Definitions
- TITLE Underwater vehicle of the type comprising at least one hoistable mast
- the present invention relates to an underwater vehicle such as an actual submarine.
- the invention relates to an underwater vehicle of the type comprising at least one hoistable mast, near the end of which are arranged aerial means equipped in particular with sensors or the like, connected to the rest of the equipment of the vessel. 'underwater vehicle.
- an underwater vehicle is for example constituted by a proper submarine.
- a hoistable mast is a mechanism of the underwater vehicle responsible for carrying and deploying aerial means, for example from a kiosk of the underwater vehicle.
- the aerial means for their part form a set, in particular, of sensors integrated into a support and which are connected to the rest of the underwater vehicle, in order to exchange various information with its equipment.
- the aim of the invention is therefore to solve these problems.
- the invention relates to an underwater vehicle of the type comprising at least one hoistable mast, near the upper end of which are arranged aerial means equipped with sensors connected to the rest of the underwater vehicle.
- the hoistable mast comprises at least at its portion intended to cross the dioptre when the mast is hoisted, at least two profiled mast columns in the form of a tapered hydrodynamic profile and spaced apart from each other.
- the bar also has a profile in the form of a tapered hydrodynamic profile
- the columns are made of a material transparent to radar waves
- the columns include passages for connecting means forming aerial means to the rest of the underwater vehicle;
- the aerial means comprise at least one rotating part relative to the rest of the mast; the aerial means have a shape consisting of a stack of parts in a head-to-tail cone;
- the upper part of the aerial means has a shape complementary to the rest of the corresponding part of the underwater vehicle when the mast is lowered in the retracted position in the underwater vehicle.
- FIG. 1 illustrates the creation of a spray of water at the level of the diopter by a hoist mast of a state of the art underwater vehicle;
- FIG. 2 and [Fig. 3] Figures 2 and 3 illustrate an attempt to solve these problems using a mast and aerial means of particular shape, of the state of the art
- FIG. 4 shows a front view of a mast portion forming part of the constitution of an underwater vehicle according to the invention
- Figure 5 shows a perspective view of a portion of this underwater craft mast
- FIG. 6 represents a possible example of a tapered hydrodynamic profile of this mast.
- FIG. 7 shows an exemplary embodiment of aerial means forming part of the constitution of such a machine.
- FIG. 1 a mast of an underwater vehicle such as a submarine proper, of the state of the art.
- the mast proper is designated by the general reference 1 and its upper end comprises aerial means designated by the general reference 2.
- this mast In hoisted position, this mast therefore crosses the diopter, designated by the general reference 3, which causes a shower of water designated by the general reference 4 and a wake designated by the general reference 5, when the underwater vehicle is moving. moves for example with so-called periscopic immersion.
- indiscretions can be linked to the equivalent radar signature of the aerial means, to the spray of water and to the wake or even to the visual and optical or infrared signature of this assembly.
- the aerial means are designated by the general reference 6 and are in fact constituted by a series of portions or conical parts stacked and mounted head to tail.
- Baffles can also be used to reduce water spray and wake.
- this assembly can be coated with a material absorbing radar waves such as an anti-radar material also known by the term MAR, but these different assemblies still have a certain number of drawbacks, which the present application proposes to resolve. .
- the hoist mast is designated by the general reference 10 and the aerial means placed near the upper end thereof, are designated by the general reference 11.
- the hoistable mast 10 comprises at least at the level of its portion intended to cross the diopter, when the mast is hoisted, at least two profiled mast columns in the form of a profile hydrodynamic tapered and spaced apart. These profiled mast columns are designated by the general references 12 and 13 in these figures.
- these columns can have a symmetrical profile or an asymmetric profile.
- mast columns 12 and 13 are also connected by at least one transverse bar designated for example by the general reference 14 in these figures.
- This transverse bar 14 can also have a profile in the form of a tapered hydrodynamic profile.
- these mast columns may include internal passages for means for connecting the aerial means to the rest of the underwater vehicle and in particular to equipment thereof, these passages being designated by the general references 15 and 16 in this FIG. 5 in particular, for the columns 12 and 13 respectively.
- the aerial means 11 may also have a particular shape consisting, for example, of a stack of parts or portions in a head-to-tail cone, stacked on top of each other, such as for example the parts 17 and 18.
- These aerial means may also include at least one rotating part relative to the rest of the mast, this rotating part rotating relative to the rest of these means to make it possible to obtain for example a 360 ° view of the horizon around the pole. 'underwater vehicle.
- the upper part of the aerial means designated by the general reference 19 in this figure, has a shape complementary to that of the rest of the corresponding part of the underwater vehicle. when the mast is lowered in the retracted position in this underwater vehicle.
- the structure thus defined makes it possible to improve the hydrodynamic performance of the mast, particularly at the level of its portion crossing the dioptre to minimize the spray of water and the wake caused during the movement of the machine, for example periscope immersion.
- material transparent to radar waves such as in particular composite materials based on fibers and foam for example, is also possible, thanks to their resistance, while being transparent to radar waves in the frequency band of interest, namely 9 Giga Hz in priority and from 3 to 18 Giga Hz more generally.
- the sensors integrated in the aerial means must be able to be connected to the rest of the underwater vehicle in order to transmit and receive the appropriate information.
- the shape of the aerial means is thus optimized in radar equivalent signature and the plane of rotation of the rotating part thereof can be hidden and masked at a change in slope of the fairing to cone-shaped parts thereof.
