Definitions
- Underwater gear structure such as a submarine
- the present invention relates to an underwater vehicle structure such as a submarine proper.
- 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.
- This structure may also include other parts such as for example a part called a solid or a part called steering gear the submarine.
- 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.
- 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.
- the threat is indeed in most cases, at sites between plus or minus 10 °, that is to say at a level close to that of the submarine.
- 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.
- 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.
- absorbent acoustic coatings are also called anechoic coatings.
- the target index of a submarine is generally 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 the hull.
- 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.
- the anechoic coating even in thick layer, has poor performance at very low frequency.
- the significant compressibility of this coating as a function of the hydrostatic pressure is penalizing for naval architecture assessments.
- the object of the invention is therefore to solve these problems.
- the subject of the invention is an underwater vehicle structure, of the type comprising a thick hull at least over part of its length, in the general form of a cylinder, characterized in that the lateral flanks of this structure comprise on at least a part of the length of the cylinder, means forming an acoustic baffle comprising on each side of the thick shell, dressing members V section, recumbent against the hull and associated with the hull through damping means of shock and noise.
- the dressing members are at least partly metallic
- the dressing members are made from plates of metallic material; the plates comprise inclined faces;
- the plates have a thickness of between 8 and 10 mm;
- the inclined faces of the plates are inclined at least 15 ° with respect to the vertical;
- the lower pan of the V-section dressing members has, on its outer face, means forming a sonar flank antenna
- the lower pan of the V-section cladding members has, on its internal face, means forming an additional acoustic baffle.
- FIG. 1 shows 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 baffle;
- FIG. 2 and 3 show partial views illustrating embodiments of this deflector.
- the invention relates to an underwater vehicle structure such as in particular a submarine proper.
- 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.
- 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 general reference 2 in these figures.
- these means forming an acoustic baffle comprise, as is illustrated in particular in FIGS. 2 and 3, on each side of the thick shell 1, V-section cladding members, lying against the thick hull of the submarine and associated with this hull through means of damping shocks and noises, of which one end is connected to the trim member and the other end is connected to the hull of the submarine, for example.
- 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 general references 4 and 5.
- This metal plate has for example a thickness of between 8 and
- the sides of the coated V-plate can be inclined at an angle of at least 15 ° with respect to vertical.
- damping means are provided between these trim members and the rest of the hull.
- These means are designated by the general reference 6 in these figures and comprise for example any conventional shock absorber structure for example bar, telescopic tubes or other.
- dampers are then distributed for example along the plate between it and the rest of the hull.
- dampers 6 thus make it possible to damp the possible shocks on the sides of the thick hull, and to prevent the transmission of vibrations from the hull to the baffles, which is favorable to the reduction of the noise radiated by the submarine and therefore at the acoustic discretion of it.
- Each part of the covering member may then be formed by a flat metal material plate portion such as that designated by the general reference 7 in FIG.
- An acoustic coating of soft material type that is to say low acoustic impedance with a typical thickness of 20 to 30 mm, is provided for example on the inner face thereof.
- This coating is designated by the general reference 8 in FIG.
- This configuration then makes it possible to significantly reduce the target index of the submarine on the skew, even at very low frequency.
- a reduction of, for example, 10 to 15 dB is attainable at 1.5 kHz.
- This flanking sonar antenna then points to the negative sites as is apparent from this figure. It is known that pointing to negative sites is more favorable in terms of signal-to-noise ratio.
- the acoustic response of the antenna at low frequencies can also be improved by using additional speakers as is known elsewhere.
- the flanking sonar antenna module is designated by the general reference numeral 10 and is thus installed on the outer face of the corresponding lower flange 5 of the plate forming the deflector member, whereas the internal face of this flap It comprises an additional plate for example of steel typically of thickness 10 to 20 mm and a layer of soft material typically 20 to 40 mm thick.
- This plate and layer assembly then forms an additional cabinet designated by the general reference January 1 in this figure 3, on the inner face of the corresponding pan 5 of the plate.
- 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.
- 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.
- the areas between the dressing members and the thick shell allow to integrate some small equipment outside of this shell.
