The profile surface for the first sail area and the profile surface for the second sail area can each be different.

A first airfoil profile and a second airfoil profile can be formed with the profile sail device. The first airfoil can be an asymmetrical airfoil and the second airfoil can be an airfoil complementary to the first airfoil. The airfoil profile can be a normal profile, the side on which the airflow is (luv) being convex and the opposite side (lee) being curved in an S-shape.

1 shows an adjustable profile sailing device 100 with external profile surfaces 102, 104 and an internal skeleton device 106. The profile sailing device 100 is used to drive a sailing vehicle not shown here. The skeleton device 106 specifies the shape of the profile sail device 100 . The profile surfaces 102, 104 form sail surfaces of the profile sail device 100 and are stretched over the skeleton device 106. The profile sail device 100 has a first profile surface 102 and an opposite second profile surface 104 . An interior space 108 is formed between the profile surfaces 102, 104, in which the skeleton device 106 is arranged.

The profile sail device 100 has an airfoil profile with which dynamic propulsion can be generated using an airfoil effect. The airfoil profile of the profile sail device 100 can be adjusted between two end positions. Operating positions for flow onto the first profile surface 102 and operating positions for flow onto the second profile surface 104 can be set. The surface of the sail to which the flow is directed has a convex surface. The opposite sail surface has an S-shaped curved surface. The profile sail device 100 has a profile nose 110 with a nose radius and a profile trailing edge 112 with a trailing edge angle. The longest line from the leading edge 110 to the trailing edge 112, which is identical to the chord, determines the chord. The profile camber results from the greatest possible deviation of a skeleton line from the profile chord. The line that lies exactly between the profile surfaces 102, 104 in the cross section of the profile sail device 100 is referred to as the skeleton line. The profile contour of the profile sail device 100 is therefore symmetrical about the skeleton line. Another definition is: The skeleton line is the line connecting the circle centers inscribed in a profile. The profile thickness is the largest possible circle diameter on the mean line within the profile. The profile curvature largely determines the maximum propulsion and is essential for a moment coefficient.

The tread surfaces 102, 104 may be a woven cloth made from synthetic fibers. The profile surfaces 102, 104 can be formed with a laminate sail in which fibers are bonded to foils or a fabric. The profile surfaces 102, 104 can be formed with a membrane sail in which reinforcing fibers are already introduced during manufacture of the sail according to an expected load line. The profile surfaces 102, 104 can have synthetic fibers, for example made of polyamide, polyester, polyethylene naphthalate, aramid and/or carbon fibre.

The skeleton device 106 has a plurality of, here 19, adjustable frame devices, such as 114. The frame devices 114 can each be adjusted actively or passively. The frame devices 114 each have a fixed luff-side frame section and a tack-side second frame section with flexible battens. The profile sail device 100 can thus be adjusted.

The profile sailing device 100 is arranged on a mast 116 . When the profile sail device 100 is hoisted, the mast 116 extends into the interior space 108 and through openings in the frame devices 114 . There is clearance between edges of the openings and the mast. The frame assemblies 114 are limited in displacement on the mast 116 . The frame devices 114 are displaceable on the mast 116 in the direction of the mast axis. The frame assemblies 114 are pivotable about the mast 116 . The profile sail device 100 can thus be pivoted about the mast 116 . The mast 116 runs in the wing profile behind the profile nose 110, so that a smaller section of the profile sail device 100 extends between the mast 116 and the profile nose 110 and a larger section of the profile sail device 100 between the mast 116 and the profile trailing edge 112. In the present case, the mast 116 is fixed, in particular non-rotatably, to a vehicle body, such as a boat hull. Mast 116 may be keeled and passed through a deck. Alternatively, the mast 116 can stand on the deck and be supported from below on the keel.

For reasons of clarity, only one actuating cable element 210 is shown and described here, but in fact the frame device 200 has another symmetrically arranged and effective actuating pull element for adjusting the frame device 200 in an opposite direction.

The frame assembly 200 has a longitudinal axis 212 extending between a luff side 214 and a leech side 216 and a width transverse thereto. Starting from a neutral middle position, the frame device 200 can be adjusted optionally into a first end position or into a second end position. In the neutral middle position, the longitudinal axis 212 is straight. With an adjustment in the direction of the end positions, the longitudinal axis 212 is bent. 2 shows the frame device 200 in an end position.

The luff frame portion 202 is fixed with respect to adjustability of the frame assembly 200 and includes a bow member 218, a rod member 220 and two first connecting members 222, 224 for connecting the bow member 218 and the rod member 220 to each other. The arched element 218 has a clamp-like curved shape and forms a luff-side end of the frame device 200. The rod element 220 serves to absorb and/or transmit compressive forces and extends with its longitudinal axis transverse to the longitudinal axis 212. The arched element 218 and the rod element 220 form one triangular frame. The first connecting elements 222, 224 each have a triangular shape, are arranged on the curved element 218 and each have a receptacle for one end of the rod element 220.

