Resumo

In a swing-by maneuver, the variation of energy of the spacecraft is controlled by the angle, velocity, and distance of approach. These parameters are defined by the incoming trajectory, when the spacecraft is far from the planetary atmosphere. The passage of the spacecraft by the atmosphere generates aerodynamic forces, affecting its trajectory and giving new forms of control, which are functions of the attitude of the spacecraft. This maneuver is called aerogravity-assist maneuver. This control can change the direction and magnitude of aerodynamic forces. Previous results showed the influence of the lift-to-drag ratio and the effects of the application of impulses in this maneuver. However, the variations of energy due to the control that can be given by the bank angle have not been studied before, and this study constitutes the main new aspect of the present paper. In this research, it is implemented the classical methodology to calculate the variations of energy to analyze the effects of the bank angle in aerogravity-assist maneuvers. This analysis can identify regions of collisions and the variations of energy as a function of the bank angle, giving new alternatives to this maneuver that are not available in the literature. (AU)
