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