METHOD CONTROLLING FLIGHT OF SURFACE-TO-SURFACE BALLISTIC SELF-GUIDED ROCKET MISSILE Russian patent published in 2003 - IPC

FIELD: weaponry, ground-support systems of surface-to-surface guided rockets ensuring destruction of targets by ballistic selfguided rocket missiles. SUBSTANCE: in compliance with invention reception of information from homing head is begun at time moment t established before launch of rocket missile by value of start angle θ included between longitudinal axis of rocket missile and plane of horizon as well as by table values of initial velocity of rocket missile, aerodynamic resistance of rocket missile and maximum operation range of homing head to standard target. Inclination angle γ of sighting axis of antenna device of homing head to aiming point is determined prior to launch of rocket missile by configuration of ballistic trajectory of rocket missile, parameters of roll rotation ( stabilization, for instance, for stabilized head compartment ) and time of flight of rocket missile from moment t to termination of self-guidance mode. Start angle θ in its turn is measured on leveled launcher by transmitter of inclination angle aboard rocket missile and/or by transmitter of inclination angle on launcher with subsequent transmission of θ or t aboard rocket missile. Finally, roll stabilization of rocket missile in flight is carried out by information from rocket-borne free gyroscope and by information from homing head sighting contrast reference points on underlying surface. Employment of proposed design is viewed as especially advantageous for variants with roll stabilized head comparment-additionally fitted modules of unguided missiles. It can be predicted that complexes of guided rocket missiles based on this approach can build up most numerous class of so-called light high-accuracy surface-to-surface weapons on nearest future with due account of criterion " cost-efficiency ". EFFECT: increased accuracy of guidance of rocket missile on target. 3 cl, 7 dwg
