Definitions

  • the invention relates to a method in which the generation of a liquid mist is used in order to minimize the effect of a detonation in the watercraft.
  • the disadvantage is that when a liquid mist is generated, damage is practically always caused, in particular electronic components are regularly affected. In addition, the extinguishing liquid can of course also have an influence on the ability to swim.
  • a fire extinguishing device and a fire extinguishing method are known from WO 2003/061769 A1.
  • the object of the invention is to create a method that enables a reduction in detonation damage through the formation of a liquid mist and at the same time minimizes the collateral damage caused by the liquid. It is precisely the object of the invention not to compete with short-range defense systems or countermeasures, but rather to minimize damage after their failure and thus damage caused by the impact of a missile. This object is achieved by the method having the features specified in claim 1. Advantageous further developments result from the subclaims, the following description and the drawings.
  • the method according to the invention for minimizing damage to a watercraft has the following steps: a) Providing the watercraft and a database, the watercraft having rooms R n , the database containing time information t R for at least one room Ri, the time information t R , the time required to generate a liquid mist in the space Ri to which this time information t R is assigned, b) detection and location of a threat in the form of a flight object, c) determination of the movement of the flight object, d ) Determining the collision location between the flight object and the watercraft, e) Determining the space R, the watercraft that is adjacent to the collision location, f) Determining the time information t R , for this space R, from the database, g) Determining the point in time to, at which the flight object has reached a position at which the remaining flight time to the collision location corresponds to the time information t R , h) At the time point to or at time to - Ato start of the generation of a liquid mis
  • Watercraft within the meaning of the invention are in particular military watercraft, in particular military surface vehicles, for example and preferably, cruisers, destroyers, frigates, corvettes, task force providers, minesweepers, minehunters, aircraft carriers, helicopter carriers, amphibious warships, landing ships, battleships.
  • military surface vehicles for example and preferably, cruisers, destroyers, frigates, corvettes, task force providers, minesweepers, minehunters, aircraft carriers, helicopter carriers, amphibious warships, landing ships, battleships.
  • the watercraft has n spaces R n , where n is a natural number.
  • a certain room is created by numbering the rooms.
  • a watercraft has 10 rooms, so there are rooms Ri, R2, R3, R 4 , Rs, R6, R7, Rs, R 9 and R 10.
  • Ri is the i-th room of the watercraft ⁇ , where i is a natural number between 1 and n.
  • Spaces within the meaning of the invention are spaces inside the watercraft, for example the bridge, mess, galley, quarters, corridors, engine rooms and the like. Spaces are thus interior spaces of the watercraft, and these, such as a hangar, for example, can also have a large opening to the outside.
  • a room usually has walls, a floor and a ceiling. Rooms usually have a door to enter, and there are also rooms in a watercraft that can only be entered, for example, through an opening in the ceiling, for example a battery room. Space is therefore to be understood in the sense of room.
  • the time information ⁇ RI , t R 2, ... t Rn -i, t Rn is stored in the database for the spaces Ri, R2, ... R n -i, R n.
  • the time t R for space R results from the time required to generate a liquid mist in space R. This time depends, for example, on the size of the room and, for example, the number of sprinkler systems that can be used to generate the liquid mist.
  • time information t R does not have to be stored for every room R of the watercraft.
  • rooms can be excluded that are inside or permanently below the waterline if a missile impact is considered unrealistic here.
  • rooms could be excluded in which no liquid mist can and should not be generated, for example IT rooms that have an automatic extinguishing device using CO2.
  • At least the rooms R, which have a device for generating a liquid mist, are thus advantageously recorded in the database.
  • at least the spaces R 1 are recorded which are arranged on the outside of the watercraft in the area above the water.
  • Flying objects encompass all possible threats from warheads, grenades, cruise missiles, missiles to airplanes. These can fly purely ballistically, actively fly or ballistically fly with control options, whereby the control options can be active or passive.
