Abstract

The invention relates to a sound detecting system for equipping and guiding missiles. The sound detector system 5 is composed of a sound sensor 6 which receives the noise 4 emitted by the target. The noise 4 is decoded 7 then compared to the noises stored in memory 8. In the case of positive recognition, the sound sensor 6 may modify the trajectory of the missile by acting on the rudder commands 1, 3, 9, 12 on the movable fin 15 or on the turbine. The whole of the system 5 will be made up of electronic or mechanical components and/or of chemical elements including a clock 10, a programmer 17, a self-destruct for the system 13, a supply 11, a controller 16, a top-up motor 14. The device according to the invention is particularly intended for equipping missiles for protecting and destroying targets.

Description

La présente invention concerne l'adjonction à un m-issile d'un appareil détecteur de bruit d'hélicoptère et ou toutes autres cibles éventuelles en vue de reconnaitre et de détruire l'hélicoptére et ou toute autre cible grâce à leur bruit caractéristi -que. The present invention relates to the addition to a m-issile of a helicopter noise detection device and or any other possible targets in order to recognize and destroy the helicopter and or any other target thanks to their characteristic noise. .

Actuellement ,les engins aériens ou terrestres sont détruits en particulier par des missiles à détecteur thermique ou détec -teur infra-rouge. Currently, air or land vehicles are destroyed in particular by missiles with thermal detectors or infrared detectors.

I1 existe un inconvénient à ce système,car lorsqu'on lance de l'hélicoptère ou de la ou des cibles,un produit très inflamma -ble et dégageant une grande quantité de chaleur,le missile sui -vra la trajectoire du projectile inflammable et sera donc dévi -é inévitablement de sa cible. There is a drawback to this system, because when one launches from the helicopter or from the target (s), a very inflammable product and giving off a large amount of heat, the missile will follow the trajectory of the flammable projectile and will therefore inevitably deviated from its target.

Avec le systéme de reconnaissance par le bruit,décrit par la présente invention,le missile équipé du dit système,suivra sa cible en reconnaissant le bruit particulier émis par celle-ci, comme le bruit de l'hélice d'un hélicoptére,ou bruit de moteur ou bruit de l'eau ou tout autre bruit suivant que la cible con -sidérée est respectivement un hélicoptére,un avion,un char,un. With the noise recognition system, described by the present invention, the missile equipped with said system, will follow its target by recognizing the particular noise emitted by it, such as the noise of the propeller of a helicopter, or noise engine or noise of water or any other noise depending on whether the target under consideration is respectively a helicopter, an airplane, a tank, a.

bateau ou toutes autres cibles.boat or any other target.

Ainsi,le missile équipé du système,pourra abattre sa cible gr âce à une combinaison de moyens particulièrement simples instal -lés sur le missile. Thus, the missile equipped with the system will be able to shoot down its target thanks to a combination of particularly simple means installed on the missile.

A titre d'exemple non limitatif,une forme d'éxécution de la présente invention est représentée figure l,planche 1. By way of nonlimiting example, an embodiment of the present invention is shown in FIG. 1, plate 1.

La figure 1 est un schéma simplifié d'une installation du sys -tème détecteur de son (5),selon l'invention sur la tête d'un missile.Le système est rattaché au missile par la zone d'articu -lation(2).Le missile sera lancé traditionnellement vers l'obje -ctif à détruire puis le capteur de son (6) reçoit le bruit (4) émis par le moteur et ou l'hélice et ou les pales de la cible. FIG. 1 is a simplified diagram of an installation of the sound detector system (5), according to the invention, on the head of a missile. The system is attached to the missile by the articulation zone (2 The missile will be launched traditionally towards the object -ctive to destroy then the sound sensor (6) receives the noise (4) emitted by the engine and or the propeller and or the blades of the target.

Ensuite le bruit est décodé (7) puis comparé aux bruits stoqués en mémoire dans le comparateur-reconnaisseur de bruit (8),bruits caractérisants les différentes cibles à atteindre.Les bruits des différentes cibles à atteindre auront été préablement analysés et codés.Then the noise is decoded (7) then compared to the noises stored in memory in the noise comparator-recognizer (8), noises characterizing the different targets to be reached. The noises of the different targets to be reached will have been previously analyzed and coded.

En cas de reconnaissance positive (8),le capteur de son (6) pourra modifier la trajectoire du missile en agissant sur le qouvernail (l)1sur les commandes du gouvernail (3 (9)1(12)1sur

la ou les ailettes mobiles (153/de manière à diriger la tête du missile vers la cible afin de détruire celle-ci.In the event of positive recognition (8), the sound sensor (6) can modify the trajectory of the missile by acting on the rudder (l) 1 on the rudder controls (3 (9) 1 (12) 1 on

the movable fin (s) (153 / so as to direct the head of the missile towards the target in order to destroy the latter.

Le capteur de son (6) sera constitué de pièces électroniques et ou mécaniques et ou d'éléments chimiques.Chaque missile pour -ra avoir un code différent (17) ou plusieurs codes selon les cibles recherchées.Au moment du lancement,le code sera mis en fonction par l'utilisateur grâce au programmateur (17).Les co -des pourront être enregistrés électroniquement. The sound sensor (6) will consist of electronic and / or mechanical parts and or chemical elements. Each missile may have a different code (17) or more codes depending on the targets sought. At the time of launch, the code will be activated by the user using the programmer (17). The codes can be saved electronically.

Si le but n'est pas atteint au bout d'un temps déterminé (10) par l'horloge de bord (10),la tête du missile sera détruite au -tomatiquement(13) ainsi que toute la partie électronique rela -tive au système (5). If the goal is not reached after a time determined (10) by the on-board clock (10), the head of the missile will be destroyed at -tomatically (13) as well as all the electronic part relating to system (5).

L'alimentation (11) du système (5) pourra être constitué de piles ou autres énergies physiques,et ou chimiques et ou mécano -ques. The power supply (11) of the system (5) may consist of batteries or other physical, and or chemical and or mechanical energy.

L'ensemble du systàme détecteur de son (5) comprendra égalem -ent un contrôleur du système (16) et un moteur d'appoint (14). The entire sound detector system (5) will also include a system controller (16) and a booster motor (14).

Le dispositif selon l'invention est particulièrement destiné à l'équipement des missiles qui pourront munis du dispositif re -connaitre,détecter et détruire les cibles grâce aux bruits qu' elles émettent. The device according to the invention is particularly intended for equipping missiles which may be provided with the device to recognize, detect and destroy targets thanks to the noises which they emit.
