The invention belongs to the technical field of underwater weapons and ocean engineering, and particularly relates to an AUV (autonomous underwater vehicle) propulsion system which comprises a watertight motor, a propulsion propeller and a fairing, the watertight motor is mounted at the front end of an autonomous underwater vehicle shell, the propulsion propeller is mounted at the front end of the watertight motor, the fairing is fixed on the periphery of the watertight motor, and a watertight closed space is formed between the fairing and the autonomous underwater vehicle shell. The watertight motor in the AUV propulsion system is designed and used, and a propulsion motor can be completely watertight and has thrust characteristics. Different from other motors, the propulsion motor is completely watertight when applied to the AUV propulsion system and can be applied to similar propulsion system motor design occasions by the aid of stepped pressure drop dynamic sealing technology.
