作为民用飞机,航行于人口密集的各大城市之间,噪声、污染、破坏丁宁静环境,导致生态失衡,尤其当代。如果噪声与污染未获解决,民机将失去其发展的立足点. 民机的噪声、污染来源其动力。早在60年代末,民用客机的发展,就对发动机的选择提出一系列要求,噪声、污染则首当其冲。CFM56发动机针对这一要求,研制并获成功. As a civilian aircraft, sailing between densely populated cities, noise, pollution and destruction of the quiet environment lead to ecological imbalances, especially in the contemporary era. If the noise and pollution have not been resolved, civil aircraft will lose its foothold in the development of civil aircraft noise and pollution sources of its power. As early as the late 1960s, the development of civilian passenger planes raised a series of demands on the choice of engines. Noise and pollution were the primary ones. CFM56 engine in response to this request, developed and successful.
