PROPELLER PROPULSION APPARATUS FOR SHIP - A simplified explanation of the abstract
This abstract first appeared for US patent application 18373990 titled 'PROPELLER PROPULSION APPARATUS FOR SHIP
Simplified Explanation
The propeller propulsion apparatus for a ship described in the abstract includes two propellers, each driven by an electric motor, with a control unit optimizing power consumption based on stored data.
- The apparatus consists of a first propeller and a second propeller, both driven by separate electric motors.
- The second propeller rotates in the opposite direction to the first propeller, providing balanced propulsion.
- A control unit manages the power consumption of the electric motors based on stored data of optimal rotational frequencies at different vessel speeds.
- The memory unit stores combinations of rotational frequencies for the propellers to ensure the total power consumption is at an optimum value during ship operation.
Potential Applications
This technology could be applied in various marine vessels, such as cargo ships, cruise ships, and naval vessels, to improve propulsion efficiency and reduce fuel consumption.
Problems Solved
1. Imbalanced propulsion: By having two propellers rotating in opposite directions, the apparatus solves the issue of imbalanced propulsion, leading to smoother sailing. 2. Suboptimal power consumption: The control unit ensures that the power consumption of the electric motors is optimized at different vessel speeds, reducing overall energy waste.
Benefits
1. Increased efficiency: By optimizing power consumption, the apparatus improves the overall efficiency of the ship's propulsion system. 2. Fuel savings: Reduced power consumption leads to lower fuel usage, resulting in cost savings and environmental benefits.
Potential Commercial Applications
