A study to assess the feasibility of a supersonic transport aircraft (SST), which is hydrogen-powered, was undertaken. For this purpose, the aircraft design environment Aircraft Design Box (ADEBO) of TU Munich was modified for kerosene and hydrogen SST design. The modifications for the kerosene SST design were validated with the design of a reference aircraft, using the same requirements as the Concorde, which resulted in a close match. Using this reference, a baseline liquid hydrogen-powered SST with as little configurative changes as possible was designed, which led to significant changes on overall aircraft level. Among the changes were a small increase in maximum take-off mass, alongside large increases in operating empty mass, energy consumption in the design mission, and zero-lift drag. The placement of hydrogen tanks inside the fuselage also led to an increase of the fuselage length to over 80 m, which violates airport constraints. To remedy these implications, in a parametric study, a modernized engine was used in the design of the liquid hydrogen-powered SST. Although this engine change significantly reduces the design masses, energy consumption, and fuselage length, its aerodynamic efficiency in cruise decreases in comparison to the baseline hydrogen SST. However, this design shows potential for the improvement of aerodynamic characteristics via configurative changes, such as a new wing planform and fuselage shaping. To fully understand the potential of the aircraft presented in this study, in the future, the evaluation of their sonic boom characteristics and climate impact should be undertaken.
