Abstract

Contents of this invention are kites for periodic and continuous power generation, as a much cheaper alternative to wind turbines. The kite hangs on a rope that is wound on a reel. If a wind force acts on the kite, the rope unwinds and turns the reel. On the axis mechanical equipment such as pumps, mills or an electric generator are coupled. The kite climbs to the end of the rope, then its wind-effective area is reduced by short-term strengthening of the rope force, z. B. by buckling a strut or loosening the scale, and it is retrieved low energy by winding the rope. Below, the rope power is reduced, the dragon is restituted, rises and generates energy again. More ropes can fix it, a helium filling hold it up. In other versions, the kite goes up and down on a lead rope held by a lifter kite or lifter balloon or pole, and can generate energy in both phases.

Description

State of the art / task

The in the foreseeable future exhaustive supplies of crude oil, natural gas and coal, including uranium, are increasingly forcing people, alternative, best inexhaustible To develop energy sources. The especially the sun, directly used by solar stoves, solar panels, Photovoltaic cells or over Secondary products such as hydro, waves, tides, parabolic mirror power plants, wind, Ascending power plants, etc. The most common form of use of the wind to generate energy are wind turbines, on Towers mounted swiveling propeller with coupled power generator.

It are suggestions in the literature, on several km long ropes missile in the upper troposphere to position where permanently strong winds blow, the jet streams. In such dragon-like missiles are Turbines or wind turbines built in, which generate electricity with a high voltage cable is directed to the ground / 1 /. The feasibility of such concepts is for several reasons Questionable: Rope / cable weight, endangerment of air traffic, costs ...

at wind turbines is the area of the wings that is exposed to the wind in terms of driving power compared to the claimed one Area, the rotor surface, small. As the wind increases with the distance to the ground and he himself steady, you build the towers as high as possible, You need to with high technical effort to catch the considerable wind pressure, which makes the equipment very expensive and widely visible. Still stay they are in the range of relatively low wind speed. In the literature Lately solutions are also appearing where dragons continue to provide useful energy to be generated: After starting work, go to formulation of this invention, an American application was published / 2 /.

she describes a solution with kite (and parachute). Claimed in the main claim is that the kite in energy mode at high angle to the wind is positioned and at a low angle in the return mode. By rope, cable, Chain or similar The kite is connected to a ground station where electrical Energy is generated. (By unwinding / winding on a reel). their Claim 2 mentioned the direct use of mechanical energy from the reel. claim 3 beats a second rope for control. The text will be remotely controllable Mechanisms on the dragon to change specified the angle of attack for reversing between climb and sink phase. The Dragons are as resistance bodies educated.

The remotely controllable electromechanics with accumulator means technical Effort (costs), regular recharge of the supply battery, susceptibility and danger from its weight when the kite falls down. The 2. Rope means a 2nd ground station or significantly more effort in the first. In case of unintentional but hardly completely rollover of the dragon, both ropes and the whole mechanism are involved blocked.

A similar Principle follows a group in Delft / 3 /, but as in / 1 / in the high air layers with one above the other layered kite designed for megawatts.

The solution to be described here provides advantageous alternatives to these approaches and to the earthbound ones Wind turbines.

• a. deutlich bessere Nutzung der Windverhältnisse, d.h. Betrieb in höheren, windstärkeren, turbulenzärmeren Luftschichten, auch für größeren Windbereich auslegbar (die Energieausbeute wächst mit der 3. Potenz der Windgeschwindigkeit),
• b. in der Größe weitgehend frei skalierbar, d.h. auch sehr groß, stets strömungsmechanisch optimal realisierbar, deshalb geringere Notwendigkeit von Parks,
• c. auch optisch akzeptabler, ohne Gefahr für Vögel,

Advantages over wind turbines:

• a. significantly better use of wind conditions, ie operation in higher, windier, turbulence-poorer air layers, even for larger wind range interpretable (the energy yield increases with the 3rd power of the wind speed),
• b. largely freely scalable in size, ie also very large, always optimally achievable in terms of fluid mechanics, therefore less need for parks,
• c. also optically more acceptable, without danger for birds,

Regarding the other dragon projects also applies d. to f. In particular intended the effort for control electronics be significantly reduced and it should be energy efficient shorter Breaks in energy production and lower return performance can be increased.

inventive idea

One Dragon hangs on at least one rope. The rope is wound on a spool / reel. acts a windpower on the kite, the rope unwinds and turns the reel. On its axis are mechanical devices such as pumps, Mills, saws, threshers etc. coupled, or even an electric generator. The Dragon rises to the end of the rope, then it becomes as low-energy and fast as possible retrieved. This happens periodically.

• I. durch Verringerung des Anstellwinkels, d.h. Flachstellen des Drachens, wie in /2 und 3/ beschrieben; oder wirksamer
• II. Lösen eines Waage-Seiles
• III durch seitliches Kippen;
• IV. durch Verkleinern der Drachenfläche, z.B. Knicken der Drachenstreben, Zusammenziehen der Drachenfläche, Lösen der Bespannung;
• V. durch Umstellen von Aufrieb auf Abtrieb durch Umkehrung der Flugeigenschaften, z.B. auf den Kopf stellen des Drachens

The kite can develop its power as a resistance or buoyancy body. As a rule, more or less both forces act. To get up, he is trained so that he exerts the greatest possible force on the working rope. When operated as a resistance body, it creates the strongest pull by being perpendicular to the wind, ie angle of attack 90 °. Designed as a buoyant body, such as a wing (mats, parafoil, sled, flowform), it should stand so steeply in the wind for maximum buoyancy that the current just does not break off. The low-energy, fast retrieval is accomplished by changing the flight characteristics of the kite, in such a way that the wind power is as low as possible. The latter can be done in several ways, eg

