  • The efficiency of a pulsed detonation combustor-axial turbine integration 
    Xisto, Carlos M.; Petit, Olivier; Grönstedt, Tomas; Rolt, Andrew Martin; Lundbladh, Anders; Paniagua, Guillermo (Elsevier, 2018-09-05)
    The paper presents a detailed numerical investigation of a pulsed detonation combustor (PDC) coupled with a transonic axial turbine stage. The time-resolved numerical analysis includes detailed chemistry to replicate ...
  • Enabling cryogenic hydrogen-based CO2-free air transport: meeting the demands of zero carbon aviation 
    Sethi, Vishal; Sun, Xiaoxiao; Nalianda, Devaiah; Rolt, Andrew Martin; Holborn, Paul; Wijesinghe, Charith; Xisto, Carlos; Jonsson, Isak; Grönstedt, Tomas; Ingram, James; Lundbladh, Anders; Isikveren, Askin; Williamson, Ian; Harrison, Tom; Yenokyan, Anna (IEEE, 2022-06-02)
    Flightpath 2050 from the European Union (EU) sets ambitious targets for reducing the emissions from civil aviation that contribute to climate change. Relative to aircraft in service in year 2000, new aircraft in 2050 are ...
  • Preliminary analysis of compression system integrated heat management concepts using LH2-based parametric gas turbine model 
    Abedi, Hamidreza; Xisto, Carlos M.; Jonsson, Isak; Grönstedt, Tomas; Rolt, Andrew Martin (MDPI, 2022-04-14)
    The investigation of the various heat management concepts using LH2 requires the development of a modeling environment coupling the cryogenic hydrogen fuel system with turbofan performance. This paper presents a numerical ...
  • Scale effects on conventional and intercooled turbofan engine performance 
    Rolt, Andrew Martin; Sethi, Vishal; Jacob, Florian; Sebastiampillai, Joshua; Xisto, Carlos M.; Grönstedt, Tomas; Raffaelli, Lorenzo (Cambridge University Press, 2017-06-08)
    New commercial aero engines for 2050 are expected to have lower specific thrusts for reduced noise and improved propulsive efficiency, but meeting the ACARE Flightpath 2050 fuel-burn and emissions targets will also need ...
  • Synergistic technology combinations for future commercial aircraft using liquid hydrogen 
    Rompokos, Pavlos; Rolt, Andrew Martin; Nalianda, Devaiah; Isikveren, Askin T.; Senné, Capucine; Grönstedt, Tomas; Abedi, Hamidreza (American Society of Mechanical Engineers, 2021-01-11)
    Liquid hydrogen (LH2) has long been seen as a technically feasible fuel for a fully sustainable greener aviation future. The low density of the cryogenic fuel would dictate the redesign of commercial aircraft to accommodate ...
