Abstract
A monolithic two axis gimbal suspension system for a tuned inertial instrument includes flexure hinges which are formed monolithically integral therein to define the pivot axis of the suspension system, each monolithically integral flexure hinge having aligned pairs of skew, crossed bridges integral with the relatively rotatable gimbals of the suspension system. The suspension system is used in a dry tuned gyroscope to suspend the gyro rotor from the gyro spin shaft. A method for making the monolithic suspension system comprises electro discharge machining of a monolithic workpiece mounted on a movable mandrel. Monolithically integral flexure hinges comprising skew, crossed bridges formed therein, interconnect gimbal portions which are formed in the workpiece. Construction of an improved tuned gyroscope employing the monolithic suspension system in a single compartment housing is described.
