First support architecture
Select journal, thrust, conical or combined support for the required speed and load state.
Cryogenic and special-gas rotor systems
Carry the temperature-dependent support state into the rotor decision.
AURA structures the gas-bearing geometry, clearance, pressure and stiffness state so the rotor model can be evaluated at the machine conditions that matter.
Typical decisions
The operating state changes the support and the rotor together.
Warm-to-cold transition
Track how clearance, gas state and support coefficients move across thermal conditions.
Rotor consequence
Carry each selected support state into critical-speed and response analysis.
What to send
Define the operating envelope.
- Rotor layout, mass and inertia basis
- Operating and maximum RPM
- Radial, axial and transient loads
- Gas type, pressure and temperature states
- Warm and cold geometry or clearance basis
- Required machine decision
What comes back
Receive state-linked support and rotor results.
- Candidate support architecture and geometry
- Operating-state load, stiffness and flow results
- Support coefficients for selected thermal states
- Critical-speed and response consequence
- Defined CFD, material, sealing and test questions
State chain
One calculation record for each machine condition.
01
Thermal state
Temperature, pressure, gas properties and geometry.
02
Bearing state
Clearance, load, stiffness, damping and flow.
03
Rotor state
Critical families, response and operating margin.
04
Next engineering action
Refine geometry, verify locally or prepare the test programme.
Relevant capability
Analytical selection first, higher-fidelity verification where it adds value.
AURA support synthesis
Generate and compare support candidates under the defined state.
Open AURA →Gas-bearing rotor dynamics
Carry the selected support coefficients into the machine-level model.
Open rotor route →CFD verification pilot
Resolve local pressure and velocity fields after the candidate is selected.
Open CFD route →Send one cryogenic rotor state.
Start with speed, loads, gas conditions, thermal states and the decision required.
