Description
La présente invention concerne une structure d'engin sous-marin tel qu'un sous-marin proprement dit.The present invention relates to an underwater vehicle structure such as a submarine itself.
Plus particulièrement l'invention se rapporte à une structure d'engin sous-marin qui comporte une coque épaisse se présentant au moins sur une partie de sa longueur sous la forme générale d'un cylindre.More particularly, the invention relates to an underwater vehicle structure which comprises a thick shell at least over part of its length in the general shape of a cylinder.
Cette structure peut également comporter d'autres parties telles que par exemple une partie appelée un massif ou encore une partie appelée appareil à gouverner le sous-marin.This structure may also include other parts such as for example a part called a massif or a part called steering gear the submarine.
Différentes études ont mis en évidence l'importance que représentait pour ces structures et en particulier pour les sous-marins, la menace liée aux évolutions et à la prolifération de sonars tels que par exemple des sonars dits actifs.Various studies have highlighted the importance for these structures, and in particular for submarines, of the threat related to sonar evolutions and proliferation such as, for example, so-called active sonars.
Afin de tenir compte de cette menace, des études ont été menées pour réduire l'index de cible c'est-à-dire en fait augmenter la furtivité acoustique d'un sous-marin y compris en très basse fréquence.In order to take this threat into account, studies have been conducted to reduce the target index, that is, to increase the acoustic stealth of a submarine even at very low frequency.
L'amélioration de la furtivité en particulier acoustique d'un sous-marin peut être obtenue principalement de deux manières. En fait il s'agit d'éliminer ou d'annuler l'écho sonar renvoyé par la cible comme par exemple le sous-marin, vers la menace c'est-à-dire le sonar actif adverse.The improvement of the particular acoustic stealth of a submarine can be obtained mainly in two ways. In fact it is to eliminate or cancel the sonar echo returned by the target as for example the submarine, to the threat that is to say the active sonar opponent.
Ainsi l'amélioration de la furtivité d'un sous-marin peut être obtenue en inclinant les différentes parois planes de sa structure par rapport à la verticale, l'onde sonore émise par le sonar adverse est alors réfléchie vers des sites fortement positifs ou fortement négatifs.Thus the improvement of the stealth of a submarine can be obtained by tilting the different flat walls of its structure relative to the vertical, the sound wave emitted by the adverse sonar is then reflected to strongly positive sites or strongly negative.
La menace est en effet dans la plupart des cas, à des sites compris entre plus ou moins 10°, c'est-à-dire à un niveau proche de celui du sous-marin.The threat is indeed in most cases, at sites between plus or
De plus si le sous-marin comporte une coque mince semi transparente placée autour d'une coque épaisse, l'onde sonar est faiblement transmise, ce qui permet de masquer les échos éventuels renvoyés par la structure et divers équipements placés par exemple sous la coque mince de celle-ci.Moreover, if the submarine has a semi-transparent thin shell placed around a thick hull, the sonar wave is weakly transmitted, which makes it possible to hide the possible echoes returned by the structure and various equipment placed for example under the hull. thin of it.
L'amélioration de la furtivité peut également être obtenue en utilisant sur la structure, des revêtements acoustiques absorbants qui permettent de diminuer fortement l'amplitude de l'onde réfléchie par la coque épaisse du sous-marin.The improvement of the stealth can also be obtained by using on the structure, absorbent acoustic coatings which can greatly reduce the amplitude of the wave reflected by the thick hull of the submarine.
Ces revêtements acoustiques absorbants sont également appelés revêtements anéchoïques.These absorbent acoustic coatings are also called anechoic coatings.
L'index de cible d'un sous-marin est en général maximal sur le travers, c'est-à-dire pour des gisements à plus ou moins 90°, du fait de l'écho renvoyé par la partie cylindrique de la coque et dans une moindre mesure, par le massif et l'appareil à gouverner de celui-ci.The target index of a submarine is usually maximum on the skew, that is to say for deposits to plus or minus 90 °, because of the echo returned by the cylindrical part of the hull and to a lesser extent, by the massive and steering gear of this one.
Comme cela a été indiqué précédemment, le massif et l'appareil à gouverner peuvent être traités par l'une ou l'autre des méthodes décrites et la coque cylindrique peut être traitée par un revêtement anéchoïque pour améliorer le plus possible la discrétion du sous-marin.As previously indicated, the boom and steering gear can be treated by either of the methods described and the cylindrical shell can be treated with an anechoic coating to enhance the discretion of the underwater body as much as possible. marine.
Cependant des difficultés importantes apparaissent à basse et très basse fréquence.However, important difficulties appear at low and very low frequency.
En effet soit le revêtement anéchoïque est très épais soit il est peu efficace.Indeed either the anechoic coating is very thick or it is not very effective.
En pratique il est difficile d'obtenir mieux que 6 dB en dessous de 3 kHz et l'anéchoisme en dessous de 1,5 kHz est quasiment impossible.In practice it is difficult to obtain better than 6 dB below 3 kHz and anechoism below 1.5 kHz is almost impossible.
