• and
• a second tank defined between the first substantially cylindrical enclosure and a second substantially cylindrical enclosure present around said first substantially cylindrical enclosure and extending along the longitudinal axis of the thruster body, the second tank being closed at a first end and open at a second end, the second tank containing a second solid propellant charge having at least one combustion face exposed at the second end of said second tank, the second tank being in communication with the second valve set.
