High-power propeller with compact structure

The invention relates to a high-power thruster with a compact structure. The high-power thruster comprises a guide pipe, a first motor, a second motor, a first propeller, a second propeller and a rotating shaft, the first motor is installed at the front end of the guide pipe, and the second motor is installed at the rear end of the guide pipe and sleeved with the rear end of the first motor. The first propeller is fixedly connected with the first motor, and the center of the first propeller fixedly sleeves the front end of the rotating shaft; the second propeller is fixedly connected with the second motor, and the center of the second propeller fixedly sleeves the rear end of the rotating shaft; a first arc surface is arranged on the inner wall of the first propeller. The rear end of the first motor is sleeved with the second motor, so that the size of the propeller is reduced while the same pushing force is ensured; due to the arrangement of the first cambered surface and the second cambered surface, the rot
