Aerospace Instrument-Making Annotation << Back Indicator-powered gyrostabilizer with nonrigid drive Kuleshov A.V. Fateev V.V. We offered one of the construction principles of the smallsize gyroscopic stabilizers with nonrigid drive, which consists in install of additional gyro with two degrees of freedom on the platform of indicator gyrostabilizer. This gyro is intended to reduce the influence of nonrigidity in the stabilization drive on stability and accuracy of the gyrostabilizer. In this gyrostabilizer the additional gyro with two degree of freedom perform only power role. This gyro is an additional support body, from the side of which an additional stabilizing gyroscopic moment is applied to the platform with the stabilization object. This reduces the quality requirements for the feedback loop of the indicator stabilization system, and hence reduces the influence of nonrigidity in the drive chain on stability and gyrostabilizer accuracy. The scheme of proposed gyrostabilizer with one stabilization axis and the questions of it’s accuracy and stability are considered in the article. Key words indicator gyrostabilizer, small size gyrostabilizer, powered gyrostabilizer, indicator-powered gyrostabilizer, nonrigid drive, the cutoff frequency.
