The thrusters (14, 16, 18 or 20) are fired to produce a small impulse int he direction of the desired Velocity change to begin motion of the propellant within the fuel tank in the opposite direction. After the fuel has moved within the tank to a location in which the propellant centre of mass is aligned with the propellant tank (22) centre of curvature in the direction of the desired velocity change, thrusters (14, 16, 18 or 20) are again fired. This produces a force in the direction of the current velocity of the propellant centre of mass to stop the propellant centre of mass relative to the propellant tank (22). With the centre mass of the propellant now aligned with the propellant tank centre of curvature in the direction of the desired velocity change, the thrusters (14, 16, 18, or 20) are again fired to produce the desired velocity change. |
