Resonator for hemispherical resonant gyroscope, has shell with internal and external surfaces that are offset with respect to each other on revolution axis so that thickness of shell along annular edge is greater than that near pole

摘要

The resonator has a shell (1) with a pole (2) fixed to a support stem (3). The shell has an annular edge (4) delimited by internal and external surfaces (5, 6) that are homothetic and extend around same axis of revolution. The surfaces are offset with respect to each other on the axis so that thickness of the shell along the annular edge is greater than that near the pole. The surfaces are in the form of spherical cap.
