As part of the Brite/EuRam project "Aeroelastic Design of Turbine Blades II" (ADTurBII) Low Engine Order (LEO) experiments in a high pressure turbine stage with stator coolant flow and throat area variation were carried out in the windtunnel for rotating cascades (RGG) at DLR in Goettingen. In order to adjust the boundary conditions for these experiments and to ensure, that the turbine stage is running at the desired operating points, a throughflow code has been written and a throughflow analysis for the DLR rig was performed. The affect of LEO changes of the nozzle guide vane arrangement around the stator ring onto the basic flow properties of the stage was then assessed. Additionally stage performance parameter were calculated for all operating points and compared with ADTurB results.
