초록

An electric propulsion device for a satellite equipped with at least four active thrusters exerting a parallel thrust upon a transfer, the device comprises means for detecting a thruster failure and means for reorienting the thrusters, and comprises means for computing a reorientation angle of the thrusters remaining active upon a failure of a thruster, the value of the angle being computed to reorient at least two of the remaining thrusters in order to cancel the total torque about the center of mass of the satellite.

1. A propulsion device for a satellite equipped with at least four active thrusters used in parallel, exerting a parallel thrust upon a transfer, the device comprising means for detecting a thruster failure and means for reorienting the thrusters, the device further comprising means for computing a reorientation angle of the thrusters remaining active upon a failure of a thruster, said reorientation angle being computed to reorient at least two of the remaining active thrusters according to a same computed reorientation angle in order to cancel the total...
