Definitions
- the present invention relates to a method and a system for destroying underwater objects, in particular underwater mines, using an autonomous consumable and submerged vehicle carrying an underwater destruction device.
- the field of the invention relates to mine warfare, an area to which all navies are confronted. Many of them are equipped with intervention means, dredging systems and hunting systems, which must evolve and renew themselves as the mine threat does; a mine threat against which, even recently, the most modern means of major navy have been put into service.
- a known system consists in locating an underwater mine, in dropping a locating means comprising at least two acoustic markers, or transponders, serving as fixed markers in the vicinity of the mine to be destroyed, to be relocated mine by determining its position relative to these benchmarks, and activating the destruction device using the position data.
- Underwater destruction means are carried by a surface or subsurface vehicle remotely controlled or not from a platform, and which for example tows a fish equipped with a side sonar, this vehicle being equipped with means for releasing the locating means.
- a relocation device is for example placed at the rear of the fish sailing in its wake.
- the the destruction device is preferably carried by the relocation device and may for example be a torpedo.
- This mine destruction system has the drawback of using costly relocation and destruction means capable of being destroyed at the same time as the mine. On the other hand, this system does not work effectively in the case of subsurface mines and in particular for ruddy mines.
- the invention aims to overcome the aforementioned drawbacks.
- the subject of the invention is a method of destroying underwater objects, consisting in guiding, from a mine hunter building, an unmanned vehicle carrying underwater destruction devices, characterized in that that it consists after launching the machine, in guiding the machine towards the mine by means of a sonar coupled to a tactical control station of the hunter ensuring the classification functions and the permanent control of the position of the 'machine in relation to the mine, to drop a locating means carried by the machine once the machine has arrived at a determined distance from the mine making it possible to perform a target designation function in cooperation with the machine and the hunter's tactical control station then, to communicate to the craft via the tactical control station, the navigation parameters necessary for its attack strategy depending on the type of mine encountered and its position referenced ée by the means of fixed location and, to destroy the mine according to the attack strategy acquired by the machine.
- One of the main advantages of the invention is to use a single type of autonomous remote-controlled vehicle, usable with total efficiency and security for the launching platform, which can be a surface building subsequently called a "hunter", this for underground mines, and for long or short ores, subsurfaces or not.
- the use of an acoustic marker carried by the machine makes it possible to ensure the objective designation function in permanent cooperation, with the efficient means of classification of the hunter, without the need for a sonar with high definition on the machine, the latter can therefore be consumable.
- FIG. 1 a block diagram of the main sequences of the method according to the invention
- FIGS. 2a and 2b the step prior to the launch sequence
- FIG. 3 three types of launching platform
- FIG. 4 an acoustic marker of a system for destroying underwater mines according to the invention
- FIGS. 5 and 6 a device destroying a system for destroying underwater mines according to the invention
- the stealth parameter does not intervene at this level because the target is supposed to have already been detected by the hunter.
- the pyrotechnic nature of the target can possibly only be recognized if the target has been identified and classified.
- a underground mine is a dense object, of various shape and volume, which can contain up to a ton of explosive.
- the mine rests on a bottom that can be of any kind, sandy, rocky, muddy, and its environment can be cloudy water or clear water (having nevertheless allowed its detection by hunting means).
- the nature of the hull is metallic (steel, aluminum) or composite.
- a short rope mine is a device that has the capacity to transport an explosive charge on its own.
- the mine consists of a fixed assembly forming an anchor on the bottom and a mobile assembly forming the projectile. These two sets are connected by means of a rope a few meters in length.
- a mine in open water there are two types of threat: a mine in open water, and a subsurface mine.
- the nature of the target is the same for both types: spherical or cylindrical float, having in its upper part a reserve of buoyancy and in its lower part an explosive charge.
- a mine in open water is a mine whose immersion is greater than 10 m, and for which the detection is not ambiguous, the anchor of the cane being located at any deep immersion.
- a subsurface mine is a target whose immersion is less than 10 m, and for which detection can be made difficult due to the proximity of the surface, which can make the approach difficult depending on the sea state. It is important to clearly define each type of target, because according to the types of target detected a particular attack strategy is adopted by the destructive device.
- the method according to the invention is described below according to two main scenarios depending on whether it is a bottom mine or a mooring mine. Each of these two scenarios is broken down into four identical main sequences 1 to 4 illustrated in FIG. 1: a launch sequence 1 of the destructive device, a rallying sequence 2 of the device near the mine, a sequence of 'wait 3 and an attack sequence 4.
- a step prior to the launching sequence 1, illustrated by FIGS. 2a and 2b, makes it possible to take a launching decision after detection, classification and possibly identification of a mine, mine placed on the bottom 5 FIG. 2a, or subsurface mine 6 Figure 2b, in particular a mooring mine.
- This launching decision is taken from hunting means 7 located for example in a hunter 8.
- the coordinates of the mine 5, 6 are known to the hunter 8 as well as the nature of the threat and certain data from environment. All these operations and data acquisitions are made from the hunting means 7 located on board the hunter 8.
