Description

Le secteur technique de la présente invention est celui des dispositifs de chargement de munitions pour véhicules militaires, et plus particulièrement des dispositifs permettant de diminuer la vulnérabilité aux agressions des enceintes de stockage de munitions.The technical sector of the present invention is that of ammunition loading devices for military vehicles, and more particularly devices to reduce the vulnerability to attack of ammunition storage enclosures.

Dans le domaine technique du stockage des munitions, il est bien connu qu'une explosion survenant dans une enceinte de stockage de munitions est particulièrement dévastatrice. Il est donc souhaitable, en cas d'agression d'éviter la détonation d'une munition ainsi que la propagation du phénomène aux munitions voisines. C'est notamment le cas dans les véhicules militaires de combat, où l'agression par un projectile à charge creuse constitue une des principales menaces, pouvant provoquer une détonation en masse au niveau du caisson de chargement automatique des munitions. Il est alors particulièrement souhaitable d'éviter une telle détonation qui provoquerait la destruction totale du véhicule.In the technical field of ammunition storage, it is well known that an explosion occurring in an ammunition storage chamber is particularly devastating. It is therefore desirable, in case of aggression, to avoid the detonation of a munition and the propagation of the phenomenon to neighboring munitions. This is particularly the case in military combat vehicles, where aggression by a hollow charge projectile is one of the main threats, which can cause a mass detonation at the level of the ammunition automatic loading box. It is then particularly desirable to avoid such a detonation which would cause the total destruction of the vehicle.

Actuellement, les soutes à munitions d'un char sont protégées par des épaisseurs de pré-blindage localisées de façon à minimiser les probabilités d'atteinte par une menace (projectile perforant ou à charge creuse, éclat lourd, ...). Bien que les probabilités d'atteinte soient réduites, elles demeurent réelles et les effets dus à l'agression par une menace demeurent dévastateurs.Currently, tank ammunition bunkers are protected by localized pre-armor thicknesses in order to minimize the probability of attack by a threat (piercing or hollow-fired projectile, heavy flare, etc.). Although the probabilities of attack are reduced, they remain real and the effects of aggression by a threat remain devastating.

Le but de la présente invention est de fournir un dispositif de chargement qui permette de déplacer les munitions dans une enceinte de stockage en fonction d'une menace réelle ou potentielle afin les diminuer les effets de l'agression de l'enceinte de stockage par la menace.The object of the present invention is to provide a loading device that makes it possible to move the ammunition in a storage enclosure according to a real or potential threat in order to reduce the effects of the aggression of the storage enclosure by the threat.

L'invention a donc pour objet un dispositif de chargement des munitions dans un véhicule militaire comportant une enceinte de stockage des munitions et un convoyeur permettant le déplacement des munitions dans l'enceinte de stockage couplé à des moyens permettant le chargement et/ou le déchargement des munitions dans la chambre d'une arme, caractérisé en ce qu'il comporte un moyen de contrôle de vulnérabilité qui permet de déterminer le positionnement des munitions dans l'enceinte à adopter en fonctions des risques d'agression de l'enceinte, moyen qui assure la commande automatique du convoyeur et/ou des moyens de chargement/déchargement en fonction des dits risques.The invention therefore relates to a munitions loading device in a military vehicle comprising an ammunition storage chamber and a conveyor for moving ammunition in the storage enclosure coupled to means for loading and / or unloading. ammunition in the chamber of a weapon, characterized in that it comprises a vulnerability control means which makes it possible to determine the positioning of the ammunition in the enclosure to adopt in terms of risks of aggression of the enclosure, means that ensures the automatic control of the conveyor and / or means of loading / unloading according to said risks.

Selon une caractéristique de l'invention, le moyen de contrôle de la vulnérabilité est relié à un système d'aide au commandement qui comporte des moyens de liaison avec à des moyens de détection et/ou d'évaluation d'une menace réelle ou potentielle afin de modifier la disposition des munitions en fonction de la menace détectée ou évaluée.According to one characteristic of the invention, the vulnerability control means is connected to a command-aiding system which comprises means of connection with means for detecting and / or evaluating a real or potential threat. to change the disposition of the ammunition based on the threat detected or assessed.

