Abstract

Technology Field
[0001] The present invention relates to a hybrid drag sail that can be attached to a ship to generate electricity from wind power and simultaneously function as a drag sail. Background Technology
[0002] Under global carbon emission regulations, the International Maritime Organization (IMO) requires that carbon emissions from ships worldwide be reduced by 40% compared to 2008 levels by 2030.
[0003] With plans to reduce carbon emissions by 70% compared to 2008 levels by 2050, the adoption of eco-friendly technologies in the shipbuilding industry has become a necessity rather than an option.
[0004] Accordingly, shipbuilding companies are developing LNG fuel supply systems and shaft generator motor systems (eco-friendly technology that generates electricity using the rotational force of a ship's propulsion engine shaft while it is in operation) to meet strengthened environmental regulations.
[0005] A drag sail, referred to as a new concept sail, is attracting attention as an important technology that will lead to the reduction of carbon emissions from ships due to its advantage of being easily installed by modifying a ship.
[0006] The sail according to the present invention is a new concept hybrid sail that is mounted on a ship to obtain drag thrust by utilizing wind power and simultaneously produces power with some wind power. Prior art literature
