Dynamic Simulation of the Turning Transient Process of Waterjet Propulsion Warship

The mathematical modeling of the propulsion system of waterjet propulsion warship and dynamic simulation of the turning transient process are presented in the paper. First, the methods for building the mathematical models and simulative models of the propulsion system of a certain waterjet propulsion warship are introduced; and then, based on the simulative models above, the turning transient of the warship is studied by using the simulation, and the changing rules of the performance parameters including warship velocity, diesel load, working safety of waterjet pump under different turning courses are gained, the conclusions derived form which are very helpful for us to understand the matching relationship among hull, engine and pump in a waterjet propulsion warship under turning transient process. Furthermore, the conclusions also have an instructive meaning for the scientific prediction of maneuverability performance and the corrective development of controlling parameters under the turning course of the warship.
