Definitions
- the invention relates to a system for setting a free-flying kite-like windage element in a watercraft with wind propulsion.
- the invention has for its object to provide measures in such a setting system, which make it possible, a wind attack system in a practical
- the invention is based on the knowledge that even for the mountains, the windage element are guided into a position in which it can be safely and easily recovered.
- an azimuthally pivotable holder is provided, by means of which the wind-engaging element, on the one hand, can be brought into a position for seating in which it is exposed to sufficient wind action.
- a Andockabilityvorraum for releasable connection with the docking adapter of the windage element is directed in each case to the side facing away from the wind, both driven tracking means and a kind of "wind vane" may be provided.
- the Andockingvoriques is designed so that it also allows locking by automatically engaging holding means for recovering the Windangriffselements.
- the starting position is arranged offset in the horizontal and / or vertical direction relative to the location of the last cable guide in the set state of the windage element.
- the latter is usually formed by the winch or is located near the winch. In this way, the Windangriffsele- ment in the operating state can be operated independently of the starting device.
- Another advantageous development of the invention is configured in such a way that in the free-flying kite-like wind-engaging element, a traction cable which fences out into a number of tethers is connected to the vehicle. is provided, wherein a connection cable bridging the fanning point is provided, which is guided by the docking device on the wind engaging element to a - viewed from the wind engaging element - beyond the Auff kau ceremoniesspunk- tes connection point to the main part of the pull rope, and that a Sorgleine is provided which of the Andockabilityvorides emanates and whose free end is at least in the region of the connecting cable on the pull rope frictionally displaceably guided.
- the care line can preferably also be formed by a case or the like, when the wind engagement element is used on a pleasure craft.
- an additional care line is connected to the pull rope via a rope switch, which has means for designing a guide device designed as a zip-line, which is connected to the end of the care line, from its position on the pull rope when the wind-engaging element is recovered to transfer to the caregiver, while the windage element is connected via a further linen part with the rope switch.
- the rope switch has a substantially T-shaped profile, which is ⁇ -shaped embraced by the guide device. In this way, the gripping and recovery of the windage element is facilitated.
- the azimuthally rotatable docking receptacle has a device which automatically sets the active direction of the pickup to leeward, an automated recovery process can be realized, so that even with a possible malfunction of the control part or a connected, for the operation of the windage element important device automatically safe recovery of the windage element is triggered.
- the receiving device can also be self-standing to Lee by a pulley for the Sorgleine is eccentrically connected to the receiving device, so that the standing under wind pressure Windangriffselement the receiving device automatically pulls to the Lee.
- the docking receptacle and the wind engagement element are designed such that a minimal load is exerted on the system by the wind engagement element in the attached state. This is achieved, for example, when the wind engagement element is guided on the docking receptacle in its aerodynamic equilibrium point. If this is the case, then the wind-infested windage element generates exactly the lift needed to neutralize its weight. Thus, the wind engagement element "floats" on the docking receptacle, which then only has to absorb the horizontal resistance forces acting on the wind attack element, but which are relatively low, since the wind attack element is docked with its narrow front side Benefits for sizing.
- the wind attack element on a Reffein in which case the setting and / or the recovery of the so far flexible trained windage element takes place in a reefed state.
- the wind engagement element has a fixed, non-reusable central part.
- the reefing is advantageously designed when the reefing mechanism has drawstrings directed in the direction of the reefing operation, which preferably can be actuated with a winch provided inside the wind-arresting element, the reefing preferably taking place in a lateral extension of the airfoil profile.
- the wrinkles arising during reefing are advantageously taken in between regions with a fixed profile cross-section, with an identical profile cross-section being provided essentially over the entire airfoil length.
- the wind force transmitting element is designed so that it has a slight curvature across its width. This allows the windage element reffen easier, since the frictional forces of the reef ribbons are reduced in the element. Furthermore, it is advantageous in this development that the reefed wind engagement element has a lower height than a reefed wind attack element with a large curvature. However, the flight characteristics are significantly improved at a smaller height, so that the control of the element is facilitated.
