Description

The invention relates to a ship training as a simulation clearing vehicle for active anti-mine defense for receiving arrangements for generating physical ship signatures, in which a bond is formed from individual coupled ship segments in a shock-proof design and the ship segments are connected via connecting elements between adjacent connecting surfaces and in the event of shock loads against one another are adjustable, wherein a hull is formed from ship segments assembled according to the requirements.

Such an arrangement can be simulated according to DE-PS 977 936, the ship signatures with respect to acoustics and magnetics individually or in combination. The problem it is also to simulate the pressure, so that a deception regarding the ship signatures of pressure, acoustics and magnetics of the ignition systems of modern mines is possible. Another problem is to design a carrier that can withstand these high loads from the mines detonating in the immediate vicinity.

It is recognized in this area that in the future simulation room systems will only be successful if they generate all target ship signatures as similar as possible to ships. It has been shown that not even the so-called barrier breakers can be used accordingly, which, apart from the necessary modifications, can become a ship obstacle if the mine is successfully detonated.

Furthermore, according to patent application P 39 39 788 it is known to form a closed hull which, in the event of a lightning strike, ie. H. if the loads on the ship structure are greater than the normal swell loads, a diversion of individual ship segments is guaranteed.

It has been shown, however, that the pulse-like triggering in the event of a detonation means that it is not possible to adjust the ship segments against one another, since compensation with an axial displacement, shortening the arrangement, in the event of a shock, in the time unit required to avoid damage to the ship segment is not possible .

The object of the invention is to improve a generic arrangement and to provide a simple arrangement which ensures coupling of the ship elements and evasion of the ship elements enables each other in the event of a blast for damage-free energy destruction.

This object is achieved according to the invention in that the connecting elements are each formed by receptacles and corresponding tabs which are in engagement with one another and in the bottom region of the receptacle the tab can be connected to an associated tensioning unit for axial deflection and adjustment of a pretension and that the tab have free spaces in the receptacle for adjusting the tilting movements of the ship segments to form a flexible joint, at least horizontally above and below the bracket, which accommodate prestressed holding elements for a central position of the bracket.

The main advantage of this arrangement is that it allows the ship elements to dodge each other in the event of a lightning attack and thus allows ship elements to emigrate in a simple manner.

An advantageous embodiment of the invention is that the receptacle and tab are wedge-shaped as corresponding elements and in the bottom region of the receptacle the clamping unit can be connected to the tab via a pivot axis.

In order to achieve good guidance of the connecting elements in the event of a deflection, it is proposed according to the invention that the bottom area of the receptacle is designed in the manner of a link guide into which the tab can be slidably received with an associated guide element in the tip area, the guide element and tab being connected via a Bolts are pivotally connected.

A simple arrangement is created in that the tensioning unit and holding elements are designed as force units in the form of pneumatic or hydraulic cylinders and a preload that can be overcome can be set for the starting event.

In order to achieve favorable guidance, it is provided that the connecting elements take up at least a third of the ship's width.

In the arrangement shown, ship segments 1 are assembled to form a ship's hull in a shock-proof construction in accordance with the requirements. The individual ship segments 1 are coupled via connecting elements consisting of a receptacle 2 and a tab 3 in a corresponding design in order to enable the ship segments 1 to be adjusted relative to one another. The receptacle 2 and the tab 3 are designed in a wedge shape for simplification when the ship segments 1 are joined together by floating in, a large inlet opening 4 being assigned to a small tab tip 5 during the floating in process.

In this embodiment, a guide in the manner of a link guide 6 is formed in the bottom area of the receptacle 2 and the tab 3 has an associated guide element 7 in the end area which can be slidably received in the link guide 6. The guide element 7 and the tab 3 are pivotally connected via a bolt 8. The tab 3 or the guide element 7 additionally carries a connection receptacle 9 which can be connected to a receptacle element 12 via an insertable bolt 10 with a clamping unit 11, for example in the form of a pneumatic cylinder. The connection pin 10 is brought into engagement after the assignment of the ship segments 1 and the engagement of the tab 3 in the receptacle and reaching its end position via a control cylinder 13 for coupling the connection receptacle 9 and the receptacle element 12.

An axial pretension is then set via the tensioning unit 11, which assigns the ship segments 1 accordingly for normal operation.

When the tab 3 is inserted, the receptacle 2 forms free spaces 14 in the middle position above and below the tab to enable movement of the ship segments 1. These free spaces 14 are bridged by prestressed holding elements 15 by engaging the tab 3 on both sides. These holding elements 15 are designed, for example, as pneumatic cylinders and, like the clamping unit 11, are preloaded accordingly. As a result, the ship segments 1 are assigned in accordance with the specification in normal operation.

According to FIG. 8, control of the tensioning unit 11 is shown. Here, the tab 3 is held by a piston 16 by the pressure of a compressor 17 with a biasing force Fv corresponding to the forces occurring in the normal operating state of the ship, in particular this force is measured according to the thrust of the propulsion system. In the event of firing by mines, the set axial preload is overcome, the piston 16 clears an axial path, so that an adjustment of the ship segments 1 to carry out a sudden shortening of the arrangement is not hindered and thus the occurring sprinkling forces within the predetermined range without damaging the ship segments 1 stay. After the firing process has ended, the starting position is restored.

In order to maintain the central position of the tab 3 in normal operation, the control of the prestressed holding elements 15 is shown in FIG. 9. Here, a piston 18 by means of a compressor 19 with a Biasing force Fv biased according to the normal operating condition of the ship. When the pretensioning force Fv is exceeded by a force F that occurs from the outside during a singeing operation, the piston 18 is moved and the pretensioning pressure is increased in accordance with the reduction in volume. In this case, an additional buffer container 20 is connected to the piston chamber for compensation. When the force F subsides, the piston 18 returns to its initial position and the original center position is restored.

The pretensioned tensioning unit 11 and the holding elements 15 thus enable the coupled ship elements to move in relation to one another in the desired manner in the event of a lightning and the normal operating behavior is ensured in the other case. In this way, the scorching that occurs as a step function is mastered by compensating for the movement of the ship segments 1 in order to avoid destruction.
