Description

Domaine techniqueTechnical area

L'invention concerne une tête de visée équipant un aéronef tel qu'un giravion. Plus précisément, l'invention a pour objet une tête de visée équipée d'un pointeur laser intégré permettant l'illumination d'une cible par un faisceau laser émettant des rayonnements dans les domaines visible ou proche infra rouge.The invention relates to an aiming head equipping an aircraft such as a rotorcraft. More specifically, the subject of the invention is a sighting head equipped with an integrated laser pointer allowing the illumination of a target by a laser beam emitting radiation in the visible or near infrared.

L'invention s'applique notamment à une tête de visée d'une conduite de tir d'hélicoptère.The invention applies in particular to a head of sighting of a helicopter fire control.

Etat de la techniqueState of the art

Il est connu d'équiper les hélicoptères militaires d'une conduite de tir comportant une tête de visée. Plus précisément, la tête de visée comprend un boítier dont la majeure partie est généralement située au-dessus du toit de la cellule de l'hélicoptère. Un bras porte oculaire prolonge la tête de visée à l'intérieur de la cellule.It is known to equip helicopters soldiers of a fire control system with a referred. More specifically, the aiming head comprises a most of which is generally located above the roof of the helicopter's cell. A eyepiece arm extends the aiming head to inside the cell.

Dans certaines conditions d'utilisation, il est nécessaire d'illuminer la cible par un faisceau laser. Selon que l'utilisateur observe la cible à l'oeil nu ou au moyen de jumelles de vision nocturne, on utilise un faisceau laser émettant dans le domaine visible ou dans le domaine du proche infra rouge.Under certain conditions of use, it is necessary to illuminate the target with a beam laser. Depending on whether the user observes the target by eye naked or using night vision goggles, uses a laser beam emitting in the field visible or in the near infrared domain.

Actuellement, l'illumination de la cible est alors assurée par un appareil appelé "pointeur laser". Plus précisément, cet appareil est tenu à la main, à l'extérieur de l'hélicoptère. En effet, la cellule de l'hélicoptère entraínerait une forte atténuation des fréquences laser et provoquerait des réflexions internes préjudiciables si le pointeur laser était utilisé à l'intérieur de l'hélicoptère.Currently, target illumination is then provided by a device called "laser pointer". More specifically, this device is held by hand, outside the helicopter. Indeed, the cell of the helicopter would significantly reduce laser frequencies and would cause reflections harmful internal if the laser pointer was used inside the helicopter.

Du fait de leur caractère manuel et de leur utilisation à l'extérieur de l'hélicoptère, les pointeurs laser existants ne permettent pas un pointage précis. La portée d'utilisation s'en trouve réduite.Because of their manual nature and their use outside of the helicopter, existing laser pointers do not allow pointing specific. The range of use is reduced.

Le document FR-A-2 640 037 concerne un viseur de mât d'hélicoptère équipé d'un télémètre ou d'une barrière photoélectrique à laser, qui regarde à travers les pales du rotor. Cet agencement permet de prendre en compte l'instant du passage de la pale du rotor pendant le processus d'alignement entre le viseur et le système autodirecteur d'un missile.Document FR-A-2 640 037 relates to a viewfinder helicopter mast equipped with a rangefinder or laser light barrier, which looks through the rotor blades. This arrangement makes it possible to take into counts the moment the rotor blade passes during the alignment process between the viewfinder and the system missile seeker.

Exposé de l'inventionStatement of the invention

L'invention a précisément pour objet une tête de visée équipée d'un pointeur laser intégré permettant d'assurer une précision de pointage et une portée d'utilisation optimales, sans dégrader les caractéristiques propres de la tête de visée.The subject of the invention is precisely a head sight equipped with an integrated laser pointer allowing ensure pointing accuracy and range of optimal use, without degrading the specific characteristics of the aiming head.

De façon plus précise, l'invention concerne une tête de visée pour giravion, comprenant un boítier dont au moins une partie est apte à être située à l'extérieur d'une cellule du giravion, caractérisée en ce qu'un pointeur laser est intégré à la tête de visée, dans ladite partie du boítier.More specifically, the invention relates an aiming head for rotorcraft, comprising a housing at least part of which is suitable for being located the exterior of a rotorcraft cell, characterized by that a laser pointer is integrated into the aiming head, in said part of the housing.