- At least one inflatable element is provided in the area of the leading edge of the wing and / or between the areas of fixed wing cross-section, which also serves to assist in the descent.
- the raised position forms the upper end of a particularly telescopic crane, in which preferably hydraulic cylinders with adjacent or successive telescope segments are connected to the drive.
- the mobile crane expediently has an aerodynamically lined connection element which has a feed and a connection element for compressed air, which can be connected to the inflatable body of the wind engagement element.
- a strong blower is provided either on the crane base or in the docking receptacle of the system, which is also suitable for the suction operation.
- an opening with a relatively large cross-section which is connected in the docked state so conclusive with the docking receptacle that the windage element can be quickly aerated or vented by the fan. It can easily be seen that the setting and recovery process can be accelerated by this device.
- a refining operation with free-flying wind engagement element can be triggered by a remote control or by the output signal of at least one sensor element, wherein the venting process can also be triggered in the case of an airbag element having an inflatable element.
- An emergency procedure is preferably initiated by the rapid opening of a closure region closing off the inflatable element, in particular together with rapid retraction of the pull cable of the wind engagement element.
- the illustrated invention is particularly suitable for seagoing vessels or those with sailing areas in the area of large lakes.

- a wind engagement element 1 via a pull cable 1.1 with a force application device 2, which is provided in the bow region of a ship 4, connected to the latter.
- the traction cable 1.1 is guided to a central nacelle 1.2, from which a number of tethers 1.3 emanates, which are guided to the designed like a paraglider with kite profile windage element 1 and give this the necessary shape.

- the corresponding wind vector is through his Size and direction marked.
- variable B characterizing the gustiness
- W the time-average deviation of the wind speed from the mean value
- a coordinate system is reproduced, which is used in the following description as a reference system.
- x s is the direction of travel of the ship
- y s is the direction transverse to the direction of travel.
- the coordinate system is to think firmly connected to a point P s of the ship. This point is preferably the force application point 2 in the bow area.
- the height h s corresponds to the direction of the axis z of the conventional coordinate system. It indicates the height above the reference point P s .
- This reference point is preferably the location of the attachment of the GPS antenna of an on-board GPS device so that the coordinates of a point outside P s where another GPS device is located are obtained by subtracting the coordinates output by both devices can be generated. (If the GPS antenna onboard own GPS device is away from the reference point P s , this can be taken into account by adding a fixed coordinate difference.)
- the angle ⁇ forms the azimuth angle and the angle ⁇ the elevation angle.
- the direction of the vector V points to the nacelle 1.2 of the windage element 1.
- this is a "geographical coordinate system” since the nacelle 1.2 or the windage element 1 essentially move on the surface of a sphere.
- the azimuth angle ⁇ and elevation ⁇ thus give something like the geographical see the length and width of the position of the nacelle on the "globe" spanned by the vector V.
- the length of the "vector V is roughly the length of the hawser to 1.1, wherein the first slack should remain out of consideration.
- the nacelle 1.2 of Windangrif selements is aligned according to a, own coordinate system with the directions x k , y k and z k , wherein z k points in the direction of extension of the vector V.
- the rotation of the nacelle 1.2 of the wind arresting element 1 about the vertical axis z k is designated by the yaw angle (Yaw).
- Yaw yaw angle
- the yaw angle can be changed, inter alia, by the active activation of (described further below) brake flaps of the wind attack element 1 forming paraglider.
- a rotation about the longitudinal axis x k represents a rolling motion (roll) and is not actively controlled. From the rolling motion or the corresponding deviation of the direction of z k from V, the sag of the pull rope 1.1 can be determined by gravity, while the rotation about the transverse axis y k forms the inclination (pitch) of the wind attack element about the transverse axis and through gusts and their action on the pull rope 1.1 may be caused.
- This frame of reference forms the basis for understanding the description of the ship-kite system described below.

- An upper textile cover layer 106 forms the conclusion upwards.
- the two cover layers are held together by internal connection lines or corresponding connecting elements, such as textile ribs, which are not visible in the figure, whereby the airfoil profile formed by the two cover layers is stabilized by an internal air pressure which is established via openings on the leading edge of the kite (FIG. in the drawing on the left), which are also omitted in the drawing for reasons of clarity.
