Aero-thermal design of STRATOFLY MR3 hypersonic vehicle

Civil hypersonic flights are one of the key technological challenges of next generation. The EC-funded STRATOFLY (Stratospheric Flying Opportunities for High-Speed Propulsion Concepts) project has the objective of assessing the potential of this type of high-speed transport vehicle to reach TRL6 by 2035, with respect to key technological, societal and economical aspects, namely thermal and structural integrity, low-emissions combined propulsion cycles, subsystems design and integration including smart energy management, environmental aspects impacting climate change, noise emissions and social acceptance, and economic viability accounting for safety and human factors. This paper presents the aerothermal design of the new STRATOFLY MR3 hypersonic vehicle.