De préférence, la partie du boítier située à l'extérieur de la cellule est délimitée vers l'extérieur de la tête de visée par un capotage aérodynamique existant de celle-ci. Ainsi, le comportement aérodynamique de la tête de visée n'est pas modifié par l'intégration du pointeur laser.Preferably, the part of the housing located at the outside of the cell is bounded towards the outside of the sighting head by a cowling existing aerodynamics thereof. So the aerodynamic behavior of the aiming head is not modified by the integration of the laser pointer.

Avantageusement, le pointeur laser comprend un émetteur laser et des moyens de réglage d'orientation de celui-ci dans ladite partie du boítier, permettant de rendre un faisceau laser émis par le pointeur laser parallèle à un axe de visée de la tête de visée. Il est ainsi possible de régler avec précision le parallélisme du faisceau laser et de l'axe de la tête de visée.Advantageously, the laser pointer comprises a laser transmitter and orientation adjustment means of it in said part of the housing, allowing to render a laser beam emitted by the laser pointer parallel to an aiming axis of the aiming head. It is thus possible to precisely adjust the parallelism of the laser beam and the axis of the aiming head.

Dans ce cas, les moyens de réglage d'orientation comprennent de préférence trois vis de réglage régulièrement réparties autour de l'émetteur laser.In this case, the adjusting means preferably include three screws setting regularly distributed around the transmitter laser.

Par ailleurs, le pointeur laser comprend de plus une source d'énergie propre à l'émetteur laser et un récepteur radio permettant l'allumage et l'extinction de l'émetteur laser.Furthermore, the laser pointer includes plus a clean power source for the laser transmitter and a radio receiver allowing the ignition and switching off the laser transmitter.

A preferred embodiment of the invention will now be described, by way of illustrative and in no way limitative, with reference to the appended drawings, in which:
  • Figure 1 is a side view, which schematically shows the front part of a helicopter equipped with a sighting head incorporating a laser pointer, according to the invention;

Description détaillée d'un mode de réalisation préféré de l'inventionDetailed description of a preferred embodiment of the invention

Sur la figure 1, on a représenté schématiquement la partie avant d'un hélicoptère. Celui-ci comporte une cellule 10 dont le toit supporte une tête de visée 12 d'une conduite de tir (non représentée).In Figure 1, there is shown schematically the front part of a helicopter. This includes a cell 10 whose roof supports a sighting head 12 of a firing line (not shown).

La tête de visée 12 comprend un boítier 14 dont une partie principale 16 est située au-dessus du toit de la cellule 10, à l'extérieur de l'hélicoptère. Une autre partie 18 du boítier 14 est située à l'intérieur de la cabine de pilotage 20 de l'hélicoptère. Un bras porte oculaire 22 terminé par un oculaire 24 est monté sur la partie 18 du boítier 14, pour permettre à un observateur placé dans la cabine 20 d'utiliser la tête de visée 12.The sighting head 12 comprises a housing 14 of which a main part 16 is situated above the roof of cell 10, outside the helicopter. Another part 18 of the housing 14 is located at inside the cockpit 20 of the helicopter. An eyepiece arm 22 terminated by a eyepiece 24 is mounted on the part 18 of the housing 14, to allow an observer placed in cabin 20 to use the aiming head 12.

Les parties 16 et 18 du boítier 14 et le bras porte oculaire 22 servent à loger différents composants optiques (non représentés) permettant à un observateur regardant par l'oculaire 24 d'observer une scène selon un axe de visée 26. Seule une lentille de sortie 28, disposée selon cet axe 26, est visible sur la figure 2.Parts 16 and 18 of the housing 14 and the arm eyepiece holder 22 are used to house different components optics (not shown) allowing an observer looking through eyepiece 24 to observe a scene according to a line of sight 26. Only an exit lens 28, arranged along this axis 26, is visible in FIG. 2.

Dans le mode de réalisation illustré sur la figure 2, la partie principale 16 du boítier 14 permet également de loger une caméra 30.In the embodiment illustrated in the Figure 2, the main part 16 of the housing 14 allows also to house a camera 30.

