On the other hand, the submersible is equipped with a water jet device to run while diving underwater or to run on the surface.

In addition, the water jet of the conventional submersible has a problem that the risk of safety accidents such as damage to the wings and overheating of the engine is very high due to the phenomenon of foreign substances in the water jammed by foreign substances existing in the water such as seaweeds on the rotating shaft of the blade rotated by the motor. .

In addition, the water jet of the conventional submersible has a problem in that the underwater driving of the submersible is unstable due to the unstable operation of the wings as well as the lowering of the output due to the impeding the flow of water due to foreign substances caught in the rotating shaft.

In addition, since the water jet of the conventional submersible rotates the wing to suck water and inject water, the flow of water that generates the propulsive force is formed as a vortex, so that the propulsion efficiency is lowered, and it is difficult to accurately change the direction.
