Good improvement

Use of such axial flow pump, the mechanical energy can be more efficiently used for prepeling the submarine forward.  However, it the concept of centrifugal pump can be applied in the design, more driving force may be generated with slower rotational speed of the impellers.  Therefore, the noise level can be further reduced.
