Abstract
The process can include: scanning the vane ring, including creating a tri-dimensional digital model of the vane ring in an initial configuration; performing a computerized simulation of airflow across the vane ring based on the tri-dimensional digital model; identifying one or more flow discrepancy based on the computerized airflow simulation; associating a subset of one or more vanes of the set of vanes to the one or more flow discrepancy; and plastically deforming at least one vane of the subset.
Claims20
A process of preparing a vane ring of a gas turbine engine, the vane ring having a set of vanes, the process comprising:
- creating a tri-dimensional digital model of the vane ring in an initial configuration, the creating including scanning the vane ring in the initial configuration;
- using the tri-dimensional digital model, performing a computerized simulation of airflow across the vane ring in the initial configuration;
- identifying a flow discrepancy associated with the vane ring based on results of the computerized simulation;
- and
- associating a subset of one or more vanes of the set of vanes to the flow discrepancy.
A method of reworking a vane ring of a gas turbine engine, the method comprising:
- based on a tri-dimensional digital model of the vane ring, performing a computerized simulation of airflow across the vane ring;
- identifying a flow discrepancy pertaining to a pair of adjacent vanes of the vane ring based on the computerized simulation including comparing a value acquired from the computerized simulation to a criterion;
- and
- plastically deforming at least one vane of the pair of adjacent vanes.
A system for preparing a vane ring, the system comprising:
- a processor;
- and
- a non-transitory machine-readable memory operatively connected to the processor, and storing:
- a tri-dimensional digital model of the vane ring;
- correlation data associating effective flow area and air mass flow;
- and
- instructions executable by the processor and configured to cause the one or more processor to:
- perform a computerized simulation of airflow across the vane ring based on the tri-dimensional digital model including computing an effective flow area of the vane ring and determining air mass flow across the vane ring based on the correlation data;
- identify a flow discrepancy based on the computerized simulation;
- and
- associate a subset of one or more vanes of a set of vanes of the vane ring to the flow discrepancy.
