Description
La présente invention a pour objet un dispositif de conduite de tir pour canons d'artillerie, en particulier canons auto-moteurs à tourelle tout azimut.The present invention relates to a fire control device for artillery guns, in particular self-propelled guns with all-round turret.
Traditionnellement les matériels d'artillerie tractés, auto-mouvants ou auto-moteurs étaient équipés d'un dispositif de conduite de tir formé essentiellement d'un goniomètre optique monté sur un mécanisme de mise à la verticale comprenant des niveaux à bulles, le goniomètre permettant le réglage des paramètres de tir par visée sur des piquets de repérage.Traditionally, towed, self-moving or self-propelled artillery equipment was equipped with a fire control device essentially formed by an optical goniometer mounted on a vertical setting mechanism comprising bubble levels, the goniometer allowing adjustment of the firing parameters by aiming on locating stakes.
On a récemment proposé de munir les canons auto-moteurs d'un équipement goniométrique comportant une centrale inertielle assurant des fonctions de conservation de cap et de recherche de nord à l'aide d'un système à gyrocompas. Un tel équipement goniométrique permet une mise en batterie plus rapide et un réglage de tir plus précis, sans recours à des visées extérieures ce qui est particulièrement favorable pour le tir de la pièce à une position déterminée, le tir pouvant alors s'effectuer immédiatement dès que sont connues les coordonnées géographiques de la pièce mise en batterie.It has recently been proposed to equip self-propelled guns with goniometric equipment comprising an inertial unit ensuring heading conservation and search for the north functions using a gyrocompass system. Such goniometric equipment allows faster battery setting and more precise firing adjustment, without recourse to external sights which is particularly favorable for firing the part at a determined position, firing can then be carried out immediately from that the geographical coordinates of the part put in battery are known.
Compte-tenu des défaillances toujours possibles de la centrale inertielle il est fortement recommandé et même nécessaire d'adjoindre à celle-ci un goniomètre optique.Given the still possible failures of the inertial unit, it is highly recommended and even necessary to add an optical goniometer to it.
Les montages actuels associant une centrale inertielle et un goniomètre optique dans un canon auto-moteur ne donnent pas satisfaction en raison de l'éloignement et du positionnement relatif de ces deux dispositifs (centrale inertielle en chassis, goniomètre en tourelle) qui imposent des opérations d'harmonisation entre les axes de visée et de tir relativement complexes et longues, et qui surtour, ne permettent que le repérage du nord que par rapport à la direction de la projection de l'axe du canon sur le plan de rotation de la tourelle. Outre ce handicap technique, il en résulte notamment que, si la pièce se trouve en batterie sur le sol en dévers, il n'est pas possible en cas d'utilisation du goniomètre de réaliser automatiquement la corrrection de site rendue nécessaire du fait de la position en cévers .The current assemblies associating an inertial unit and an optical goniometer in a self-propelled gun are not satisfactory because of the remoteness and the relative positioning of these two devices (inertial unit in chassis, goniometer in turret) which impose operations of 'Harmonization between the relatively complex and long sighting and firing axes, and which moreover, only allow the location of the north in relation to the direction of the projection of the axis of the gun on the plane of rotation of the turret. In addition to this technical handicap, it results in particular that, if the part is in battery on the sloping ground, it is not possible in the event of use of the goniometer to automatically carry out the site correction made necessary due to the position in cevers.
Le dispositif de conduite de tir selon l'invention permet au contraire nar des moyens particulièrement simples d'obtenir instantanément l'anale de l'axe du canon avec la direction du nord, tout en assurant une correction automatique de dévers.The fire control device according to the invention on the contrary allows particularly simple means to instantly obtain the anal of the axis of the gun with the direction of the north, while ensuring an automatic tilt correction.
La présente invention a pour objet un dispositif de conduite de tir comprenant une centrale inertielle et un goniomètre optique monté sur un mécanisme de mise à la verticale, caractérisé par le fait que la centrale inertielle et le goniomètre optique sont fixés sur une poutre verticale suspendue par sa partie supérieure à un noeud de cardan placé sur un berceau solidaire de la tourelle de manière que l'axe d'oscillation de l'anneau de cardan représente le faux-canon, une transmission homocinétique à parallèlogramme reliant l'axe d'un tourillon du canon à l'axe d'oscillation de l'anneau de cardan représentant le faux-canon.The present invention relates to a firing control device comprising an inertial unit and an optical goniometer mounted on a vertical setting mechanism, characterized in that the inertial unit and the optical goniometer are fixed on a vertical beam suspended by its upper part to a cardan knot placed on a cradle secured to the turret so that the axis of oscillation of the cardan ring represents the false-barrel, a constant velocity parallelogram transmission connecting the axis of a trunnion from the barrel to the axis of oscillation of the cardan ring representing the false-barrel.
Ainsi l'information du site canon est récupérée sur l'axe perpendiculaire à cet axe d'oscillation de l'anneau de cardan représentant le faux-canon, ce qui permet d'obtenir directement l'angle de site du canon lui-même avec le nord.Thus the information of the cannon site is recovered on the axis perpendicular to this axis of oscillation of the cardan ring representing the false gun, which makes it possible to directly obtain the site angle of the cannon itself with the North.
On comprend que lorsque la pièce se trouve sur un sol en dévers, une simple remise du goniomètre à la verticale modifie l'angle de niveau, de sorte que lorsque le tube monte, cette montée provoque la rotation de l'ensemble de la conduite de tir entraînant un changement de direction de la visée optique avec action sur le site. On réalise ainsi une correction automatique de dévers.It is understood that when the part is on a slope, a simple return of the goniometer to the vertical modifies the level angle, so that when the tube rises, this rise causes the rotation of the whole of the pipe. shooting resulting in a change of direction of the optical sight with action on the site. An automatic tilt correction is thus carried out.
