DEVICE FOR REDUCTION OF EFFECT OF OSCILLATIONS OF SOLAR-BATTERY PANELS ON ANGULAR MOTION OF ARTIFICIAL EARTH SATELLITE

摘要

FIELD: space engineering. SUBSTANCE: device has two-coordinate drive for orientation of solar-battery panels relative to casing of artificial earth satellite and circular frame to which housing of one of drives is rigidly secured. Housings of drives of proposed device are rigidly interconnected excluding degrees of freedom of these housings relative to each other. Rotor of drive whose output shaft is rigidly connected with flexible member of structure is not kinematically linked with this output shaft. Frame is secured to casing of artificial earth satellite by means of two spherical joints and has one degree of freedom relative to casing of artificial earth satellite. Due to rigid connection of frame with drive, "frame - drive" system has degree of freedom of rotation relative to casing of artificial earth satellite. Device operates as follows: during rotation of rotor and action of moment on side of flexible member of structure, precession effect of frame articulated on casing of artificial earth satellite arises. Articulated joint transmits moment from side of flexible member of structure to casing of artificial earth satellite. EFFECT: reduction of effect of oscillations of flexible member on angular motion of casing of artificial earth satellite about its center of mass.
