Patent number: 4923142Abstract: 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.Type: GrantFiled: November 3, 1988Date of Patent: May 8, 1990Assignee: Thomson-Brandt ArmementsInventors: Didier Creusot, Jean-Pierre Roux

Patent number: 4920887Abstract: Disclosed is a system for the holding of multiple warheads, placed in a missile rotating on its longitudinal axis and dropped in trajectory through an end of the missile. Each stage of the warhead includes at least two distinct parts which have to be separated laterally at the moment of dropping, the missile including a casing inside which the warhead is placed. For each stage, mechanisms to fix the parts at the said stage are arranged so that each stage forms a compact unit so as not to cause major radial stresses against the casing due to the centrifugal force created by the rotating missile. The fixing mechanisms are retractable at the moment when the parts are dropped, by means of inertia blocks that are subjected to the centrifugal force. The invention can be applied to sub-munitions and mortar shells.Type: GrantFiled: June 3, 1988Date of Patent: May 1, 1990Assignee: Thomson-Brandt ArmementsInventors: Jean-Pierre Frehaut, Eric Magnaudet, Jean-Pierre Pineau

Patent number: 4901946Abstract: A system is provided for guidance, by laser beam and pyrotechnic thrusters, of one or a number of carriers such as missiles which are intended to intercept maneuvering targets such as aircraft, helicopters or tanks. Guidance of the carrier is performed partly from the ground by means of a laser beam (beam-rider guidance) which tracks the target and partly by means of pyrotechnic thrusters placed on board the carrier. At each instant, the carrier thus "knows" its position with respect to the ideal flight path provided by the laser beam. The carrier corrects its flight path by triggering a pyrotechnic thruster when its distance with respect to the ideal flight path is greater than a predefined threshold value and when its radial velocity to the ideal path is lower than a predefined threshold.Type: GrantFiled: February 6, 1989Date of Patent: February 20, 1990Assignee: Thomson-Brandt ArmementsInventors: Philippe Arnaud, Marc Bernard

Patent number: 4876963Abstract: The invention relates to bombs intended to be released at a very low altitude so as to damage high mechanical resistance surfaces and more particularly antirunway bombs equipped with a downward or acceleration propulsive unit. Each bomb comprises means for braking and orienting it during its initial fall, so as to position the bomb in a plane activating an upward propulsive unit. These means are formed of at least one parachute placed at the head of the bomb. With the activation position reached, the upward propulsive unit causes the bomb to rise and, during the final fall of said bomb, a downward propulsive unit, placed in front of the upward propulsive unit, accelerates the final fall of the bomb so as to accumulate high kinetic energy at the time of impact on the ground.Type: GrantFiled: August 15, 1988Date of Patent: October 31, 1989Assignee: Thomson-Brandt ArmementsInventor: Jean Deffayet

Patent number: 4867035Abstract: A charge releasable from a carrier, such as a charge having to be activated at the moment of release, is provided with an activating device with a safety system to prevent its untimely activation. The triggering means are activated by means of the activating device comprising a cable connected to the carrier. At the moment of release, the cable controls the activating device which initiates the triggering means by means of an internal mechanical link. All the elements are placed inside the charge. Moreover, the activating device constitutes a safety device to prevent the activation of the charge so long as it is not released.Type: GrantFiled: August 23, 1988Date of Patent: September 19, 1989Assignee: Thomson-Brandt ArmementsInventors: Jean Boucard, Andre Delaitre, Jean Deliance, Andre Winaver