  • the rooms Ri, R 2 , ... Rn- 1 , Rn can also be combined in functional groups or coherent locations and controlled together.
  • the ammunition stores, ship sections or external rooms on the port or starboard side can form common groups. It is essential to form the groups of rooms in such a way that the spread of the damage to the ship is slowed down and the damage is reduced.
  • the structural design of the ship can be the criteria for the formation of space groups.
  • Another advantage of the invention is that this additional protection cannot be seen by an opponent.
  • Practically all larger military watercraft have both a radar system and a sprinkler system, which is suitable for generating a liquid mist. However, these are usually integrated into different and strictly separate ship systems. While the Combat Management System is connected to the radar, an integrated platform management system controls the fire fighting equipment.
  • Such a military watercraft can easily be equipped with a control system for carrying out the method according to the invention, which, however, in contrast to thick armor, cannot be seen by an enemy from the outside, so that the weakened detonation effect of a warhead cannot be foreseen by the enemy in the field.
  • step h a liquid mist is thus generated in the interior of at least one room and thus in the interior of the watercraft.
  • This is disadvantageous in principle for two reasons. On the one hand, extinguishing water that is not required can cause damage, from electronic devices to paper documents to food or clothing. On the other hand, however, water also gets into the interior of the watercraft, which is usually just avoided in terms of buoyancy.
  • the essence of the invention is now to accept these disadvantages with approval in order to minimize the effect of the detonation of a warhead. Here it goes not, or at least not primarily, to fight a potentially emerging fire before it arises, but rather to weaken the spread of a pressure wave or a plasma lance generated by a warhead and thus already reduce the primary damage caused by a warhead.
  • Steps b) and c) are preferably carried out by means of radar, optical sensors and / or acoustic sensors. Steps b) and c) are particularly preferably carried out by means of radar.
  • step c) The determination of the movement in step c) can take place either on the basis of two measurements spaced apart in time and the measured position difference. However, it can also take place directly, for example by means of frequency shifting (Doppler effect).
  • steps b) and c) are carried out, in particular in a convoy, by a second watercraft, for example and in particular an escort ship, for example a destroyer, and the data determined are then transferred to the first watercraft, for example a task force provider who do not have or at least not a comparable radar system themselves. If necessary, step e) can also be carried out on the second watercraft.
  • step h) a liquid mist is not only generated in room R, but that, in the event of an acute threat, this is optionally carried out in neighboring rooms, for example in rooms R M and R M.
  • steps f) to h) are preferably carried out for each room R M , R, and R M. This results in a point in time to.RM for the space R M, a point in time to.Ri for the space R and a point in time to, Ri + i for the space R M.
  • step b further measures can be taken to prevent the missile from impacting, for example an attempt can be made with close-range defense systems to destroy the missile before it reaches the watercraft. It is also possible, with the aid of countermeasures, to attempt to deceive the target search function of the missile and thus to guide the missile away from the watercraft. These measures can also be carried out in parallel to step h). Although water damage has already occurred in the rooms concerned, avoiding the impact is always the best option. The method according to the invention thus represents an additional and downstream line of defense to the conventional systems of close-range defense and countermeasures.
  • steps c) to e) are repeated continuously in order to detect changes in movement.
  • steps c) to e) are repeated continuously in order to detect changes in movement.
  • steps c) to e) are repeated continuously in order to detect changes in movement.
  • the method according to the invention is then preferably terminated as quickly as possible in order to avoid unnecessary water damage.
  • the generation of the Liquid mist continued for a period at in.
  • fire monitoring is carried out in room R to determine whether the impact triggered a fire in room R.
  • the generation of the liquid mist is continued beyond the point in time t in + At in.
  • the generation of the liquid mist is stopped at time t in + At in.
  • steps b) and c) are carried out by a combat management system.