Par ailleurs l'utilisation de ce type de revêtement pose également un problème lié à l'implantation de grandes antennes de flanc pour la détection sonar passive.Moreover, the use of this type of coating also poses a problem related to the implantation of large flank antennas for passive sonar detection.
En effet il y a un conflit entre cette utilisation de grandes antennes et l'implantation de revêtement anéchoïque sur certaines portions de la coque cylindrique.Indeed, there is a conflict between this use of large antennas and the implantation of anechoic coating on certain portions of the cylindrical shell.
On sait par exemple que des constructeurs de sous-marins ont proposé d'implanter des antennes de flanc sur des revêtements anéchoïques.It is known, for example, that submarine manufacturers have proposed to implant flanking antennas on anechoic coatings.
Cependant ceci présente plusieurs inconvénients :
- Le revêtement anéchoïque, même en couche épaisse, présente des performances médiocres en très basse fréquence. De plus la compressibilité importante de ce revêtement en fonction de la pression hydrostatique est pénalisante pour les bilans d'architecture navale.
- La présence de revêtement de ce type sous une antenne de flanc dégrade les performances de celle-ci à basse fréquence. En effet on ne dispose pas de réflecteur dur derrière les capteurs de cette antenne et des interférences acoustiques apparaissent en raison des réflexions sur la coque située derrière le revêtement anéchoïque.
- The anechoic coating, even in thick layer, has poor performance at very low frequency. In addition, the significant compressibility of this coating as a function of the hydrostatic pressure is penalizing for naval architecture assessments.
- The presence of such coating under a sidewall antenna degrades the performance thereof at low frequency. Indeed we do not have a hard reflector behind the sensors of this antenna and acoustic interference appear due to reflections on the hull behind the anechoic coating.
D'autres constructeurs de sous-marins ont proposé d'utiliser des appendices acoustiques ajoutés en particulier sur la partie cylindrique de la coque épaisse du sous-marin.Other submarine builders have proposed using acoustic appendages added especially on the cylindrical portion of the submarine's hull.
Cependant toutes ces solutions n'ont pas donné pleinement satisfaction car il est difficile d'assurer à la fois une bonne furtivité acoustique du sous-marin par le travers, de permettre une bonne intégration de grandes antennes sonar de flanc et d'assurer une protection contre les chocs latéraux de la coque épaisse.However all these solutions have not given full satisfaction because it is difficult to ensure both good acoustic stealth of the submarine by the skew, to allow good integration of large sonar flank antennas and provide protection against side impacts of the thick shell.
Le but de l'invention est donc de résoudre ces problèmes.The object of the invention is therefore to solve these problems.
A cet effet l'invention a pour objet une structure d'engin sous-marin selon la revendication 1.For this purpose the invention relates to an underwater vehicle structure according to claim 1.
Selon d'autres caractéristiques, la structure suivant l'invention la structure d'engin sous-marin est conforme à l'une ou plusieurs des revendications 2 à 8.According to other features, the structure according to the invention the underwater vehicle structure is in accordance with one or more of
L'invention sera mieux comprise à la lecture de la description qui va suivre donnée uniquement à titre d'exemple et faite en se référant aux dessins annexés sur lesquels :
- la
figure 1 représente une vue partielle d'un tronçon de coque épaisse de forme générale cylindrique d'un engin sous-marin selon l'invention et sur un flanc duquel est installé un déflecteur acoustique ; et - les
figures 2 et 3 représentent des vues partielles illustrant des variantes de réalisation de ce déflecteur.
- the
figure 1 is a partial view of a thick hull section of generally cylindrical shape of an underwater vehicle according to the invention and on whose side is installed an acoustic deflector; and - the
Figures 2 and 3 represent partial views illustrating embodiments of this deflector.
Ainsi que cela est illustré sur ces figures, l'invention se rapporte à une structure d'engin sous-marin tel que notamment un sous-marin proprement dit.As is illustrated in these figures, the invention relates to an underwater vehicle structure such as in particular a submarine proper.
Un sous-marin comporte de façon générale, une coque épaisse se présentant au moins sur une partie de sa longueur, sous la forme générale d'un cylindre, cette partie de coque épaisse étant désignée par la référence générale 1 sur ces figures.A submarine generally comprises a thick hull at least a portion of its length, in the general shape of a cylinder, this thick hull portion being designated by the general reference 1 in these figures.
Selon l'invention les flancs latéraux de cette partie cylindrique de coque épaisse sont munis sur au moins une partie de leur longueur, de moyens formant déflecteur acoustique, dont l'un est désigné par la référence générale 2 sur ces figures.According to the invention the side flanks of this cylindrical portion of thick shell are provided over at least a part of their length, means forming an acoustic deflector, one of which is designated by the
En fait ces moyens formant déflecteur acoustique comportent comme cela est illustré en particulier sur les
Sur ces figures, l'un des organes d'habillage de section en V couchés contre la coque épaisse, est désigné par la référence générale 3 et comporte par exemple une plaque métallique à pans inclinés de part et d'autre de l'arête centrale de celui-ci, désignés par les références générales 4 et 5.In these figures, one of the V-section dressing members coated against the thick shell, is designated by the general reference 3 and comprises for example a metal plate inclined sides on either side of the central ridge of this, designated by
Cette plaque métallique présente par exemple une épaisseur comprise entre 8 et 10 mm.This metal plate has for example a thickness of between 8 and 10 mm.
