Abstract
Description
La présente invention concerne un dispositif de fermeture et de protection d'un système d'évacuation de gaz d'un module de lancement vertical.The present invention relates to a device for closing and protecting a gas discharge system from a vertical launch module.
Les modules de lancement vertical équipant un bâtiment de surface sont généralement encastrés sous le pont du bâtiment et comprennent chacun un système d'évacuation des gaz de propulsion produits lors d'un tir normal d'un missile ou d'un allumage intempestif, qui évacue les gaz de propulsion par l'extrémité supérieure ou par le haut du module.The vertical launch modules fitted to a surface building are generally embedded under the deck of the building and each include a system for evacuating the propellant gases produced during a normal missile launch or an inadvertent ignition, which evacuates propellant gases from the upper end or from the top of the module.
Quelle que soit l'architecture du module de lancement, le système d'évacuation des gaz doit être pourvu d'un dispositif de fermeture qui ne s'ouvre que dans le cas d'un allumage intempestif ou d'un tir normal d'un missile.Whatever the architecture of the launch module, the gas evacuation system must be provided with a closing device which opens only in the event of an accidental ignition or a normal firing of a missile.
Les systèmes d'évacuation à cheminée centrale unique doivent être conçus pour éviter que l'eau de mer, la pluie ou autres objets étrangers ne tombent à l'intérieur de ladite cheminée et provoquer soit un remplissage de la cheminée ou constituer, en ce qui concerne les objets étrangers, des projectiles lors de l'évacuation des gaz.Single central chimney exhaust systems must be designed to prevent seawater, rain or other foreign objects from falling inside the chimney and either cause the chimney to fill up or build up concerns foreign objects, projectiles during the evacuation of gases.
Les dispositifs de fermeture actuellement utilisés sont constitués par une ou plusieurs portes résistantes et motorisées, chaque porte étant munie d'un panneau qui est éjecté lors de l'évacuation de gaz, consécutive à un allumage intempestif.The closing devices currently used consist of one or more resistant and motorized doors, each door being provided with a panel which is ejected during the evacuation of gas, following an inadvertent ignition.
Les dispositifs de fermeture rappelés ci-dessus présentent les inconvénients inhérents à leur structure.The closing devices mentioned above have the drawbacks inherent in their structure.
En effet, ils sont lourds et ne peuvent être actionnés qu'au moyen d'un système de motorisation qui non seulement nécessite une place importante dans le module de lancement mais alourdit considérablement la structure dudit module de lancement sur le pont. De plus, chaque module de lancement nécessite son propre système de motorisation des portes ce qui réduit la place disponible sur le bâtiment.Indeed, they are heavy and can only be actuated by means of a motorization system which not only requires an important place in the launch module but considerably increases the structure of said launch module on the bridge. In addition, each launch module requires its own door operator system which reduces the space available on the building.
Enfin, et ceci constitue également un très grave inconvénient, l'éjection du panneau éjectable constitue un véritable projectile qui peut provoquer, par la chute des dommages importants tant humains que matériels.Finally, and this also constitutes a very serious drawback, the ejection of the ejectable panel constitutes a real projectile which can cause, by the fall, significant damage both human and material.
Dans une demande distincte, il est proposé de substituer à une cheminée unique d'évacuation des gaz de propulsion, un système d'évacuation constitué par plusieurs conduits d'évacuation distincts débouchant par les extrémités inférieures dans un plénum ou chambre de tranquillisation. Le fait d'utiliser des conduits d'évacuation distincts a permis d'étudier et de concevoir de nouveaux dispositifs de fermeture qui soient appliqués aux conduits d'évacuation distincts, il va de soi qu'ils peuvent être utilisés pour des systèmes d'évacuation à cheminée unique.In a separate application, it is proposed to substitute for a single chimney for discharging the propellant gases, an exhaust system constituted by several separate exhaust conduits opening out through the lower ends into a plenum or stilling chamber. The fact of using separate exhaust ducts has made it possible to study and design new closure devices which are applied to separate exhaust ducts, it goes without saying that they can be used for exhaust systems with single chimney.
La présente invention a pour but un dispositif de fermeture et de protection d'un système d'évacuation de gaz qui soit simple dans sa construction et qui nécessite aucun moyen de motorisation pour manoeuvrer le dispositif de fermeture.The object of the present invention is a device for closing and protecting a gas evacuation system which is simple in its construction and which requires no motor means to operate the closing device.
La présente invention a pour objet un dispositif de fermeture et de protection qui comprend au moins un élément de fermeture monté sur un axe de pivotement traversant un support qui est disposé autour et près de l'extrémité supérieure du conduit d'évacuation des gaz.The subject of the present invention is a closure and protection device which comprises at least one closure element mounted on a pivot axis passing through a support which is arranged around and near the upper end of the exhaust gas duct.
Un avantage de la présente invention réside dans le fait que l'élément de fermeture est ouvert par la seule pression des gaz de propulsion.An advantage of the present invention lies in the fact that the closure element is opened by the sole pressure of the propellant gases.
Selon une autre caractéristique, l'élément de fermeture est rappelé vers la position de fermeture par un organe de rappel et il est disposé dans un élément de protection ce qui permet, d'une part, d'éviter le montage d'une pièce éjectable et non récupérable susceptible d'occasionner des dommages corporels et matériels et, d'autre part, d'assurer une protection du ou des conduits d'évacuation des gaz, en empêchant que l'eau de mer ou des objets solides ne pénètrent à l'intérieur desdits conduits d'évacuation.According to another characteristic, the closing element is returned to the closed position by a return member and it is arranged in a protective element which makes it possible, on the one hand, to avoid the mounting of an ejectable part and non-recoverable likely to cause personal injury and material damage and, on the other hand, to ensure protection of the gas evacuation pipe or pipes, by preventing sea water or solid objects from entering the inside said evacuation conduits.

