Description
DESCRIPCIONDESCRIPTION
Estructura de vehlcuio submarino tal como un submarino.Underwater vehicle structure such as a submarine.
5 [0001] La presente invencion se refiere a una estructura de vehlcuio submarino tal como un submarino[0001] The present invention relates to an underwater vehicle structure such as a submarine
propiamente dicho.Properly said.
[0002] Mas particularmente, la invencion se refiere a una estructura de vehlcuio submarino que consta de un casco grueso que se presenta al menos sobre una parte de su longitud bajo la forma general de un cilindro.[0002] More particularly, the invention relates to an underwater vehicle structure consisting of a thick hull that is presented at least over a part of its length in the general form of a cylinder.
1010
[0003] Esta estructura puede constar igualmente de otras partes tales como, por ejemplo, una parte llamada vela o incluso una parte llamada aparato para dirigir el submarino.[0003] This structure may also consist of other parts such as, for example, a part called a sail or even a part called an apparatus for directing the submarine.
[0004] Diferentes estudios han puesto de manifiesto la importancia que representaba para estas estructuras 15 y, en particular, para los submarinos, la amenaza unida a las evoluciones y a la proliferacion de sonares tales como,[0004] Different studies have shown the importance it represented for these structures 15 and, in particular, for submarines, the threat linked to evolutions and the proliferation of sonars such as,
por ejemplo, unos sonares denominados activos.for example, sonars called assets.
[0005] A fin de tener en cuenta esta amenaza, se han llevado a cabo unos estudios para reducir el Indice de objetivo, es decir aumentar de hecho la tecnologla de sigilo acustica de un submarino inclusive a frecuencia muy[0005] In order to take this threat into account, studies have been carried out to reduce the target Index, that is, to increase in fact the acoustic stealth technology of a submarine, even at a very frequent frequency.
20 baja.20 low.
[0006] La mejora de la tecnologla de sigilo en particular acustica de un submarino se puede obtener principalmente de dos maneras. De hecho, se trata de eliminar o anular el eco sonar reenviado por el objetivo como, por ejemplo, el submarino, hacia la amenaza, es decir el sonar activo adverso.[0006] The improvement of the particular acoustic stealth technology of a submarine can be obtained mainly in two ways. In fact, it is about eliminating or canceling the echo sonar forwarded by the target such as, for example, the submarine, towards the threat, that is, the adverse active sound.
2525
[0007] Asl, la mejora de la tecnologla de sigilo de un submarino se puede obtener inclinando las diferentes paredes planas de su estructura con respecto a la vertical, la onda sonora emitida por el sonar adverso se refleja entonces hacia unos sitios fuertemente positivos o fuertemente negativos.[0007] Thus, the improvement of the stealth technology of a submarine can be obtained by tilting the different flat walls of its structure with respect to the vertical, the sound wave emitted by the adverse sonar is then reflected towards strongly positive or strongly positive sites negative
30 [0008] La amenaza es en efecto, en la mayorla de los casos, a unos sitios comprendidos entre mas o menos30 [0008] The threat is, in most cases, to places between more or less
10°, es decir a un nivel proximo al del submarino.10 °, that is, at a level close to that of the submarine.
[0009] Ademas, si el submarino consta de un casco delgado semi-transparente colocado alrededor de un casco grueso, la onda sonar se transmite debilmente, lo que permite ocultar los ecos eventuales reenviados por la[0009] In addition, if the submarine consists of a semi-transparent thin hull placed around a thick hull, the sonar wave is transmitted weakly, which allows hiding the eventual echoes forwarded by the
35 estructura y diversos equipos colocados por ejemplo bajo el casco delgado de esta.35 structure and various equipment placed for example under the thin hull of this.
[0010] La mejora de la tecnologla de sigilo se puede obtener igualmente utilizando sobre la estructura, unos revestimientos acusticos absorbentes que permiten disminuir fuertemente la amplitud de la onda reflejada por el casco grueso del submarino.[0010] The improvement of the stealth technology can also be obtained by using on the structure, absorbent acoustic coatings that allow to reduce strongly the amplitude of the wave reflected by the thick hull of the submarine.