Les pans de la plaque en V couché peuvent être inclinés d'un angle au moins égal à 15° par rapport à a verticale.The sides of the coated V-plate can be inclined at an angle of at least 15 ° with respect to vertical.
Comme cela a été indiqué précédemment, des moyens d'amortissement sont prévus entre ces organes d'habillage et le reste de la coque.As indicated above, damping means are provided between these trim members and the rest of the hull.
Ces moyens sont désignés par la référence générale 6 sur ces figures et comportent par exemple n'importe quelle structure d'amortisseur classique par exemple à barre, à tubes télescopiques ou autre.These means are designated by the
Plusieurs amortisseurs sont alors répartis par exemple le long de la plaque entre celle-ci et le reste de la coque.Several dampers are then distributed for example along the plate between it and the rest of the hull.
Ces amortisseurs 6 permettent ainsi d'amortir les chocs éventuels sur les flancs de la coque épaisse, et d'éviter la transmission de vibrations de la coque vers les déflecteurs, ce qui est favorable à la réduction du bruit rayonné par le sous-marin et donc à la discrétion acoustique de celui-ci.These
Chaque pan de l'organe d'habillage peut alors être formé par une portion de plaque de matériau métallique plane telle que celle désignée par la référence générale 7 sur la
Un revêtement acoustique de type matériau mou, c'est-à-dire de faible impédance acoustique avec une épaisseur typique de 20 à 30 mm, est prévu par exemple sur la face interne de celle-ci. Ce revêtement est désigné par la référence générale 8 sur la
Cette configuration permet alors de réduire significativement l'index de cible du sous-marin sur le travers et ce même à très basse fréquence.This configuration then makes it possible to significantly reduce the target index of the submarine on the skew, even at very low frequency.
Une réduction par exemple de 10 à 15 dB est atteignable à 1,5 kHz.A reduction of, for example, 10 to 15 dB is attainable at 1.5 kHz.
De plus et comme cela est illustré sur la
Cette antenne sonar de flanc pointe alors vers les sites négatifs comme cela ressort de cette figure.This flanking sonar antenna then points to the negative sites as is apparent from this figure.
On sait en effet que le pointage vers les sites négatifs est plus favorable en terme de rapport signal/bruit.It is known that pointing to negative sites is more favorable in terms of signal-to-noise ratio.
La réponse acoustique de l'antenne dans les basses fréquences peut également être améliorée en utilisant des baffles additionnels comme cela est connu par ailleurs.The acoustic response of the antenna at low frequencies can also be improved by using additional speakers as is known elsewhere.
Sur la
Cet ensemble plaque et couche forme alors un baffle additionnel désigné par la référence générale 11 sur cette
Bien entendu différents modes de réalisation de ces organes d'habillage et en particulier des pans ou des plaques planes entrant dans la constitution de ceux-ci, de même que des moyens formant amortisseur, peuvent être envisagés.Of course, various embodiments of these cladding members and in particular flats or flat plates forming part of their constitution, as well as damping means, can be envisaged.
Ainsi par exemple les parties planes c'est-à-dire les pans de cette structure de déflecteur, peuvent également être réalisés en matériau composite afin de permettre un gain de masse, à l'exception des zones de réception des antennes sonar, dans lesquelles ces pans sont nécessairement en matériau à forte impédance acoustique c'est-à-dire par exemple en acier.Thus, for example, the plane portions, that is to say the sections of this deflector structure, may also be made of composite material in order to allow a gain in mass, with the exception of the sonar antenna reception zones, in which these sections are necessarily of high acoustic impedance material that is to say for example steel.
La forme de la structure du déflecteur acoustique peut également venir accoster la coque épaisse selon différentes configurations en se raccordant au pont de l'engin sous-marin ou non.The shape of the acoustic baffle structure can also come dock the thick hull in different configurations by connecting to the deck of the underwater vehicle or not.
De plus, les zones situées entre les organes d'habillage et la coque épaisse permettent d'intégrer certains équipements de petites dimensions à l'extérieur de cette coque.In addition, the areas between the dressing members and the thick shell allow to integrate some small equipment outside of this shell.
De même on peut notamment y faire circuler des câbles électriques par exemple pour l'alimentation et la récupération des signaux des antennes sonar de flanc.In the same way, it is possible to circulate electric cables therefor, for example, for feeding and recovering the signals of the flanking sonar antennas.
Bien entendu d'autres modes de réalisation encore peuvent être envisagés.Of course other embodiments can be envisaged.
