A name given to various forms of gyroscope.
1879Thomson & Tait Nat. Phil. I. i. §345 The ordinary gyrostat (a rapidly rotating fly-wheel pivoted as finely as possible within a rigid case, having a convex curvilinear polygonal border, in the plane perpendicular to the axis through the centre of gravity of the whole). 1902Encycl. Brit. XXXII. 578/1 For the purpose of controlling the horizontal direction this boat [sc. a submarine] is fitted, in addition to a vertical rudder, with a ‘gyrostat’, the motion of which instrument is maintained by an electric motor. Previous to making a start the boat must be headed in the direction in which it is intended to move; when the gyrostat, once started, will..continue to rotate about an axis invariable in direction, and any departure from this will be detected, whether the boat be above the surface or below it. 1922Ibid. XXX. 44/1 Gyrostats are also used in aircraft as azimuth indicators for experimental or test purposes; they may some day be used as part of a gyrostatic compass. |