- the direction of flight is indicated by the arrow 107.
- Fig. 2 is a schematic representation of the wind propulsion system according to the invention is shown as a block diagram. The picture also serves for orientation in the following description of the individual system components.
- the 100-th reference numerals used in the overview display also form the group designation of the system parts detailed below.
- a dashed line 99 delimits those assemblies, which must be added to at least one conventional ship, so that it is additionally equipped with the wind drive according to the invention.
- the wind attack system 100 comprises the windage element and the associated control system, as far as it is located directly at this is.
- the arrangement can be arranged either in a nacelle located at the end of the towing cable from which the tethers extend, or it can also be incorporated directly into the wind tapping element.
- the control system essentially comprises an autopilot, which controls the attitude and trajectory control of the windage element.
- the wind attack system 100 is connected to the on-board system 200 via the pull cable and a winch 210 (including pull rope) and dashed communication paths with a user interface 205 which includes a control system that controls both the kite position and the engine 5 and the rudder 6 of the ship gives the necessary control commands.
- the on-board system is connected to the windage element via various communication paths, which allow both the kite position from the on-board system to be given in principle and the wind attack system to receive information relevant to the on-board system.
- a navigation system 300 Upstream of the on-board system 200 is a navigation system 300, which transmits to the on-board system the route of the ship to be observed, taking into account costs, times, speed and wind utilization and optionally the wind direction and wind strength.
- the wind information may also include a marking that characterizes the gustiness of the wind.
- information about the sea state or the resulting movement of the ship can also be obtained.
- the navigation system is supported by the navigational information finder (moving map) 310.
- wind and wave information signals are generated which control the on-board system 200 and effect a corresponding adjustment of the kite system 100.
- the on-board system 200 further generates drive signals for the engine 5 and the rudder 6.
- the navigation system 300 is operated by a route system 400 controlled, which determines the route of the ship on the underlying economic operation of the ship.
- the route system 400 is driven on the basis of predetermined data from an external station 500, which are matched with the data of a weather information system .600.
- the course data currently determined by the navigation system 300 are reported back to the external station 500 via a feedback link 301 (via radio, satellite).
- the data can also be received by other ships equipped with the system according to the invention and can be used for local updating of the weather system. In this way, current, locally caused course changes in the further external route specification can be considered as.
- the positioning of the kite system 100 takes place in such a way that both due to the weather conditions (currently prevailing winds and sea conditions) and taking into account the economic boundary conditions, which are to provide the most cost-saving possible ship operation, an optimal route specification takes place.
- An emergency system 700 provides the necessary control commands in the event of an unforeseen event which forces immediate action in the form of an emergency maneuver.
- the signaling system and communication system are summarized, which tunes the navigation with other road users.
- the signaling system includes navigation safety lighting as well as the transmission of own navigation data via radio, which inform other ships in the vicinity about the set wind attack system and the intended route or the current course.
- the communication system includes all systems which concern the further exchange of information.
- FIG. 2 The main paths of the data flow are shown in FIG. 2 as solid lines, while the remaining message paths are shown in dashed lines.
- Fig. 3 the block 100, which includes the wind attack system, and the block 200 with the on-board system of Fig. 2 are shown in more detail.
- the positioning and control of the kite 101 will be described here.
- the wind direction and wind speed information including the caliper characteristic as well as the wave information, are transferred to a buffer memory 211, in which this data for buffering is recorded. Since the wind direction and all settings of the kite refer to the apparent wind, the course information is unnecessary during processing.
- the adjustment and maneuvering of the windage element with respect to the ship does not require knowledge of the current course, since all maneuvers relate to the ship and to the effect of the apparent wind acting on the kite.
- the wind information originates when setting the kite 101 first from the weather information system 600 in Figure 2 when it comes to positioning the kite. However, as soon as its own wind measurement after the start is in function, the apparent wind is determined at the location of the windage element itself, since this is decisive for the positioning.
- the wind and sea gait data collectively form a dataset which addresses a lookup table memory 212 for the target position and maneuver type of the windage element.
