The invention belongs to the technical field of supercavitation, particularly relates to a post-jet underwater vehicle and a cavitation control method, and provides the following scheme aiming at the problems that the shape and the structure of the conventional post-jet underwater vehicle are uniform and no clear improvement scheme exists on the structure for maintaining the stability of the supercavitation: the post-jet underwater vehicle comprises a column section body and a cone section body, the column section body and the cone section body are fixedly connected, and the column section body and the cone section body are provided with through air cavities. According to the rear spraying type underwater navigation body and the cavitation bubble control method, a rear engine conveys generated air flow to a first air channel, a first pressure valve on the first air channel presets a threshold value in advance, and when the air flow pressure does not reach the threshold value, the air flow is guided into an air cavity through a first air guide pipe and discharged out of micropores in a conical section body; the supercavity stability is maintained; and the micropores in the annular array are formed in the conical section body, so that air flow can be more uniformly provided for the supercavitation, and the stability of the supercavitation can be better maintained.

    本发明属于超空泡技术领域,尤其是一种后喷式水下航行体及空泡控制方法,针对目前的后喷式水下航行体形状结构统一,在对维持超空泡稳定性的结构上没有明确的改进方案,现提出以下方案,包括柱段体和锥段体,所述柱段体和锥段体之间固定连接,且柱段体和锥段体上设置有贯通的气腔室。本发明公开的一种后喷式水下航行体及空泡控制方法,后置发动机将产生的气流输送至第一气通,第一气通上的第一压力阀提前预设阈值,气流压力未达到阈值时,气流被第一导气管导入气腔室内,并从锥段体上的微孔外排,维持超空泡稳定;锥段体上设置有呈环形阵列的微孔,能够更均匀的为超空泡提供气流,更好的维持超空泡的稳定性。
