The invention relates to a supercavitation navigation body drag reduction and range extension method. The method comprises the following steps that 1, the centroid position is determined according to the preset shape of a supercavitation navigation body; 2, the centroid position is displaced towards the head end of the navigation body by 4%-6% L, L is the length of the supercavitation navigation body, and a centroid position interval is obtained; 3, according to the shape 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 capable of reducing resistance and increasing the range is prepared. According to the method, the shape and the mass center position of the supercavitation navigation body are optimally designed, the drag reduction and range extension effects of the supercavitation navigation body can be obviously improved, and the navigational speed and the navigational range are greatly improved.
本发明涉及一种超空泡航行体减阻增程方法,包括以下步骤:步骤1、根据预设超空泡航行体的形状确定形心位置;步骤2、将形心位置向航行体头端位移4%‑6%L,L为超空泡航行体的长度,得到质心位置区间;步骤3、按照预设超空泡航行体的形状,并使得航行体的质心位置位于步骤2的质心位置区间内,制备得到能够减阻增程的超空泡航行体。本发明通过对超空泡航行体的形状和质心位置进行优化设计,可以明显提高超空泡航行体的减阻增程效果,大幅度提高航速航程。
