Zusammenfassung:
In this work, a short/medium-haul aircraft for 150 passengers is presented. It is powered exclusively by hydrogen to minimize the environmental impact while optimizing the aircraft's performance at the same time. The concept, named HyZero, was developed as part of the NASA/DLR Design Challenge 2021. The basis for the development of HyZero is the identification of specific aircraft requirements and a methodical comparison of different configurations. The design is not only driven by typical key parameters, such as aerodynamics or weight, but also by the best possible integration of a cryogenic liquid hydrogen tank. The aircraft's concept includes the structural design, mission analysis, and a description of the required airport and hydrogen infrastructure. HyZero is compared with a reference aircraft, which is powered with a blend of 30% Sustainable Aviation Fuel. To assess HyZero´s climate impact, CO2-equivalent emissions and fuel consumption are calculated and an optimum between fuel consumption and climate impact is determined. The direct operation costs (DOC) of HyZero are determined using the CeRAS method for an average flight mission. Finally, the costs and the environmental impact considering the emission of greenhouse gases are compared between HyZero and the reference aircraft. The most important design features include a hybrid drive train, a lifting body, and high aspect ratio strut-braced wings. The result is that while HyZero reduces the CO2-equivalent emissions by a factor of 33 the DOC are 95% higher than those of the reference aircraft. This shows that further work is required to make such an aircraft not just environmentally, but also economically feasible.
