An electric contra-rotating ducted fan power module with a vector control surface comprises a ducted shell, a contra-rotating fan, a main shaft, a motor, a steering engine, the vector control surface and a stabilizing surface. The main shaft is located in the middle in the duct shell. The duct shell is connected with the aircraft through a rotating shaft; the stabilizer is located at the duct outlet; the two contra-rotating fans are driven by a motor to rotate in opposite directions; the vector control surface is located outside the stabilizer at the outlet of the duct, and the two ends of the vector control surface are connected with the steering engine and the stabilizer respectively. The counter-rotating fan is used for counteracting the reaction torque generated by a single fan, meanwhile, the first-stage fan and the second-stage fan are used for accelerating airflow twice, then high-speed airflow and a deflection vector control surface are formed at the outlet position of a duct to form control torque, attitude control is conducted, and a traditional control surface of an aircraft can be replaced. The power system has the advantages of compact structure, high thrust-weight ratio, control redundancy and high control efficiency, can be combined and matched with a take-off and landing aircraft for use through modular design, and is high in universality.

    一种带矢量舵面的电动对转涵道风扇动力模块,包括涵道壳体、对转风扇、主轴、电机、舵机、矢量舵面和安定面;主轴位于涵道壳体内的中部;涵道壳体通过转轴和飞行器连接;安定面位于涵道出口处;对转风扇设有两个并通过电机驱动形成反向旋转;矢量舵面位于涵道出口处安定面的外侧,矢量舵面的两端分别与舵机和安定面连接。利用对转风扇,将单个风扇产生的反扭矩抵消,同时利用第一级风扇和第二级风扇对气流两次加速后在涵道出口位置形成的高速气流,偏转矢量舵面形成控制力矩,进行姿态控制,可代替飞行器传统操纵面。该动力系统具有结构紧凑,推重比高,控制冗余和控制效率高的优点,经过模块化设计,可组合搭配起降飞行器使用,通用性高。
