MODULE OF SPACECRAFT ENGINE PLANT (VERSIONS) Russian patent published in 2006 - IPC B64G1/26 B64G1/40 

FIELD: spacecraft engine plants, mainly geostationary communication satellites; orientation of satellite and correction of its orbit.

SUBSTANCE: proposed module of spacecraft engine plant includes low-thrust engine (or engine package) mounted in biaxial suspension on rod and components of engine plant pneumatic system. Engine is mounted on one end of rod and pneumatic system components are mounted on other end of rod. Articulation securing the rod to spacecraft case is located between engine (or engine package) and pneumatic system components. Biaxial suspension makes it possible to perform independent rotation of engine (or engine package) relative to rod at two perpendicular axes through 90° around each axis. Rod securing articulation makes it possible to rotate the rod through 360° relative to spacecraft case. Provision is made for shaping correcting pulse during operation of low-thrust engine (or engine package) in any direction for maintenance of point of sight of spacecraft on orbit and creating required control moment around center of mass of spacecraft for its orientation.

EFFECT: enhanced efficiency.
