Description

[Detailed explanation of the invention] Industrial application field This invention relates to a target ship.
It is used as a target ship by the Defense Agency and others for live-fire training and missile launch training.

Conventional technology In conventional target vessels of this type, an unmanned vessel with a normal single-hull shape is towed by another inspection boat a certain distance using a towing rope, and a training vessel conducts shooting practice toward the target. was doing. There are also unmanned, self-propelled target ships that are radio-controlled, but because they are large and integrated, each ship is expensive, and they are considered to be unsuitable for practical use as target ships for target practice, as they are treated as consumable items. There is.

Problems that the invention aims to solve As mentioned above, conventional target ships, both towed and self-propelled, have a normal single-hull shape, so they cannot be used on rough seas such as target practice areas. However, there were various limitations in terms of seaworthiness and stability, and the target ship's speed was at most around 10 knots. However, given the rapid progress in defense technology, there is a problem in that targets of around 10 knots are no longer suitable for training. In addition, conventional target ships are relatively large and one-piece units, so in order to use them for shooting training, it is necessary to tow or guide the target ship to the training area in advance, which requires a lot of effort. The problem is that it would require a separate ship, and the cost would be enormous. The present invention attempts to solve these problems. In other words, this plan has excellent wave resistance and stability, can achieve high speed suitable for training, is inexpensive, and is easy to handle, so it can be operated by one's own ship without the assistance of consort ships. The purpose is to provide a target ship on which training can be conducted.

Means for Solving the Problems In order to achieve the above object, the target ship of the present invention has one small hull and the other small hull arranged in parallel, and is located between the small hulls. The vessel is a twin-hulled type having a skeleton member that removably connects the two hulls via an intermediate floating body, and the intermediate floating body has a built-in radio control device and a removably attached radio control device. Paul and
It has a target radar reflector removably attached to the pole and a radio control antenna,
Moreover, the internal cavities of both of the hulls are filled with closed-cell foam, and each of the hulls is provided with a propulsion device that is removably attached.

Function Since the catamaran type hull shape is adopted, in other words, it is a twin-hull type, it has good wave resistance and righting performance, and is stable even at high speeds. In addition, since it is a small assembly type and skeleton type, it has less impact from waves, etc., and can be assembled on your own ship, and can be lowered to the sea using a small lifting device equipped on your own ship, and can be towed. Since it is self-propelled and radio-controlled, it can train without the need for assistance from consort ships. In addition, the hollow space inside the hull is filled with closed-cell foam, so even if the hull is damaged, there is little chance of water intrusion, and there is no risk of sinking, so it can be recovered, repaired, and reused. .

Embodiment The drawing shows an embodiment of the invention. In the drawings, 1 is one small boat body, 2 is the other small boat body, 3 is an intermediate floating body, and 4 is a skeleton member. That is, one small-sized hull 1 and the other small-sized hull 2 are arranged in parallel to form a double-hull type, and both small-sized hulls 1 and 2 are provided with a fuel tank, etc., inside. The empty spaces are filled with closed-cell foam to prevent the building from sinking due to flooding, even if it is damaged. Similarly, the intermediate floating body 3 is provided with a radio control device inside, and the other spaces are filled with closed-cell foam. The frame member 4 is a connecting member that connects the small hulls 1 and 2 with the intermediate floating body 3 in between, and maintains the shape of the whole as a whole. In other words, it is possible to assemble and disassemble it on your own. 5 is the intermediate floating body 3
It is a pole that is removably attached to the top, and is appropriately held by a stay 6, and a radar reflector 7, a radio control antenna 8, etc. are removably attached to the top. It is filled with foam to prevent it from sinking due to flooding, even if it is damaged. Similarly, the intermediate floating body 3 is provided with a radio control device inside, and the other spaces are filled with closed-cell foam. Also, the skeleton member 4
is a connecting member that connects both small hulls 1 and 2 with the intermediate floating body 3 in between, and maintains the shape as a whole, and the connecting part is detachable by screw connection or bolt nut connection, etc. In other words, it is possible to assemble and disassemble it on your own. A pole 5 is detachably attached to the intermediate floating body 3 and is appropriately held by a stay 6.
Radar reflector 7 and radio control antenna 8 on top
etc. are attached removably. Furthermore, the rear portions of the small hulls 1 and 2 are equipped with a powerful propulsion device such as an outboard motor 9.

The target ship configured as shown is floated on the sea surface 10, and can be guided and navigated in any desired direction by radio control. Therefore, this embodiment is made up of simple elements as shown in the figure, and each element is made small and lightweight, so it can be carried out in a short time by a small number of people even in a cramped space such as on your own ship. It is designed to be assembled and disassembled.

In other words, in the past, consort ships would go out of their way to the training area, set it on the sea surface, or tow it, but only the training ship would go to the training area, assemble it on its own ship in the training area, lower it to the sea, and conduct radio communication. You can practice shooting while navigating the target ship. In addition, in the case of training methods that do not involve radio control, such as firing training using an onboard helicopter while being towed by your own ship, all training can be done on the training ship alone, and there is no need to dispatch consort ships that are not involved in direct fire training. be.

Effects of the invention The target ship of this invention has good wave resistance and recovery performance because it is a twin-hull type, and is stable even at high speeds. It becomes possible to treat it as a consumable item as a target ship. Moreover, since the two small twin-hulled hulls are removably connected using skeleton members, it can be assembled and disassembled by a small number of people in a short period of time, even in a confined space on your own ship. Since it is self-propelled by piloting, it can guide navigation in any desired direction and does not require assistance from consort ships.
Its cost is significantly reduced. Furthermore, since a target radar reflecting device is provided on a pole that is detachably attached to the intermediate floating body, target shooting training can be performed using the reflecting device as a target, which is useful for early improvement of the training. Moreover, since the internal cavity of the small hull is filled with closed-cell foam, the increase in weight due to the foam is negligible, and even if the small hull is damaged, it will not be damaged due to water ingress. Because there is little risk of sinking,
There is a high probability that it can be recovered and repaired and used again.
