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
intelligent 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.
