Abstract

The weapon carrier is mounted under the support wing (10a) on a bracket (11) with two ends (11a, 11b). It has end slides, each slide along fixed guides (13,14) in the support wing. The sliding fittings allow the weapons carrier to tilt. The tilt axis coincides with the centre of mass. A servo-drive has a ram (16) between the support wing and the carrier frame, and is nearly parallel to one of the fixed guides.

Description

Support d'arme à positionnement réglable pour hélicoptères
La présente invention concerne un support d'arme pivotable pour hélicoptères, à sortir au moyen d'un bras en porte-à-faux et d'un palier pivotable.
Adjustable position weapon support for helicopters
The present invention relates to a pivotable weapon support for helicopters, to be removed by means of a cantilever arm and a pivotable bearing.

De tels supports d'armes sont connus en soi dans diverses formes de réalisation. Par un support dit de charge extérieure, on y oriente le récipient de lancement latéralement à l'hélicoptère et on le met en position de tir. Mais, dans ces réalisations, le centre de rotation et par conséquent la principale force de déplaeementsetrouvent au-dessus du support d'arme. Or, cela exige que les forces de maintien et de dépla- cement du support d'arme soient très élevées et imposent un moment d'inertie et des forces d'accélération également élevés.Le moteur électrique assurant ces déplacements consomme de ce fait une très grande quantité de courant et chauffe beaucoup, comme on l'a constaté dans la pratiquee
D'autre part, ces conditions données requièrent une commande de positionnement lourde et volumineuse avec une forte consommation de puissance.
Such weapon supports are known per se in various embodiments. By a so-called external load support, the launching container is oriented laterally to the helicopter and it is put in the firing position. However, in these embodiments, the center of rotation and therefore the main force of displacements is found above the weapon support. However, this requires that the holding and displacement forces of the weapon support be very high and impose a moment of inertia and also high acceleration forces. The electric motor ensuring these displacements therefore consumes a very large amount of current and heats up a lot, as we have seen in practice
On the other hand, these given conditions require a heavy and bulky positioning command with a high power consumption.

L'invention a pour objet un support d'arme pivotable du genre annoncé dans lequel la charge agissant sur le système de pointage soit considérablement réduite, et les inconvénients précités du niveau de la technique éliminés dans une bonne mesure. The invention relates to a pivotable weapon support of the advertised type in which the load acting on the aiming system is considerably reduced, and the abovementioned drawbacks of the level of the technique eliminated to a good extent.

Ce support d'arme est caractérisé par le fait qu'il dispose de bras supports qui sont articulés sur des paliers linéaires soit à glissement, soit à roulement qui sont établis déplaçables en translation sur des tiges de glissement au moyen dune commande de positionnement. This weapon support is characterized by the fact that it has support arms which are articulated on linear bearings either with sliding, or with rolling which are established displaceable in translation on sliding rods by means of a positioning control.

L'invention sera mieux comprise à l'aide de la description détaillée d'un mode de réalisation pris comme exemple non limitatif et illustré schématiquement, en coupe partielle, par la figure unique du dessin annexé. The invention will be better understood using the detailed description of an embodiment taken as a nonlimiting example and illustrated diagrammatically, in partial section, by the single figure of the appended drawing.

Sur un bras-support de charge extérieure, non représenté, d'un hélicoptère se trouve, de façon connue, un bras pivotant en porte-à-faux 10a auquel est associé un support d'arme 11. On an external load support arm, not shown, of a helicopter is, in known manner, a pivoting cantilever arm 10a with which is associated a weapon support 11.

Ce support d'arme 11 est agenoé et disposé, à l'intérieur de ce bras pivotant 10a, en sorte qu'il comporte des brassupports lia et ltb dont les extrémités supérieures sont munies de paliers linéaires à glissement ou à roulement 15 suspendus mobiles en rotation. Ces paliers 15 se déplacent sur des tiges de glissement 13, 14. Ces tiges de glissement 13, 14 sont de préférence positionnées les unes par rapport aux autres sur le bras pivotant en porte-à-faux 10a d'une façon telle que le centre de rotation M se trouve au centre de gravité du support d'arme 11, avec arme 12 suspendue, dans la-position de repos, ou horizontale, et qu'il reste également dans le plan 17 dudit centre de gravité sous un angle d'inclinaison de l'arme.Ce point est alors désigné par M1 sur le dessin. This weapon support 11 is arranged and arranged, inside this pivoting arm 10a, so that it comprises brassupports lia and ltb, the upper ends of which are provided with linear sliding or rolling bearings 15 movable suspended in rotation. These bearings 15 move on sliding rods 13, 14. These sliding rods 13, 14 are preferably positioned relative to each other on the cantilever pivoting arm 10a in such a way that the center of rotation M is at the center of gravity of the weapon support 11, with the weapon 12 suspended, in the rest position, or horizontal, and that it also remains in the plane 17 of said center of gravity at an angle of tilt of the weapon. This point is then designated by M1 on the drawing.

La commande de positionnement 16 établie dans le bras pivotant 10a est reliée au support d'arme 11 de telle façon que la jambe de force réglable 16b soit articulée sur le support d'arme il en sorte que le point d'articulation P se trouve proche du ou des bras-supports avant 11b et garantisse un parallélisme entre l'axe 16a du cylindre de positionnement et le ou les axes 13a de la ou des tiges de glissement avant. De ces dispositions il résulte que le centre de rotation du support d'arme se trouve constamment au centre de celui-ci. Sous les angles d'inclinaison o( qui en général ne dépassent pas une valeur maximale de 200, le centre de rotation instantané M1 n'abandonnera pas non plus le plan 17 du centre de gravité. The positioning control 16 established in the swivel arm 10a is connected to the weapon support 11 so that the adjustable strut 16b is articulated on the weapon support so that the point of articulation P is close of the front support arm (s) 11b and guarantees parallelism between the axis 16a of the positioning cylinder and the axis (s) 13a of the front sliding rod (s). From these provisions it follows that the center of rotation of the weapon support is constantly in the center thereof. Under the angles of inclination o (which in general do not exceed a maximum value of 200, the instantaneous center of rotation M1 will not either abandon the plane 17 of the center of gravity.

bu lieu d'une suspension en deux points du support d'arme 11, on peut concevoir aussi une suspension en trois points. Dans ce cas, le support d'arme comportera, vu en direction de vol "F", à l'avant deux bras-supports 11b avec paliers linéaires à glissement ou à roulement 15 chaque fois articulés et à l'arrière un bras-support avec le palier correspondant. Cet agencement donne également le moment d'inertie minimal possible. instead of a two-point suspension of the weapon support 11, one can also conceive of a three-point suspension. In this case, the weapon support will comprise, seen in flight direction "F", at the front two support arms 11b with linear sliding or rolling bearings 15 each articulated and at the rear a support arm with the corresponding bearing. This arrangement also gives the minimum possible moment of inertia.

Les mesures selon l'invention permettent de plus une réduction importante des influences perturbatrices des forces de tir ou aérodynamique. Le système de positionnement est réalisable sous un poids et un encombrement notablement réduits et, avant tout, la puissance nécessaire pour les forces de positionnement est considérablement diminuée  The measures according to the invention also allow a significant reduction in the disturbing influences of the firing or aerodynamic forces. The positioning system is achievable under a significantly reduced weight and size and, above all, the power required for the positioning forces is considerably reduced
