Abstract
A radial compressor for a compressor arrangement comprising the radial compressor and an axial compressor includes an inlet flow channel bounded by a radially inner hub contour and a radially outer housing contour, in which inlet guide blades are arranged. Via the inlet flow channel a medium to be compressed is supplied to an impeller having moving blades. The inlet flow channel runs diagonally to an axis of rotation of the impeller.
