A utility model titled "Marine Propulsion Unit" has been registered in Russia, aimed at reducing the dimensions of ship propulsion drives without loss of power. The development relates to shipbuilding and is intended for denser placement of propulsion systems on board.
The design includes a housing with an upper cylindrical compartment, a rudder, and a gondola, inside which drive electric motors are arranged vertically.
Power is supplied to the motors through a slip ring unit, and rotation is transmitted through cylindrical and bevel gear trains to two output shafts with propellers. This configuration preserves power while making it possible to reduce the diameter of the upper compartment.
The key difference is the vertical arrangement of an even number of high-speed electric motors. This reduces the dimensions of the assembly compared with traditional horizontal layouts, which simplifies integration of the unit into the ship's hull. The solution will increase layout flexibility and the efficiency of placing power equipment.
