ABSTRACT:
A variable-geometry turbocompressor is provided which includes a tandem variable stator downstream of a rotor stage. The tandem stator includes an inlet stator cascade and an outlet stator cascade arranged adjacent one another and each including variable guide vanes. To accommodate precise control of the air flow over various compressor operating conditions, the inlet and outlet stator cascades are provided with adjusting mechanisms for varying the position of their vanes independently of one another.
