ABSTRACT:
A gimballed platform stabilization system includes at least one outer member, an inner member, and an intermediate inertia bearing member. The intermediate member has limited coaxial angular freedom about an isolation axis with respect to the inner and outer members. A limited freedom (about the isolation axis) torsional flexure element is coupled between the intermediate and inner members. A first servo loop establishes a "negative spring rate" in parallel with the positive spring rate associated with the flexure element, maintaining a low net effective spring force on the inner member. A second servo loop prevents the angular excursion between the intermediate member and the inner member to extend beyond the limits of the flexure element. This inertia reaction stabilization configuration reduces disturbing torques from a stabilization axis to non-linear spring residuals which are relatively small.
