The overall thrust was also reduced, from 24,000 to 20,000 lbf (107 to 89 kN), mostly due to the reduction in bypass ratio.[24]【参考译文】在20世纪80年代初,波音公司选择了CFM56-3作为波音737-300变体的独家动力源。737的机翼离地面的距离比CFM56之前的其他应用更近,这要求对发动机进行几项修改。
Leading particulars for the -7/B18 are: bypass ratio 5.5, overall pressure ratio 32.7, airflow 677lb/s, net thrust 19500lbf. The CFM56-5B/5C/7 use essentially the same HP core. HP parts are dimensionally identical among the 5B/5C/7 although may or may not have different part numbers ...
