The next steps for Airbus' big bet on open rotor engines
Summary
Airbus is pursuing open rotor engines as a potential path to significantly higher fuel efficiency, with the RISE program involving GE and Safran. The article outlines testing plans (wind tunnels, ground tests, and eventual flight tests), possible engine placements, and safety/noise considerations, while noting that Airbus is also evaluating alternative configurations with other suppliers and that the open rotor is not yet a guaranteed path. Industry voices acknowledge potential benefits but emphasize ongoing engineering, regulatory, and market uncertainties.
