Description
1 ARME MICRO-ONDE EMBARQUEE Domaine technique et art antérieur L'invention1 MICROWAVE ARMED ONBOARD Technical field and prior art The invention
concerne une arme micro-onde mono- coup. L'invention s'applique aux armes de forte puissance embarquées dans un vecteur de type missile ou obus. Elle concerne les dispositifs mono-coup pour lesquels une efficacité optimale est obtenue par un compromis entre la masse, le volume et la puissance micro-onde rayonnée. Selon l'art connu, les contraintes de volume et de masse conduisent à utiliser comme tube micro-onde, des tubes dont le rendement de conversion entre la puissance électrique et la puissance hyperfréquence est faible (typiquement quelques pour cent). C'est le cas par exemple des vircators. Le choix de la source d'alimentation électrique se porte alors vers les générateurs électropyrotechniques associés, dans certains cas, à un étage d'amplification de puissance de type fusible. La figure 1 représente une arme micro-onde selon l'art connu utilisant une telle source d'alimentation. L'arme micro-onde comprend une inductance 1 entourant un explosif 4, un transformateur ayant un primaire 2 et un secondaire 3, une inductance de stockage 6, un fusible 9 et un tube micro-onde 10 ayant une cathode 8. Un générateur électropyrotechnique a une impédance très faible. Le transformateur 2, 3 permet d'adapter cette impédance à celle du tube. Les courants 2906880 2 importants et la faible masse recherchée pour l'ensemble conduisent à réaliser des transformateurs à air (absence de matériaux ferromagnétiques). Ce type de transformateur a comme caractéristique un coefficient 5 de couplage inférieur à 1 et, partant, la présence de pertes. Cela se traduit, à l'extérieur et à l'intérieur du transformateur, par la présence d'un flux magnétique important. La ligne de champ 5 sur la figure 1 représente ce flux magnétique. La ligne de champ 7 10 représente par ailleurs le champ magnétique présent dans le tube micro-onde. Comme cela a été mentionné ci-dessus, le rendement de conversion du tube hyperfréquence est faible, limitant ainsi fortement la puissance 15 hyperfréquence émise. Ceci représente un inconvénient. L'invention ne présente pas cet inconvénient. Exposé de l'invention En effet, l'invention concerne une arme micro- 20 onde mono-coup comprenant un générateur électropyrotechnique, un tube micro-onde et un transformateur destiné à adapter l'impédance du générateur électropyrotechnique à l'impédance du tube. Le tube micro-onde est un tube micro-onde à champ 25 magnétique externe placé à l'intérieur du transformateur de sorte que le champ magnétique externe du tube microonde est réalisé par le champ magnétique créé par le transformateur. Selon une caractéristique supplémentaire, le 30 dispositif comprend un amplificateur de puissance à fil fusible qui entoure le tube micro-onde. concerns a single microwave weapon. The invention applies to high-powered weapons embedded in a vector of the missile or shell type. It concerns single-shot devices for which optimal efficiency is obtained by a compromise between the mass, the volume and the radiated microwave power. According to the known art, the volume and mass constraints lead to use as a microwave tube, tubes whose conversion efficiency between the electrical power and the microwave power is low (typically a few percent). This is the case, for example, with vircators. The choice of the power supply source is then to the electropyrotechnic generators associated, in some cases, to a fuse type power amplification stage. Figure 1 shows a microwave weapon according to the prior art using such a power source. The microwave weapon comprises an inductor 1 surrounding an explosive 4, a transformer having a primary 2 and a secondary 3, a storage inductor 6, a fuse 9 and a microwave tube 10 having a cathode 8. An electropyrotechnic generator has a very low impedance. The transformer 2, 3 makes it possible to adapt this impedance to that of the tube. The large currents 2906880 2 and the low mass sought for the assembly lead to the realization of air transformers (absence of ferromagnetic materials). This type of transformer has as a characteristic a coupling coefficient of less than 1 and hence the presence of losses. This is reflected, outside and inside the transformer, by the presence of a large magnetic flux. The field line 5 in FIG. 1 represents this magnetic flux. Field line 7 also represents the magnetic field present in the microwave tube. As mentioned above, the conversion efficiency of the microwave tube is low, thus greatly limiting the emitted microwave power. This represents a disadvantage. The invention does not have this disadvantage. DESCRIPTION OF THE INVENTION Indeed, the invention relates to a single-shot micro-wave weapon comprising an electropyrotechnic generator, a microwave tube and a transformer intended to adapt the impedance of the electropyrotechnic generator to the impedance of the tube. The microwave tube is an external magnetic field microwave tube placed inside the transformer so that the external magnetic field of the microwave tube is formed by the magnetic field created by the transformer. According to an additional feature, the device comprises a fusible-wire power amplifier that surrounds the microwave tube.
