内容記述 | A multi-objective optimization and a robust optimization are developed as a realistic comprehensive optimization method of the TSTO spaceplane. The result of the multi-objective optimization reveals the strong trade-off relation between the gross take-off weight and the Orbiter separation time minimizations. The propulsion parameter that controls the flow rate of captured air during the supersonic flight turns out to play an important role in this trade-off relation. The result of the robust optimization, in consideration of both the objective function optimality and robustness of the gross take-off weight, shows that the use of larger thrust engine with less fuel leads to the improvement of the optimality. On the other hand, the most robustest design did not coincide with the lightest gross take-off weight design. This result indicates that balancing the amount of fuel with the engine thrust is necessary for the improvement of the robustness. | |||||
