This project focus on a breakthrough in low noise and low emission engine

architectures. VITAL will achieve this breakthrough by bringing together 53 actors

from the leading European engine manufactures

Objective of this project is a detailed investigation of the stator-rotor-stator

interaction in a transonic turbine stage. The outcome of this work is a experimental

database for unsteady, transonic flows through a high pressure turbine 1 ½ stage.
