GEAR MEASURING LINEAR AND ANGULAR VELOCITIES AND ANGLE OF TURN OF MOVING OBJECT Russian patent published in 1997 - IPC

FIELD: gyroscopic instrumentation, platform-free inertial navigation systems. SUBSTANCE: proposed gear has three meters of linear velocity and angle of turn which sensitivity axes are orthogonal to each other, differentiator, former of modulus, voltage-to-code converter, unit generating correction signals and amplification-conversion unit connected in series, unit determining sign of linear acceleration and angle velocity which input is connected to second output of differentiator and which output is linked to second input of voltage-to-code converter. Each meter incorporates first integrating gyro of linear acceleration, sensor of position of meter and second integrating gyro of linear acceleration placed in series along axis of sensitivity of meter, information processing unit which first and second outputs are connected to corresponding input of voltage-to-code converter and differentiator. Sensor of position of meter is manufacture in the form of two stators with windings and rotor. One of stators is anchored in case of meter, the other stator is set on axis of sensitivity of first integrating gyro. Rotor is positioned on axis of sensitivity of second integrating gyro. Outputs of stator windings are connected to proper inputs of information processing unit. Sensor of moment of each meter is located on suspension axis of one of integrating gyros. Inputs of sensors of moment are connected to proper output of amplification-conversion unit. Each integrating gyro has free unbalanced gyroscope incorporating sensitive element and system of interframe correction. Sensitive element of each integrating gyro has two gyromotors interconnected by means of adapter and having identical structural parameters. Vectors of kinematic moments of gyroscopes are directed in opposition. EFFECT: expanded application field, increased functional precision and reliability. 4 dwg
