             abstract = "This paper studies maneuvers for a spacecraft that combines an 
                         impulse with a Swing-By performed with a celestial body that is 
                         traveling in an elliptical orbit around the primary body of the 
                         system. The objective is to measure the variations of the 
                         velocity, energy and angular momentum of the spacecraft due to 
                         this maneuver. An algorithm is developed to obtain the energy and 
                         the angular momentum variation for this particular type of powered 
                         Swing-By. In this way, it is possible to find the best direction 
                         and instant to apply the impulse in order to maximize the energy 
                         variation. The results show that applying the impulse in the 
                         direction of the motion of the spacecraft is generally not the 
                         optimal solution and the results depends on the position of the 
                         secondary body in its orbit around the main body and the 
                         eccentricity of the orbits of the primaries. Compared to the 
                         circular case, several situations where the impulse is retrograde 
                         appears when the secondary body is at the periapsis of its orbit, 
                         due to the larger gains that can be obtained from the new geometry 
                         of the Swing-By.",
