DISPOSITIF PERMETTANT LA FLOTTAISON DES BOITES NOIRES EN CAS DE CRASH D'UN AERODYNE EN MER. 000OO000 Lorsqu'un crash d'avion se produit én mer, les boîtes noires peuvent descendre au fond de l'eau jusqu'à une profondeur qui peut atteindre plusieurs kilomètres, ce qui rend leur récupération extrêmement difficile si non impossible. DEVICE FOR FLOTATION OF BLACK BOXES IN CASES OF CRASH OF AERODYNE AT SEA. 000OO000 When an airplane crash occurs at sea, the black boxes can descend to the bottom of the water to a depth that can reach several kilometers, making their recovery extremely difficult if not impossible.
Munir ces boîtes noires de flotteurs permanents apparaît nécessiter un équipement complexe inadaptable aux boites noires en usage actuellement. To equip these black boxes of permanent floats appears to require a complex equipment unsuitable for the black boxes in current use.
Par compte, les adapter à un dispositif d'une extrême simplicité comportant un système gonflable qui ne se met en oeuvre uniquement qu'au moment où l'aéronef est dans l'eau est une solution d'une extrême simplicité que la présente invention va exposer. By account, adapting them to a device of extreme simplicity comprising an inflatable system that is implemented only when the aircraft is in the water is a solution of extreme simplicity that the present invention is going to exposing.
Les boites noires en usage actuellement peuvent tenir exploitables un mois en 20 Immersion à 6 000 mètres de profondeur selon le BEA ( Bureau d'Enquêtes et d'Analyses ) et l'intervention de sous-marins spécialisés peut toujours intervenir avec des moyens de mise en oeuvre considérables. The black boxes currently in use may be exploitable for one month in 20 Immersion at 6,000 meters depth according to the BEA (Bureau of Investigation and Analysis) and the intervention of specialized submarines can always intervene with means of putting considerable work.
Techniquement les boites noires qui sont orange vif en réalité, sont deux par 25 avion de ligne et elles effectuent des enregistrements dès que l'avion est alimenté électriquement. Technically the black boxes, which are bright orange in reality, are two per 25 airliner and they make recordings as soon as the aircraft is electrically powered.
L'une de ces boîtes noires est située à l'arrière de l'appareil pour enregistrer les conversations et l'autre est située dans la queue pour enregistrer les paramètres de vol notamment la position des gouvernes et les alarmes 30 diverses à raison d'environ 1000 informations par seconde par les AIRBUS qui sont munis d'une mémoire électronique sans pièces mobiles équipée d'un autotest effectuant la vérification des circuits et composants. One of these black boxes is located at the back of the aircraft to record the conversations and the other is located in the queue to record the flight parameters, including the control surface position and the various alarms. approximately 1000 pieces of information per second by the AIRBUS which are provided with an electronic memory without moving parts equipped with a self-test performing the verification of circuits and components.
Ces boites sont robustes pouvant supporter un écrasement par une masse de 35 230 Kg tombant de 3 mètres de haut, plus une exposition à une flamme de 1 100 °C pendant 60 minutes, une immersion en mer d'un mois à plus de 3 m de profondeur et des températures entre -50 et + 70 °C. These boxes are robust and can withstand crushing by a mass of 35 230 Kg falling from 3 meters high, plus exposure to a flame of 1100 ° C for 60 minutes, immersion at sea from one month to more than 3 m depth and temperatures between -50 and + 70 ° C.
Une immersion à plusieurs kilomètres de profondeur les rend inexploitables 40 sauf par une récupération avant le délai d'un mois qui suit cette immersion, ce qui est d'une extrême complexité hors le coût de l'opération. An immersion several kilometers deep makes them unusable 40 except by a recovery before the deadline of one month which follows this immersion, which is of an extreme complexity except the cost of the operation.
