Clean Sky 2 Call for Proposals 01 · Aero-acoustic experimental characterization of a CROR (Contra Rotating Open Rotor) engine WT model with core flow in propellers architecture

Scope: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 necessa…
