Fuel consumption evaluation of an UHBPR turbofan during cruise

Currently, the aviation industry, both civil and military, plays a major role in global greenhouse gas emissions. During the 77th IATA (International Air Transport Association) Annual Meeting Group (AGM) the airlines established a net-zero carbon emissions target within the 2050. In this scenario, minimizing the fuel consumption becomes the main driving factor during the design process of a jet engine. High-Bypass Ratio Turbofans have proven to be prime candidates for achieving this important goal: their high propulsive efficiency allows them to significantly reduce fuel consumption while still providing the required thrust to keep the aircraft at high altitude. The Ultra High-Bypass Ratio represents the next frontier for this kind of configuration, its incredible performances are achieved using the best technologies available on the market right now. Precisely in this perspective, this thesis aims to analyse the fuel consumption of an UHBPR Turbofan in order to evaluate its behaviour during a typical cruise mission . The engine is mounted on the Common Research Model and its performances are evaluated using GasTurb 14. Fluent is the solver selected for the analysis.
