Description

technical field [0001] The invention belongs to the technical field of submarines, and in particular relates to a self-coupling ship submersible pump jet propulsion device which replaces propellers. Background technique [0002] Submarines have powerful attack power, unique concealment and mobility, can stay away from the base for a long time, and have the ability to cooperate with other forces in the naval formation to carry out various combat missions. Therefore, they have always been the focus of fierce competition among naval powers in the world. . However, once the submarine's whereabouts are exposed, it will lose its inherent advantages, be easily tracked and attacked by the enemy, and its survivability will be greatly reduced. With the rapid development of acoustic detection technology, how to reduce radiation noise and reduce the probability of being discovered by enemy sonar has become a key research topic of nuclear submarine technology. [0003] The propulsion t...
