IMPULSIVE FREE GYROSCOPE, METHOD FOR ITS STARTING AND METHOD FOR COCKING OF SPIRAL LEAF SPRINGS OF IMPULSIVE FREE GYROSCOPE Russian patent published in 2003 - IPC

FIELD: guided rocketry, in particular, gyroscopes of small-sized guided rockets used as gyro coordinators. SUBSTANCE: gyroscope has a rotor, inner and outer gimbal frame rings, spiral leaf spring, case, attitude sensor and a caging device. The rotor is made in the form of two inertia masses, each of which is formed by a socket-shaped rim. Spiral leaf springs fastened by the external ends with the rims with their relative displacement along the generating line of the rim are positioned in the inner cavities of the rims. The inertia masses are installed in opposition by the open cavities on a common shaft in the bush of the disk-shaped inner gimbal. The ends of the bush are inserted under the springs in the cavities of the inertia masses. One of the inertia masses is connected to the stepped rod latch located in the case, where the pyrotechnical pusher is installed. For the time of acceleration a relative unbalancing of the inertia masses is produced, thus keeping the outer gimbal frame ring from displacement. At the end of acceleration the relative unbalancing of the inertia masses is eliminated, and the outer gimbal frame ring gets released. For cocking the springs their free ends are inserted in the seats on the bushes of the outer gimbal frame ring. The spring cocking terminates in their rewinding from the rim onto the bushes of rim rotation with a subsequent casing. EFFECT: enhanced reliability and accuracy. 3 cl, 5 dwg
