abstract = "The perturbative integral method was applied to quantify the
contribution of external forces during a specific interval of time
in trajectories of spacecraft around asteroids and under the
Luni-solar influence. However, this method has not been used to
quantify the contributions of drag in aerocapture and aerobraking.
For this reason, the planet Mars is selected to apply this method
during an aerogravity-assisted maneuver. Several trajectories are
analyzed, making use of a drag device with area to mass ratios
varying from 0.0 to 20.0 m2/kg, simulating solar sails or de-orbit
devices. The mathematical model is based in the restricted
three-body problem. The use of this maneuver makes it possible to
obtain the variations of energy in the trajectory, replacing
expensive maneuvers based on fuel consumption. To observe the
effects of the maneuvers, different values of pericenter velocity
and altitude were selected for prograde and retrograde orbits. The
innovation of this research is the application of an integral
method to quantify the delta-V of the aero gravity maneuver,
comparing the cost of the maneuver with the traditional methods of
space propulsion. The results allow the identification of orbits
with conditions to capture, and the perturbative maps show the
velocity variations.",