Le dispositif selon l'invention peut être incorporé très simplement sur toutes les boites noires existantes sans apport d'un poids supplémentaire significatif 45 et ce dispositif comporte essentiellement une enceinte contenant un gaz comprimé tel que de l'air, une balise gonflable, un bloc de matière solide soluble à l'eau de mer tel que du sel et un émetteur radio de détresse. 2946321 =2 1 Ce dispositif selon l'invention repéré A dans son ensemble, va être exposé en détail ci- après à l'appui des dessins annexés. The device according to the invention can be incorporated very simply on all the existing black boxes without the addition of a significant additional weight 45 and this device essentially comprises an enclosure containing a compressed gas such as air, an inflatable beacon, a block of solids soluble in seawater such as salt and a radio distress transmitter. 2946321 = 2 1 This device according to the invention marked A as a whole, will be described in detail below with reference to the accompanying drawings.
La figure 1 représente en coupe axiale, l'ensemble de ce dispositif incorporant 5 la boîte noire repérée 1 et cette incorporation est réalisée à l'aide par exemple d'un filet en matière plastique tel qu'en nylon par exemple repéré 2 laissant une ouverture 3 permettant la connexion du cylindre repéré 5 avec la balise repérée 4 et qui est normalement totalement vide. 10 Le dispositif actif comporte une enceinte cylindrique repérée 5 avec un conduit repéré 6 assurant une liaison entre cette enceinte 5 avec la balise gonflable 4 et en outre, une valve repérée assure le gonflage en gaz tel qu'air comprimé. FIG. 1 represents, in axial section, the assembly of this device incorporating the black box marked 1 and this incorporation is carried out using, for example, a netting made of nylon such as nylon, for example opening 3 for connecting the cylinder marked 5 with the tag marked 4 and which is normally completely empty. The active device comprises a cylindrical enclosure marked 5 with a marked duct 6 providing a connection between the enclosure 5 with the inflatable beacon 4 and furthermore, a valve marked ensures the inflation of gas such as compressed air.
L'extrémité de ce cylindre 5, situe en glissement, un élément cylindrique 15 repéré 8 et l'étanchéité totale qui va résulter de la pression de l'air comprimé, est assurée par un joint annulaire repéré 9 tandis que le blocage axial est assuré par un bloc soluble repéré 11 et le fond du cylindre 10 est perforé. The end of this cylinder 5, located in sliding, a cylindrical element 15 marked 8 and the total sealing that will result from the pressure of the compressed air, is provided by an annular seal marked 9 while the axial locking is ensured. by a soluble block marked 11 and the bottom of the cylinder 10 is perforated.
Entre cet élément cylindrique 8 et le fond perforé 10, est donc disposé le bloc 20 circulaire soluble dans l'eau, repéré 11 et qui peut être du sel par exemple. Between this cylindrical element 8 and the perforated bottom 10, is thus arranged the water-soluble circular block, marked 11 and which may be salt for example.
En l'état de repos tel que disposé sur l'aéronef, de l'air comprimé a été envoyé dans l'enceinte 5 par la valve 7 et l'élément cylindrique 8 obture la voie de communication 6 de l'air comprimé contenu dans la chambre 5 avec la balise 25 4 et ce par la présence du bloc 11 de telle sorte que cette balise 4 se trouve vide d'air, l'ensemble du dispositif A étant alors ainsi en état opérationnel. In the state of rest as arranged on the aircraft, compressed air has been sent into the chamber 5 by the valve 7 and the cylindrical element 8 closes the communication channel 6 of the compressed air contained in the chamber 5 with the beacon 25 4 and this by the presence of the block 11 so that the beacon 4 is empty of air, the entire device A is then thus in operational state.
