This invention provides an AUV multi-thrust propulsion system, comprising stabilizers, auxiliary rim thrusters, an AUV stern body, main rim thrusters, fairings, connecting discs, and a tail-mounted connecting frame. The main rim thrusters are fixedly connected to the rear end of the AUV stern body via the connecting discs. The fairings are positioned behind the blades of the main rim thrusters. The four auxiliary rim thrusters are uniformly fixed in a cross shape around the circumference of the AUV stern body. The four stabilizers are arranged in an X-shape on the stern body, staggered and evenly spaced with the four auxiliary rim thrusters. The advantages of this invention are increased maneuverability and controllability while reducing the complexity of the drive mechanism, saving stern space, and increasing the power, maneuverability, and system redundancy of the propulsion system by using multiple rim thrusters, thereby improving the safety, stability, controllability, and mission execution efficiency of the AUV in complex underwater environments.
