abstract = "The impulsive or powered aero-gravity-assisted is an orbital
maneuver that combines three basic components: A gravity-assisted
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 aerodynamic forces. The
present paper uses this type of maneuver considering atmospheric
drag and lift forces. The lift is applied orthogonal to the
initial orbital plane to generate an inclination change in the
trajectory of the spacecraft, which are very expensive maneuvers.
The lift to drag ratio selected goes up to 9.0, because there are
vehicles, like waveriders, designed to have these values. When the
spacecraft is located at the periapsis the impulse is applied to
increase or decrease the variation of energy given by the
aero-gravity-assisted maneuver. The planets Venus and Mars are
selected to be the secondary bodies for the maneuver, due to their
atmospheric density and strategic location to provide possible use
for future missions in the solar system. Results of the numerical
simulations show the maximum changes in the inclination obtained
by the maneuvers as a function of approach angle and direction of
the impulse, lift to drag ratio and ballistic coefficient. In the
case of Mars, inclination change can be larger than 13°, and for
Venus higher than 21°. The energy and inclination variations are
shown for several selected orbits.",
