The effectiveness of the Vectored Thrust Ducted Propeller (VTDP) system is not high currently, especially the lateral force is not large enough. Thus, a conceptual design for a deflection device of a VTDP system was proposed to achieve effective hovering control. The magnitude of the lateral force that was applied to maintain balance while hovering was examined. A comparison between the experimental and numerical results for the 16H-1 was made to verify the numerical simulation approach. The deflection devices of the X-49 and the proposed design were analyzed using numerical simulations. The results indicated that a larger lateral force and lower power consumption were presented in the proposed design. The results of this article provide a new idea for the design of the VTDP system.

VTDP系统中偏转装置的概念设计

矢量推力螺旋桨系统（VTDP）的效率目前不高，尤其是侧向力不够大。因此，提出了用于VTDP系统的偏转装置的概念设计，以实现有效的悬停控制。检查了用于在悬停时保持平衡的侧向力的大小。对16H-1的实验结果和数值结果进行了比较，以验证数值模拟方法。使用数值模拟分析了X-49的偏转装置和提出的设计。结果表明，提出的设计提出了更大的侧向力和更低的功耗。本文的结果为VTDP系统的设计提供了新思路。
