METHOD FOR UNLOADING INERTIAL ACTUATORS OF SPACECRAFT AND DEVICE FOR IMPLEMENTING METHOD Russian patent published in 2025 - IPC B64G1/28 G05D1/49 

FIELD: cosmonautics.

SUBSTANCE: group of inventions relates to space engineering and can be used for three-axis non-consumption, independent of external physical fields unloading of inertial actuators. Unloading is performed by dumping of kinetic moment on engine-flywheel installed in gimbal suspension. Before the kinetic moment is reset, the spacecraft is turned to the position, at which vector of kinetic moment of inertial actuators along unloaded orientation axis and vector of kinetic moment of engine-flywheel are collinear. Unloading device comprises a control module and a flywheel engine connected to it in a gimbal suspension, the external frame of which is installed in the housing of the spacecraft so that its axis of rotation is not parallel to any of the orientation axes of the spacecraft. Proposed device comprises engine-flywheel speed and direction transducer, angular displacement transducers and electrically controlled caging mechanisms of gimbal suspension inner and outer frames.

EFFECT: possibility of non-consumption unloading in any orbits and in distant space, reduced duration of unloading and forced interruptions in operation.
