Zusammenfassung:	The present invention relates to an aircraft ram jet engine for supersonic and/or hypersonic flight, intended to operate over a wide range of speeds. According to the invention, the ram jet engine comprises a ram jet engine body (5) including a combustion cheer portion (6) and a jet pipe portion (7), and, in the vicinity of the transition region (8) between the combustion chamber (6) and the jet pipe (7), having a changing geometry passing progressively from a convergent then divergent longitudinal section, for speeds corresponding to a low Mach number, to an at least substantially constant then divergent longitudinal section for speeds corresponding to a high Mach number.
