Embodiment Construction

[0092] figure 1 A rigid sail 100 is shown, arranged on a boat 10 . In a ship, only the deck 11 of the ship is shown. The rigid sail 100 is shown in side view and includes a first wing body 12 and a second wing body 13 . The first wing body 12 is connected to the deck 11 of the vessel via a mast 14 . The first wing body 12 has a first base 15 and a first head 17 , and the first base 15 has a first bottom plate 16 . Similarly, the second wing body 13 includes a second base 18 with a second base 19 and a second head 20 . The mast 14 is introduced into the first wing main body 12 through the first base 15 or the first bottom plate 16 and arranged inside the first wing main body 12 . From the first base 15 the mast 14 extends across a third of the maximum height 21 measured between the first base 15 and the first head 17 . Furthermore, the first wing body 12 and the second wing body 13 have leading edges 22 , 24 and trailing edges 23 , 25 , respectively. The second wing body ...

Abstract

In order to provide a rigid sail or aerofoil sail which has a lower overall weight, is cost-effective to manufacture and does not affect the passing under bridges, power lines or similar structures arranged over busy waters, in the case of a rigid sail (100) for vessels (10), in particular, for large ships, such as bulk carriers, tankers, car transporters or bulkers, comprising a mast (14) and a first aerofoil wing body (12) mounted on the mast (14) with a base (15) and a head (17), wherein the mast (14) is inserted through the base (15) into the first aerofoil wing body (12) and is arranged within the first aerofoil wing body (12), it is proposed that the mast (14), starting from the base (15), does not extend beyond a maximum height (21) of the first aerofoil wing body (12), in particular, less than 75% of the maximum height (21).

Description

technical field [0001] The present invention relates to a rigid sail for ships, in particular for large ships such as bulk carriers, oil tankers, car carriers or oil tankers, comprising a mast and a first wing body mounted on the mast, No. A wing main body has a base and a head, wherein the mast is inserted into the first wing main body through the base and arranged inside the first wing main body. Furthermore, the invention relates to boats with rigid sails. Background technique [0002] Rigid sails, also known as airfoil sails, are increasingly proposed as auxiliary propulsion systems, even for large ships. A rigid or airfoil sail consists of a wing body, meaning an aerodynamic structure mounted on a vessel rather than a traditional sail. Rigid sails or airfoil sails act like airplane wings, usually with a rigid or strong shell. By using rigid or airfoil sails in ships, especially large ships, additional propulsion power can be provided, which can reduce fuel consumptio...