4040
[0011] Estos revestimientos acusticos absorbentes se denominan igualmente revestimientos anecoicos.[0011] These absorbent acoustic coatings are also referred to as anechoic coatings.
[0012] El documento FR 2 732 806 A1 describe tal revestimiento acustico.[0012] FR 2 732 806 A1 describes such acoustic coating.
45 [0013] El Indice de objetivo de un submarino es en general maximo sobre el costado, es decir para unas[0013] The target Index of a submarine is generally maximum on the side, that is, for some
marcaciones a mas o menos 90°, debido al eco reenviado por la parte cillndrica del casco y en una menor medida, por la vela y el aparato que hay que dirigir de este.markings at more or less 90 °, due to the echo forwarded by the cylindrical part of the hull and to a lesser extent, by the sail and the device to be directed from it.
[0014] Como se ha indicado anteriormente, la vela y el aparato que se va a dirigir pueden ser tratados por 50 uno u otro de los metodos descritos y el casco cillndrico puede ser tratado por un revestimiento anecoico para[0014] As indicated above, the candle and the apparatus to be directed can be treated by one or the other of the methods described and the cylindrical hull can be treated by an anechoic coating for
mejorar lo maximo posible la discrecion del submarino.improve the submarine's discretion as much as possible.
[0015] No obstante, unas dificultades importantes aparecen a baja y muy baja frecuencia.[0015] However, important difficulties appear at low and very low frequency.
55 [0016] En efecto, o el revestimiento anecoico es muy grueso o es poco eficaz.[0016] Indeed, either the anechoic coating is very thick or inefficient.
[0017] En la practica, es diflcil obtener nada mejor que 6 dB por debajo de 3 kHz y el anecoismo por debajo[0017] In practice, it is difficult to obtain anything better than 6 dB below 3 kHz and anecoism below
de 1,5 kHz es casi imposible.1.5 kHz is almost impossible.
[0018] Por otro lado, la utilization de este tipo de revestimiento supone igualmente un problema unido a la implantation de grandes antenas de flanco para la detection sonar pasiva.[0018] On the other hand, the use of this type of coating is also a problem linked to the implantation of large flank antennas for passive sonar detection.
[0019] En efecto, hay un conflicto entre esta utilizacion de grandes antenas y la implantacion de revestimiento 5 anecoico sobre ciertas porciones del casco cillndrico.[0019] Indeed, there is a conflict between this use of large antennas and the implantation of anechoic coating on certain portions of the cylindrical hull.
[0020] Se sabe, por ejemplo, que unos fabricantes de submarinos han propuesto implantar unas antenas de flanco sobre unos revestimientos anecoicos.[0020] It is known, for example, that some submarine manufacturers have proposed to implant flank antennas on anechoic coatings.
10 [0021] No obstante, esto presenta varios inconvenientes:10 [0021] However, this has several drawbacks:
- El revestimiento anecoico, incluso en capa gruesa, presenta unos rendimientos mediocres en frecuencia muy baja. Ademas, la compresibilidad importante de este revestimiento en funcion de la presion hidrostatica es perjudicial para los balances de arquitectura naval.- The anechoic coating, even in thick layer, has mediocre yields in very low frequency. In addition, the important compressibility of this coating as a function of hydrostatic pressure is detrimental to naval architecture balances.
15fifteen
- La presencia de revestimiento de este tipo bajo una antena de flanco degrada los rendimientos de esta a baja frecuencia. En efecto, no se dispone de reflector duro detras de los sensores de esta antena y unas interferencias acusticas aparecen debido a unas reflexiones sobre el casco situado detras del revestimiento anecoico.- The presence of this type of coating under a flank antenna degrades its performance at low frequency. In fact, there is no hard reflector behind the sensors of this antenna and acoustic interference appears due to reflections on the hull behind the anechoic lining.
