Definitions
- the present invention relates to a tilting device applied to a non-gyrating or slowly gyrating munition, provided with a shaped load and tilting on a trajectory to attack a target from above.
- a projectile according to the preamble of claim 1 intended for assaulting targets from above containing modules carrying explosive boosters and formed charges whose axes are coincident with the longitudinal axis of the projectile.
- the impeller bearing modules include an explosive plate located between a thrust plate and an inertia plate. Each module has autonomous operation controlled by its own target detector.
- the present invention aims to overcome these drawbacks using a device intended to generate an impulse on a non-gyrating or slow-gyrating projectile, with a shaped charge and tilting on a trajectory to attack a target from above, of the type comprising several impellers, each of them comprising an explosive plate located between a thrust plate and an inertia plate and having an autonomous operation controlled by its own target detector, these impellers being distributed so as to form a couple, characterized in that the impellers include a shock absorber block arranged facing the thrust plate and in that the impellers constitute two rings situated respectively at the front and at the rear of the projectile, the impellers of the rear crown being arranged in the same meridian planes as those of the front crown, each impeller of a crown having an associated impeller in the other crown, located in the same meridian plane and opposite relative to the longitudinal axis, these two impellers operating simultaneously to cause a tilting torque.
- the firing order of each pair of impellers is given by a target detector located in the same meridian plane and on the same side with respect to the longitudinal axis as the rear impeller.
- the target detector is arranged in a meridian plane forming a dihedral with the meridian plane containing the associated impellers and whose angle between the two planes is determined so as to overcome the angular velocity of the projectile.
- the projectile according to FIG. 1 comprises an envelope 1 extended by a tail unit 2 and enclosing a formed charge 3.
- the process of initiation of the various pyrotechnic functions is triggered by a infrared detection system located at the front of the projectile and composed of six detectors 4 arranged radially and forming an angle of 60 ° between them, transmitting a signal to a central unit 5 responsible for processing the signal by means of appropriate electronics and to communicate it to the tilting module 6 and to the safety and arming device 7 which initiate impellers 8 and 9 respectively and the charge formed 3.
- Figure 2 and Figure 3 show the six infrared detectors 4 and the impellers 9 of the front ring, six in number and arranged at 60 ° .
- These impellers consist of an inertia plate 10, an explosive plate 11 and a thrust plate 12, the mass ratio of the inertia plate and the thrust plate can advantageously be understood between 1 and 2.
- a damping element 13, intended to receive the thrust plate after operation of the impeller is placed inside the crown, opposite said plate.
- the material constituting the damping element must have an elastic compressive strength of less than 30 hbar, it may be a material such as, for example, low-alloy aluminum, wood, a composite, organic or plastic material.
- a central channel 14 is formed between the damping blocks.
- the initiation of the impellers is carried out by means of the tilting module 6 extended by detonating cords 15 and detonation relays 16.
- Each impeller forms a pair with the rear impeller situated in the same meridian plane and opposite with respect to the longitudinal axis of the projectile. Their operations are simultaneous.
- Figure 3 shows a particular type of embodiment of the impeller ring in which the damping device is in one piece and has a coating 17 at the central channel and its parallel faces.
