abstract = "Thse powered aero-gravity-assist is an orbital maneuver that
combines three basic components: a gravity-assist with a passage
by the atmosphere of the planet during the close approach and the
application of an impulse during this passage. The mathematical
model used to simulate the trajectories is the Restricted
Three-Body Problem including the terms coming from the aerodynamic
forces. The present paper uses this type of maneuver considering
that the trajectory of the spacecraft is in the ecliptic plane and
the presence of the atmospheric Drag and Lift forces. The maneuver
in the ecliptic plane can be done due to technologies that
provides spacecraft with high values for the Lift to Drag ratio.
The main advantage is that this maneuver allows the modification
of the semi-major axis of the orbit of the spacecraft using the
gravity of the planet and, at the same time, to change the
inclination, using the high Lift that is perpendicular to the
ecliptic plane. So, it is a combined maneuver that changes two
important orbital parameters at the same time. The Lift is applied
orthogonal to the initial orbital plane to generate an inclination
change in the trajectory of the spacecraft, which is a very
expensive maneuvers when made using propulsion systems. The Lift
to Drag ratio used in the present paper goes up to 9.0, because
there are vehicles, like waveriders, designed to have these
values. When the spacecraft is passing by the periapsis of its
orbit, an instantaneous impulse is applied to increase or decrease
the variation of energy given by the aero-gravity-assist maneuver.
The planets Venus and Mars are selected to be the bodies for the
maneuver, due to their atmospheric density and strategic location
in the Solar System to provide possible uses for future missions.
Results coming from numerical simulations show the maximum changes
in the inclination obtained by the maneuvers, as a function of the
approach angle and direction of the impulse; the Lift to Drag
ratio and the ballistic coefficient. In the case of Mars,
inclination changes can be larger than 13°, and for Venus larger
than 21°. The energy and inclination variations are shown for
several selected orbits. The powered aero-gravity-assist maneuver
generates inclination changes that are higher than the ones
obtained from the powered maneuver and/or the aero-gravity
maneuver.",
