The invention provides a tiltable ducted lift fan. The tiltable ducted lift fan comprises two propeller blade sets, a supporting column, a ducted shell, a gear box, a transmission shaft, a tilting shaft, a tilting torque input gear, a rotating torque input gear and a transmission main gear. The gear box is arranged in the center of a duct formed by the ducted shell. The tilting shaft is a hollow shaft, the two propeller blade sets are symmetrically arranged at the upper end and the lower end of the gear box. Each propeller blade set is connected with a transmission driven gear in the gear box,the upper transmission driven gear and the lower transmission driven gear are both meshed with a transmission main gear, the transmission main gear is fixed to one end of the transmission shaft, andthe other end of the transmission shaft penetrates through the outer wall of the gear box and the tilting shaft and then is connected with the rotating torque input gear. One end of the tilting shaftis fixed to the outer wall of the gear box, the other end of the tilting shaft penetrates through the duct shell and then is supported by a first fixing support, and the other end of the tilting shaftis connected with the tilting torque input gear. The tiltable ducted lift fan is direct and sensitive in reaction, and an aircraft can fly more flexibly and stably.

    本发明提供了一种可倾转涵道升力风扇,包括两组螺旋桨叶组、支柱、涵道外壳、齿轮箱、传动轴、倾转轴、倾转力矩输入齿轮、转动力矩输入齿轮和传动主齿轮;齿轮箱设置在涵道外壳形成的涵道的中心位置,倾转轴为空心轴,两组螺旋桨叶组对称设置在齿轮箱的上下两端,每一组螺旋桨叶组与齿轮箱内一传动从齿轮相连,上下两个传动从齿轮均与传动主齿轮相啮合,传动主齿轮固定在传动轴的一端,传动轴的另一端穿过齿轮箱的外壁、倾转轴后与转动力矩输入齿轮相连;倾转轴的一端固定在齿轮箱的外壁上,倾转轴的另一端穿过涵道外壳后通过第一固定支架支撑,倾转轴的另一端与倾转力矩输入齿轮相连。本发明反应直接、灵敏,可以使飞行器飞行更灵活、更稳定。
