Abstract: The present invention relates to a penetration assistance kit fitted to a bomb, notably an anti-infrastructure bomb. The kit includes launch tubes mechanically secured to the bomb. In each of the launch tubes is positioned a detonating projectile and its propulsive charge. A detonating projectile can be ejected from its tube by initiation of its propulsive charge. A system is provided for controlling the initiation of each propulsive charge prior to impact of the bomb with a target. The invention applies notably to the penetration of very thick walls made of non-metallic material such as concrete, for example. The invention also relates to a penetrating projectile equipped with such a kit and to a method of getting such a projectile to penetrate a target.

Abstract: Disclosed is a device used to bend the end of the trajectory of a rocket in the desired plane without making costly and complicated servo-control mechanisms necessary. A cardan type assembly is formed by a section of the projectile and an internal frame, a gyrostat being mounted in the internal frame. The section carries the control instrument. The device can thus be used to keep the control instrument in a stable roll position throughout the trajectory. It is thus possible to bend the trajectory in a defined direction so as to attack targets from the top with high precision. The device can be adapted to infantry rockets, aeronautical rockets and in general, to short-range projectiles.
