abstract = "The present paper studies the powered Swing-By maneuver when
performed in an elliptical system of primaries. It means that
there is a spacecraft travelling in a system governed by the
gravity fields of two bodies that are in elliptical orbits around
their center of mass. The paper particularly analyzes the effects
of the parameters relative to the Swing-By (Vinf-,rp,\ψ),
the orbit of the secondary body around the primary one
(e,\ν) and the elements that specify the impulse applied
(\δV,\α) to the spacecraft. The impulse is applied
when the spacecraft passes by the periapsis of its orbit around
the body, where it performs the Swing-By, with different
magnitudes and directions. The inclusion of the orbital
eccentricity of the primaries in this problem makes it closer to
reality, considering that there are many known systems with
eccentricities different from zero. In particular, there are
several moons in the Solar System which orbits are not circular,
as well as some smaller bodies, like the dwarf planet Haumea and
its moons, which have eccentricities of 0.25 or even larger. The
behavior of the energy variation of the spacecraft is shown in
details, as well as the cases where captures and collisions occur.
The results show the conditions that optimize this maneuver,
according to some given parameters, and how much can be obtained
in terms of gains or losses of energy using the best conditions
found by the algorithm developed here.",
