Definitions

  • the present invention relates to a periscopic mast.
  • the invention relates in particular to a periscopic mast for a submarine.
  • optronic periscopic masts which are telescopic.
  • Known periscopic masts with direct optics generally comprise an optical tube placed inside a cylinder which is slidably mounted relative to the hull of the submarine and which, when not in use, goes deep inside the hull of the submarine. Hoisting a periscope mast of the above type requires at least two jacks.
  • Such optical periscopic masts are bulky, promote the instability of the carrier vehicle, increase the master torque of the navigation shelter by the presence of the guide bearings which increases the resistance to travel and reduces acoustic discretion, and require also hydraulic circuits for controlling relatively complex cylinders.
  • An object of the invention is to propose a periscopic mast with optical channels, in particular for submarines, which makes it possible to remedy the drawbacks of known devices thanks in particular to a telescopic design.
  • the periscope mast for an underwater vehicle is of the optical type and comprises at least one optical tube movable in translation around a fixed optical tube secured to the hull of said submarine, said mobile optical tube being carried by a streamlined fairing mounted to slide relative to the hull, the fixed and mobile tubes being coaxial and being provided with optical means allowing the routing of the optical beams coming from the upper part of the mobile tube to an observation post in the extension of the fixed tube.
  • the telescopic structure with two coaxial tubes of the mast according to the invention makes it possible to reduce very much substantially the size when it is in the retracted position inside the shell.
  • a single cylinder is sufficient to hoist the movable tube into the position of use, which considerably simplifies the control circuits for hoisting the mast.
  • Another subject of the invention is an installation comprising two periscopic masts, at least one of which is a periscopic mast of the optical type according to the invention, said installation comprising an observation post common to the two masts.
  • FIG 1 there is shown a periscopic mast according to the invention, of optical type, intended to equip for example a submarine (not shown).
  • This mast 1 essentially comprises a first optical tube 3 movable in translation around a second fixed optical tube 2 which is made integral with the hull 4 of the submarine by any suitable means, known in itself and not specific to the invention.
  • the movable tube 3 which is coaxial with the fixed tube 2 and of diameter slightly greater than the latter so as to slide around it, is carried by a streamlined streamlined fairing 5 mounted to slide in a recess 6 of the shell 4.
  • the fairing 5 protrudes relative to the hull 4 by about half the time of the height of this fairing 5, this height being moreover substantially equal to the height of the fixed tube 2.
  • the upper end of the fixed tube 2 extends in the movable tube 3.
  • the sliding of the fairing 5 and consequently the hoisting of the movable tube 3 is controlled by a hydraulic cylinder 7, with single or double oil effect, arranged laterally with respect to the fixed 2 and movable 3 tubes.
  • the body 8 of the cylinder 7 is made integral with the shell 4 while its rod 9 is fixed, by its upper end, to the wall of the movable tube 3.
  • the oil supply of the jack 7 is done by a pipe 10 which passes through the shell 4 at the lower end of the body 8 of the jack 7.
  • the emptying of the upper chamber 7a of the jack 7 is done by a separate pipe 11 which runs inside the recess 6 of the shell 4.
  • this return of oil from the upper chamber 7a can be incorporated into the jack 7 itself.
  • the body 8 of the jack 7 extends inside the recess 6 and partially inside the fairing 5 when the latter is in the hoisted position. In the hoisted position of the fairing 5, the rod 9 of the jack 7 extends completely inside the fairing 5.
  • the body 8 of the jack 7 could be directly linked to the fairing 5 while its rod 9 would then be made integral with the shell 4, the hydraulic supplies then being effected by bores made in the rod 9 herself.
  • the means for translational guiding of the profiled fairing 5 are directly incorporated into the structure of the navigation shelter or hull 4 of the submarine, these guiding means being for example devices of the type with runners and runners, said slides being able to be carried by the fairing 5 or by the structure of the navigation shelter 4.
  • the upper end of the movable tube 3 carries a optical head 12, coaxial with this movable tube 3, the internal structure of which can be oriented in bearing by means of electromechanical means not shown but known in themselves carries pointing prisms in elevation (not shown) of the different tracks of the mast 1.
  • the optical head 12 which is sealingly closed at its lower end by an optical device 13 forming a window, is extended by an external cap 14 coaxial with the fixed 2 and mobile tubes 3.
  • this cover 14 is mounted for rotation about the axis XX ′ of the fixed 2 and mobile 3 tubes while sealing and rotation drive means 15 are provided at the base of the cover 14 and at the periphery of that -This, in particular, to achieve a water-tightness between the cap 14 and the optical head 12 opposite the joint plane between the cap 14 and the fairing 5.
  • the outer cap 14 carries portholes (not shown s) passage of the optical beams of the different optical paths of the mast 1.
  • the optical head 12 is movable in rotation independently of the cap 14.
  • the rotation drive and sealing means 15, of the rotating electrical joint type are not specific to the invention and are known in themselves.
  • the mast 1 comprises electronic control means (not shown), arranged in a compartment 16 preferably located at the top of the fairing 5 and connected on the one hand to means of external power supply (not shown) via a first connection cable 17, a connection box 18, and a second connection cable 19, and on the other hand to the cover 14 via a connection cable 20, said control means, known in themselves and not specific to the invention, being designed to "copy” the position of the internal structure of the optical head 12 and align the portholes of the cap 14 with the optical axes of the tracks of the mast 1.
  • the fixed tube 2 comprises at each end an optical device 21 forming a porthole which allows the path to the observation post 22 of the mast 1 located under this mast 1, of the optical beams coming from the cap 14 and which also provide a function of sealing and safety in the event of failure of the other sealing means of the mast 1.
  • the lower end of the fixed tube 2 is extended by a tube 23 coaxial with the fixed tube 2, which extends inside the navigation shelter of the submarine and which contains a mirror 24 allowing the return to the station observation 22 of the optical beams coming from the cap 14.
  • the observation station 22 also groups together all of the control means of the mast 1. It is also possible to centralize on a strip worn by the observer 25 l all the strategic information necessary for the control of the vessel such as in particular the depth of immersion, the course, the azimuth of the goal, the radar alert, the speed, the time, etc.
  • the end of the tube 23 adjacent to the lower end of the fixed tube 2 is also sealed off by an optical device forming a window 23a.
  • the fixed tube 2 is centered in a guide bearing 26 fixed by any appropriate means inside the movable tube 3 at the lower end of the fairing 5.
  • the bearing 26 can also be made integral with the tube fixed 2.
  • the bearing 26 has a laminated structure which gives it the ability to "swivel", that is to say allows its deformation in the three directions of space.
  • the bearing 26 is thus produced in the form of a stack of blades 26a in the form of cups alternately metallic and made of synthetic material, the cup 26a adjacent to the fairing 5 being metallic while the cup 26a adjacent to the fixed tube being made of synthetic material.
  • a simple device is thus produced which allows on the one hand a sliding between the fixed tube 2 and the movable tube 3 and on the other hand to remedy the misalignments and deformations of the fairing 5 due to the stresses applied on it .
  • the watertightness between the fairing 5 and the fixed tube 2 is achieved by means of a membrane 27 compressible along the axis XX ′ of the fixed 2 and mobile 3 tubes and made integral with the fixed tube 2.
  • the membrane 27 comprises several membrane elements 27a, preferably made of stainless steel which resists corrosion well, connected together by flanges 27b each provided with an annular seal 27c.
  • the latter is made integral with the fixed tube 2 by means of centering rings 27d provided for this purpose along the fixed tube 2.
  • the upper end of the fairing 5 also supports external antennas 28 for radar emission detection and / or satellite navigation.
  • the mast 1 With two concentric mobile tubes, the sealing of which would be achieved by means of a device similar to the aforementioned membrane 27.
  • the fairing 5 would slide in an intermediate device which would itself guided in the navigation shelter 4, the hoisting of the intermediate device being obtained by a press disposed between the two aforementioned concentric tubes.
  • the cap 14 and the optical head 12 form one and the same element 30 mounted for rotation about the axis XX ′ of the fixed 2 and mobile tubes 3.
  • the means for driving this element 30 and for sealing between this element 30 and the fairing 5, marked 15a in FIG. 2, are of identical design to the means 15 in FIG. 1.
  • a submarine has two periscopic masts.
  • the invention has provided a single operator station 22 for the two periscopic masts (see FIG. 3).
  • the fixed tube of each mast 1 is extended by a tube bent at 90 ° 35, the horizontal parts of each bent tube 35 of each mast 1 extending in the extension of one another.
  • the transfer to the operator station 22 of the optical beams emanating from each of the masts 1 after reflection at 90 ° by a mirror 36 is carried out selectively by permutation of a mirror 37 located at the intersection of the optical beams emanating from each mast.
  • the various commands of the two periscopic masts can be grouped on the operator station 22.
  • a rotary electrical seal 15 which comprises a fixed seal element called stator mounted in abutment against the internal face of the end of the tube 3, and a rotary seal element said rotor which surrounds with play the head 12.
  • the rotor seal element is made to rotate with the cover 14 by means of a drive finger 41 which connects the cover 14 and the rotor seal element.
  • a double annular seal 15b and a set 15c forming bearings and rotating electrical collector for the supply of electrical equipment to the head 12 by means of a flexible supply link 61 so-called feeding trainer.

