摘要：
With the goal of achieving net zero carbon emissions from commercial aircraft，new forms of energy that can be put into large-scale applications in the future are found . Comparative evaluations are carried out with the aspects of specific energy，specific power，emissions reduction and economic effect. Combined with the mass comparison of the energy power system of various levels of civil aircraft products such as commuter，narrow-body，wide-body，the hydrogen energy with gas turbine is shown to be the most feasible energy power combination in the medium and long term of the future. The overall design process for hydrogen-powered aircraft is established. Conceptual design of medium-range hydrogen-powered passenger aircraft is carried out，and the aerodynamic efficiency is estimated by means of drag decomposition，and empty mass is estimated with the method of classified mass calculation. The overall parameters and preliminary conceptual scheme of a feasible hydrogen-powered aircraft are formed with design iteration. The results show that the use of power structure of liquid hydrogen with gas turbine can increase the take-off mass by within 10% compared with the conventional kerosene-powered aircraft for short to medium range，narrow-body civil aircraft. With the consideration of the foreseeable breakthroughs in hydrogen power system and hydrogen storage technology in the next 10 to 20 years，hydrogen-powered aircraft is the most potential solution to achieve net-zero carbon emissions for air transport. © 2024 Journal of Propulsion Technology.