- This look-up table is organized like a normal addressable memory, the output data of the buffer 211 being used as an addressable memory. Addressing the individual memory locations in which the status data of the wind engagement element belonging to the addressed data are stored.
- Such a "look-up table” connects the input and output data to one another in the manner of a "read only memory” (ROM) according to a predetermined functional relationship, and can therefore be understood as a mathematical assignment (function).
- ROM read only memory
- the corresponding blocks form only an exemplary realization and can also be replaced by any other functional elements or assemblies.
- This may be, for example, a microprocessor, in which the control software is held in a corresponding memory or else an electrical circuit, in which the functional relationship is determined in the manner of an analog computer by the participating electrical components.
- the presentation as a look-up table is chosen here for the sake of clarity, because a solution with a microprocessor, for example, is more difficult to represent only because the various to be processed one after the other
- Program steps require elaborate considerations as to which program parts are to be supplied to the microprocessor one after the other.
- control signals can be processed in parallel, although such switching elements, which cause activation of the blocks shown at certain times and the corresponding regulations are not shown.
- an incoming control signal which deviates from the previously existing signal state, triggers the processing in the subsequent blocks, which maintain the respective reached state, until a signal change forces a new processing.
- the state data thus contain, on the one hand, the desired position of the wind engagement element, ie its direction with respect to the ship and the length of the pull rope to be deployed. In addition, if necessary, they also contain information as to whether and, if so, according to which stored program the kite 101 should be maneuvered.
- the kite While the kite is static in some positions, ie fixed, it is more favorable for ship operation in certain cases when the kite is dynamically guided, ie predetermined flight figures are executed, because thereby its relative speed to the wind and consequently also its pulling power elevated.
- the current position of the kite is determined as determined by the kite 101's navigation system.
- the actual position of the kite recorded in the memory 213 relates to the ship and is preferably determined by subtraction of two GPS signals.
- this involves the GPS receiver 124 of the kite 101 within the kite system 100, which is connected to the flying kite 101.
- the position data determined in the flight position of the kite 101 are transmitted by means of a transmitter 112 to a receiver 214, which is located aboard the ship.
- Another GPS receiver 215 is also provided aboard the ship. Its output, along with the output of the receiver 214, is applied to a subtraction unit 216 which generates the differential GPS signal. Downstream in one of the subtraction unit 216
- Block 217 the difference position data in polar coordinates are converted, which relate to the distance between the winch 2 and in the position of the windage element. These are the angles ⁇ and ⁇ according to FIG. 1a and the rope length "L".
- the thus obtained Differential GPS position data are highly accurate if they are detected simultaneously and the ship's GPS receiver is installed in a location that is as little affected by ship movements as possible, or if the movements are compensated.
- GPS receiver detected position is determined at intervals. If it is insufficient in its precision, it can be supported by values determined by accelerometers 117, 119 and 120.
- the corresponding computations, which contain an integration, are executed in the assembly 123. Since within the time intervals that need to be integrated, these are only the times that elapse before the next GPS position signal, the integrators do not need to meet quality requirements that would guarantee long-term stability.
- the accelerometers are used to stabilize the maneuvers, as described below - thus receive a secondary function).
- an altimeter 129 preferably designed as an air pressure gauge, and an earth magnetic field sensor 128 are provided, whose data are also supplied to the memory for the navigation signal 124.
- altimeter 129 and terrestrial magnetic field sensor 128 data transmitted to the vessel are transmitted and recorded on the vessel in block 227.
- a difference is then formed with the data of the altimeter 233 on the ship and the geomagnetic field sensor 234 at the ship instead.
- weather data from block 600 isobars
- the position information determined in this way is fed to block 217 and, if necessary, adjusted with the GPS data. In this way, the position information of two independent systems are mutually supportive and in case of failure of a system, the required data is still available.
- the desired position of the kite read out of the memory 212 is now fed on the one hand to a comparator 218 which outputs a signal if the actual position of the wind attack system 100 present in the memory 213 agrees with the setpoint position ü read from the memory 212 ,
- a record characterizing the selected maneuver type is read from the maneuver type memory 220.
