- As eluded in previous studies, with special reference to those carried out in the European framework, some innovative high-speed aircraft configurations have now the potential to assure an economically viable high-speed aircraft fleet. They make use of unexploited flight routes in the stratosphere, offering a solution to the presently congested flight paths while ensuring a minimum environmental impact in terms of emitted noise and green-house gases, particularly during stratospheric cruise. However, only a dedicated multi-disciplinary integrated design approach could realize this, by considering airframe architectures embedding the propulsion systems as well as meticulously integrating crucial subsystems. In this context, starting from an in-depth investigation of the current status of the activities, the STRATOFLY project has been funded by the European Commission, under the framework of Horizon 2020 plan, with the aim of assessing the potential of this type of high-speed transport vehicle to reach Technology Readiness Level (TRL) 6 by 2035, with respect to key technological, societal and economical aspects. This paper aims at summarizing the main results achieved so far to solve the main issues related to 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.

Conference paper (peer-reviewed)abstract
- This paper addresses the main progresses and achievements of the H2020 STRATOFLY Project, funded by the European Commission, under the Horizon 2020 framework, specifically looking at the latest results in terms of environmental sustainability. In particular, starting from reporting the main environmental challenges posed by high-speed civil transportation, at local, regional and global levels, this paper describes the way in which the STRATOFLY MR3 vehicle, a Mach 8 waverider fueled with liquid hydrogen, promises to limit the overall environmental impact. In details, firstly, the paper describes some of the main technological improvements adopted to reduce the aircraft emission and then it reports about the status of the numerical and experimental test campaigns on the high-speed engine, showing the results achieved so far. This preliminary emission inventory allows for the evaluation of emission indexes throughout the mission profile, the verification of the compliance with the ICAO prescriptions, the estimation of the impact on air quality and climate and eventually, when necessary, the paper proposes adequate mitigation actions.