L'invention concerne également un procédé de commande d'un dispositif de chargement de munitions d'un véhicule militaire comprenant un convoyeur et une enceinte de stockage des munitions et des moyens de chargement et/ou déchargement des munitions, caractérisé en ce qu'on déplace et/ou sélectionne les munitions de façon à les séparer d'une distance d'espacement, afin de diminuer les risques de propagation en cas d'explosion d'une munition.The invention also relates to a method for controlling an ammunition loading device of a military vehicle comprising a conveyor and an ammunition storage chamber and means for loading and / or unloading the ammunition, characterized in that moves and / or selects the ammunition so as to separate them from a spacing distance, in order to reduce the risks of propagation in the event of an ammunition explosion.

Selon une caractéristique de l'invention, on déplace et/ou sélectionne les munitions par groupes d'au moins deux munitions verticalement alignées, en séparant chaque groupe d'une distance d'espacement, afin de diminuer les risques de propagation en cas d'explosion d'une munition.According to one characteristic of the invention, the ammunition is moved and / or selected in groups of at least two vertically aligned ammunition, separating each group by a spacing distance, in order to reduce the risks of propagation in the event of explosion of a munition.

L'invention concerne également un procédé de commande d'un dispositif de chargement de munitions d'un véhicule militaire comprenant un convoyeur et une enceinte de stockage des munitions, caractérisé en ce qu'on détecte une menace (10;11), on détermine la zone de l'enceinte susceptible d'être atteinte par la menace et on commande le convoyeur pour déplacer les munitions dans l'enceinte de façon à les écarter de la zone susceptible d'être atteinte par la menace.The invention also relates to a method for controlling an ammunition loading device of a military vehicle comprising a conveyor and an ammunition storage chamber, characterized in that a threat (10; the area of the enclosure likely to be affected by the threat and the conveyor is ordered to move the ammunition in the enclosure so as to remove them from the area likely to be affected by the threat.

L'invention concerne également un procédé de commande d'un dispositif de chargement de munitions appliqué à un véhicule militaire intégré dans une formation, caractérisée en ce qu'on commande le convoyeur du véhicule de façon à disposer les munitions vers l'intérieur de la formation.The invention also relates to a method for controlling an ammunition loading device applied to a military vehicle integrated into a formation, characterized in that the conveyor of the vehicle is controlled so as to dispose the ammunition towards the inside of the vehicle. training.

Selon une caractéristique de l'invention, un calculateur détermine des priorités de positionnement des munitions et favorise un positionnement des munitions adapté à un rechargement rapide de l'arme lorsque le véhicule adopte une phase de tir.According to one characteristic of the invention, a computer determines priorities for positioning the ammunition and promotes ammunition positioning adapted to a rapid reloading of the weapon when the vehicle adopts a shooting phase.

Un tout premier avantage du dispositif selon l'invention réside dans le fait qu'il permet de diminuer le risque de détonation des munitions lors de l'agression de leur enceinte de stockage.A first advantage of the device according to the invention lies in the fact that it reduces the risk of detonation of ammunition during the aggression of their storage enclosure.

Le risque peut être diminué par l'adoption d'une disposition relative des munitions permettant de réduire les risques de détonation en masse.The risk can be reduced by adopting a relative ammunition provision to reduce the risk of mass detonation.

Le risque peut également être diminué par l'adoption d'une disposition globale des munitions permettant de réduire les risque d'atteinte des munitions par une menace.The risk can also be reduced by adopting a global ammunition provision that reduces the threat of ammunition by a threat.

Un autre avantage du dispositif réside dans le fait que ce dernier peut être utilisé en complément d'autres protections d'une enceinte de stockage.Another advantage of the device lies in the fact that the latter can be used in addition to other protections of a storage enclosure.

D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels :

  • la figure 1 illustre schématiquement le dispositif selon l'invention,
  • les figures 2a et 2b sont des exemples d'utilisation du dispositif face à des menaces potentielles ou réelles, et
  • les figures 3a et 3b illustrent des exemples de disposition des munitions dans leur enceinte de stockage.
Other characteristics, details and advantages of the invention will emerge more clearly from the description given below as an indication in relation to drawings in which:
  • FIG. 1 schematically illustrates the device according to the invention,
  • FIGS. 2a and 2b are examples of use of the device in the face of potential or real threats, and
  • FIGS. 3a and 3b illustrate examples of disposition of the ammunition in their storage enclosure.

