titleOfInvention | THREE-AXIS GYROSCOPIC BLOCK |
abstract | 1. A three-axis gyroscopic unit of an onboard inertial navigation system, characterized in that it contains a metal-evacuated metal case in the form of a single-section monolithic rod, in the landing slots of which a gas absorber and three uniaxial solid-state wave gyroscopes (TWGs) are sealed, each of which contains a hemispherical resonator with a central a rod-type holder made of quartz glass and installed inside the resonator with a gap to the inner surface of its hemisphere an electromechanical circuit board made in the form of a spherical segment with a central sample and special electrodes used to excite the resonator and register its vibrations, and with corresponding pressure outputs and current leads for attaching to the electronics block serving the TWG and consisting of three electronics channels mounted on a common triangular base sections parallel to the longitudinal axis of the housing with TWG, while the landing slots formed in the body of the housing are sequentially and orthogonally located and others are communicated with each other by a common evacuated channel, and the electronics unit and the gyroscopic unit interconnected by installation and connecting elements are placed in a protective casing and are fixed in it by shock-absorbing rings made of plastic material, for example polyurethane. ! 2. The triaxial gyroscopic unit according to claim 1, characterized in that the getter therein is provided with a housing, inside of which there is an active substance and a heating element, for example a spiral, while the active substance is made of |
