An adhesive system for use in minimizing the negative environmental influences on a fiber optic gyroscope comprises a free-standing substantially cylindrical sensing coil (12) having an inner coil surface, a rigid substantially cylindrical coil-supporting structure or hub (10) having a cylindrical wall and an outer surface, a plurality of grooves (16) formed into the hub's outer surface, a plurality of slots (24) formed into the outer surface of hub (10) and an adhesive (14) affixing hub (10) to coil (12). Adhesive (14) may be injected into manifolds (18) located in the cylindrical wall of hub (10), travel through the slots (24) into a gap existing between coil (12) and hub (10). Excess adhesive (14) may flow into grooves (16). Different orientations and sizes of grooves (16) and slots (24), different types and amounts of adhesive (14), and different thicknesses of adhesive between the coil (12) and hub (10) may be used to achieve suitable adhesion. The adhesive system may further include a stress buffer (22) and an additional adhesive (20) to further minimize environmental influences on coil (12). Specifically, a first adhesive (14) affixes the inner surface of buffer (22) to the outer surface of hub (10). A second adhesive (20) affixes the outer surface of buffer (22) to the inner surface of coil (12). |