Conformément à l'invention, un pointeur laser 32 est également placé à l'intérieur de la partie principale 16 du boítier 14. According to the invention, a laser pointer 32 is also placed inside the part main 16 of the housing 14.

De façon plus précise et comme l'illustre en particulier la figure 3, le pointeur laser 32 est logé dans une zone de la partie principale 16 du boítier 14, délimitée vers l'extérieur de la tête de visée 12 par un capotage aérodynamique 34 existant. Dans le mode de réalisation représenté sur les figures, la zone dans laquelle est logé le pointeur laser 32 est localisée au-dessus de la caméra 30. Toutefois, cette zone peut être située en tout autre emplacement disponible approprié, selon les caractéristiques propres à la tête de visée dans laquelle son implantation est réalisée.More precisely and as illustrated in in particular in Figure 3, the laser pointer 32 is housed in an area of the main part 16 of the housing 14, bounded towards the outside of the aiming head 12 by an existing aerodynamic cover 34. In the mode of realization shown in the figures, the area in which is housed the laser pointer 32 is located above the camera 30. However, this area can be located in any other available location suitable, according to the characteristics of the head of sight in which its implantation is carried out.

De façon générale, la zone dans laquelle est reçu le pointeur laser 32 est choisie en tenant compte d'un certain nombre de critères tels que le confort d'utilisation pour l'opérateur, l'existence d'un volume suffisant pour permettre l'implantation des différents organes constituant le pointeur laser, l'existence de possibilités d'accrochage garantissant une bonne rigidité, la facilité d'accès pour la maintenance et le respect de la géométrie extérieure de la tête de visée.In general, the area in which is received the laser pointer 32 is chosen taking into account of a number of criteria such as comfort of use for the operator, the existence of a volume sufficient to allow the establishment of different organs making up the laser pointer, the existence of hanging possibilities guaranteeing good rigidity, ease of access for maintenance and respect of the outside geometry of the aiming head.

Le pointeur laser 32 comprend essentiellement un émetteur laser 36, une source d'énergie 38 propre à cet émetteur et un récepteur radio 40.The laser pointer 32 essentially comprises a laser transmitter 36, an energy source 38 suitable for this transmitter and a radio receiver 40.

L'émetteur laser 36 est, par exemple, une diode émettrice laser apte à émettre un faisceau laser dans le domaine du visible ou dans le domaine du proche infra rouge, selon que l'observateur regarde la scène à l'oeil nu ou à l'aide de lunettes de visée nocturnes.The laser transmitter 36 is, for example, a laser emitting diode capable of emitting a laser beam in the visible or near domain infrared, depending on whether the observer watches the scene from with the naked eye or with night vision goggles.

L'émetteur laser 36 est monté sur un support de référence 42, fixé à l'intérieur de la partie 16 du boítier 14, par exemple au moyen de vis 43. Plus précisément, l'émetteur laser 36 est monté sur le support 42 par l'intermédiaire de moyens 44 de réglage d'orientation. Lesdits moyens 44 de réglage d'orientation ont pour fonction de permettre un réglage précis du parallélisme du faisceau laser susceptible d'être émis par l'émetteur laser 36 vis-à-vis de l'axe de visée 26 de la tête de visée 12.The laser transmitter 36 is mounted on a support 42, fixed inside part 16 of the housing 14, for example by means of screws 43. More precisely, the laser transmitter 36 is mounted on the support 42 by means of adjustment 44 orientation. Said adjustment means 44 have the function of allowing adjustment precise parallelism of the laser beam likely to be emitted by the laser transmitter 36 with respect to the axis sight 26 of the sight head 12.

Dans le mode de réalisation préféré de l'invention illustré sur la figure 3, les moyens 44 de réglage d'orientation comprennent trois vis de réglage 46, orientées parallèlement à l'axe de l'émetteur laser 36 et régulièrement réparties autour de cet axe.In the preferred embodiment of the invention illustrated in FIG. 3, the means 44 of orientation adjustment include three adjustment screws 46, oriented parallel to the axis of the laser transmitter 36 and regularly distributed around this axis.

