| dc.description.abstract | Discrete-event drag modulation systems are an attractive option for flight control during aerocapture. These systems require precise timing of the drag modulation events to ensure accurate final orbit delivery. Two different guidance schemes for discrete-event drag-modulated aerocapture are evaluated: a heuristic deceleration profile curve-fit method and a higher-fidelity numeric predictor-corrector algorithm. The accuracy and computational performance of these algorithms is examined in a series of Monte-Carlo simulations of aerocapture missions at Earth, Mars, and Titan. Results indicate that while the deceleration curve-fit method requires minimal amounts of computation time, additional modifications must be made to ensure its robustness to day-of-flight uncertainties. At both low and medium guidance rates, the numeric predictor-corrector algorithm is able to effectively guide drag modulation events in the face of uncertainty. | |