La figure 1 représente schématiquement un dispositif de commande de la disposition des munitions selon l'invention. Dans ce dispositif, des munitions 9 sont stockées dans une enceinte 1 de stockage et un convoyeur 2 permet le déplacement des munitions dans l'enceinte de stockage.Figure 1 schematically shows a device for controlling the disposition of ammunition according to the invention. In this device, ammunition 9 is stored in a storage chamber 1 and a conveyor 2 enables the ammunition to be moved in the storage enclosure.

Un tel convoyeur est bien connu et décrit par le brevet FR2664966 . Il comporte une chaîne sans fin de godets portant chacun une munition.Such a conveyor is well known and described by the patent FR2664966 . It has an endless chain of buckets each carrying a munition.

D'une façon classique ce déplacement permet d'amener les munitions au voisinage de la chambre d'une arme (non représentée) afin de permettre le chargement de la munition.In a conventional manner this movement makes it possible to bring the ammunition close to the chamber of a weapon (not shown) in order to allow the loading of the ammunition.

Le convoyeur est associé à des moyens (non représentés) permettant le chargement et/ou le déchargement des munitions dans la chambre de l'arme (par exemple un moyen de refoulement). Conformément à l'invention un moyen de contrôle de vulnérabilité 3, qui est constitué par un calculateur 3 incorporant un logiciel approprié, est relié au convoyeur 2 ainsi qu'à un pupitre 6 d'approvisionnement, à une conduite de tir 4 et à un système 5 d'aide au commandement. Les utilisations d'une conduite de tir et d'un pupitre d'approvisionnement en relation avec un convoyeur sont déjà connues et n'ont pas besoin d'être spécifiquement décrits. On notera cependant que le pupitre 6 d'approvisionnement permet préalablement à une mission de remplir l'enceinte 1 de stockage du véhicule en déterminant le nombre et le type de munitions en fonction de la mission à réaliser et de mémoriser le positionnement de chaque munition. Le tireur détermine à l'aide de la conduite de tir 4 le type de munition à charger dans l'arme en fonction de la cible à atteindre. La conduite de tir 4 commande ensuite directement le chargement automatique de l'arme en fonction de la disposition des différentes munitions mémorisée lors du chargement de l'enceinte et afin de permettre des séquences de tir les plus rapides possible.The conveyor is associated with means (not shown) allowing the loading and / or unloading of ammunition in the chamber of the weapon (for example a means of repression). In accordance with the invention, a vulnerability control means 3, which is constituted by a computer 3 incorporating appropriate software, is connected to the conveyor 2 as well as to a supply desk 6, to a firing line 4 and to a command assistance system. The uses of a firing line and a supply desk in connection with a conveyor are already known and do not need to be specifically described. Note however that the console 6 supply allows prior to a mission to fill the chamber 1 storage of the vehicle by determining the number and type of ammunition depending on the mission to achieve and memorize the positioning of each munition. The shooter determines using the firing line 4 the type of ammunition to be loaded into the weapon according to the target to be reached. The fire control 4 then directly controls the automatic loading of the weapon according to the disposition of the various ammunition stored during the loading of the enclosure and to allow shooting sequences as fast as possible.

Conformément à l'invention le calculateur 3 incorpore des moyens logiciels spécifiques assurant le contrôle de la vulnérabilité des munitions 9 dans l'enceinte 1. Ce moyen permet de déterminer le positionnement des munitions 9 dans l'enceinte 1 qui doit être adopté en fonction des risques d'agression de l'enceinte. Dans le mode de réalisation qui est ici décrit, le dispositif selon l'invention est relié à des moyens (non représentés) de détection et/ou d'évaluation d'une menace réelle ou potentielle par des moyens 12 de liaison permettant l'échange de données. Ainsi le moyen 3 peut assurer la commande automatique du convoyeur 2 en fonction des risques. Il commandera une modification de la disposition des munitions en fonction de la menace ainsi détectée ou évaluée.According to the invention the computer 3 incorporates specific software means ensuring the control of the vulnerability of the ammunition 9 in the chamber 1. This means makes it possible to determine the positioning of the ammunition 9 in the chamber 1 to be adopted according to the risks of aggression of the enclosure. In the embodiment which is described here, the device according to the invention is connected to means (not shown) for detecting and / or evaluating a real or potential threat by connection means 12 enabling the exchange of data. Thus the means 3 can ensure the automatic control of the conveyor 2 according to the risks. He will order a modification of the disposition of the ammunition according to the threat thus detected or evaluated.

