Suitable for Chinese First Jetliner C919, the high bypass ratio turbofan engine strictly follows the civil aviation airworthiness standards and its noise and emission meet the requirement of current airworthiness rules. The whole performance aims to compete with the most advanced Leap Engine at present. The program is divided into 5 phases, including requirement analysis and definition, concept design, preliminary design, detail design and test and verification. The success in concept design appraisal indicates that passing through technical identification stage, the program of Chinese Jetliner power plant enters into engineering developing stage.
