| Abstract: | Result of test research on aerodynamic behaviour of the DF-9 type locomotive engine and its retrofit proclaim, the leading shape of locomotive engine is an important foctor of af-fecting scale of the aerodynamic drag. Furthermore, it also affects the drag coefficient of the dou-bledecker carriage. Some methods of reducing drag, such as the apron etc, the drag can be reduced obviously. |
