ABSTRACT:
A submersible is provided for exploration of the sea or other purposes. The submersible includes a hull made up of three outer shell sections. A first outer shell section has one end opening through which a second outer shell section is inserted into the first outer shell section for horizontal movement. A third outer shell section is inserted into the second outer shell section through one end opening thereof for horizontal movement. Packings are applied between the first and second outer shell sections and between the second and third outer shell sections, respectively. One or both of the second and third outer shell sections are moved outwardly and inwardly by actuators so that the net displacement of the submersible is increased and decreased. By moving the third outer shell section, the center of gravity of the submersible may be transferred so as to be positioned beneath the center of buoyancy. Each propeller for underwater cruise includes a cylinder into which high pressurized fluid is fed, a piston reciprocally moved by the force of high pressurized fluid, and drivers for propelling water in response to reciprocal movement of the piston.
