The invention discloses a dynamic similarity design method for a self-propelled model of an ultra-high-speed planing boat, and relates to the technical field of ships, the method comprises the following steps: after the self-propelled model is manufactured, estimating a model power system according to still water dragging test data, and then respectively carrying out a static motion test and a dynamic sliding test on the self-propelled model carrying the model power system; the method comprises the steps of obtaining a change curve of a throttle lever control position along with time, a change curve of a navigational speed along with time and a relation curve of the throttle lever control position and static thrust, then determining a static thrust correction coefficient through a data analysis method to be used for correcting the static thrust of a self-propulsion model, and then carrying out dynamic similarity design directly according to a thrust similarity criterion. The precision and the practicability of the dynamic similarity test of the self-propelled model of the superspeed planing boat can be improved, and the design requirements of a real boat of the superspeed planing boat and a power system of the self-propelled model can be met.
