  • Aero-acoustic experimental characterization of a CROR (Contra Rotating Open Rotor) engine WT model with core flow in propellers architecture

The CROR engine architecture with primary flow ejection into propellers is a promising technology to reduce CROR engine weight. Unfortunately, state-of-the-art numerical methods are not mature enough to predict the impact of this technology on broadband noise. Wind-tunnel test is then necessary to assess the noise.  Please refer for the full and formal topic description to Annex III of the Clean Sky 2 Work Plan 2014-2015 Amendment nr. 1  Version 3 (see under the tab "Topic Conditions and Documents")
