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.

    本申请公开了一种超高速滑行艇的自航模型动力相似设计方法,涉及船舶技术领域,该方法在制作自航模型后,根据静水拖曳试验数据估算模型动力系统,然后对搭载模型动力系统的自航模型分别开展静态运动试验和动态滑行试验,以得到油门杆操纵位置随时间的变化曲线、航速随时间的变化曲线以及油门杆操纵位置与静推力的关系曲线,继而通过数据分析方法确定静推力修正系数用于修正自航模型的静推力,然后直接按照推力相似准则进行动力相似设计,有利于提高超高速滑行艇的自航模型动力相似试验的精度和实用性,可以满足超高速滑行艇实船和自航模型的动力系统的设计需求。
