摘　　要：推进技术的创新曾经是空中运输进步的基本推动力.研制大型客机,必须认识发动机技术进步对飞机性能先进性的重要作用.以用于波音公司B787梦幻飞机的美国通用电气公司(GE)的GEnx发动机为例,分析发动机技术先进性对飞机高效、低污染、智能化、低成本和舒适性的作用.最后从国外的技术发展途径,提出发展我国发动机技术的一些想法.The innovation of propulsion technology used to be and will be continuously to be the primary motive power to the advancement of air transportation. To develop large passenger plane, it is necessary to recognize the role played by the engine technical progress on the advancement of airplane performance. The new engine GEnx for Boeing dreamliner B787 developed by general electric aircraft engines （GEAE） was used as an example to analyze the impact of new engine technology on airplane efficiency, environment pollution, intel-ligent airplane, low cost and comfort of riding. At last, based on the experiences of technical development in foreign countries, some suggestions of the way to develop our engine technology were proposed.
