<p>An underwater propulsion apparatus not only compactly fixable to an oxygen cylinder carried by a diver but also enabling the diver to easily change its propulsion direction without using the self-force of the diver. The underwater propulsion apparatus (100) providing a propulsion force to the diver comprises a pair of propulsion units (110) and (120) fixed to the right and left sides of the oxygen cylinder (400) carried by the diver. Each of the propulsion units (110) and (120) comprises at least a motor, a housing storing the motor, and a screw positioned at the rear of the housing and driven by the motor. Also, the motor of each of the propulsion units (110) and (120) is connected to a motor control means controlling the rotational speed of the motor.</p> |
