| 1 | Power will be provided by a single turbofan engine. | |
| 2 | This paper build up a new model of turbofan engine's starting process. | |
| 3 | The effects of thrust vectoring angle and angular velocity of vectoring on turbofan engine operation were investigated. | |
| 4 | The development and design features of the high bypass ratio turbofan engine in foreign are comprehensively summarized. | |
| 5 | The new starting model can be applied to other turbofan engine"s starting processes" numerical simulation and design. |
