Abstract: “Gyroscope devices are primary units for navigation and control systems that have wide application in aviation, in space, on ships and other industries. The main property of the gyroscope device is maintaining the axis of a spinning rotor. This gyroscope peculiarity is represented in terms of gyroscope effects in which mathematical models have been formulated on the law of kinetic energy conservation and a change in an angular momentum. The known gyroscope theories are represented by numerous publications, which analytical approaches cannot give true results. The nature of gyroscope effects is more complex than represented in known publications. Recent investigations in this area have demonstrated that the external torque acting on a gyroscope generates several inertial torques which are interdependent and simultaneous action. The gyroscope internal torques are generated by the action of several inertial forces as well as a change in an angular momentum. Latter one does not play first r”
