In recent years, the global commitment aimed at reducing the environmental impact of all human activities, is increasingly growing: it is therefore in this perspective of farsightedness that aeronautical activity must evolve, setting as an objective of equal importance the satisfaction of users and also a limitation of the direct and indirect emission of pollutants. While on the one hand technological innovation has led to the development of innovations in propulsive terms, thus allowing to travel at hypersonic speeds in accessible commercial flights, on the other hand it has made it necessary to create new techniques for analyzing and forecasting pollutant and greenhouse gas emissions right from the conceptual design phase. In this context, engines such as the ATR, an innovative combined cycle air-breathing propulsion system, are developed. This thesis work has as first objective the in-depth analysis of the ATR cycle, deepening the development of a tool that allows to describe its performance accurately in various flight regimes. The results will be validated through a comparison with a propulsive database produced by the VKI through advanced analysis tools. Once an effective propulsion model has been defined, the work will continue investigating the effective applicability, to an ATR system, of the emission prediction method known as P3T3, laying the foundations for its adaptation to hydrogen combined cycle hypersonic engines.
