Patent application<br />
The solution pr<strong>op</strong>osed refers to the active steering system<br />
with transverse tunnel for ships, boats and submersible<br />
vehicles characterized by direct electric drive pr<strong>op</strong>eller,<br />
using induction motors and induced toroidal disc. The<br />
purpose of the new drives steering is direct drive of<br />
contrarotating pr<strong>op</strong>ellers (eliminating mechanical<br />
transmission) rated rotation speed. The technical problem<br />
solved by the new system is to reduce extra weight and<br />
gauge active steering, increasing overall efficiency, reducing<br />
additional maintenance costs, since power is directly<br />
transmitted from the engine to the pr<strong>op</strong>eller without<br />
mechanical transmission. Advantages gained are obvious:<br />
transmit motion between toroidal inductor and induced<br />
whole channel - pr<strong>op</strong>eller is made directly to the nominal<br />
rotation speed; to eliminate mechanical transmission<br />
between the engine and pr<strong>op</strong>eller that increases the gauge,<br />
weight and reduces plant efficiency; plant maintenance is<br />
easy and does not cost much;significantly increase system<br />
reliability.<br />
