METHOD CONTROLLING SELF-GUIDED ROTATING PROJECTILE Russian patent published in 2000 - IPC

FIELD: armament, specifically, guided artillery projectiles with self-guidance. SUBSTANCE: given invention can be used in antitank and antiaircraft rockets and controlled mines. Technical objective of invention lies in increased precision of guidance of controlled projectile thanks to damping of vibrations which is achieved by insertion of additional component recurring on frequency of inherent vibrations of projectile and damping these vibrations into control signal proportional to angular velocity of rotation of line " projectile-target". Angular velocity of rotation of line " projectile-target " and change of angular velocity of rotation of velocity vector of projectile in correspondence with control signal u are measured with the aid of self-guidance gyroscopic head. Rotor of self-guidance head is rotated in direction opposite to rotation of projectile by roll and control signal is formed by dependence , where k₁, k₂ are proportionality factors, T_h is time constant of self-guidance head, Δ is angle of longitudinal axis of self-guidance head with longitudinal axis of projectile, u is first derivative of control signal by time. EFFECT: increased guidance precision of controlled projectile. 2 dwg