- a static flight condition can also be characterized by the fact that the kite does not perform any maneuvers but retains its flight position.
- the flight processor 116 now generates at its relevant output 125 via a corresponding drive element on the kite 101 by asymmetrical braking of the kite 101 or a corresponding aerodynamic deformation of curved flight in the predetermined sequence and duration.
- the other aerodynamic effects that are driven by the two other outputs of the flight processor 116 are the pitching of the wing and reefing, as will be described below.
- the winch 240 is also controlled for fanning to a specific desired rope length.
- a filtered through a high pass signal is additionally the flight processor, so that a swinging avoided fed 116 overlaid with a shifted phase angle to the control signal '. While 125 yawing movements can be controlled via the output 125, the hiring of the wing is set via the output 126. As is known, the ratio of flight resistance and buoyancy can be optimized by the size of a wing.
- the reefing of the kite 101 can be initiated via a further exit 127. A reef changes the buoyancy and drag and may be required for individual maneuvers.
- kite Since the kite is firmly guided on the pull rope, it is automatically stabilized by the pulling action of the rope in its buoyancy center with respect to its rolling and tilting movements. However, in order to exclude oscillation in this case as well, a position signal from a roller sender 119 and an inclinometer 120 are respectively transmitted via speak speaking inverting high pass filters 121 and 122 to the flight processor, so that jerky changes in position of the windage element 101 are avoided and compensated.
- the selected maneuver type is read which causes the kite to execute a predetermined cyclic flight program. If this type of maneuver is transmitted, the control is done automatically by the autopilot of the windage element and the unit 200 does not need to respond unless the kite leaves its target position due to unforeseen events.
- the target position of the windage element 101 does not coincide with its predetermined position, it may be that the default position read out of the memory 212 has changed - as is the case when the kite is set - or is it the kite in the kite During maneuvering, the output disappears from the output of the comparator 218, and the maneuver type of the memory 220 activated via the switching element 219 ends. At the output of the memory for the maneuver type 220 (left part), the signal "zero" appears, which is interpreted by the autopilot of the wind attack system 100 to the effect that the last stored maneuver is no longer executed.
- the actual position of the kite which is read out of the memory 213 and determined via GPS, is compared with the desired position from the memory 212 by means of a position correction unit 221 and a maneuver is determined, which leads the kite into the desired position.
- the correction unit 221 is again designed as a look-up table, wherein the desired position and the actual position (again relative to the ship) are combined to form a common addressing signal and the identification of a corresponding correction maneuver of the wind engagement element is read from the actual position A into the desired position B. It should be noted that, depending on the start and end point (and also, if necessary, depending on the wind and wave conditions), different maneuvers must be selected to maneuver the kite. With the specified measures but any dragon maneuvers can be selected and executed.
- this data may be "looped" from the memory 211 through the look-up table memories 212 and 221 so that they are still present in the specific maneuver selection record and an appropriate maneuver is selected can.
- this is not about the compensation of individual events, but about general adjustment guidelines, which may include, for example, that when the sea is high, the kite is flown relatively so that the forces acting on the vessel by the wave direction can be compensated as possible.
- general adjustment guidelines which may include, for example, that when the sea is high, the kite is flown relatively so that the forces acting on the vessel by the wave direction can be compensated as possible.
- an output signal of the sea clipping block 231 is directly supplied to the block 211 to add information which participates in the selection of the corresponding kite position and maneuvering in the sense described above.
- Another function of this connection is to select parts of flight maneuvers to counteract the accelerations due to the sea. This includes maneuvers with cyclic trajectories where different tractive forces act on the pull rope at different times, are flown so that these forces occur out of phase to the accelerations, which are caused by the sea state. In this way the ship movements are reduced overall. This compensation or reduction of ship movements by different tractive forces, which are caused by the maneuvering, do not disturb the other applied methods for the sea state compensation. The reason for this is that from the beginning reduced ship movements require less effort to reduce their impact on the hang gliding trajectory. Because of the compensation of the individual ship movements, reference is made to the description of block 231 below.
