ABSTRACT:
A fluid floated inertial platform is inertially stabilized by means of a plurality of hydraulic torquers which operate in response to electrical stabilization signals which may be generated in response to gyro pickoffs on stabilizing gyros for each of the three stabilization axes. Each of these hydraulic torquer devices comprises a deflector member, which may be in the form of a section of a cylinder, this deflector member being supported on a base member mounted in the surface of the platform. The deflector is supported on the base member by means of flexible strips or tapes which permit rotatable motion of the deflector in response to torquing signals. Such rotatable torquing of the deflector is provided by means of an armature mounted on the deflector which operates in conjunction with an electrical torquer on the base member which receives electrical torquing signals from the stabilization system. One or more fluid jets are fed from one or more nozzles at the surface of the platform against the body of the deflector. With the deflector in its "neutral" position, each jet is split into a pair of equal force jets which impinge against the casing in which the platform is supported, equally but oppositely, such as to effectively cancel each other out. When a deflector is rotated one way or the other from neutral in response to an electrical torquing signal, the magnitudes of the paired jets become unequal in accordance with the magnitude and direction of this rotation, thereby providing a torque on the platform in response to the electrical torquing signal.