Lorsque le dispositif A tombe à l'eau, peu importe la position dans laquelle il va se trouver car le bloc 11 va commencer à se dissoudre par la pénétration 30 de l'eau par les ouvertures du fond perforé 10 et le déplacement de l'élément cylindrique 8 va commencer à se déplacer sous la pression de l'air comprimé contenue à l'intérieur de l'enceinte 5 libérant ainsi peu à peu la voie du canal 6 gonflant alors la bouée 4 qui, sous l'effet du principe d'Archimède, va placer doucement ledit dispositif en conformité avec la figure 2. 35 Selon cette figure 2, au bout d'un court temps qui va dépendre : 1° du poids de l'ensemble du dispositif, 2° de la distance initiale al dépendant de la distance a 2 qui est l'épaisseur du bloc soluble, 40 Après immersion, le dispositif va se trouver dans la situation selon la figure 2 : 3° distance a 2 = 0, distance al +, 4° l'élément cylindrique 8 va libérer totalement le passage de l'air dans le canal 6 gonflant en totalité da bouée 4 qui va alors se mettre à flotter. 45 II est évident que tous le paramètres déterminant : la pression de l'air, la nature et la dimension du bloc 11 qui peut être de préférence du sel, les volumes de l'enceinte, le volume de la bouée et la conformation du filet d'enrobage, sont à déterminer en fonction des cas d'espèce. 5 2946321 -3- 1 De plus et une fois mis en flottaison, la bouée 4 peut être munie d'un appareil radio d'émission de détresse repéré 12 a - a. logé dans le dispositif relié par fils 12 c à une antenne 12 b fixée par adhésion sur le dessus de la bouée 4, ce qui peut ainsi alerter immédiatement dès flottaison, les autontés de sauvetage When the device A falls into the water, it does not matter what position it will be in because the block 11 will begin to dissolve by the penetration of the water through the openings of the perforated bottom 10 and the displacement of the cylindrical element 8 will begin to move under the pressure of the compressed air contained inside the chamber 5 thus gradually releasing the channel 6 then swelling the buoy 4 which, under the effect of the principle of Archimedes, will gently place said device in accordance with Figure 2. According to this Figure 2, after a short time that will depend: 1 ° the weight of the entire device, 2 ° of the initial distance al depending on the distance a 2 which is the thickness of the soluble block, 40 After immersion, the device will be in the situation according to FIG. 2: 3 ° distance a 2 = 0, distance al +, 4 ° the cylindrical element 8 will completely release the passage of air in the 6 swelling channel in total da buoy 4 which will then start to float. It is obvious that all the determining parameters: the air pressure, the nature and the size of the block 11 which may preferably be salt, the volumes of the enclosure, the volume of the buoy and the conformation of the net coating, are to be determined depending on the particular case. In addition and once floated, the buoy 4 may be provided with a radio distress transmitter marked 12 a - a. housed in the device connected by son 12 c to an antenna 12b fixed by adhesion on the top of the buoy 4, which can immediately alert the flotation, the self-rescue
permettant ainsi de sauver de la sorte et qui sait, des vies humaines. A l'évidence, les dispositifs selon l'invention au nombre de 2 par aéronef doivent être placés à l'arrière dans un emplacement faisant que, quelque soit le genre du crash, elles soient à même d'être mise à l'eau dès ce crash. 10 Le dispositif selon l'invention pourrait être éventuellement adapté à d'autres appareils que des boites noires tels que par exemple des objets précieux, etc... thus allowing to save in this way and who knows, human lives. Obviously, the devices according to the invention of 2 by aircraft must be placed at the rear in a location that, whatever the type of crash, they are able to be launched soon this crash. The device according to the invention could possibly be adapted to other devices than black boxes such as for example precious objects, etc.
15 La fixation de la bouée 4 sur le canal 6 doit être suffisante avec un collier de serrage repéré 13 adapté pour résister à des vents forts et violents de force "v" et d'être aussi à même de supporter dans ce cas, le poids de l'ensemble du dispositif A . The attachment of the buoy 4 on the channel 6 must be sufficient with a marked clamp 13 adapted to withstand strong and violent winds of force "v" and to be able to withstand in this case, the weight of the entire device A.
Au filet 2, peut être substitué tout autre type d'élément d'enrobage tel qu'un enrobage plastique ou métallique par exemple. To the net 2 may be substituted any other type of coating element such as a plastic or metal coating for example.
Le gaz mis en oeuvre pour assurer le gonflage peut être de toute nature convenant en particulier l'air comprimé qui est la solution la plus simple. j 4 The gas used to ensure inflation can be of any type particularly suitable for compressed air, which is the simplest solution. j 4
