PCT No. PCT/NO97/00337 Sec. 371 Date Aug. 11, 1999 Sec. 102(e) Date Aug. 11, 1999 PCT Filed Dec. 15, 1997 PCT Pub. No. WO98/26982 PCT Pub. Date Jun. 25, 1998A wing profile sail is in the form of a sailcloth which defines an airfoil-shaped space, which is filled with air through openings or one-way closing mechanisms. At the sail's luff (1) there is provided a bag/lung-shaped body which can be filled with air and which is extendable in the height direction and which in an extended state forms an upwardly tapering conical, cylindrical body (11). The sail's outer cloth (2, 3) extends from this body (11) and is transferred on each side from this body (11) and is attached at a distance from the after leech (7), the sail's after part (7) being composed of one sailcloth surface. From the outer sailcloth's (2, 3) attachment area, in the inner spaces of the sail there is provided an intermediate sailcloth, which at least covers the area of the openings for air supply. The outer sailcloths (2, 3) are connected in the sail's bottom area in order to form the inner spaces in such a manner that the outer sailcloths are movable in relation to each other. |
