Zusammenfassung:This paper focuses on the hypersonic vehicle in consideration of oscillation and aerodynamic heating problems during reentry process, for trajectory optimization, penalty function method and ε level comparison are introduced for transforming the unconstrained waterweeds algorithm into constrained algorithm to solve multi-objective optimization problems, in which a novel and more precise criterion based on time-scales separation guidance for oscillation optimization is put forward indicating waterweeds algorithm to get a better optimal result. The algorithm transformed is successfully applied to trajectory design.
