This paper aims at presenting a tool developed by ONERA in order to support the designer during the
initial conceptual design phase of high-speed civil transportation aircrafts. The tool helps to evaluate
the long-term sustainability of operative concepts by providing a first optimized 0D sizing (maximum
take-off mass, fuel mass, dry mass, volume, wetted surface, …) of a high speed civil aircraft as a
function of range (3000 to 18000 km), number of passengers (10 to 300), type of fuel (kerosene,
LCH4, LH2), cruise Mach number (4 to 8), ascent and descent accelerations (+/- 0.15g) and then by
providing the associated ticket price per passenger. This paper, after introducing the sizing tool and
the physical and implemented cost models, provides and discusses the results obtained for different
missions. Particularly, links between the ticket price and the inputs mission specifications, geometric
features, type of fuel are established.
