For heavy torpedoes with conventional tail fin and rudder layout, when the navigation speed is low, the surface velocity is too low to produce enough lift on the fin and the rudder may be unstable and sinking. The vector propulsion technology has significantly improved the low-speed stability of the torpedo and made it possible to maneuver the mine body at a large angle of attack. This subject adopts a new multi-degree-of-freedom vector rudder control + integrated motor technical solution to study the overall layout of the vector propulsion system, transmission mechanism layout, vector transmission mechanism, propeller design, torpedo fluid parameter prediction and handling stability analysis, vector control mechanism and control Technical research on strategies, etc., completed the trial production and test verification of the vector propulsion power plant prototype, and completed the ducted propeller open-water model and self-propelled model tests. After the next step of engineering optimization, it can be used in underwater vehicle power plants, especially modular torpedo power plants and military-grade UUV power systems, which have great market potential and prospects in China.
