Abstract: An impeller of a centrifugal compressor, the impeller including a web and blades secured to the web on a front face of the web. A point of intersection between a trailing edge and a blade root is at least one half-thickness of the web further forward than the blade root at an intermediate diameter of the impeller, and a point of intersection between the trailing edge and the blade tip is also further forward than the blade tip at an intermediate diameter of the impeller.

Abstract: A turbine engine compressor has at least one annular row of variable-pitch stator vanes that are substantially radial and have pivots at their radial ends. The radially outer pivots of the vanes are received in first openings in a stator casing and the radially inner pivots are received in second openings in a floating ring that surrounds a rotor of the compressor. An annular stator part is inserted between the floating ring and the rotor of the compressor, and first sealing means are mounted between the stator part and the rotor of the compressor. Second sealing means are mounted between the floating ring and the stator part.
