Because the front propeller 30 of rotation opposite each other is contrary mutually with the blade angle of after screw 20, therefore produce in the same direction and advance current.That is, in the time that boats and ships advance, rearward produce propelling current, in the time that boats and ships retreat, forwards produce respectively propelling current when contrarotation.The propelling current that produce when advancing reclaim the rotation function of the fluid that has passed through front propeller 30 to become propulsive force, so propulsion quality is improved in after screw 20 retrograde rotations.Also identical while retreating.And, can utilize deflector 150 to change the direction that is applied to the propulsive force of hull 1 by front propeller 30 and after screw 20, change the travel direction of boats and ships.
On the other hand, front propeller 30 rearward produces propelling current in the time advancing, so be subject to suitable therewith antagonistic force.This power is delivered to the first axle drive shaft 10 by forward thrust bearing 52 and works as propulsive force.After screw 20 also rearward produces and advances current in the time advancing, so be also subject to antagonistic force, this power is also delivered to direct coupled the first axle drive shaft 10 and works as propulsive force.
In the time that boats and ships retreat, the propulsive force of front propeller 30 (antagonistic force) is delivered to the first axle drive shaft 10 by back pressure bearing 53, and the propulsive force of after screw 20 is also delivered to direct coupled the first axle drive shaft 10.As a result, in the propelling unit of the present embodiment, the propulsive force producing by the action of front propeller 30 and after screw 20 in the time that boats and ships advance and while retreating is all delivered to hull 1 by the first axle drive shaft 10.
