Aircraft Engine Case
- Rotor-stator contact leads to highly unstable vibrations that had to be avoided.
- Large gap necessary to avoid contact translates to higher fuel consumption.
- Lower performance
The rotor-stator contact was already identified as problem root cause but without ways to investigate and master the resulting vibrations.
Accurate characterization of the nonlinear vibration and creation of a model that can reliably account for it. This model can then be used to develop robust designs allowing reduced gaps and the occurrence of contact without putting the structure’s integrity at risk.
Performance gain through higher fuel efficiency.
