Title: Method for hitting of military-purpose space objects
Inventor: KOCHETKOV B F
IPC: F42B12/56
Filed: 2000-02-14
Granted: 2001-04-27
Abstract: FIELD: projectiles with a warhead for dispersion of separate solid components, applicable for hitting of warheads of ballistic missiles and space orbital objects of enemy antimissile objects. SUBSTANCE: hitting components in the form of detached particles are injected to the near-earth orbit, and the mentioned space objects are hitted at a collision with the hitting components. Self-destruction of the hitting components is ensured within the estimated time of their existence in the orbit. To this end, they are manufactured of a substance that can evaporate and sublimate in the space. Solar energy is used as sublimation heat. The hitting components are uniformly dispersed in a limited space in the orbit. The vessel with the hitting components is set in spin at it its injection to the orbit, and a momentum of centrifugal force of a various value is imparted to the hitting components at an outlet from the vessel, which depends on the arrangement of each hitting component from the vessel spin axis. Movement of the hitting components is accomplished towards the space object to be hitted, and hitting of own launch vehicles and warheads is prevented at their movement in the same direction with the hitting components towards the enemy at an approximately similar speed. EFFECT: enhanced reliability of hitting of enemy space objects and prevented fouling of space by hitting components. 2 cl
