Definitions
- a submarine sails at low immersion it can, for observing the sea surface or communicating with a distant point, raise hoist masts carrying periscopes or antennas; it thus acquires the possibility of making observations or exchanging communications in the various ranges of electromagnetic radiation which propagate in airspace.
- the object of the invention is in particular to provide a submarine with a means of aerial observation, while it is sailing, for safety, at an immersion greater than a few tens of meters.
- the invention proposes another solution.
- the object of the invention is thus an aerial observation and / or communication method for a submarine while diving using a floating body equipped with observation and / or communication means and connected to the submarine. by a retaining cable, this cable ensuring, in addition to the ascent of the body towards the surface of the water and the bringing of this body on board the submarine, the transmission of the observation and / or communication signals between the floating body and the submarine.
- this method consists in releasing the floating body, initially retained on board the submarine and consisting of a device endowed with high buoyancy and low drag, so as to make it rise rapidly to the surface that it crosses by gushing out of the water, activating its means of observation and / or communication at least in the aerial phase of its trajectory, then bringing it back on board the submarine by recalling the cable link.
- the invention takes advantage of the emersion phase of a floating body released at a certain depth, which is due to the kinetic energy which it acquires during its ascent.
- the duration of this emersion although short (a few seconds), nevertheless makes it possible to carry out the desired observation or communication, in particular if we give the machine a structure capable of printing it, during its movement upward, a rotational movement around a vertical axis that it keeps once out of the water, and if we arrange its means of observation and / or communication so that they aim in a direction perpendicular to this axis.
- This spontaneous rotation of the machine on itself elegantly provides a panoramic scanning movement of the horizon with the aforementioned means, without it being necessary to provide any mechanical angular scanning device on board the vehicle.
- the invention also relates to a device for implementing the method defined above.
- This device comprises a streamlined, feathered and gifted with a strong buoyancy, containing observation means such as a television camera or a radar and / or communication antenna such as a radio antenna, and a connection cable. mechanical and electrical attached to the machine and winding on the drum of a motorized winch placed on board the submarine.
- the tail of the machine is shaped so as to impart thereto, when it rises to the surface of the water, a rotational movement on itself around its axis , then oriented vertically, the means of observation and / or communication of the machine aiming in a direction perpendicular to this axis so as to scan the horizon due to this rotational movement.
- a reference gyroscope providing, via the cable to the submarine, the target field of its observation and / or communication means at least during the aerial phase of its path. The bearing angle can thus be known precisely, whatever the roll movements made by the machine during its ascent.
- the latter may include sighting means (possibly constituted by its means of observation) being, when the craft is in the starting position on board the submarine, facing a graduation of deposit surrounding the craft and linked to the submarine.
- sighting means possibly constituted by its means of observation
- the machine is advantageously on board the submarine in a machine launcher tube full of water, which has a door sealed at its mouth and at the bottom of which is the winch actuating the connecting cable.
- This door allows to limit the internal pressure of the tube in deep diving.
- Said tube is preferably oriented obliquely, for example at 45 °, and has an inclination towards the rear of the submarine which, taking into account the forward speed of the latter, facilitates the exit of the machine and its back in the tube. Correct reinsertion of the machine into the tube can also be ensured by providing a pulley for guiding the connecting cable arranged so as to force the latter to run through the tube substantially along the axis thereof.
- this pulley is carried by a floating plug which, placed under the empennage of the machine in the starting position in the tube, rises with the machine when it is released and is stopped by stop means at the mouth of the tube, after having moved therein in a pure translational movement thanks to guide means constituted for example by rails arranged longitudinally on the internal wall of the tube.
- the machine can be equipped with a detector emitting a signal when it leaves the water. This signal can be used to control the rewinding of the connecting cable by the winch so as to bring the machine back on board the submarine.
- the machine can moreover offer a hollow structure, which makes it possible to fill it with a gas under pressure in order to reinforce its resistance with respect to the pressure of water.
- Fig. 1 schematically represents a device according to the invention, showing the machine having left the submarine to accomplish an aerial observation mission.
- Fig. 2 shows in longitudinal section, on a larger scale, the machine launcher tube of the device of FIG. 1.
- a part of the hull 1 of a submarine surmounted by a sheet of superstructure 2 (gangway bridge). Between the hull 1 and the sheet metal 2 is disposed a missile launching tube 3 with an oblique orientation at 45 ° towards the rear of the submarine, which advances in the direction indicated by the arrow 4.
- the mouth of the tube 3 in the sheet 2 is provided with a pivoting waterproof door 5.
- the tube 3 serves as a housing for a vehicle 6 on board the submarine.
- This machine has the external shape of a tapered body so as to have a reduced hydrodynamic drag and has a stabilizing stabilizer 7.
- a. cable 8 which is wound on the drum 9 of a motorized winch placed in immersion at the bottom of the tube 3.
- This cable provides the mechanical connection between the machine 6 and the submarine, as well as the transmission of electrical signals via a rotating connector 10 and an electrical cable 11 penetrating inside d L submarine passing through watertight bushings 12, 13 disposed respectively in the bottom 14 of the tube 3 and in the hull 1 of the submarine.
