CROR blade deformation, part 1: Experimental results by strain pattern analysis
Résumé
Although contra-rotating open rotors (CROR) were experimented mainly in the 40’s, even limitedly produced in some countries, and with enhanced performances compared to single propellers, their complex design, installation and maintenance prevented them from being used over an extended period of time. The current research by aeronautical community on bringing significant step changes regarding the environmental impact of aviation has given new impetus to this kind of propulsion system. Within the CleanSky SFWA-ITD project, recent wind tunnel tests campaigns have been performed to get a deeper understanding of the complex phenomena involving aerodynamic, acoustic, structural, performances, and aeroelastic topics.
