Within the scope of European Commission FP7 project FACTOR, dedicated to combustor-
turbine-interaction research, a clean-sheet design of a rotating turbine test rig featuring a
non-reacting combustor simulator was created and built among the partners. German
Aerospace Center DLR provided the operational facility NG-Turb to which the rig was
adapted and was responsible for global rig integration and operation, also including
aerodynamic probe measurements of the flow field. The rig and experimental set-up is …

Reducing the uncertainties in the prediction of turbine inlet conditions is a crucial aspect to
improve aero engine designs and further increase engine efficiencies. To meet constantly
stricter emission regulations, lean burn combustion could play a key role for future engine
designs. However, these combustion systems are characterized by significant swirl for flame
stabilization and reduced cooling air mass flows. As a result, substantial spatial and
transient variations of the turbine inlet conditions are encountered. To investigate the effect …
