COMPARISON OF MODELS TO PREDICT LOW ENGINE ORDER EXCITATION IN A HIGH PRESSURE TURBINE STAGEumber and pressure are computed with poor agreement to experiments. Future evaluations of the resulting rotor excitation pressure are needed to estimate the level of necessary agreement to give acceptable predictions of the low engine order forced response.

STRUCTURE OF UNSTEADY VORTICAL WAKES BEHIND BLADES OF MUTUAL-MOVING ROWS OF AN AXIAL TURBOMACHINEssing waves of vorticity causes acoustic disturbances and additional aerodynamical losses owing to energy dissipation. As dissipative function depends on distribution of vorticity, for an estimation of the losses, caused a rotor-stator interaction, the description of vortical wakes structure at presence in them of free vortexes is necessary.