  • the combat management system on a military watercraft includes the controls, for example, of the sensors for detecting the threat situation, for example the radar, as well as the control of the effectors, for example guns, missiles or close-range defense systems.
  • the combat Management System is therefore specially shielded for security reasons in order to prevent any unwanted external intervention.
  • Steps d) to h) are carried out by a control system.
  • the control system can in particular be designed as an independent system in order to only carry out this part of the method according to the invention outside of the other ship systems, which enables optimal integration into the security architecture and optimal retrofitting.
  • the combat management system and the control system are only connected via a unidirectional connection for the transfer of data from the combat management system to the control system.
  • Unidirectional connections are established, for example, via so-called data diodes and ensure that, for example, no malicious software can be transferred from the control system to the Combat Management System and thus the security of the system is fully guaranteed.
  • a liquid mist is generated in step h) by a control system in that the control system transmits a fire message to the fire fighting system.
  • Flier initiates the fire fighting system fire fighting measures, which lead to the generation of the liquid mist.
  • the sprinkler system in room R is activated.
  • a non-conductive fluid for example CF 3 CF 2 C (0) CF ( CF 3) 2
  • the watercraft has a supply of non-conductive fluid in order to enable the liquid mist to be generated at least from to to t in + At. If the non-conductive fluid is used up, further fire fighting can also be carried out with fresh water or sea water. Damage to electronics, for example, is then accepted, since an arbitrarily large supply of non-conductive fluid does not make sense and fire fighting has priority over damage caused by extinguishing water.
  • course data and speed data of the watercraft are used to determine the collision location in step d).
  • An exact prediction of the future whereabouts of the watercraft is possible due to the adjacent course. While this information for the flight object can only be predicted from the past, this additional information is available to the watercraft for its own future, which increases the probability of prediction.
  • the invention relates to a military watercraft which is designed to carry out the method according to the invention.
  • a watercraft 10 is shown in a highly schematic manner.
  • the watercraft 10 has a radar 40 which is controlled via a combat management system 50.
  • the combat management system 50 is connected to a control system 30 via a data diode 60. Via the data diode 60, the combat management system 50 transmits information about approaching flight objects 80 to the control system 30.
  • the control system 30 has a database in which the time information t R is stored for all rooms R of the watercraft 10. If the control system 30 identifies a room R ,, which is threatened by an approaching flight object 80 and is to be protected by a liquid mist, the control system 30 transmits a fictitious fire alarm for the room R to the integrated platform management system 70 at time to.
  • the integrated platform management system 70 has control over a fire-fighting system, which also includes the fire-fighting means B in the rooms R.
  • a fire-fighting system which also includes the fire-fighting means B in the rooms R.
  • the integrated platform management system 70 activates the fire fighting means B in the affected room R.
  • a liquid mist is formed in the space R at precisely the moment t in at which the flying object 80 hits the space R, and the detonation effect is minimized.
  • FIG. 2 shows a first scenario with a purely ballistic flying object 80.
  • the flying object 80 is detected and the direction and speed are determined. This point in time tü is shown in FIG. 2a. Since the watercraft 10 is not at rest, however, it is moving, as can be seen in the course of FIG. 2a via FIG. 2b to FIG. 2c. Since the control system 20 receives the information on this intrinsic movement from the integrated platform management system 70, the control system can already recognize the room Rs as the point of impact at the point in time tü. At time to shown in FIG. 2b, the remaining flight time of the flying object 80 is equal to the time which is required to generate a liquid mist in space Rs, which is why the control system initiates this at this time. FIG. 2c then shows the impact at the point in time t in, at which the liquid mist is completely formed in the space Rs.

  • the flight object 80 is detected at time tu in FIG. 3, the direction and speed are determined and the impact for space Rs is predicted.
  • the flying object 80 changes once its flight direction slightly, which is detected by the radar 30 between tü and to. This changes the impact prognosis for space R3 and, at time to, which is shown in FIG. 3b, the liquid mist is generated in space R3.
