与2000年的飞机相比，2020年投入使用的下一代飞机有可能实现航程增加50%或燃料消耗减少30%。复合材料和推进技术的进步是主要的性能贡献因素。推进系统的效率将对总燃料消耗的减少做出最大贡献。本文考察了获得这一性能的参数，并评估了各种推进配置的相对优点。评估了比油耗、重量、声学和可靠性等技术参数。比较了涡轮风扇和涡轮螺旋桨风扇在单转和对转两种构型下的安装效果。收购和直接运营成本也被考虑在内。
Next generation aircraft entering service in 2020 have the potential to achieve range increases of up to 50% or reductions in fuel burn of up to 30% relative to a Year 2000 airplane. Advances in composites and propulsion technologies are the primary performance contributors. Propulsion system efficiencies will contribute most of the total fuel burn reduction. This paper examines the parameters that obtain this performance and assesses the relative merit of various propulsion configurations. Technical parameters of specific fuel consumption, weight, acoustics, and reliability are evaluated. Turbofans are compared to turbopropfans in both single and counterrotating configurations and installation effects are examined. Acquisition and direct operating cost are also considered.
