| 摘 要： | 针对带变向环涵道风扇矢量推进（VTDP）系统，使用FLUENT结合动量源方法对其流场和气动特性进行分析，研究了该系统各偏转部件在不同偏转角度组合状态下对系统气动特性的影响。计算结果表明变向环可以有效地将涵道风扇产生的部分拉力转变为侧向力，同时还可以提高风扇产生的拉力；但偏转量过大会加快系统迎风阻力的增大。

| Abstract: | A geometric model for the vectored thrust ducted propeller with sectors （VTDP） system was developed in this paper. Then based on FLUENT and momentum- source method, the flow field and aerodynamic characteristics of the model was analyzed. For the deflection components of the system in the state of different deflection combination, the impact of the aerodynamic characteris- tics was investigated. Calculation results show that sectors can convert partial thrust force to yawing force and improve the thrust force produced by propeller. However, a large deflection angle of sec- tors made the drag force increases faster. |