  • bearings 46 Between the cap 14 and the external face of the end of the tube 3 are interposed bearings 46 which allow rotation of the cap 14.
  • the rotational drive motors 44 and 48 as well as the angular position sensors 45 and 49 are connected to the electronic control means arranged in the compartment 16 by means of a power outlet 57.
  • the sensors 45 and 49 can be replaced by a single sensor 52 which is interposed between the upper end of the head 12 and the cap 14 to a direct measurement of the difference in angular position between the cap 14 and the head 12.
  • the aforementioned means make it possible in particular to produce a mast 1 equipped with a cap 14, called a follower, allowing the "copying" of the position of the structure internal of the optical head 12 and the alignment of the porthole 51 of the cover 14 with the optical axes of the tracks of the mast 1.

  • the rotating electrical joint 15a has the particularity to be filled with oil whose pressure is balanced with the immersion pressure of the mast.
  • the angular position sensor 55 is connected to a socket 60 for controlling the motor 54 in position which is itself connected to socket 60 while the element 30 comprises a supply socket 58 for these electrical equipment items itself connected to a socket 59 for connection to the edge of the underwater vehicle. More explicitly, the sockets 60 and 59 are connected to the operating consoles 32 of the submarine.
  • the rotary element of the rotary joint is also made integral with the element 30 by means of an arm 56.
  • the aforementioned equipment thus allows the element 30 to be controlled in position, remotely from the consoles 32.
  • the telescopic structure of the masts according to the invention essentially allows the realization of an optical vision without penetration of hoisting elements inside the thick hull of the submarine, flexibility in fitting out the operational space in parallel with a fixed station operation, reducing the masses in the upper part of the navigation shelter, increasing the stability of the carrier vehicle, reducing the main torque of the shelter navigation due to the removal of the guide bearings which reduces the resistance to advancement and also increases the acoustic discretion and finally a significant simplification of the hydraulic control circuits of the masts.
