Correction to: Conceptual Design Optimization of Liquid-Hydrogen-Fueled Transport Aircraft for Environmental and Economic Performance (25th AIAA International Space Planes and Hypersonic Systems and Technologies Conference, 2023)

Correction Notice 1.) In the abstract, the 4th to last and 5th to last sentence read “The analysis shows that LH2-powered aircraft can reduce the environmental impact of Jet-A aircraft by 88%. As a result of higher assumed fuel costs, the operating costs are higher(+28% for the regional and +53% for single-aisle) for the LH2-powered aircraft.” These sentences are corrected below: The analysis shows that LH2-powered aircraft can reduce the environmental impact of Jet-A aircraft by 88% for a regional turboprop and 87% for a single-aisle aircraft. As a result of higher assumed fuel costs, the operating costs are higher (+30% for the regional and +61% for single-aisle) for the LH2-powered aircraft. 2.) On page 9, the third sentence of the second paragraph in Section III.A says “There is less than 0.08% variation in the optimization cost of the two extreme ends of the pareto fronties.” This sentences is corrected below: There is less than 0.036% variation in the optimization cost of the two extreme ends of the pareto frontiers.
