System Overview
The Compressor Assembly is the first energy‑transfer stage within the CCAMTG‑2500™ architecture. It
increases the pressure of the working fluid before delivery to the pressure vessel and turbine stages.
The subsystem is organized to support:
- Independent servicing
- Simplified inspection
- Repeatable assembly
- Integration with magnetic bearing support
- Compatibility with adjacent assemblies
Compressor Functional Description
The compressor subsystem performs the following conceptual functions:
- Receives conditioned airflow from the intake system
- Increases working‑air pressure through staged compression
- Delivers compressed air to the pressure vessel
- Minimizes flow separation and turbulence
- Supports stable rotor operation
- Interfaces with cooling and instrumentation systems
The compressor is supported by the shaft and magnetic bearing system to maintain concentric operation
within the housing.
