Abstract

The present paper presents the design of a long range aircraft concept featuring liquid hydrogen (LH2 ) as main energy source. This concept has been created during a Bauhaus Luftfahrt e.V. internal design project and is named Hyliner (2.0). At first, the definition of the top level aircraft requirements are described, including the motivation for the reduction of the cruise Mach number to 0.7 and the increase of cabin space available per passenger. Afterwards, the derivation of the Hyliner (2.0) from a conventional long range aircraft with the same technology level representative for an entry into service date of 2040 is established. Design decisions of the Hyliner (2.0) are explained and its performance and qualitative impact on emission is discussed. While the energy consumption of the Hyliner (2.0) is 9% higher compared to the conventional reference aircraft with the same technologies integrated, the combustion of hydrogen rather than kerosene offers a possible reduction of the climate impact on long range operations.