Les moyens de détection d'une menace sont des moyens permettant la détection d'une menace réelle (menace identifiée) ou potentielle (zones "sensibles", détection de véhicules non identifiés, ...). Ces moyens de détections peuvent être portés par le véhicule ou déportés. Les moyens 12 de liaison représentés sur cette figure sont des moyens du type antenne de communication par ondes radio afin de permettre la communication entre le moyen 3 de contrôle de vulnérabilité (via le système 5 d'aide au commandement) et des moyens de détection et/ou d'évaluation déportés, par exemple un satellite, un poste de commandement, un drone, ou tout autre moyen susceptible de fournir des informations sur une menace réelle ou potentielle. Avantageusement, lorsque plusieurs véhiculés se déplacent en formation, les moyens 12 de liaison permettent également l'échange d'informations entre les véhicules afin de connaître le positionnement du véhicule dans la formation et de bénéficier des informations issues des moyens de détection équipant les autres véhicules. Certains moyens d'évaluation de la menace pourront être intégrés au système 5 d'aide au commandement ou au moyen de contrôle de vulnérabilité 3, par exemple un logiciel de cartographie permettant de connaître les zones ennemies, un logiciel de reconnaissance ami/ennemi ou un dispositif d'identification de projectiles.The means of detecting a threat are means for detecting a real threat (threat identified) or potential ("sensitive" areas, detection of unidentified vehicles, etc.). These detection means can be carried by the vehicle or deportees. The linkage means 12 shown in this figure are means of the radio wave communication antenna type in order to allow the communication between the vulnerability control means 3 (via the command assistance system) and the detection and detection means. / or deported evaluation, for example a satellite, a command post, a drone, or any other means likely to provide information on a real or potential threat. Advantageously, when several vehicles move in formation, the connection means 12 also allow the exchange of information between the vehicles to know the positioning of the vehicle in the formation and to benefit from the information from the detection means equipping the other vehicles . Some means of threat assessment may be integrated into the Command Support System or Vulnerability Control System 3, for example, mapping software to identify enemy areas, friend / foe reconnaissance software, or projectile identification device.

La figure 2a illustre un exemple d'utilisation du dispositif selon l'invention en cas de détection de menaces réelles. Dans cet exemple, on a détecté plusieurs sources de menaces (non représentées), par exemple des véhicules ou bâtiments ennemis, des missiles air-sol, susceptibles de générer des menaces réelles (tirs de projectiles, missiles) 10a, 10b et 10c pour une formation 8 de véhicules 7a, 7b et 7c. Sur chaque véhicule 7, le moyen 3 de contrôle de vulnérabilité détermine alors la zone de l'enceinte 1 susceptible d'être atteinte par la menace et commande le convoyeur afin de déplacer automatiquement les munitions 9 dans l'enceinte 1 de façon à les écarter de la zone susceptible d'être atteinte par la menace.FIG. 2a illustrates an example of use of the device according to the invention in the event of detection of real threats. In this example, several sources of threats (not shown) have been detected, for example enemy vehicles or buildings, air-to-surface missiles, capable of generating real threats (projectiles firing, missiles) 10a, 10b and 10c for a formation 8 of vehicles 7a, 7b and 7c. On each vehicle 7, the vulnerability control means 3 then determines the zone of the enclosure 1 likely to be reached by the threat and commands the conveyor to automatically move the ammunition 9 into the chamber 1 so as to move them away. the area likely to be affected by the threat.

On remarquera que lorsque des véhicules 7 se déplacent en formation les zones les plus vulnérables des enceintes 1 se situent vers l'extérieur de la formation. Un procédé de commande du dispositif de chargement avantageux consiste donc à disposer, par défaut, les munitions vers l'intérieur de la formation. A cet effet on pourra avantageusement indiquer au système d'aide au commandement la disposition spatiale de la formation et la situation de chaque véhicule dans cette dernière (par exemple par saisie manuelle, par des moyens de détection ou par communication entre eux des systèmes d'aide au commandement équipant chaque véhicule).It will be noted that when vehicles 7 move in formation the most vulnerable zones of the enclosures 1 are located towards the outside of the formation. A method of Advantageous loading device control therefore consists in arranging, by default, ammunition towards the inside of the formation. For this purpose it will advantageously be possible to indicate to the command-aiding system the spatial arrangement of the formation and the situation of each vehicle in the latter (for example by manual entry, by means of detection or by communication between them of the control systems. command support for each vehicle).