- the hunter 8 To carry out its destruction mission, the hunter 8 remains in a classification situation on the mine 5, 6 for as long as possible. during the mission.
- FIG. 3 illustrates different types of launch platform, this platform possibly being the hunter 8 itself, a specialized surface building 10, or a helicopter 11.
- the vehicle 9 must therefore * be tracked.
- the hunter imager 8, not shown, cannot be used because it must remain directed towards the mine 5, 6. As and it is not omnidirectional, a device specific to guiding the destructive machine 9 is necessary. To benefit from great precision on the relative position of the hunter 8 with respect to the mine 5, 6, the guidance is carried out from the hunter 8.
- control station the functions of guidance, of trajectography, and more generally of communication between the destructive device 9 and the hunter 8 are implemented by a specific device called hereinafter "tactical control station" 12, coupled to the hunting means 7, and which will be designated subsequently by the single term control station tactical 12.
- the tactical control station 12 takes charge of the destructive device 9 as soon as it is launched. It manages the mission of the destructive device 9 automatically until its completion. The operator only intervenes to give the attack order; on the other hand, he has operational knowledge of the evolution of the mission via the tactical control station 12. Located on board the hunter 8 the tactical control post 12 benefits from all the knowledge of the hunting means 7: the coordinates of the target (classification classification), the environmental data (background, current, profile, bathimetry) as well that all the data relating to the mine in relation to its environment can contribute to the success of the mission (configuration of the bottom, result of identification, etc.).
- the tactical control station 12 guides and trajectographed the destructive machine 9 from the launch sequence 1 to the waiting sequence 3. It communicates the parameters of its mission to it, and in return receives a coded message, or "status ", from destructive device 9, the message containing its immersion and state data.
- the vehicle 9 although it is autonomous, is still tracked, subject to conditions of acoustic propagation of the medium.
- the tactical control station 12 is equipped, for example, with a base for transmission. reception of two hemispherical directivity acoustic transducers with a range of approximately 1 km. The base is mounted on the hull of the hunter 8 so as to measure the apparent deposit of the destructive machine 9. This base is not shown.
- the rallying sequence 2 of the vehicle 9 to the target 5, 6 can be carried out with the accuracy of the classification function of the sonar.
- the final approach after rally sequence 2 implies a precise knowledge of the goal, by learning the craft 9, autonomous, or assisted by the tactical control station 12 of the fighter 8, until the craft 9 has all the data that will allow it in sequence 4 to attack target 5, 6.
- Attack 4 must lead to the destruction of target 5, 6, which implies that all measures are taken so that the operational means located on board the hunter 8 are in a safe situation.
- a waiting sequence 3 is necessary and corresponds to a preparation sequence preceding the attack sequence 4.
- the hunter 8 is for example a surface building comprising an imager, a high-definition sonar classifier both coupled to a tactical control station 12 generally making it possible to communicate with the autonomous destructive machine 9 throughout the Duration of the mission.
- the hunter 8 located a target.
- an attack strategy is chosen by the tactical control station 12 according to the type of mine detected: bottom mine, long-haul, short-haul, subsurface.
- the tactical control station 12 acquires various parameters before launching 1 of the destructive device 9.
- the destructive device 9 carries a locating means
- the locating means illustrated in FIG. 4 constitutes an acoustic marker.
- the marker 13 consists of a part with positive buoyancy, for example a float 14 of spherical shape with an overall diameter of the order of 10 cm. A few centimeters from the bottom, the float 14 provides good contrast, the marker 13 must be heard throughout the upper hemisphere and at a short distance in the case of a bottom mine 5, and in a slightly more restricted solid angle , approximately 3 ⁇ / 2 radians, but at long distances, approximately 400 m in the case of a mooring mine 5.
- an emission transducer 15 is placed on the top of the float 14.
- the marker 13 is therefore provided with a dense anchor 16, of any shape in which are housed the bootable battery and the transmission electronics called hereinafter "transmitter”.
- the float 14 fitted with the transducer 15 is coupled to the anchor 16 by a rope 17 serving as a conductor between the transmitter 16 and the transducer 14. If damage to the propulsion and / or supply of the destructive vehicle 9 occurs during of the rally sequence 2 it falls on the bottom.
- the marker 13 has two main functions: a first objective designation relay function and a second function of "pinger" for locating the destructive vehicle 9 in the event of damage during rally sequence 2.
- the marker 13 is fixed on the destructive device 9 during the launching 1 and rallying 2 sequences to then be released, for example, by remote control, at the end of rallying sequence 2 near the mine 5.
- the marker 13 is autonomous, it is powered for example by a battery which can be started with sea water.
- the marker 13 is located in the field insonified by the hunter's sonar, in a known area with low uncertainties. Consequently, a modest reflection index of the order of -20 dB is sufficient to be seen by the classifier sonar of the hunter 8.
- FIGS. 5 and 6 An example of a destructive device 9 is shown in FIGS. 5 and 6.
