The invention relates to a method for improving the motion stability of a supercavitation navigation body, which comprises the following steps of: 1, determining the shape and the quality of the supercavitation navigation body, and performing a navigation simulation experiment to determine the initial position of the buoyancy center of the supercavitation navigation body; 2, the mass-buoyancy ratio is defined as the ratio of the length from the mass center of the navigation body to the top end of the head to the length from the buoyancy center to the top end of the head, and the mass center position interval is determined according to the mass-buoyancy ratio CL larger than 0.8 and smaller than or equal to 1; and 3, according to the shape and the quality of the preset supercavitation navigation body, the mass center position of the navigation body is located in the mass center position interval in the step 2, and the supercavitation navigation body with better stability is prepared. The invention provides the concept of mass-buoyancy ratio, and finds a method for improving the stable navigation of the navigation body. Experiments prove that the motion stability of the supercavitation navigation body can be obviously improved by adopting the mode provided by the invention.
本发明涉及一种提高超空泡航行体运动稳定性的方法，包括以下步骤：步骤1、确定超空泡航行体的形状和质量，进行航行模拟仿真实验确定超空泡航行体的浮心初始位置；步骤2、定义质浮比为指航行体质心到头部顶端长度与浮心到头部顶端长度的比值，根据质浮比0.8＜CL≤1确定质心位置区间；步骤3、按照预设超空泡航行体的形状和质量，并使得航行体的质心位置位于步骤2的质心位置区间内，制备得到稳定性更好的超空泡航行体。本发明提出质浮比的概念，找到了提高航行体稳定航行的方法。通过实验证明，采用本发明的方式可以明显提高超空泡航行体运动稳定性。
