<p>The bi-liquid propulsive system for an artifical satellite is characterized in that the ergols are unequally distributed in at least two pairs of tanks (12, 16) and (14, 18) associated in such a way as to have at disposal additional fuel in a first pair of tanks and additional comburent in the second pair of tanks, and in that the different pairs are susceptible of being successively used during a predetermined period of time so that the exhaustion of a first ergol in one tank (14 or 16) indicates that the normal residual life time of the satellite is at the most approximately equal to said predetermined period of time and that after exhaustion of the second ergol of the tank (16 or 14) the two tanks (12 and 18) containing each an ergol in excess are associated in order to extract the satellite.</p> |
