Abstract:
|
Escaping from the solar system by receiving
gravity assist from the Earth is considered
in this paper. A simple procedure,which
neglects the eccentricity of the Earth’s orbit and uses the two-body problem equations
and the patched-conic approximation, provides
near-optimal trajectories using either a
single or multiple Earth flybys. The analysis
shows that the amount of propellant required
to escape from the solar system decreases
with the number of flybys, but the mission
time increases. The same approach is also
used to find near-optimal trajectories that
use a single powered flyby. The eccentricity
of the Earth’s orbit can be exploited to
reduce the characteristic velocity; an
indirect optimization procedure provides
the most favorable locations where the Earth
should be intercepted. |
