DD300658A5 - Carrier for sea-level towing discs - Google Patents

Abstract

The invention relates to a multi-hull carrier for sea-target towing discs, preferably for use in artillery shooting at sea. The Schwimmkoerper consist of several buoyancy cells, which are easily loesbar arranged on a connection frame and conditionally interchangeable. By installing suitable splinter protection decks in the buoyancy cells special protective spaces for receiving parts of the sensor technology of the target can be created. Shake-damaged buoyancy cells can also be released from the composite in the floating state, replaced or repaired and re-inserted into the composite.

Field of application of the invention The invention relates to a carrier for Seezielschleppscheiben, preferably for use in Artille rießfechtsschießen at sea. Characteristic üss prior art Monohull or Mehrrumpfschwimmkörper with arranged thereon target for use at sea are known Imitation of floating goals. From the production program of the VEB Yachtwerft Berlin are catamaran floating bodies for Seezielschleppscheiben known in which the floats are attached to the connecting structure inextricably and

the floats are filled with foamed plastics to achieve a high sinking safety.

In SU-PS 895783 a Wassersportkatamaran is described, for the purpose of easier handling during transport

can be folded.

From US-PS 3981259 and 4079688 floats, for example, for catamarans are known which by change

the arrangement geometry can be adapted to current operating conditions, for example, to improve the stability or to increase the speed.

Furthermore, in US-PS 4189148 a towed target display ship with immersed body described in the Contrary to multi-hull arrangements the upright floating position through active and / or passive control equipment

is reached.

In addition, a technical solution is shown in DD-PS 203761, in which standardized large container temporarily Floating bridges, translating ferries and similar floating structures combined to form a stable floating unit

can be.

The technical solutions shown have disadvantages for the intended application, which in the following

to be named:

- conventional single- and multi-body floating bodies for targeting purposes must be slipped, docked or otherwise dried to carry out necessary repair welds (bombardment damage),

- Repair welds on foamed floats also cause environmental problems,

the possibilities for changing the arrangement geometry as well as for simplifying the transport do not contribute to the increase in the safety of sinking or to the simplification of the repairs,

- The use of large containers as a float for the use of Zielorfstellungsmicteln forbids on the one hand for ship hydrodynamic reasons (resistance) and on the other hand due to the too large silhouette · (probability of hit).

Object of the invention

The aim of the invention is to provide carriers for Szielzielppscheibe, which are highly safe to sink, grout over bulletproof rooms and can be repaired without the use of slip or dock capacity on board combat / support vessels.

Explanation of the essence of the invention The object of the invention is to propose a multi-hull carrier for Seezielschleppscheiben. According to the invention the problem is solved uuuurch that the floating body of several individual, due to each other

interchangeable, not directly interconnected and easily releasably attached to a connection frame

Buoyancy cells exist. The global mechanical strength of the carrier is realized by the connection frame

and created the possibility to solve broken by buoyancy buoyancy cells, inter alia, in the floating state of the composite and replace or repair.

According to the invention is further that by the arrangement of splinter protection decks at a suitable location below the Floating-water line in the buoyancy cells, bullet-proof spaces are created, which absorb sensitive parts

serve the sensor technology of the target.

AusfQhrungsbelsplele

The invention will be explained in more detail with reference to FIGS. 1 to A. Show it

1: the view from obon (main view) of the embodiment of the carrier according to the invention, Fig. 2: side view, the Stb.- and Bb.-views are identical,

Fig. 3: front view, the view from the rear is identical from the front,

Fig. 4: section through a buoyancy cell.

Fig. 1 shows the main view of the carrier for Seezielschleppscheiben invention. On the connection frame 6, the main, intermediate and bow / stern buoyancy cells 1, 2, 3 are releasably fastened using the connecting elements 4, 5.

On the connecting frame β one or more foundations 7 are arranged, which serve for receiving masts, target presentation means / devices or the like. The main buoyancy cells 1 Wio and the intermediate buoyancy cells 2 and the bow / Heckauftriebszellen 3 are identical in shape and dimensions and interchangeable. The gap 8 between the buoyant 1.2,3 is dimensioned so that when elastic deformation of the connecting frame 6, for example by sea, the contact of the buoyancy cells 1,2,3 excluded each other

FIGS. 2 and 3 show the different shapes of the main, intermediate and bow / stern / tail cells 1, 2, 3, which is a prerequisite for the hydrodynamically favorable shape of the overall arrangement.

4 shows the arrangement of a splinter protection deck 9 within a buoyancy cell 1,2, £ below the floating water line 11, so that below the splinter protection deck 9 a bullet-proof space 10 is formed.

Necessary equipment / equipment for towing / towing the sea target disc is preferably attached to the connection frame 6.

When using a sea-to-target disc for combat training at sea, there is a high likelihood of damage to the wearer's floats by fire. By using the solution according to the invention, it is possible to repair damage caused by fire to the floating bodies which limit the buoyancy of the target, with on-board means of the towed ship or by nearby combat / support vessels. For this purpose, for example, a damaged buoyancy cell is released from the Vorbund the carrier and heaved with Bordhebezeugen from the water. In the event that the towing vessel / boat carries reserve buoyant cells, they can be inserted in place of the damaged ones in the composite. This guarantees a high level of operational readiness and availability of the sea-going towing disc at all times.

The solution according to the invention also ensures a hydrodynamically favorable shape of the float, excludes restrictions on the driving / towing direction and ensures a high level of stability and sinking safety impact hit.
