abstract = "The objective of the present paper is to derive a set of
analytical equations that describe a swing-by maneuver realized in
a system of primaries that are in elliptical orbits. The goal is
to calculate the variations of energy, velocity and angular
momentum as a function of the usual basic parameters that describe
the swing-by maneuver, as done before for the case of circular
orbits. In elliptical orbits the velocity of the secondary body is
no longer constant, as in the circular case, but it varies with
the position of the secondary body in its orbit. As a consequence,
the variations of energy, velocity and angular momentum become
functions of the magnitude and the angle between the velocity
vector of the secondary body and the line connecting the
primaries. The patched-conics approach is used to obtain these
equations. The configurations that result in maximum gains and
losses of energy for the spacecraft are shown next, and a
comparison between the results obtained using the analytical
equations and numerical simulations are made to validate the
method developed here.",
