is a return ram that acts directly on the movable platform 15 or via the articulated arm, instead of a rack. It can be in the form of a gear type motor device for driving a chain, a winch for operating a cable, and further driving a chain. To achieve this goal, a combination of the systems or other means of providing power in two directions may be used.
[0021]
Propulsion is preferably provided by a hydrojet with a directional nozzle and a reversing nozzle to provide excellent maneuverability and a very short stopping distance. These hydrojets (not shown) are arranged symmetrically on the two bodies 10 and 12, well above their bottoms. It is also possible to provide left and right reaction propulsion engines (thrusters) at the front of the fuselage to easily control the ship in the left-right direction.
[0022]
During sailing (FIGS. 1 and 3), the vessel of the present invention has an outer shape for sailing with two shaped fuselages 10 and 12 that maintain high speed even in rippling seas. The cargo is carried on a platform 15 located at the top of the fuselage and protected by bow and stern ramps 18 and 19.
[0023]
When approaching the coast (FIGS. 2 and 4), the platform 15 is lowered to the bottom of the fuselage 10 and 12, at which position the platform provides additional buoyancy to the vessel, which causes the draft to shallow to a sufficient value. Can approach the edge of the coast, after which the ramp 18 is deployed and personnel and vehicles can be landed in a conventional manner.
[0024]
It can be seen that the platform 15 and its ramps 18 and 19 constitute a loading passage having a uniform width and are suitable as equipment that is arranged in a straight line as much as possible as a raft for a transport landing craft.
[0025]
The device of the present invention can be used for any rapid transportation of personnel, equipment or vehicles by sea or river, for example as described below. That is,
-For transport of environmental protection equipment that can transport civil protection equipment to any point on the coastline or riverbank;
-For transport for humanitarian purposes along coastlines without berthing equipment;
-For transport and landing of military equipment and personnel;
-For river or marine transport in the case of facilities with little or no harbor facilities, but limited or very shallow (draft);
-For the transport of products from a vessel anchored offshore to the coastline or riverbank of a very shallow facility with no or even a port facility;
This is the case.
[0026]
【Effect of the invention】
The advantages provided by the ship of the present invention are in particular as follows. That is,
-The ability to obtain important navigation speeds even in rough seas when the platform is in the raised position;
-Reduce the critical draft that can be very close to the coast by placing the loading platform with the running surface above the water surface in the lowered position, and further reduce the amount of water that must be cut through by the presence of the front ramp. Can do;
-Excellent maneuverability in navigation and landing positions;
-A wide buoyancy surface in "berthing" mode to give a high sensitivity to the center of gravity and a great deal of flexibility in the way the load is delivered; and-a flap 21 in the shaped lower cross members 16 and 17; These flaps are shaped to adjust the equilibrium state of the sailing ship according to the center of gravity and sea conditions, and these flaps can be used as stabilizers,
It is.
