现代小型涡扇发动机的三个特点

Design Features of Modern Small Turbofan

目前航空公司要求新一代支线飞机飞的更快、更高、燃油效率更高和经济性更好。如庞巴迪公司的“挑战者”604、美国赛斯纳公司的“奖状”加大航程型等飞机都是其现有设计的改进型。它们的改进在很大程度上均依赖于其动力装置技术的改进。这种新的动力装置又是通过增大空气流量、提高压比和加大温度裕度来达到飞机要求的。

Now airlines require the faster and higher flying, more fuel efficient, and more economical regional aircraft. The aircraft mainly depend upon the small turbo-fan ' s improvement. The paper introduces that the requirements are met by increasing in the airflow, overall pressure ratio and temperature margin of the engines.
