Description

technical field

[0001] The invention relates to a spherical vector nozzle device adopting a double hydraulic symmetry system, which belongs to the technical field of the shipbuilding industry. Background technique

[0002] Vector water-jet propulsion technology is widely used in shipbuilding industry navigation, amphibious military equipment and other fields. It mainly uses the reaction force of the water sprayed by the water jet propulsion pump installed in the hull to push the ship forward, and realizes the vector control of the direction of the water flow by controlling the mechanical mechanism arranged near the nozzle, so as to realize the control of the ship. At present, the mechanisms for changing the course of ships mainly include: rudder surface mechanism, multi-propeller structure, bionic fin mechanism, omnidirectional propulsion mechanism, vector propulsion mechanism, etc. Among them, the vector propulsion mechanism can directly change the direction of propulsion f...
