DESIGN OF AEROGRAVITY-ASSIST TRAJECTORIES

Aero-gravity assist (AGA) trajectories are optimized in the sense of maximizing AV obtained by the fly by, maximizing aphelion, minimizing perihelion, and minimizing the time of flight (TOF) for a particular destination planet. A graphical method based on Tisserand's criterion is introduced to identify potential AGA trajectories. To demonstrate the application of the theory, patched-conic AGA trajectories are computed to each planet in the Solar System. For an L/D of 7, and a launch VQO of 6.0 km/s, Pluto may be reached in 5.5 years using a Venus-Mars-Venus AGA.
