Abstract
The effects of the climate crisis needs to be addressed in order to safeguard our Planet and human life. For this purpose, the H2020 STRATOFLY project aims at developing a hypersonic hydrogen-fueled vehicle that will be able to fly antipodal routes without emitting carbon oxides. The reference vehicle is STRATOFLY MR3, which is powered by six Air-Turbo Rocket (ATR) engines and a single Dual-Mode Ramjet (DMR) engine. The ATR engines are operational from take-off up to Mach 4, after which they are gradually shut down while the DMR is activated to reach Mach 8. The cruise takes place at Mach 8 and at an altitude between 32 and 36 km.
The focus of the thesis consists of developing parametric models able to predict nitrogen oxides (NOx) emissions of the STRATOFLY MR3 vehicle since the conceptual design phase
