Description

Protection device for a military support vehicle

The invention relates to a concept of protection for a medium-weight military support vehicle.

GB 543,742 indicates a possibility of providing a simple tractor with protection, except for the front wheels. This protection is made as a steel armored cover that can be placed on the wheel axles. Another form of protection shows document FR 1,189,351.

Document US 6,382,069 B1 discloses a minesweeper vehicle as a driver's cabin that is placed away from the means that the mines give off on the chassis of the vehicle, and which is made as an armored cabin mounted on springs.

The article "Kampfpanzer Leopard 2" - Online - discloses that the chassis of the Leopard fighter car is used for superstructures of an armored vehicle for embankments (Büffel), of a bridge launching vehicle (Leguan), of an exploration vehicle (Kodiak) or a minesweeper (Keiler). Medium-weight military support vehicles are designed for the support of wheeled vehicles and military chains of this type in the 25 t to 45 t weight categories, as well as as a working instrument for exploration troops. These support vehicles are divided into at least four categories, armored variants for embankments, bridge launchers, exploration and minesweepers.

Document DE 1 907 050 A1, which forms a starting point for claim 1, describes a caterpillar vehicle for military purposes. This is based on the objective of creating a track vehicle with which the total technical cost for a large number of different vehicles required is considerably reduced. In addition, the vehicle has a basic part of the vehicle for housing a large number of different superstructures. In one embodiment, an armored driver's cabin is placed on the basic part of the vehicle.

Medium-weight support vehicles are used according to known employment doctrines, together with classic employment scenarios, such as attack and positioning situations, increasingly, among other things, in peacekeeping means, in that these vehicles are also subject to a 360º ballistic threat, and are also threatened by anti-tank mines and anti-personnel mines, as well as by means of explosive traps. This fact would require omnidirectional protection of the vehicle. However, these vehicles are also subject to the requirement of being able to be loaded from the air.

In this case, the invention sets the objective of showing a protection concept with the help of which both the crew protection requirement and the requirement of the possibility of loading from the air are fulfilled.

This objective is achieved by means of the features of claim 1. Advantageous embodiments are indicated in the dependent claims.

The invention is based on the idea of providing at least the region of the adapted omnidirectional protection vehicle that serves to accommodate a crew. The other regions receive minimal protection that is designed for basic threats.

Document DE 202 21 019 U1 discloses a minesweeper vehicle with a camera cabin and a protection cell for a user. This can be integrated instead of the camera cabin, or additionally next to it in the front region of the minesweeper vehicle. The protection cell is made from a steel shell-proof armored, or from a composite material. This creates the possibility that the minesweeper vehicle can be operated either directly or remotely driven.

The fundamental characteristic of this protection concept is a separate, uncoupled, and closed crew cell. Under the floor of the chassis ship, a mine protection plate is fitted in the region of the crew's cell. In addition, the cell separates strictly from the hydraulic or chassis region. By means of this measure the danger of the crew is minimized by means of possible flammable liquid deflagrations. In the outer region the crew's celtic is equipped by means of additional belts (add-on-armor). Reactive and / or active protection modules against portable anti-tank weapons or directional mines with horizontal effect are also provided. The crew cell is equipped inside with a corrugated cardboard cover paper, which on the one hand reduces the cone of fragments of a ballistic penetration, and on the other hand it acts by insulating the sound that propagates through solid structures and Performing thermal insulation. In addition, the crew cell and / or the chassis can be equipped with reactive and active protection modules against portable anti-tank weapons and directional mines with horizontal effect.

The crew cell is hooked on suitable bearing arrangements in the chassis. Something similar is known from document DE 196 53 283 C1, as well as document DE 10 2004 026 237 A1, and document DE 10 2004 006 819 A1. Through these bearing arrangements, on the one hand, shock loads from mine detonations or explosives are decoupled, and oscillation loads or sound propagated by solid structures are also minimized.

The crew cell also has sufficiently large inspection windows and goniometric mirrors for a direct view to the outside, and also has electronic vision means, such as cameras or sensors day and night. Other cameras and sensors in the vehicle are used to transmit sufficient information from the nearby environment to the crew (similar to what happens in the construction of civil vehicles).

The inspection windows are designed as shatterproof composite safety glass against the corresponding threat, and have a laser protection filter to protect the eyes of the crew from unwanted laser light. Also provided are screens that can be lowered or folded, which on the one hand form an additional ballistic protection, and can be used against fragments, but which on the other hand can be used as passive protection when the crew space is to be obscured . Naturally, the screens also serve to prevent the reflection of light on the surface of the discs.

