Multi-propeller propulsion simulation system for vessel

The invention relates to the field of combined power propulsion control of a vessel, in particular to a multi-propeller propulsion simulation system for a surface vessel. The multi-propeller propulsion simulation system for the surface vessel comprises multiple propeller propulsion simulation devices, a real-time simulator and an upper computer, wherein the multiple propeller propulsion simulation devices are connected with the real-time simulator, the real-time simulator is connected with the upper computer, and multi-propeller simulation of the vessel and simulation of four-quadrant hydrodynamic characteristics of the propellers are realized through data exchange of all parts.
