abstract = "Analytical equations describing the velocity and energy variation
of a spacecraft in a Powered Swing-By maneuver in an elliptic
system are presented. The spacecraft motion is limited to the
orbital plane of the primaries. In addition to gravity, the
spacecraft suffers the effect of an impulsive maneuver applied
when it passes by the periapsis of its orbit around the secondary
body of the system. This impulsive maneuver is defined by its
magnitude \δV and the angle that defines the direction of
the impulse with respect to the velocity of the spacecraft
(\α). The maneuver occurs in a system of main bodies that
are in elliptical orbits, where the velocity of the secondary body
varies according to its position in the orbit following the rules
of an elliptical orbit. The equations are dependent on this
velocity. The study is done using the patched-conics
approximation, which is a method of simplifying the calculations
of the trajectory of a spacecraft traveling around more than one
celestial body. Solutions for the velocity and energy variations
as a function of the parameters that define the maneuver are
presented. An analysis of the efficiency of the powered Swing-By
maneuver is also made, comparing it with the pure gravity Swingby
maneuver with the addition of an impulse applied outside the
sphere of influence of the secondary body. After a general study,
the techniques developed here are applied to the systems
Sun-Mercury and Sun-Mars, which are real and important systems
with large eccentricity. This problem is highly nonlinear and the
dynamics very complex, but very reach in applications.",