De façon plus précise, une partie avant de l'émetteur laser 36 est fixé sur une platine 48, à l'avant du support 42, et il traverse une ouverture 49 usinée dans ledit support. Par ailleurs, les vis 46 traversent librement des trous 50 et 52 formés respectivement dans le support 42 et dans la platine 48, et elles sont vissées dans des écrous 54, à l'avant de la platine 48. Des ressorts hélicoïdaux de compression 56, montés sur chacune des vis 46 entre le support 42 et la platine 48, maintiennent en permanence ces deux pièces éloignées l'une de l'autre.More specifically, a front part of the laser transmitter 36 is fixed to a plate 48, at the front of the support 42, and it passes through an opening 49 machined in said support. By the way, the screws 46 freely pass through holes 50 and 52 formed respectively in the support 42 and in the plate 48, and they are screwed into nuts 54, at the front of plate 48. Coil springs of compression 56, mounted on each of the screws 46 between the support 42 and plate 48, permanently maintain these two rooms distant from each other.

Lorsque le capotage aérodynamique 34 est en place, c'est-à-dire lorsqu'il est fixé sur la partie principale 16 du boítier 14, par exemple au moyen de vis (non représentées), l'extrémité avant de l'émetteur laser 36 se trouve en face d'une ouverture 58 formée dans ledit capotage et chacun des boulons 54 se trouve en face d'un trou 60 percé dans le capotage 34.When the aerodynamic rollover 34 is in place, i.e. when it is fixed on the part main 16 of the housing 14, for example by means of screws (not shown), the front end of the transmitter laser 36 is located opposite an opening 58 formed in said cowling and each of the bolts 54 is located opposite a hole 60 drilled in the cowling 34.

Il est ainsi possible de régler le parallélisme du faisceau laser émis par le laser, vis-à-vis de l'axe de visée 26, en introduisant un outil tel qu'une clef dans les trous 60, pour agir sur les écrous 54. En effet, une rotation de l'un quelconque des écrous 54 dans l'un ou l'autre sens, commandée par l'outil précité, a pour effet de comprimer ou d'allonger le ressort 56 monté sur la vis 46 en prise sur cet écrou. On commande ainsi un rapprochement ou, au contraire, un éloignement de la platine 48 vis-à-vis du support 42, en face de la vis 46 considérée.It is thus possible to adjust the parallelism of the laser beam emitted by the laser, opposite of the line of sight 26, by introducing a tool such as a key in the holes 60, to act on the nuts 54. Indeed, a rotation of any one nuts 54 in either direction, controlled by the aforementioned tool has the effect of compressing or to extend the spring 56 mounted on the screw 46 in engagement on this nut. We thus command a reconciliation or, on the contrary, a distance from the plate 48 vis-à-vis of the support 42, opposite the screw 46 considered.

La source d'énergie 38 est, par exemple, une pile ou une batterie d'alimentation électrique. Elle est placée sous une ouverture du capotage 34, normalement fermée par une trappe 62. La source d'énergie 38 a pour fonction d'alimenter en énergie l'émetteur laser 36 ainsi que le récepteur radio 40.The energy source 38 is, for example, a battery or power supply battery. She is placed under an opening in the cowling 34, normally closed by a hatch 62. The source of energy 38 has the function of supplying energy the laser transmitter 36 and the radio receiver 40.

Enfin, le récepteur radio 40 est connecté électriquement à l'émetteur laser 36 et à la source d'énergie 38 pour permettre l'allumage et l'extinction de l'émetteur laser 36.Finally, the radio receiver 40 is connected electrically to the laser transmitter 36 and to the source of energy 38 to allow switching on and off of the laser transmitter 36.

Bien entendu, l'invention n'est pas limitée au mode de réalisation qui vient d'être décrit à titre d'exemple. Ainsi, comme on l'a déjà indiqué, le pointeur laser peut être implanté sur une tête de visée de conception différente et en un emplacement différent de celui qui a été décrit, sans sortir du cadre de l'invention.Of course, the invention is not limited to embodiment which has just been described as example. Thus, as already indicated, the laser pointer can be installed on an aiming head of different design and in a different location of the one which has been described, without going beyond the framework of the invention.