- the right-hand part of the memory 220 is addressed via a switching element 222 with the data set read out from the correction unit 221, the switching element 222 being activated by the output signal of the comparator by means of an inverter 223, if the switching element 219 is not activated, ie and actual position are unequal.
- a multi-directional dynamic pressure gauge 111 provided on the kite on the one hand forms an anemometer and, on the other hand, transmits to the component measured in the direction of flight the condition of too small a flow of the kite through a corresponding signal which, together with the generation of a position change maneuver, also drives the winch control 240
- the kite is accelerated at the position change, so that the ' flow is raised again. (It can be seen that the winch is also affected by "wanted" position changes due to wind and wel- can be driven via the right part of the memory 220b, so that, for example, a change, the height of the windage element can be brought about.)
- the wind gauge in different directions directed Pitot tubes with pressure cans, which are evaluated separately. From the pressure values of the three orthogonal pressure cans with the highest pressure values, the direction and speed of the wind with respect to the orientation of the wind gauge 111 can be determined. If the output signal of the magnetic field sensor 128, which contains a bridge circuit of magnetically sensitive resistors and thus makes it possible to determine the direction of the field lines of the earth's magnetic field, is taken into account, then the direction of the wind can be referred to the north direction and can thus be referred to as the direction of the apparent wind in Windabzugselement be transferred to the vessel. If necessary, the correction from magnetic north to geographic north takes place there.
- An arrow directed to the block 211 indicates that the normal navigation of the kite is disabled. Via an OR gate 224, which is connected upstream of the inverter 223, the rest of the normal maneuvering control is also suppressed. (This also applies accordingly to the blocks 228, 229, 230 and 232 to be described below, which trigger further special functions.) The associated signal connections have been omitted there for reasons of clarity.)
- the emergency maneuver "emergency release” is initiated by selecting and starting the associated maneuver type via the right-hand part of the maneuvering type memory 220b, which contains the respective programming.
- This maneuver becomes necessary when the ship's wind-attacking element poses a great danger due to unfavorable circumstances or an accident (eg due to a collision with an obstacle). In this maneuver, the windage element is completely separated from the ship.
- the corresponding maneuvers are initiated by selecting and starting the relevant maneuver type via the right-hand part of the maneuver type memory 220b which contains the respective programming.
- the acceleration component directed in the direction of the traction cable is determined via a suitably oriented acceleration sensor and, after integration, a signal is generated which describes the ship movements in the direction of the traction cable.
- This signal is fed to the on-board GPS receiver which provides a position signal corrected for the position of the winch control 240 if the receiver or antenna is not itself mounted in this position. If this GPS position signal were evaluated and used for guidance of the kite 101 directly in conjunction with the kite system 100 GPS position signal received via the receiver 214, it would follow in its control the sway of the winch.
- the accelerometer's integrated signal is additionally supplied to the GPS receiver 215 in block 231 to be subtracted (as a disturbance) from the signal to block 216 for processing is supplied, so that there the position signal of a "calm platform" is processed.
- the kite flies 101 maneuvers, which are characterized by sea clutter. are exempted.
- the swell-acting sea-cable portions of the flying object become noticeable, whereas proportions directed transversely thereto contribute only to a change in the angles ⁇ and ⁇ of the flight vector which disappears just in the case of a long towing rope and are therefore negligible.
- control commands can be transmitted directly to the autopilot unit and the winch control 240 in the left part 220a of the manual command maneuver memory, suppressing the rest of the signal output from this memory.
- These are the functions "Left”, “Right”, “Straight”, “Reffen”, “Recover”, “Hunt (+)”, “Hunt (-)”, “Winch (+)” and “Winch (-) ". All commands can be modulated in their intensity.
- a "predictive maneuvering" takes place in such a way that fictitious wind and course data are entered into the system for calculating the current position of the wind attack element and the configuration then being displayed for information. From this, the ship's command can then estimate the predictable behavior of the system and adjust the navigation accordingly.
- This multiple processing of the data in the manner of contingent foresight is shown in FIG. 3 by multiple angles at the corners of different memory elements, which is intended to indicate that the contents of these memories are evaluated multiple times independently of the current process control.