2906880 3 Selon encore une caractéristique supplémentaire, le fil fusible est torsadé de façon à créer un champ magnétique qui contribue au champ magnétique externe du tube.According to yet another characteristic, the fuse wire is twisted so as to create a magnetic field which contributes to the external magnetic field of the tube.
5 Selon encore une caractéristique supplémentaire, le tube micro-onde est fabriqué en alliage du type TA6V. Brève description des figures 10 D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture d'un mode de réalisation préférentiel fait en référence aux figures jointes, parmi lesquelles : la figure 1 représente une arme micro-onde embarquée 15 mono-coup selon l'art antérieur ; - la figure 2 représente une arme micro-onde embarquée mono-coup selon l'invention. Sur toutes les figures, les mêmes repères désignent les mêmes éléments.According to yet another characteristic, the microwave tube is made of TA6V type alloy. BRIEF DESCRIPTION OF THE DRAWINGS Other features and advantages of the invention will appear on reading a preferred embodiment with reference to the attached figures, in which: FIG. 1 represents a mono-shot embedded microwave weapon; according to the prior art; FIG. 2 represents a single-shot on-board microwave weapon according to the invention. In all the figures, the same references designate the same elements.
20 Description détaillée de modes de mise en œuvre de l'invention La figure 1 a été décrite précédemment. Il est donc inutile d'y revenir.Detailed Description of Embodiments of the Invention Figure 1 has been previously described. It is therefore useless to return to it.
25 La figure 2 représente une arme micro-onde embarquée mono-coup selon l'invention. L'arme micro-onde comprend une inductance 1 entourant un explosif 4, un transformateur ayant un primaire 2 et un secondaire 3, une inductance de 30 stockage 6, un fusible 9 et un tube micro-onde 10. Le tube micro-onde 10 est un tube à champ 2906880 4 magnétique externe placé à l'intérieur du transformateur 2, 3 qui adapte le générateur électropyrotechnique au tube. Un tube à champ magnétique externe (magnétron, 5 klystron, BWO, reditron, etc.) possède un rendement élevé, typiquement de l'ordre de 10 à 30%. Il est alors possible d'accroître très sensiblement la puissance émise par l'arme micro-onde. Il est également possible de diminuer la taille de l'arme micro-onde tout en 10 conservant une puissance émise élevée. A puissance équivalente émise, une arme micro-onde selon l'invention peut ainsi occuper un volume très sensiblement réduit par rapport à une arme micro-onde selon l'art antérieur.FIG. 2 represents a single-shot on-board microwave weapon according to the invention. The microwave weapon comprises an inductor 1 surrounding an explosive 4, a transformer having a primary 2 and a secondary 3, a storage inductor 6, a fuse 9 and a microwave tube 10. The microwave tube 10 is an external magnetic field tube 2906880 4 placed inside the transformer 2, 3 which adapts the electropyrotechnic generator to the tube. An external magnetic field tube (magnetron, klystron, BWO, reditron, etc.) has a high efficiency, typically of the order of 10 to 30%. It is then possible to increase very substantially the power emitted by the microwave weapon. It is also possible to decrease the size of the microwave weapon while maintaining a high emitted power. At equivalent power emitted, a microwave weapon according to the invention can thus occupy a very substantially reduced volume compared to a microwave weapon according to the prior art.
15 Le fusible est un fil qui fait partie d'un amplificateur de puissance. Le fil fusible 9 entoure le tube micro-onde 10. Avantageusement, lorsque le fil fusible est torsadé, il permet la création d'un champ magnétique qui contribue au champ magnétique externe du 20 tube. L'utilisation d'alliage du type TA6V pour la réalisation du tube micro-onde 10 permet, grâce à sa très bonne tenue mécanique et à sa grande résistivité, de laisser passer le flux magnétique tout en assurant 25 une très bonne rigidité mécanique.The fuse is a wire that is part of a power amplifier. The fuse wire 9 surrounds the microwave tube 10. Advantageously, when the fuse wire is twisted, it allows the creation of a magnetic field which contributes to the external magnetic field of the tube. The use of alloy TA6V type for the realization of the microwave tube 10 allows, thanks to its very good mechanical strength and high resistivity, to let the magnetic flux pass while ensuring a very good mechanical rigidity.