20 [0022] Otros fabricantes de submarinos han propuesto utilizar unos apendices acusticos anadidos en20 [0022] Other submarine manufacturers have proposed using acoustic appendices added in
particular sobre la parte cillndrica del casco grueso del submarino.particular on the cylindrical part of the thick hull of the submarine.
[0023] No obstante, todas estas soluciones no son del todo satisfactorias ya que es diflcil garantizar a la vez una buena tecnologla de sigilo acustica del submarino por el costado, permitir una buena integration de grandes[0023] However, all these solutions are not entirely satisfactory since it is difficult to guarantee at the same time a good acoustic stealth technology of the submarine on the side, allow a good integration of large
25 antenas sonar de flanco y garantizar una protection contra los choques laterales del casco grueso.25 sonar flank antennas and ensure protection against the side shocks of the thick helmet.
[0024] El objetivo de la invention es por tanto resolver estos problemas.[0024] The aim of the invention is therefore to solve these problems.
[0025] A tal efecto, la invencion tiene como objeto una estructura de vehlculo submarino segun la 30 revindication 1.[0025] For this purpose, the invention has as its object an underwater vehicle structure according to 30 revindication 1.
[0026] Segun otras caracterlsticas, la estructura segun la invencion de vehlculo submarino es conforme a una o varias de las reivindicaciones de 2 a 8.[0026] According to other characteristics, the structure according to the invention of a submarine vehicle is in accordance with one or more of claims 2 to 8.
35 [0027] La invencion se comprendera mejor con la lectura de la description que aparece a continuation dada[0027] The invention will be better understood by reading the description given below.

la referencia general 2 en estas figuras.general reference 2 in these figures.
[0031] De hecho, estos medios que forman deflector acustico constan como se ilustra en particular en las figuras 2 y 3, de cada lado del casco grueso 1, de los organos de preparation de section en V, tumbados contra el[0031] In fact, these means forming an acoustic deflector consist as illustrated in particular in Figures 2 and 3, on each side of the thick hull 1, of the V-section preparation organs, lying against the
55 casco grueso del submarino y asociados a este casco a traves de unos medios de amortiguacion de choques y de ruidos, de los cuales un extremo esta unido al organo de preparacion y el otro extremo esta unido al casco del submarino por ejemplo.55 coarse hull of the submarine and associated with this hull through means of shock and noise damping, of which one end is attached to the preparation organ and the other end is attached to the submarine hull for example.
[0032] En estas figuras, uno de los organos de preparacion de seccion en V inclinados contra el casco[0032] In these figures, one of the V-section preparation organs inclined against the helmet

[0034] Los lados de la placa en V inclinada pueden estar inclinados en un angulo al menos igual a 15° con respecto a la vertical.[0034] The sides of the inclined V-plate may be inclined at an angle at least equal to 15 ° with respect to the vertical.
[0035] Como se ha indicado anteriormente, unos medios de amortiguacion estan previstos entre estos 10 organos de preparacion y el resto del casco.[0035] As indicated above, damping means are provided between these 10 preparation organs and the rest of the helmet.
[0036] Estos medios estan designados por la referencia general 6 en estas figuras y constan por ejemplo de cualquier estructura de amortiguador clasico por ejemplo de barra, de tubos telescopicos u otra.[0036] These means are designated by the general reference 6 in these figures and consist, for example, of any classical shock absorber structure, for example of a rod, telescopic tubes or other.
15 [0037] Varios amortiguadores se distribuyen entonces por ejemplo a lo largo de la placa entre esta y el resto[0037] Several dampers are then distributed, for example, along the plate between it and the rest.
del casco.of the helmet
[0038] Estos amortiguadores 6 permiten amortiguar as! los choques eventuales sobre los flancos del casco grueso y evitar la transmision de vibraciones del casco hacia los deflectores, lo que es conveniente a la reduccion[0038] These 6 dampers allow cushioning as! the eventual shocks on the flanks of the thick hull and avoid the transmission of vibrations from the hull to the baffles, which is convenient to reduce
20 del ruido radiado por el submarino y, por tanto, a la discrecion acustica de este.20 of the noise radiated by the submarine and, therefore, at its acoustic discretion.
