Abstract: Scimitar is a hypersonic air-breathing engine, which allows for active compression through the use of advanced heat exchangers.The Mach number limitation associated with gas turbines can therefore be overcome by "precooling" the inlet air prior to compression.Hydrogen fuel is used as a heat rejection sink in a complex thermodynamic cycle to allow the incoming air to be cooled adequately; the actual cycle working fluid is high-pressure helium, a good heat and work transfer medium.In what follows, the theory behind the thermodynamic cycle is presented, together with the practical technology being developed to prove and explore Scimitar's feasibility.