La figure 2b illustre un exemple d'utilisation du dispositif selon l'invention en cas d'évaluation de menaces potentielles. Dans cet exemple, on a détecté (par exemple au moyen d'un drone ou d'un satellite) une zone 11 susceptible d'abriter des menaces pour une formation 8 de véhicules. Le moyen 3 de contrôle de vulnérabilité détermine alors la zone de l'enceinte 1 susceptible d'être atteinte par la menace et commande le convoyeur afin de déplacer les munitions 9 dans l'enceinte 1 en fonction de la zone susceptible d'être atteinte par la menace.FIG. 2b illustrates an example of use of the device according to the invention in the event of evaluation of potential threats. In this example, there has been detected (for example by means of a drone or a satellite) an area 11 capable of harboring threats for a formation of vehicles. The vulnerability control means 3 then determines the zone of the chamber 1 likely to be reached by the threat and commands the conveyor to move the ammunition 9 in the chamber 1 according to the area likely to be reached by the threat.

Suivant un autre mode de réalisation de l'invention, et indépendamment de toute évaluation d'une menace, l'invention permet également de diminuer la vulnérabilité du chargement en commandant des déplacements de munitions susceptibles de diminuer cette vulnérabilité.According to another embodiment of the invention, and independently of any threat assessment, the invention also makes it possible to reduce the vulnerability of the load by controlling displacements of ammunition capable of reducing this vulnerability.

Suivant ce mode de réalisation on commandera à l'aide du dispositif le déplacement et/ou la sélection des munitions de façon à les séparer dans la mesure du possible les unes des autres d'une distance (d) d'espacement, afin de diminuer les risques de propagation en cas d'explosion d'une munition.According to this embodiment, the device will be used to move and / or select the munitions so as to separate them as far as possible from one another by a distance (d) of spacing, in order to decrease the risks of propagation in the event of an ammunition explosion.

Le calculateur 3 a mémorisé lors des phases de chargement de l'enceinte 1 la position des différentes munitions. Le tir sera alors réalisé par prélèvements successifs des munitions en laissant des intervalles entre chaque munition.The computer 3 has memorized during the loading phases of the chamber 1 the position of the various ammunition. The shot will then be made by successive samples of ammunition leaving intervals between each ammunition.

On pourra par exemple prélever une munition sur deux. Il en résultera des intervalles entre chaque munition qui diminueront la vulnérabilité de l'enceinte 1.For example, one out of two ammunition can be taken. This will result in intervals between each ammunition which will decrease the vulnerability of the enclosure 1.

Afin d'accélérer le tir, ce prélèvement d'une munition sur deux pourra être inhibé lorsque l'on souhaite pratiquer un tir redoublé (deux tirs consécutifs).In order to accelerate the firing, this sampling of one ammo out of two can be inhibited when one wishes to practice a redoubled shot (two consecutive shots).

Pour faciliter la mise en oeuvre de ce mode de réalisation de l'invention on pourra dès la phase initiale de chargement de l'enceinte 1 ne pas remplir totalement l'enceinte mais maintenir un espace entre chaque munition.To facilitate the implementation of this embodiment of the invention can be from the initial phase of loading of the enclosure 1 do not completely fill the enclosure but maintain a space between each munition.

Les figures 3a et 3b représentent ainsi schématiquement des modes de répartition des munitions dans leur enceinte de stockage.FIGS. 3a and 3b thus schematically represent modes of distribution of the ammunition in their storage enclosure.

Dans un premier mode de réalisation, illustré par la figure 3a, on dispose les munitions 9 par groupes de plusieurs munitions verticalement alignées, en séparant les groupes d'une distance d'espacement d, afin de diminuer les risques de propagation en cas d'explosion d'une munition. La distance d sera définie en fonction des caractéristiques de la munition (dimensions, charge, ...) et de l'enceinte de stockage (dimensions de l'enceinte et des emplacements des munitions, dispositif de déconfinement).In a first embodiment, illustrated in FIG. 3a, ammunition 9 is arranged in groups of several vertically aligned ammunition, separating the groups by a spacing distance d, in order to reduce the risks of propagation in the event of explosion of a munition. The distance d will be defined according to the characteristics of the munition (dimensions, load, ...) and the storage enclosure (dimensions of the enclosure and the ammunition locations, deconfinement device).