- FIG. 5 represents the vehicle 9 at the start of the mission, during the launch sequence 1 and the start of the rallying sequence 2.
- FIG. 6 represents the vehicle at the end of the rallying sequence 2, the marker 13 released.
- the homologous elements are designated by the same references.
- the device 9 comprises a propulsion device 17 and a control surface 18 located in the tail of the device 9, an underwater ammunition compartment 19 located in the center of the device 9, the marker 13 and its ejection device 20 disposed at the head of the machine 9, and a set of seeker 21 H, 21 B and 21 F and sensors not shown, coupled to control electronics 22.
- a seeker is an assembly of acoustic transmitting and receiving transducers. Its role is divided into three main functions:
- the vertical sounder function generates a downward or upward emission relative to the destructive device and operates in detection of the first echo.
- the destructive device 9 thus has external markers (marker 13, mine 6) and its own means intended to accomplish its mission. It has a first external reference point reported on the bottom (the marker 13), and a second external reference point to be recognized (the mine 6). Its own resources must enable it to position itself absolutely in relation to these benchmarks at any time during its mission.
- These means are therefore composed of: - the three seeker, two vertical seeker 21H and 22H, respectively arranged on the craft 9 to cover the upper and lower hemispheres of the craft 9, and the frontal seeker, arranged at the head of the vehicle 9, and of the set of sensors distributed over the vehicle 9, altitude sensors, emission sensors, attitude sensors (heading, roll, pitch), as well as means indicating the speed of the 'machine 9 with respect to water, and calculation means.
- the calculation means on board the machine 9 enable it to calculate, from the guidance orders, its immersion (or altitude) its heading and its speed, which will then be translated by the machine 9 into commands from the steering bodies 19 and propulsion 18.
- the marker 13 is active, its emission is used by at least one of the seeker of the machine 9 to synchronize by acoustic coupling its internal clock which avoids implementing a reception function on the marker 13
- the tactical control station 12 measures the oblique distance of the destructive machine 9 and its apparent deposit.
- the destructive device 9 then transmits to the tactical control station 12 its immersion and its "status".
- the tactical control station 12 calculates the coordinates of the destructive device 9 and then transmits them to the device 9 as well as the guidance data and, the nature of the threat, which induces a determined strategy and default parameters, current information, as well as other specific parameters.
- the tactical control station 12 transmits the order to eject the marker 13 to the machine 9.
- the destructive device 9 In the case of a bottom mine 5, after dropping the marker 13 near the mine 5, in the sequence d waiting 3, the destructive device 9 is positioned at an altitude corresponding to the altitude of a determined waiting orbit. During this time, the tactical control station 12 transmits a set attitude to the destructive device 9 which positions itself in a waiting orbit around the marker 13. During the waiting sequence 3, the destructive device 9 "learns "the direction of the current, and the tactical control station 12 transmits to it the coordinates of a vector CM measured by the classifier sonar of the hunter 8, this vector CM giving the position of the mine 5 relative to the fixed frame of reference constituted by the acoustic marker 13 continuously emitting a signal recognizable by the device 9.
- the device 9 then leaves its waiting orbit and positions itself in orbit around the mine 5, it calculates the trajectory which allows it to arrive at the mine 5 facing the current, then transmits a "status" to the tactical control post 12.
- the machine 9 and the mine 5 are seen in the classifier field of the hunter 8.
- the dest reducer 9 is then entirely autonomous, and the hunter 8 moves away at a determined safety distance from the destruction zone.
- the machine 9 then reaches an attack altitude and begins a trajectory according to the trajectory calculated from data continuously updated by the tactical control station 12 of the fighter 8, these data corresponding to the azimuth data, distance from the mine 5 relative to marker 13, ie the vector CM, and altitude.
- the attack sequence 4 the machine 9 shoots "on the fly", vertically above the target 5.
- the seeker 9 pm covering the upper hemisphere of the machine 9 is triggered. It manages the reception of information from the marker 13 as well as the transmission of its seeker 21 H.
- the marker 13 and the machine 9 being synchronized, the detection and localization function of the marker 13 does not use any of the reception transducers which are the same as the transducers of the sounder which no longer needs to be operational because the localization of marker 13 implicitly performs the function of sounder.
- the machine 9 measures the coordinates of the marker 13 by telegoniometry; the range of the marker 13 is of the order of 400 m.
- the craft 9 In the detection and location function of a ruddy mine 6, the craft 9 is guided by the tactical control station 12 of the hunter 8 and navigates at an altitude lower than that of the ruddy mine 6 (subsurface or in full water).
- the 21H seeker broadcast covers the upper hemisphere of the craft at an angle of approximately 120 °.
- the machine 9 thus has the coordinates of the mine 6 relative to itself.
- FIGS. 7 to 23 schematically illustrate the different stages of the method according to the invention according to the two scenarios. For these different figures, the homologous elements are designated by the same references.
- FIGS. 7 and 8 illustrate the guidance towards the mine respectively for a bottom mine 5 and for a ruddy mine 6.
