HYDRODYNAMIC GYROSCOPE Russian patent published in 2004 - IPC

FIELD: military equipment. SUBSTANCE: invention is related to measurement elements of systems of control and stabilization of rocket missiles, for example, rocket missiles of salvo fire systems. In agreement with invention hydrodynamic gyroscope has body, rotor with adjustable cavity filled with fluid partially. Rotor comprises left and right cups interjoined via adjustable member. Internal surface of cups is spherical, centers of spheres are displaced from center of cavity in rotor. Spherical float with constant ring magnet is positioned in cavity of rotor. Gyroscope includes cylindrical magnetic circuit, signal coil and electric motor. It is supplemented with adjustable correction unit coming in the form of two cylindrical rings produced from magnetically soft material, which are installed on edges of internal surface of cylindrical magnetic circuit coaxially to rotor for axial movement. Constant ring magnet is manufactured in compliance with relations where A, H, D_m are correspondingly height, thickness and outer diameter of constant ring magnet; D_f is diameter of float. EFFECT: raised precision characteristics of gyroscope thanks to rise of gain factor and time constant. 3 dwg
