The invention provides a fluid structure of an underwater high-speed sailing vehicle and a model simulation method. The fluid structure comprises a cavitator, a double-cone section and a column section which are connected in sequence, the double-cone section comprises a front cone section and a rear cone section which are connected in sequence, the front cone section is connected with the cavitator, and the rear cone section is connected with the column section; the half-cone angle of the front cone section is larger than the half-cone angle of a given navigation body, and the half-cone angle of the rear cone section is smaller than the half-cone angle of the given navigation body. According to the improved double-cone-section navigation body, due to the fact that the shoulders move backwards, the situation that the shoulders exceed the cavitation range and are wetted is avoided, and the underwater navigation stability of the navigation body is improved.
本发明提供了一种水下高速航行的航行体流体结构及模型仿真方法,包括依次连接的空化器、双锥段和柱段;双锥段包括依次连接的前锥段和后锥段,前锥段与空化器连接,后锥段与柱段连接;前锥段的半锥角大于给定航行体半锥角,后锥段的半锥角小于给定航行体半锥角。本发明改进后的双锥段航行体由于肩部后移,避免了超出空泡范围而沾湿,提升了航行体的水下航行稳定性。
