    What is open rotor technology development?
    In partnership with NASA and the FAA, the five-year, two-phase open rotor technology development program has demonstrated the aggressive performance and acoustic goals established at the beginning of the technology development program. The goals were derived from the anticipated fuel burn and noise requirements of future narrow body aircraft.