Le module de lancement vertical, représenté sur la figure 1 comprend une structure 1 dans laquelle sont ménagées des alvéoles 2 de réception de missiles, non représentées, les alvéoles 2 débouchant dans une plaque supérieure 3 par des ouvertures supérieures 4 et dans une plauque inférieure 5 par des passages 6.The vertical launch module, shown in Figure 1 comprises a
Les passages 6 communiquent avec un plénum ou chambre de tranquillisation 7 qui occupe la majeure partie de la base 8 de la structure 1.The
Le dispositif d'évacuation des gaz de propulsion des missiles est constitué dans l'exemple représenté sur la figure 1 par quatre conduits distincts 9, de préférence de forme cylindrique, et qui sont disposés entre les plaques supérieure et inférieure 3 et 5, d'une part, et entre les passages 6, d'autre part, de manière à occuper le volume du module délimité par les alvéoles.The device for discharging the missile propulsion gases consists, in the example shown in FIG. 1, of four
Chaque conduit d'évacuation 9 est équipé d'un dispositif de fermeture et de protection 10, ainsi que cela est représenté sur la figure 1.Each
Chaque dispositif 10 est monté sur la plaque supérieure 3 du module de lancement vertical et autour de l'extrémité supérieure 9′ du conduit d'évacuation qui lui est associé.Each
Le dispositif 10 comprend un élément de fermeture constitué par un manchon 11 dont le bord supérieur 11′ est situé au-dessus du bord libre du conduit d'évacuation 9, et deux clapets 12 montés à pivotement sur un axe 13 traversant le corps du manchon 11. L'axe de pivotement 13 est disposé de telle façon que les clapets 12, dans la position de fermeture, représentée sur la figure 2 en pointillés, viennent en appui sur le bord supérieure 11′ du manchon porte-clapets 11. Le manchon porte-clapets 11 est fixé par sa base 11˝ sur la plaque supérieure 3, par tout moyen approprié tel que des boulons 14 (figure 4 et 6).The
Un élément de protection 15 est disposé autour du manchon porte-clapets 11, et il est monté et fixé sur ce dernier au moyen de pattes ou d'une couronne interne s'appliquant sur la base 11˝ du manchon porte-clapets 11, et des boulons 14, avec interposition d'un joint d'étanchéité 19 ainsi que cela est représenté sur la figure 6.A
L'élément de protection 15 qui, en section, est elliptique comporte un bord supérieur libre 15′ qui se trouve au-dessus du bord supérieur 11′ du porte-clapets 11. Deux orifices d'évacuation 16 sont ménagés à la base des corps de l'élément de protection 15 et au-dessous du niveau des clapets 12. De cette manière, les clapets 12 sont protégés de l'action des paquets d'eau de mer susceptibles de balayer le pont du bâtiment , l'eau de mer étant évacuée par les orifices 16. De plus, à l'ouverture des clapets 12 et grâce à la différence de niveau des bords supérieurs 11′ et 15′ respectivement du manchon porte-clapet 11 et de l'élément de protection 15, les gaz de propulsion ne peuvent s'évacuer latéralement.The
Un ressort de rappel ou tout autre moyen équivalent tel qu'une ou des barres de torsion 17, rappellent mécaniquement les clapets vers la position de fermeture dès que la pression des gaz de propulsion s'appliquant sur les clapets 12 est inférieure au tarage du ressort ou au moment de torsion des barres de torsion. Le rappel mécanique utilisé est calculé de façon qu'il ne soit pas trop important ; faute de quoi la pression des gaz nécessaire pour ouvrir les clapets 12 serait trop élevée et conduirait à un alourdissement général. Il faut noter que même avec un rappel mécanique, relativement faible, les clapets 12 ne sont pas sensibles aux paquets d'eau de mer grâce à la présente de l'élément de protection 15.A return spring or any other equivalent means such as one or
Bien entendu, la nature des matériaux utilisés pour les divers éléments constitutifs du dispositif selon l'invention sont choisis de façon à résister aux actions corrodantes de l'eau de mer et des gaz de propulsion, s'évacuant à travers les conduits d'évacuation.Of course, the nature of the materials used for the various constituent elements of the device according to the invention are chosen so as to resist the corroding actions of sea water and propellant gases, evacuating through the evacuation conduits .
Lors d'un tir ou d'un allumage intempestif d'un missile, la pression des gaz de propulsion 18 régnant dans chaque conduit 9 provoque l'ouverture des clapets 12, à l'encontre du rappel mécanique, pour les amener dans la position où ils sont dos à dos, comme cela est représenté sur la figure 2. Les gaz de propulsion 18 s'évacuent en majeure partie vers le haut et dans l'atmosphère et ce, grâce à la présence de l'élément de protection qui agit comme un élément de guidage desdits gaz de propulsion. Une évacuation latérale important pourrait être préjudiciable pour le missile tiré.When a missile is fired or inadvertently ignited, the pressure of the
Lorsque la pression des gaz de propulsion est inférieure au rappel mécanique, ce dernier ramène les clapets 12 dans leur position de fermeture.When the pressure of the propellant gases is lower than the mechanical return, the latter returns the
Le dispositif selon l'invention, enfin, s'accomode des variations de positions relatives des conduits d'évacuation 9 et de la plaque supérieure 3 puisqu'il s'adapte uniquement sur les conduits d'évacuation quel que soit leur emplacement dans la plaque supérieure 3 du module de lancement vertical.Finally, the device according to the invention accommodates variations in the relative positions of the
