Oil-free architecture selection
Compare gas-bearing support concepts against the required load, speed and package envelope.
Oil-free and special-gas rotor systems
Connect the gas-bearing state to the compressor rotor before hardware iteration.
AURA links support geometry, gas state, load, stiffness and flow to the high-speed rotor configuration and the next verification or prototype decision.
Typical decisions
Use one connected model for support, flow and rotor behaviour.
Special-gas operating state
Define pressure, temperature, gas properties and their effect on support performance.
Rotor stability and response
Carry the selected bearing state into the critical-speed and response model.
What to send
Describe the compressor and gas state.
- Compressor type and rotor layout
- Operating and maximum RPM
- Radial, axial and transient loads
- Gas composition, pressure and temperature
- Available bearing and housing envelope
- Flow, leakage or rotor decision required
What comes back
Receive a machine-linked engineering package.
- Candidate support architecture and geometry
- Load, stiffness, flow and operating state
- Support coefficients for the rotor model
- Critical-speed and response consequence
- Defined CFD, sealing, material and test questions
