GYROSCOPIC INSTRUMENT AND PROCESS OF ADJUSTMENT OF ITS DRIFT Russian patent published in 1998 - IPC

FIELD: measurement technologies. SUBSTANCE: gyroscopic instrument is designed for usage as transmitter of bearing angle on antitank guided rockets rotating along roll. Rotor is manufactured in the form of disc with balancing screws arranged on its periphery. Cylindrical bushing uniaxial to rotor is displaced with regard to center of mass. Rotor bearing and internal gimbal suspension are positioned in space of bushing. Center of mass of disc is displaced from center of gimbal suspension. Aerodynamic disc in the form of truncated cone is installed in body and is anchored uniaxially to rotor. Booster is joined to rotor with the use of releasable connection. Booster ensures rotation of rotor in direction opposite to rotation of body with gimbal suspension. Adjustment nut is fixed on rotor bushing. While testing and adjusting drift body with gimbal suspension is rotated in opposition to rotor. Drifts n horizontal and vertical planes are checked simultaneously. Drift in horizontal plane is compensated by displacement of center of mass of gyroscope by means of movement of adjustment nut in rotor bushing from center of gimbal suspension. Drift in vertical plane is compensated by displacement of aerodynamic disc with reference to rotor. EFFECT: enhanced precision of instrument thanks to reduction of its drift. 4 cl, 4 dwg