- additional memory means and comparator means are provided which allow a storage of signals associated with preceding times with signals appearing later in time in such a way that temporally successive maneuvering states are comparable on the basis of different - also more fictitious - input data.
- a telescopically extendable crane 180 which can be pushed out, for example, by a hydraulic cylinder (not shown), has at its end a receiving device 181 for docking, which has a recess profile on its inside 182 which adjoins the outer profile of the wind engaging element 101 in the area of its Front edge is adjusted.
- the side facing away from the windage element of the receiving device 181 is designed aerodynamic, as it points to dock in docking. Also, it should not disturb the flow of the windage element 101.
- a care line 183 is guided, which serves to attract the wind attack element to the mast when it is overtaken in the mountains by means of the winch to the height of the extended crane 180.
- This care 183 is with its free end with a - shown in detail below guide device 184, with which it "rides” on the pull rope 1.1 and then on the branching off of the pod 102 Bergeleine 1.11, near the winch 2 on the pull rope put on and then fetched until it assumes the position shown in Fig. 4.
- the Consvorrich- device 181 is rotatably mounted on the upper end of the crane 180.
- the receiving device has a guide or deflection roller 185 for the care line 183, which is situated eccentrically in the direction of lee from the azimuthal axis of rotation of the receiving device.
- the receiving device 181 is automatically rotated by the train of the Sorgleine 183 to Lee for receiving the windage element 101.
- the receiving device 181 is provided on the outside with a wind vane, so that it points automatically by the wind pressure in the direction of the wind engaging element. This is particularly advantageous when Bergen.
- a filling tube 186 which is provided on the receiving side of the receiving device 181, gets into a valve opening 187, which with. an inflatable bead 188 (shown in phantom) is in the wing leading edge in conjunction.
- the bead 188 serves to meet and stiffen the wind attack element when setting when it ventilates when setting is before the windbreaker leaves the launch crane.
- the filling tube merely needs to open a valve to let out the stiffening medium (preferably compressed air).
- the mechanism is here preferably simulated that of a floating body of a conventional dinghy.
- the crane 180 is designed to be substantially hollow.
- a blower is provided, which can also work in the suction mode.
- an air duct with a large cross section is formed, which exits on the inner side 182.
- the windage element 101 has an opening formed in accordance with the outlet opening of the air channel, so that the docked wind engagement element can be aerated or vented (by suction) by commissioning the fan. This allows accelerated setting and recovery.
- the crane and the panels are rounded outwards and formed without protruding edges, corners and other protruding parts.
- a Seilweiche 189 In the reproduced in Fig. 4a detail of the docking device of FIG. 4 in perspective view a Seilweiche 189 can be seen, which ensures that the guide device 184, which is connected to the end of the Sorgleine 183 from its position on the tow rope 1.1 during recovery of the wind-engaging element 101 on the Bergeleine 1.11 device when the Sorgleine is fetched.
- the switch 189 preferably has a T-shaped profile, which is mounted following the pull cable 1.1 and continues in the width of its transverse leg according to the thickness of the pull rope or even exceeds this width.
- the guide device 184 surrounds the cable 1.1 ⁇ -shaped, and guide elements 190 thus engage behind the cable (comparable to a guide for curtains on a T-rail), the guide device safely passes from the cable part 1.1 to the cable part 1.11, although the path of the main traction is transferred to the rope part 1.12.
- the mountain line 1.11 ends in a device which at least partially surrounds the traction cable 1.1.
- the device is designed in such a way that it fixes the end of the cover 1.11 at a defined position of the pull cable 1.1. If the wind engagement element 101 is to be recovered, then the guide device 184 of the care line 183 rides up on the pull rope 1.1 and hits the device which fixes the slip line 1.11 on the pull rope 1.1. In this case, a coupling process is triggered, so that the guide device 184 and the device for fixing the Bergeleine 1.11 together positively or positively connect with each other. At the same time, the fixation of the rescue rope 1.11 on the traction cable 1.1 is released by the coupling process, so that now the trailing rope 1.11 is connected to the care line 183, but there is no longer any connection to the traction rope 1.1.