- the cable 8 is electrically connected to a television camera 15 mounted on board the vehicle 6 and oriented so as to aim - through a transparent porthole 16 - in a direction perpendicular to the longitudinal axis 17 of the craft.
- the fins of the empennage 7 of the craft 6 have folds 18 giving the craft, when it progresses in the water, a rotational movement around its axis 17.
- the cable 8 passes, in the tube 3, over a pulley 19 which substantially maintains it on the axis 20 of the tube.
- This pulley which rotates freely, is carried by a floating plug 21 which can move in translation in the tube 3 by sliding along guide rails 22 arranged on the internal wall of the tube 3 parallel to its axis 20.
- the plug 21 has a peripheral flange 23 having grooves which cooperate with the rails 22, so that the axis of rotation of the pulley 19 remains perpendicular to the vertical plane containing the axis 20 of the tube 3.
- the stroke of the plug 21 in the tube 3 is limited, below, by a circular rib 24 projecting from the internal wall of the tube just above the drum 9 of the winch and, above, by another similar circular rib 25, located at the mouth of tube 3; these ribs cooperate with the bead 23 of the plug 21 to stop the latter either near the bottom 14 of the tube 3 when the machine is in the tube, or, in 21 ', near the mouth of the latter, when the 'machine is out of the tube.
- the movements of the plug 21 within the water which fills the tube 3 are facilitated by at least one hole 26 drilled from one face to the other of the plug to allow the flow of water.
- the machine 6 can move in the tube 3 without the piston effect thanks to the annular gap formed between its outer surface and the inner wall of the tube 3 due to the presence of the rails 22, the water being able to s '' run through this interval.
- the machine picks up speed while its empennage 7, slightly twisted due to the folds 18, prints a rotational movement around its axis 17, which gradually straightens up to the vertical, at low speed due to the position of its center of gravity far below its center of the hull and at high speed by the effect of its empennage 7. Then the craft reaches the surface 27 of the sea, crosses it and springs out at high speed, thanks to the kinetic energy acquired, by turning on itself according to arrow 28. The camera 15 then explores the whole horizon (several times, because the normally makes several turns out of the water) during the few seconds that the aerial phase of the trajectory of the craft lasts, the corresponding views being transmitted to the submarine via cables 8 and 11.
- the machine 6 is provided with a reference gyroscope 30 whose indications, transmitted to the submarine via cables 8 and 11, make it possible to know the deposit corresponding to each view taken by the camera 15.
- a graduation 31 of initial location is marked circumferentially on the internal wall of the tube 3. This graduation, lit by a lamp through the window 16 and located in the field of vision of the camera when the machine is in the starting position at l 'interior of said tube, allows to know the bearing of the line of sight of the camera at the time of launching the machine.
- the indications of the gyroscope 30 can be transmitted in a purely electrical manner.
- a wind rose can be associated with the gyroscope, the image of which, thanks to an adequate optical system, is formed by the camera 15 and transmitted in video form to the submarine, together with the views of the aerial environment.
- the crew of the submarine has a complete vision of the surface of the sea, preferably recorded on video recorder, with indication of the deposit associated with each view. He can decide to surface safely, possibly by changing the route of the submarine.
- the television camera 15 can be installed not horizontally, but vertically in the machine 6, by providing a mirror or a prism to bring its field of vision back to the horizontal when the machine emerges from the water.
- this camera can be a camera with a low level of light, operating at night, or an infrared camera, operating in foggy weather. It can also be replaced by a radar antenna playing the same observation role, or by a UHF antenna allowing the submarine to transmit or receive a radio signal for a few seconds.
- the apparatus 6 should be given a very light structure so that it can reach a high speed at the end of its ascent phase. It is preferably completely hollow and constituted by a tight and resistant skin made of reinforced plastic material such as a glass / resin composite. Its compressive strength can be increased by inflating to 1 or 2 bar with dry air or nitrogen, which also protects its equipment against corrosion and also makes it possible to constantly check its tightness by adding a Pressure sensor.
- the missile launching tube 3 which takes place in the superstructures of the submarine, also contributes to the resistance of the device 6 to the pressure of the water due to the submersion of the submarine. It is constantly full of water, but is kept closed by the watertight door 5 when the submarine is at an immersion greater than the safety immersion, i.e. a few tens of meters, so that the pressure prevailing in the tube 5 and acting on the craft 6 does not exceed a few bars when the submarine is in deep diving.
- the instant when the craft 6 emerges can be detected for example by a humidity detector or a pressure sensor carried by the craft, the signal of which is transmitted to the submarine by the cable 8. A few seconds after this instant, the winch changes direction of rotation and winds the cable 8.
- the cable 8 has an armor, preferably in aromatic polyamide Kevlar, flexible enough in torsion for the machine, during of its rise, can twist the cable a few turns.
- the winch motor is preferably electric rather than hydraulic so as to avoid a hull crossing in addition to the crossing 13.
