The SILENT consortium gathered in Florence at ERGON’s premises for its 4th General Assembly

Over two days, partners reviewed progress, aligned on the next steps, and further strengthened collaboration across the different work packages. Key technical developments were presented, including ongoing work on nozzle and facility design.

Thanks to newly developed design methodologies and advanced control techniques, the SILENT nozzle is expected to operate in quiet conditions at Reynolds numbers significantly higher than those currently achieved worldwide, exceeding transition Reynolds numbers encountered in flight conditions. This would open new perspectives for the study of transition across a wide range of cases, as well as high-Reynolds-number turbulence in a controlled low-noise environment.

We thank the ERGON team for their hospitality, as well as all consortium members for their continued commitment and collaboration in advancing the SILENT project: ONERA, German Aerospace Center (DLR), von Karman Institute for Fluid Dynamics, MBDA, and ABGi France.
