Preliminary analysis of a standard CO2 emissions metric system for a large business jet

The environmental impact of private jets contribute to global aviation emissions, estimated at 3% of total emissions. Private jets, though carrying few passengers, can emit tens of tonnes of CO2 per flight, highlighting the inequality in emissions compared to average global citizens, whose annual carbon footprint is around 4.7 tonnes: already from these figures one can see the importance and necessity of having adequate standard for business aviation. The aim of this thesis is to define the CO2 emission requirements of the Business Jet category, starting from a comparison with the regulations currently in force, specialising in the regulation of emissions from civil aviation aircraft. The regulations in question were issued by ICAO in 2017 and are called Annex 16 - Volume III, “CO2 emission requirements” and provide the entire logical procedure to be used in order to calculate the CO2 metric value of each aircraft to which the regulations refer, also providing the metric limit value not to be exceeded. In order to be able to apply the requirements of the regulations, it was necessary to choose a case study and analyse it both from an aerodynamic point of view - first by applying the Raymer model, then by means of CFD techniques - and from a propulsion and mission point of view. The protagonist of the analysis is Dassault's Falcol 10 X, a latest-generation ultra-long-range jet, which is currently in the production phase and of which, therefore, no emission data is yet available. In any case, even if such data were available, there would be no current standard, regarding emissions from the business jet category, that could decide the suitability of the new jet; the final step of this thesis work is therefore to apply the standard, to see if it can be extended to the case study or, alternatively, to propose analytical reports to be applied in place of those presented in the ICAO document.
