DEFINITION:

The calibration of a test bench consists of determining all the losses due to the test cell configuration affecting the engine performances (thrust, ..).

The calibration of the test cell must be determined for a given engine configuration.

SUBDOMAINS:

The resulting corrective factors are determined to take into account:

1. the energy loss due to the boundary layers in the vicinity of the test cell walls
2. the heterogeneity of the flow field upstream the engine inlet
3. the aerodynamic forces on the mechanical system maintaining the engine