The frame means 200 has two sleeve-shaped second connecting elements 226, 228 for connecting the luff-side frame section 202 and the tack-side frame section 204 to one another. The second connecting elements 226, 228 each have a receptacle for one end of the arched element 218 and for one end of a batten 206, 208.

The battens 206, 208 are each connected at one end to the connecting element 226, 228 and each extend starting from the luff-side frame section 202 towards the leech-side 216. The battens 206, 208 are each compressively stiff and tensile. The sail battens 206, 208 each serve as a pressure batten for absorbing and/or transmitting compressive forces and/or as a tension batten for absorbing and/or transmitting tensile forces. The battens 206, 208 are each elastically flexible.

The frame device 200 has a rod element 230 articulated to the first batten 206 and the second batten 208 . Rod element 230 is used to absorb and/or transmit compressive forces and extends with its longitudinal axis transverse to longitudinal axis 212. Rod element 220, sail battens 206, 208 and rod element 230 form a quadrangular frame with which frame device 200 is attached to a mast 232 is arranged. The frame device 200 has a tension element 234 acting between the battens 206, 208, which extends transversely to the longitudinal axis 212 in the tensioned state and serves to transmit tension forces.

For the articulated connection of the rod element 230 to the sail battens 206, 208, the frame device 200 has two third connecting elements 236, 238 with joints, such as 240, for the articulated connection of the rod element 230 to the sail battens 206, 208. The third connecting elements 236, 238 each have a joint part, such as 242, assigned to a batten 206, 208, and a joint part, such as 244, assigned to the rod element 230. figure 5 shows the rod element 230 articulated to the sail batten 208 in a longitudinal sectional view and in a cross-sectional view. The joint part 242 is firmly connected to the sail batten 208, in this case clamped. The joint part 244 is firmly connected to the rod element 230 .

The battens 206, 208 extend along the longitudinal axis 212 and, starting from the rod element 230, are at a distance from one another that decreases in the direction of the leech side 216. The ends of the battens 206, 208 on the leech side are each free and can be displaced relative to one another, in particular in the longitudinal direction of the batten. The sail battens 206, 208 are used to attach a sail and can each be connected to the sail.

The frame device 200 has first force introduction elements 246, 248 at the ends of the battens 206, 208 and second force introduction elements 250, 252 spaced apart from these. The force introduction elements 246, 250 are firmly connected to the first batten 206. The force introduction elements 248, 252 are firmly connected to the second batten 208.

The first force introduction elements 246, 248 each have an inner part for arrangement on the inside of the sail and an outer part for arrangement on the outside of the sail. The inner parts are firmly connected to the battens 206, 208. An inner part and an outer part are each screwed together. A sail can be clamped between the inner part and the outer part.

A fastening hole, such as 254, and a deflection roller, such as 256, are arranged on the inner parts of the first force introduction elements 246, 248 in each case. A deflection roller, such as 258, is arranged on the outer parts of the first force introduction elements 246, 248 in each case. The deflection rollers 256, 258 have axes of rotation parallel to one another. Two deflection rollers, such as 260, 262, are arranged on the second force introduction elements 250, 252 in each case. The deflection rollers 260, 262 have mutually perpendicular axes of rotation.

The actuating pull element 210 acts between the first force application element 246 of the first batten 206 and the second force application element 252 of the second batten 208 and is used to transmit tensile forces. The actuating pull element 210 is fastened on the inside of the sail to the fastening hole 254 of the first force introduction element 246, and guided around the deflection roller 260 of the second force introduction element 252, the deflection roller 256 of the first force introduction element 246 and the deflection roller 262 of the second force introduction element 252. A pulley is thus formed on the inside of the sail. The actuating pull element 210 is then guided on the deflection roller 256 to the outside of the sail and around the deflection roller 258 of the first force introduction element 248 . 4 shows the sail battens 206, 208 of the leech-side frame section 204 of the frame device 200 as well Force introduction elements 246, 248, 250, 252 and the actuating pull element 210 in detail.

The actuating pull element 210 is then guided in the manner of a bowstring on the second sail batten 208 to the luff side 214 . The first connecting elements 222, 224 each have two deflection rollers, such as 264, 266, with axes of rotation perpendicular to one another. The actuating pull element 210 is then guided on the deflection pulley 264 to an inside of the sail and around the deflection pulley 266 to a ship's deck.

To adjust the frame device 200 in the in 2 End position shown starting from the neutral central position, the actuating pull element 210 is subjected to a tensile force, so that the first force introduction element 246 of the first batten 206 and the second force introduction element 252 of the second batten 208 are pulled toward one another. The first batten 206 is subjected to a compressive force and the second batten 208 to a tensile force, the ends of the battens 206, 208 on the leech side are displaced relative to one another, the battens 206, 208 and the longitudinal axis 212 are positioned as in FIG 2 shown flexible curved. In the bent state, the battens 206, 208 are prestressed and serve as mechanical energy stores. When the actuating pull member 210 is released again, the frame assembly 200 resiliently returns to the neutral center position.
