Again, as the development of electric propulsion, the design and arrangement of ship power system are more flexible.Plug-in pod propulsion
Structure, full circle swinging propulsion, hydraulic jet propulsion, and it is traditional with major axis driving be current electric propulsion several primary structures, but
There is no fundamentally change to divide water wedge structure, it is still necessary to overcome larger wave making resistance and point water resistance.Although it can pass through
Propulsion system power is improved, to reach the purpose of high headway, but is not most economical, energy-conserving and environment-protective modes eventually.
In summary, the propulsion system design of the waterpower ROV such as ship, underwater robot, it would be highly desirable to carry out revolution
Change, change it is almost unchanged over the past thousands of years divide water wedge shape forepart construction, be fundamentally greatly lowered wave making resistance and point
Water resistance, improve headway.
