    The invention provides a method for determining main parameters of a ship water-jet propeller, and belongs to the technical field of underwater propulsion. The determination method comprises the following steps: determining the influence factor, and determining an assumed value of the influence factor; according to a water jet propulsion theory and the assumed value of the influence factor, obtaining an assumed value of a main parameter of the ship water jet propeller; based on the assumed value of the main parameter, correcting the assumed value of the influence factor to obtain a corrected value of the influence factor; based on the correction of the influence factor, correcting the assumed value of the main parameter to obtain a corrected value of the main parameter; continuously iteratively correcting the correction value of the main parameter and the correction value of the influence factor until the correction value of the main parameter is within a set numerical range; and taking the correction value of the main parameter in a set numerical range as the design main parameter of the ship water-jet propeller. According to the invention, the precision of the main parameter can be improved.
