ABSTRACT:
A low cost, simple to manufacture, two axis gyro having an outer flexure assembly and an inner flexure assembly. Each flexure assembly contains two flexure hinges which represent a reduction in the number of hinges and milled cuts from those required in prior art devices. The inner flexure assembly is designed to nest within the outer flexure assembly and both are mounted centrally on a rotatable shaft for rotation about the gyro spin axis. The two flexures of the outer assemblies are separated 180.degree. from each other and adjacent to two slots also separated by 180.degree. in the rim of the outer gimbal. Likewise, the two flexures of the inner flexure assembly are separated 180.degree. from each other and 90.degree. from each of the outer flexures. The outer flexure assembly axis is offset axially by a controlled amount from the inner flexure assembly axis to achieve nominal balance on both flexure axes.