On voit ainsi que cette dispositon particulière offre à tout moment la possibilité d'une vérification précise et rapide des indications de la centrale inertielle par l'intermédiaire du goniomètre optique.It can thus be seen that this particular arrangement offers at all times the possibility of a precise and rapid verification of the indications of the inertial unit by means of the optical goniometer.
La poutre utilisée selon l'invention présente avantageusement une partie supérieure de faible largeur, fixée à l'anneau de cardan, prolongée par une partie inférieure en forme de caisson de dimensions adaptées à celles de la centrale inertielle.The beam used according to the invention advantageously has an upper part of small width, fixed to the cardan ring, extended by a lower part in the form of a box of dimensions adapted to those of the inertial unit.
Le goniomètre est avantageusement solidarisé de la poutre par une fixation de la partie inférieure de la poutre au support du goniomètre.The goniometer is advantageously secured to the beam by fixing the lower part of the beam to the support of the goniometer.
Le montage selon l'invention à l'aide d'une poutre supportant la centrale inertielle et le goniomètre assure en outre que c'est la poutre qui encaisse les chocs consécutifs aux déplacements ainsi la mise en place d'un goniomètre moins résistant et donc plus économique.The assembly according to the invention using a beam supporting the inertial unit and the goniometer further ensures that it is the beam which receives the shocks resulting from the displacements thus the installation of a less resistant goniometer and therefore more economical.
Dans le but de mieux faire comprendre l'invention on va maintenant décrire à titre d'exemple en aucune manière limitatif un mode de réalisation en s6 référant au dessin annexé dans lequel :
- .la figure 1 représente schématiquement en élévation frontale un dispositif selon l'invention ;
- .et la figure 2 est une vue en élévation latérale schématique d'une partie de ce dispositif.
- . Figure 1 shows schematically in front elevation a device according to the invention;
- .and Figure 2 is a schematic side elevational view of a part of this device.
Le dispositif selon l'invention comprerdun goniomètre 1 monté, de préférence de manière démontable, sur un support 2 solidaire d'un mécanisme de mise à la verticale comprenant un plateau supérieur à niveaux 3 destiné à être mis à l'horizontale, un plateau intermédiaire 4 muni de manettes de commande 5 permettant l'orientation et le déplacement dans la ligne de plus grande pente, et un plateau inférieur 6 comportant la commande d'asservissement gisement tourelle 7 et la commande d'asservissement site canon 8.The device according to the
Les informations de gisement et de site pour l'asservissement de la tourelle et du tube sont envoyées par une ligne schématisée en 9.The deposit and site information for the control of the turret and the tube are sent by a line shown schematically at 9.
Le dispositif comporte en outre une centrale inertielle désignée globalement par 10, de type en soi connu, assurant des fonctions de conservation de cap et de recherche de nord, cette centrale inertielle n'étant pas représentée sur la figure 2 pour plus de clarté.The device also includes an inertial unit generally designated by 10, of a type known per se, providing heading conservation and search for north functions, this inertial unit not being shown in FIG. 2 for greater clarity.
Selon l'invention, le goniomètre 1 et la centrale inertielle 10 sont tous deux solidarisés d'une poutre verticale désignée globalement en 11, de section sensiblement en forme de U, cette poutre comportant une partie supérieure 12 de largeur réduite et une partie inférieure 13, qui,comme on le voit le mieux sur la figure 1,définit un caisson pour la réception de la centrale inertielle 10.According to the invention, the
La partie inférieure 13 de la poutre est fixée en 14 (figure 2) au support de goniomètre et sa partie supérieure 12 est fixée en 15 à l'anneau d'un noeud de cardan désigné globalement par 16.The
Le noeud de cardan est monté dans un berceau 17 solidaire de la tourelle, une transmission homocinétique 18 à parallélogramme reliant l'axe 19 du tourillon droit du canon à l'axe d'oscillation 20 de l'anneau de cardan représentant le faux-canon, l'information site-canon étant ainsi récupérée sur l'axe 21 perpendiculaire à l'axe 20 du cardan représentant le faux-canon.The cardan knot is mounted in a
Le goniomètre 1 utilisé selon l'invention peut être plus long que le goniomètres traditionnels, ce goniomètre traversant le noeud de cardan 16.The
On voit encore sur la figure 1 une lunette de tir direct 22, une unité de calcul et de contrôle 23 recevant par la ligne 24 l'information de la centrale inertielle 10, et échangeant par la ligne 25 des informations avec une unité de commande et de visualisation 26. Un boitier d'alimentation tampon 27 est relié par la ligne 28 à l'unité de commande et de visualisation 26 et par la ligne 29 à l'unité de calcul et de contrôle 23. Une liaison 30 est naturellement prévue entre le boitier d'alimentation tampon 27 et l'alimentation principale (non représentée). Pour la clarté du dessin on n'a d'ailleurs représenté qu'une partie des liaisons électriques, d'autres liaisons étant par exemple assurées depuis un boitier électrique pour l'éclairage des différents éléments du dispositif.We can also see in FIG. 1 a
Bien que l'invention ait été décrite en liaison avec un mode de réalisation particulier il est bien évident qu'elle n'y est nullement limitée et qu'on peut lui apporter diverses variantes et modifications sans pour autant sortir ni de son cadre ni de son esprit.Although the invention has been described in connection with a particular embodiment, it is obvious that it is in no way limited thereto and that it can be brought to it in various variants and modifications without however departing from its scope or his mind.
