OPTOELECTRONIC SYSTEM OF ANTIAIRCRAFT MISSILE COMPLEX Russian patent published in 2001 - IPC

FIELD: military equipment, in particular, short-range antiaircraft missile complexes with an optical control system and radio-controlled guided antiaircraft missile guidance. SUBSTANCE: the optoelectronic system of antiaircraft missile complex has an optical post consisting of a bearing rack, base with a bottom plate and elevation and traverse actuators, and a control unit, thermovision unit with an automatic telecontrol unit, infra-red seeker unit consisting of an optoelectronic sensor and a coordinate discrimination unit. The system also has a command transmitter with an antenna, movable and fixed branches of the waveguide system and waveguide rotational junctions in the vertical and horizontal planes, gyro angle-data transmitter and cable assemblies with sealed outputs to the connectors. The elevation and traverse actuators of the optical post employ contactless torque motors, the stator of the first of them is secured inside the rack for rotation of the rotor with the shaft in the vertical plane, and the stator of the second torque motor is secured inside the base for rotation of the rotor with the shaft in the horizontal plane. The optical post comprises a high-precision bearing, whose fixed section mounts the base, and secured in the bearing movable section is the shaft of the traversing torque motor rotor. Made in the shaft of the elevation torque motor on the ends are flanges carrying the optoelectronic sensor of the infra- red seeker unit and the thermovision unit, with the gyro angle-data transmitter rigidly attached to its horizontal plane. The antenna is fastened to the shaft of the rotor of the elevation torque motor between the optoelectronic sensor and the thermovision unit. The shafts are made hollow for passage of the branches of the waveguide system with rotational junctions and cable assemblies, which at the outlet of the hollow shaft are assembled in spiral flat bunched conductors; the bunched conductors rotating in the vertical plane are laid in the flanged junctions of the shaft of the rotor of the elevation torque motor. The bunched conductors rotating in the horizontal plane are laid in the base bottom plate, which is made of material with a low friction coefficient; the rotor shaft of the elevation torque motor has a groove in which the movable branch of the waveguide system connected to the antenna is fixed. EFFECT: enhanced efficiency of the complex due to enhanced accuracy of target and missile tracking within a wide range of elevation and traverse angles, reduced mass and dimensional characteristics of the optoelectronic control system. 2 dwg
