abstract = "It is estimated that more than 22.000 objects are in orbit around
the Earth, with a total mass of 8.400.000 kg. These numbers
consider only objects with dimensions above 10 cm and some
non-operational, but still orbiting satellites without control
(debris). The debris represent a hazard to operational satellites
and aerospace operations due to the high probability of
collisions. Due to the interaction of the debris with the
atmosphere of the Earth and the solar activity, they began to lose
energy and finally decay. During the de-orbit process, the debris
fall into the Earths atmosphere at hypersonic speeds and these
objects can break-up and/or be fragmented due to the aerodynamics,
thermal and structural loads. It is important to obtain the
trajectory and attitude of any fragment to determine the possible
survival mass, impact area, hazard conditions and risks to the
population, the air traffic control, and infrastructure. In this
case, it is implemented a computational code to integrate the
equations of motion to propagate the dynamics and kinematics of
spherical debris or propellant tanks. It is also analyzed the
results of trajectories with six degrees of freedom, atmospheric
winds, and Magnus effect. A voxel method is implemented to analyze
the tanks heat transfer, surface temperature and structures
stress. To determine and observe the influence of the rotation and
the Magnus force in six reentry spherical bodies, three materials
are selected; aluminum alloy, due to its application in many
aerospace structures; titanium and graphite epoxy I, due to their
highest melting point and specific heat. Generally, these
materials are used in tanks and rocket motors. More than 62
trajectories were simulated. The mathematical model and
computational code were validated in three degrees of freedom.
Results are compared with data from other computational tools
available in the scientific literature. The results show a good
approximation with reported cases of study. New results are
generated in the simulations of rotational bodies, due to the
influence of aerodynamic forces in the trajectory and the changes
in the stagnation regions. Due to the implementation of wind and
rotation of the debris, the fragments increased the survivability
and the dispersion area.",