Dans un second mode de réalisation, illustré par la figure 3b, on dispose les munitions 9 en les scindant en deux groupes disposés de part et d'autre de l'enceinte.In a second embodiment, illustrated in FIG. 3b, munitions 9 are disposed by splitting them into two groups arranged on either side of the enclosure.

Le fonctionnement est le suivant. Lorsque le véhicule est en phase de tir, il est essentiel que le tir de la munition et le rechargement de l'arme soient réalisés le plus rapidement possible, les munitions 9 doivent donc être disposées à proximité de la chambre de chargement. Le calculateur ou moyen de contrôle 3 détermine des priorités d'ordres de positionnement des munitions à relayer vers le convoyeur 2, qui effectue alors le positionnement optimal tel qu'il est déterminé par le moyen de contrôle 3. Lorsque le véhicule n'est plus en phase de tir, le calculateur 3 commande le positionnement des munitions en fonction des contraintes de vulnérabilité. En cas de détection ou d'estimation d'une menace réelle ou potentielle transmise au moyen de contrôle 3 via le système 5 d'aide au commandement, le moyen de contrôle 3 détermine la pertinence de la menace et la zone de l'enceinte 1 susceptible d'être atteinte par la menace. En fonction de ces estimations, il détermine le positionnement des munitions 9 dans l'enceinte 1 à adopter et commande au convoyeur 2 le déplacement et le positionnement des munitions.The operation is as follows. When the vehicle is in the shooting phase, it is essential that the firing of the ammunition and the reloading of the weapon be carried out as quickly as possible, the ammunition 9 must therefore be placed near the loading chamber. The computer or control means 3 determines priorities of positioning orders of the ammunition to be relayed to the conveyor 2, which then performs the optimal positioning as determined by the control means 3. When the vehicle is no longer in the firing phase, the computer 3 controls the positioning of the ammunition according to the vulnerability constraints. In case of detection or estimation of a real or potential threat transmitted to the control means 3 via the command assistance system 5, the control means 3 determines the relevance of the threat and the zone of the enclosure 1 likely to be affected by the threat. Based on these estimates, it determines the positioning of the ammunition 9 in the enclosure 1 to adopt and orders the conveyor 2 displacement and positioning ammunition.

En l'absence de détection ou d'estimation de menace, il est essentiel de disposer les munitions de sorte à diminuer les risques de propagation en cas d'explosion d'une munition. A cet effet, on dispose les munitions 9 (individuellement ou par groupes d'au moins deux munitions verticalement alignées) en les séparant d'une distance d d'espacement.In the absence of threat detection or estimation, it is essential to dispose of the munitions so as to reduce the risk of propagation in the event of a munition explosion. For this purpose, ammunition 9 (individually or in groups of at least two vertically aligned ammunition) is placed at a spacing distance d apart.

Avantageusement, toute instruction à destination du convoyeur 2 est relayée par le calculateur 3, et la liaison entre le convoyeur et le calculateur est une liaison à double sens permettant au convoyeur d'envoyer au calculateur des informations relatives au positionnement des munitions, ce qui permet au calculateur 3 de connaître la disposition des munitions dans l'enceinte 1.Advantageously, any instruction to the conveyor 2 is relayed by the computer 3, and the link between the conveyor and the computer is a two-way link allowing the conveyor to send the computer information relating to the positioning of the ammunition, which allows the calculator 3 to know the disposition of the ammunition in the enclosure 1.

A titre de variante, le dispositif pourra être couplé à des moyens de détection de menace incorporés au véhicule lui-même et non déportés.Alternatively, the device may be coupled to threat detection means incorporated in the vehicle itself and not deported.

Le logiciel de commande du déplacement des munitions pourra également posséder une capacité d'apprentissage (réseau de neurones) en fonction des paramètres d'une mission.The ammunition movement control software may also have a learning capability (neural network) depending on the parameters of a mission.
