The invention provides an electric control variable pitch propeller, which comprises a main shaft, variable pitch blades and a brake module, and is characterized in that the main shaft comprises a vertical rod and a transverse rod which are vertically arranged; the braking module comprises a magnet exciting coil, a braking eddy current disc and a braking gear which are coaxially arranged, and the braking eddy current disc and the braking gear are installed on the vertical rod; the variable-pitch blades comprise variable-pitch bevel gears and blades connected with the variable-pitch bevel gears, and the variable-pitch bevel gears are connected with the transverse rod and meshed with the brake gear. The invention further provides a multi-axis aircraft. The multi-axis aircraft comprises a main body and at least two electric control variable pitch propellers. The invention further provides a control method of the multi-axis aircraft. Under the condition that a series of mechanical transmission structures such as a steering engine and a pull rod are not adopted, variable-pitch control is achieved through meshing of the brake gear of the brake module and the variable-pitch bevel gear of the variable-pitch blade, and then the requirement for attitude control is met.

    本发明提供一种电控变距螺旋桨,包括主轴、变距桨叶及制动模组,其中:所述主轴包括垂直设置的立杆与横杆;所述制动模组包括同轴设置的励磁线圈、制动涡流盘和制动齿轮,且所述制动涡流盘、制动齿轮安装在所述立杆上;所述变距桨叶包括变距锥齿轮及与所述变距锥齿轮相连的桨叶,所述变距锥齿轮与所述横杆相连且与所述制动齿轮相啮合。本发明还提供一种多轴飞行器,包括主体及至少两个上述的电控变距螺旋桨。本发明还提供一种多轴飞行器的控制方法。本发明在不采用舵机和拉杆等一系列的机械传动结构的情形下,通过制动模组的制动齿轮与变距桨叶的变距锥齿轮相啮合实现变距控制,进而满足姿态控制的需要。