In addition, a kind of intercom installation must be integrated into the vehicle to prevent the crew from opening a door or a hatch in making contact with outside personnel.

The crew seats are integrated in the crew cell in such a way that they are sufficient for the requirements of the reduction of load in the mine explosion and for the decoupling of oscillations. The seats are provided with restraint systems and corresponding head protections. The crew also has, preferably, at least one hatch in the roof region, and a door preferably at the rear of the crew cell.

The crew cell also contains protection efficiencies and air preparation facilities against atomic, biological and chemical threats, as well as an air conditioning of the crew room. This makes it possible to keep the physiological efforts of the crew at reduced levels.

The chassis has, in addition to the basic protection for the survival capacity of the system, a closed hydraulic region, in which parts of the fuel installation can be placed. Both the hydraulic space and the engine space each have, on their side, a fire extinguishing installation. Firewire sensors are integrated in the suction region of the engine cooling system, which in case of an external fire causes a disconnection of the cooling fans.

Active protection measures are another configuration in the vehicle. These include, for example, a Nebel launch installation, as well as a manual or remotely controlled weapon installation. Disturbing emitters are intended to blow explosive traps away in front of the vehicle.

As a measure of passive protection, in addition to the appropriate camouflage networks, camouflage kits are also provided that reduce optical, infrared or radar signatures, or alter them strongly. In addition, engine exhaust and cooling air are shielded behind the rear of the vehicle. The additional air panels, the rear vents and the insulations serve to shield the hot gases with respect to the structure of the vehicle. The particles in the engine exhaust can be minimized by means of appropriate measurements inside the engine and / or filters.

The exploration vehicle is equipped with an excavator installation with quick-change system, and allows, as in all actions, a change of tools under armored protection. The work of bulldozer and minesweeper is also carried out exclusively below the armored protection. The recovery vehicle is provided with a recovery device for the battlefield, which makes it possible to recover damaged vehicles under armored protection. The bridge launch vehicle is also designed for the arrangement and lifting of modular bridge parts. These vehicle concepts can also be combined with each other several times. The so-called universal support vehicle brings together the fundamental characteristics of the mine recovery, exploration and dredging variants. The bridge launching variant is shaped by means of a modification of the base structure in the construction of the roof, and by means of an arrangement of the crew space. An identical chassis serves as the basis for different vehicle variants. Such a concept is known from EP 0 974 510 A1.

From an exemplary embodiment with symbols, the invention is explained in more detail. It shows:

Fig. 1 Protection devices in the vehicle, viewed from the front left,

Fig. 2 Protection devices in the vehicle, viewed from the rear right,

Fig. 3 Protection devices in the vehicle, representation exploded.

Both Fig. 1 and Fig. 2 show a variant of universal support vehicle 1. In this variant it is designed as a minesweeper and excavator. The vehicle 1 is driven by a crew 2 in a crew cell 3. The closed crew cell 3 is decoupled in a chassis 4 by means of suitable elements.

The crew cell 3 has windows 31 made of shatterproof composite safety glass, as well as additional shields. In addition, the crew cell 3 has an outlet through the roof 33 and / or an outlet through the rear 34. As a suitable protection measure, the crew cell 3 has an air preparation facility 35 against atomic threats, biological and chemical, as well as an air conditioning of the crew room 36. In addition, the cell of the crew 3 is surrounded by a cover 5, which on the one hand includes the adaptive protection 51 and the roof protection 52. On the deck 5 is placed a dome of the commander 53 and a weapon station 54. Additionally, on the deck 5 or at the gun station 54 Nebel 55 rocket launching facilities can be adapted. Alternatively, a placement in the vehicle chassis is possible 4. With the Nebel 55 rocket launch facility, explosive grenades can also be fired.

The windows 31 can be protected by means of cover screens 37. In this case, the crew also has a sufficient view by means of the goniometric mirror 38.

Under the chassis 4 a mine protection plate is adapted in the region of the crew cell 3

41. The region of the rolling mechanism 42 can be covered at the front, at the rear and laterally by means of chain skirts 43.

Fig. 3 shows the cell of the raised crew 3 of the chassis 4 in an exploded representation. The cover 5, the adaptive protection 51 and the roof protection 52 can also be recognized.
