| 摘要 |
The present invention relates to an electric propulsion device for a satellite (100) equipped with at least four active propellers exerting parallel thrust during a transfer, the device comprising means for detecting a propeller breakdown and means for reorienting the propellers, and being characterized in that it comprises means for calculating a reorientation angle of the propellers remaining active during a breakdown of a propeller, the value of the angle being calculated to reorient at least two of the remaining propellers in order to cancel out the total torque around the mass centre of the satellite. |
