The invention provides a combined type cavitator which comprises a cone part and a truncated-cone part. The cone part is arranged on the front section and the truncated-cone part is arranged on the rear section. The upper bottom face with the small diameter of the truncated-cone part is connected with the bottom face of the cone part. The diameter of the upper bottom face of the truncated-cone part is smaller than the diameter of the bottom face of the cone part. A pin hole is formed in the rear end of the truncated-cone part and used for allowing the combined type cavitator to be installed on a head of a navigation body. Due to the fact that the combined type cavitator is installed in the center of the head of the underwater navigation body, super-cavitation flow can be achieved at the low navigation speed or the large background pressure, and the problems that resistance is too large and the navigation speed is low when the navigation body navigates underwater are effectively solved.
