Airflow characterization through rotating labyrinth seal

The aim of this project is to test different configurations of labyrinth seals to determine the pressure loss characteristics for different rotor speeds and different radial clearances. The test rig shall be able to test only a seal configuration in a simplified environment (see figure 4). Safran Aircraft Engines will design the seals and the partner will manufacture the seals, design and assembly the test vehicle, conduct the test campaign and analyse the results. This results shall be compared with the present numerical model predictions in order to perform a gap analysis. If the calculations do not match with the test results then we expect the partner to propose improvements to our existing model. Please refer to the full topic descriptions document published in this call.
