Abstract
An axial flow compressor including one or more axially spaced stator sections (14) each having a circumferential array of guide vanes (15), and one or more rotor section (12, 16) each having a circumferential array of rotor blades (13, 17; A, B), and between successive rotor blades (A, B) there are formed flow paths and between the stator and rotor sections there are provided axial gaps (22, 23, 24) of a diverging configuration so as to form in each flow path a diffusion region (C) which extends from a narrowest cross section (a.sub.2) of the flow path located at a certain distance upstream of the leading edge of a second rotor blade (B) to a wider cross section (a.sub.3) located approximately at the leading edge of the second rotor blade (B), wherein each flow path has a transition region (D) of a substantially non-increasing cross sectional area extending from the wider cross section (a.sub.3) to the trailing edges of the rotor blades (A, B).
