METHOD FOR INERTIAL GUIDANCE OF ROLL SHELL Russian patent published in 2016 - IPC F42B15/01 

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to methods of guidance on roll of projectile. For inertial guidance of projectile rotating on roll is measured misalignment between position of longitudinal axis of projectile and position of inertial axis gyro measured angular velocity of projectile in associated with a shell of a rotating roll system of coordinates with respect to two mutually orthogonal transverse projectile axes form a steering actuator control signal when threshold of mismatch is exceeded. Method includes generating additional control signals from angular velocity on ballistic trajectory leg before inertial guidance in excess of angular velocity of projectile thresholds, determined from conditions required to ensure amplitude fluctuations of projectile on angle of attack and slip.

EFFECT: providing angular stabilisation of projectile.
