             abstract = "The present paper studies the effects of a powered Swing-By 
                         maneuver, considering the particular and important situations 
                         where there are energy gains for the spacecraft. The objective is 
                         to map the energy variations obtained from this maneuver as a 
                         function of the three parameters that identify the pure gravity 
                         Swing-By with a fixed mass ratio (angle of approach, periapsis 
                         distance and velocity at periapsis) and the three parameters that 
                         define the impulsive maneuver (direction, magnitude and the point 
                         where the impulse is applied). The mathematical model used here is 
                         the version of the restricted three-body problem that includes the 
                         Lema{\^{\i}}tre regularization, to increase the accuracy of the 
                         numerical integrations. It is developed and implemented by an 
                         algorithm that obtains the energy variation of the spacecraft with 
                         respect to the largest primary of the system in a maneuver where 
                         the impulse is applied inside the sphere of influence of the 
                         secondary body, during the passage of the spacecraft. The point of 
                         application of the impulse is a free parameter, as well as the 
                         direction of the impulse. The results make a complete map of the 
                         possibilities, including the maximum gains of energy, but also 
                         showing alternatives that can be used considering particularities 
                         of the mission.",
