Preliminary study of the impact of using hydrogen with a fuel cell for aircraft propulsion in an existing platform. En 9th European Conference for Aeronautics and Space Sciences (EUCASS), Lille, France (15 p.)https://hdl.handle.net/11441/155789In the pursue of truly achieving the decarbonisation of air transport, several initiatives have been launched within the aeronautical industry with very different approaches. Despite that many studies have been conducted over the last years, including trials with demonstration flights for fuel cell-based aircraft platforms or for burning hydrogen propulsion, these studies have never gone beyond prototype status. One of the most promising presented alternatives is the incorporation of hydrogen technology in the power plant of flying platforms in order to reduce the carbon footprint. Two ways are contemplated for the introduction of hydrogen technology in the power plant of an aircraft: the burning of hydrogen in a combustion engine and the use of a fuel cell to generate energy to fly. Prior to consider the hydrogen utilization as an alternative, it is necessary to evaluate the impact that such technology might have in aircrafts utilization. The greener option for hydrogen utilization is using a fuel cell as the outcome of the energy production is only water. It is considered in this paper that this impact could be evaluated in the analysis and comparison of the PL (Pay Load) vs. R (range) diagram between two platforms: a traditional platform with engines as Power Plant and a modified platform from that original one using fuel cells and electrical motors as power plant. This article presents a comparison analysis between both platforms by presenting a methodology using preliminary study focused on the cruise phase as it is the more relevant phase to evaluate the range of the aircraft. The direct application of this methodology to a case study will give to the reader the level of the impact of the new technology introduction. Then the optimization in a computational code of this methodology will permit to perform sensitivity studies and to establish metrics and objectives to reduce the impact in the aircraft utilization because of this new technology.application/pdf15 p.engAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.13009/EUCASS2022-7371
