This paper deals with the preliminary design and sizing of the Thermal and Energy Management Subsystem elaborated by ESA for the LAPCAT MR2 high-speed vehicle. The working principle of this subsystem is based on the exploitation of liquid hydrogen boil-off. The friction heat loads penetrating the aeroshell, all along the point-to-point hypersonic mission, generates boil-off within the cryogenic tanks that can be exploited for cooling and power generation purposes. This work aims at analyzing the various components which the TEMS consists of, suggesting proper Estimation Relationships (ERs) for mass, volume and power budgets. Eventually, a short discussion about examples of sensitivity analysis aimed at deriving the impact of operating parameters on subsystem budgets is proposed as introduction to future works of the research.
