On-wing designs

摘要

Airlines want the next gen-eration of engines to have a 20% lower cost of ownership, 30% fewer emissi6ns, half the existing noise footprint around airports, and to be essentially maintenance-free, with no in-flight shutdowns or engine problems that result in delayed flights and cancellations. For propulsion engineers, the way forward is attacking those challenges with a three-pronged approach that simultaneously addresses engine reliability, fuel efficiency, and life-cycle costs.