[0039] Cada lado del organo de preparacion puede estar formado entonces por una porcion de placa de material metalico plana tal como la designada por la referencia general 7 en la figura 2.[0039] Each side of the preparation organ may then be formed by a portion of flat metal material plate such as that designated by general reference 7 in Figure 2.
25 [0040] Un revestimiento acustico de tipo material blando, es decir de reducida impedancia acustica con un[0040] An acoustic coating of soft material type, that is of reduced acoustic impedance with a
grosor tlpico de 20 a 30 mm, esta previsto por ejemplo sobre la cara interna de esta. Este revestimiento estatypical thickness of 20 to 30 mm, is provided for example on the inner side of it. This coating is
designado por la referencia general 8 en la figura 2.designated by general reference 8 in figure 2.
[0041] Esta configuracion permite entonces reducir significativamente el Indice de objetivo del submarino 30 sobre el lado y esto a muya baja frecuencia.[0041] This configuration then allows the target Index of submarine 30 on the side to be significantly reduced and this at a very low frequency.
[0042] Una reduccion por ejemplo de 10 a 15 dB se puede alcanzar a 1,5 kHz.[0042] A reduction for example from 10 to 15 dB can be reached at 1.5 kHz.
[0043] Ademas y como se ilustra en la figura 3, es igualmente posible utilizar estos organos de preparacion y,[0043] In addition and as illustrated in Figure 3, it is also possible to use these preparation organs and,
35 en particular, el lado inferior 5 de la placa de estos, para instalar una antena sonar de flanco designada por la35 in particular, the lower side 5 of the plate thereof, to install a sonar flank antenna designated by the

[0045] Se sabe en efecto que el marcado hacia los sitios negativos es mas favorable en terminos de relacion senal/ruido.[0045] It is known in effect that marking towards negative sites is more favorable in terms of signal / noise ratio.
[0046] La respuesta acustica de la antena en las bajas frecuencias se puede mejorar igualmente utilizando 45 unos bafles adicionales como se conoce por otro lado.[0046] The acoustic response of the antenna at low frequencies can also be improved by using additional speakers as known on the other hand.
[0047] En la figura 3, el modulo de antena sonar de flanco esta designado por la referencia general 10 y esta instalado por tanto sobre la cara externa del lado inferior correspondiente 5 de la placa que forma el organo deflector, mientras que la cara interna de este consta de una placa adicional por ejemplo de acero de grosor[0047] In Figure 3, the sonar flank antenna module is designated by the general reference 10 and is therefore installed on the external face of the corresponding lower side 5 of the plate forming the deflector organ, while the internal face of this consists of an additional plate for example of thick steel

55 [0049] Por supuesto, diferentes modos de realizacion de estos organos de preparacion y, en particular, de los55 [0049] Of course, different ways of carrying out these preparation organs and, in particular, of the
lados o de las placas planas entran en la constitucion de estos, lo mismo que unos medios que forman amortiguador, se pueden tener en cuenta.sides or of the flat plates enter into the constitution of these, as well as means that form a shock absorber, can be taken into account.
[0050] Asl, por ejemplo, las partes planas, es decir los lados de esta estructura de deflector, se pueden[0050] Thus, for example, flat parts, ie the sides of this baffle structure, can be
realizar igualmente en material compuesto a fin de permitir un aumento de masa, a excepcion de las zonas de recepcion de las antenas sonar, en las cuales estos lados son necesariamente de material de fuerte impedancia acustica, es decir, por ejemplo de acero.also be made of composite material in order to allow an increase in mass, with the exception of the reception areas of the sonar antennas, in which these sides are necessarily of material of strong acoustic impedance, that is, for example of steel.
