Power plant has compressor, gas generating stage and power stage each with screw rotor pair driven by control transmissions, consequently screw rotor pairs run contactless and form narrow labyrinth sealing gap

摘要

The power plant is divided into a compressor, several combustion chambers, a gas generating stage and a power stage. The power plant is enclosed by a cooled casing, the compressor is directly coupled to the gas generating stage, and power stage is free wheeling. The compressor, gas generating stage and power stage each have a screw rotor pair (6,7,8). Control transmissions drive the screw rotor pairs and consequently the screw rotor pairs run contactless and form a narrow labyrinth sealing gap.
