The invention discloses an openable auxiliary propulsion system for an underwater vehicle. The openable auxiliary propulsion system comprises a support, two pairs of propulsion mechanisms and a driving mechanism, and the support is used for being connected with an underwater vehicle cabin; the driving mechanism is arranged on the support, the two pairs of propelling mechanisms are arranged on the driving mechanism, and the driving mechanism controls the two pairs of propelling mechanisms to be synchronously unfolded and folded in the radial direction of the underwater vehicle cabin. Each propelling mechanism is provided with a vertical propeller, and the central axis of the vertical propeller is parallel to the vertical axis of the underwater vehicle cabin. The openable auxiliary propulsion system for the underwater vehicle serves as an auxiliary propulsion system during maneuvering and precise operation of the underwater vehicle, and can be retracted into a cabin body when the underwater vehicle is in direct navigation or needs to shuttle in complex submarine terrains, so that the appearance smoothness of the cabin body of the underwater vehicle is guaranteed, the shape resistance is reduced, the cruising ability is greatly improved, and the underwater vehicle can be used as an auxiliary propulsion system for underwater vehicle maneuvering and precise operation. And meanwhile, the passing performance of the underwater vehicle in complex seabed terrains is ensured.