• I. by reducing the angle of attack, ie flattening of the kite, as described in / 2 and 3 /; or more effective
• II. Release a balance rope
• III by lateral tilting;
• IV. By reducing the dragon's surface, eg kinking of the dragon's struts, contraction of the dragon's surface, loosening the clothing;
• V. by shifting from Aufrieb to downforce by reversing the flight characteristics, eg upside down the dragon

• a. durch einen am Drachen angebauten ferngesteuerten Mechanismus, oder
• b. durch ein oder mehrere Hilfsseile zum Drachen, die jeweils den Anstellwinkel verändern; oder aber vorteilhafter
• c. durch Konstruktion des Drachen auf eine Weise, dass er bei Windlast über einem Schwellbetrag automatisch in den Sinkzustand fällt, also einer der Zustände I bis V eintritt. Das soll zum einen geschehen als Sicherheitsreaktion bei zu starkem Wind. Oder im Regelfalle zum Zurückholen, indem die Haspel ein Stück schnell aufgewickelt oder das Seil anderweitig schnell verkürzt, also ein Ruck erzeugt wird und damit über das Seil und den Wind große Kräfte auf den Drachen wirken, die den Sinkzustand auslösen. Oder
• d. indem der Drachen als Fähre auf dem Halteseil eines anderen am Himmel geparkten Lifter-Drachens oder Lifter-Ballons rauf und runter läuft, auf jenem Seil Anschläge angebracht sind, an denen die Eigenschaften der Drachenfähre so verändert werden, wie in I bis V beschrieben.

The change of these dragon properties is triggered either as described in / 2 / and / 3 /:

• a. by a dragon-mounted remote-controlled mechanism, or
• b. by one or more auxiliary ropes to the kite, each changing the angle of attack; or more advantageous
• c. by constructing the kite in such a way that it automatically falls into the sinking state during wind load above a threshold amount, ie one of the states I to V occurs. That should happen on the one hand as a security reaction in case of excessive wind. Or usually to retrieve by the reel wound up a bit quickly or otherwise shortened the rope quickly, so a jerk is generated and thus act on the rope and the wind large forces on the dragon, which trigger the sinking. Or
• d. As the kite travels up and down the tether of another lifter kite or lifter balloon parked in the sky, there are stops on that rope where the characteristics of the kite ferry are altered as described in I through V.

in the Descent is the kite rope active with the help of a motor or a spirally stretched spring wound on the reel.

In the lower reversal position becomes c in our solution. the reel for a moment released, it no longer affects wind or rope power, the kite is due to built-in restoring forces (springs) put back in the climbing state. At d. pulls the dead weight and possibly the reel over the kite rope the kite in the lower stop and the acting ones personnel bring the dragon into the climbing form.

at all these solutions The kite on the rope can move freely in all directions with the wind or he can use tethers that absorb the lateral drag forces are kept essentially stationary and only largely vertical working rope converts the buoyancy forces into useful energy.

• e. Das Halteseil wird als unendliche Schlaufe (Doppelseil) zwischen der unteren Haspel, die nunmehr als einfache Rolle fungiert, und einer Rolle oben am Lifterdrachen/-Ballon aufgespannt. Die Fähre ist an einer Seite dieses Doppelseiles befestigt, wird durch den Wind nach oben getrieben, am oberen Anschlag so verändert, dass der Auftrieb in einen Abtrieb umschlägt. Das drückt den Drachen mit Windkraft (neben dem Eigengewicht) nach unten. Am unteren Anschlag wird er wieder auf Auftrieb geschaltet. Er steigt wieder etc. Diese Anordnung erzeugt beim Steigen und Sinken Energie also fast kontinuierlich! Der Lifter kann frei floaten oder wieder mit Halteseilen ortsfest gehalten werden.

A solution that uses wind energy more effectively

• e. The tether is tensioned as an infinite loop (double rope) between the lower reel, which now acts as a simple reel, and a reel at the top of the lifter kite / balloon. The ferry is attached to one side of this double rope, is driven by the wind up, changed at the top stop so that the buoyancy turns into an output. This pushes the kite down with wind power (next to its own weight). At the bottom stop it is switched back to buoyancy. It rises again, etc. This arrangement produces energy almost continuously during the ascent and descent! The lifter can float freely or be held stationary again with tethers.

• f. Die Funktion des Lifterdrachens übernimmt ein Mast, eine lange Stange, die mit Seilen fest am Boden verspannt ist. Die Fähre läuft an der Stange rauf und runter und wird an oberen und unteren Anschlag wie bei e. umgestellt.

Another possibility of a fixed installation offers

• f. The lifter kite function is carried out by a mast, a long pole fixed to the ground with ropes. The ferry runs up and down the pole and gets to top and bottom stop as at e. changed.

• g. Der Drachen wird am oberen und unteren Umkehrpunkt nicht gestoppt und mechanisch verändert, sondern er läuft über die obere und untere Rolle weiter, wird dabei jeweils auf den Kopf gestellt, so dass er rauf und runter ohne Unterbrechung Energie erzeugt.

The solution is even simpler and more efficient

• G. The kite is not stopped at the upper and lower reversal point and mechanically changed, but he continues on the upper and lower roll, ge is in each case on the head ge so that it generates energy up and down without interruption.

The You will not build fixtures with masts as high as one can extend kite ropes, but has the advantage of robustness and complete Stationary unit. They would be slightly higher to build as towers for wind turbines and significantly cheaper as these with all other advantages mentioned in the task.

Some The plants deliver the energy with short interruptions, what in many cases (for pumping, grinding, threshing) completely is acceptable.

• A. durch mehrere Drachen, die zeitversetzt aufsteigen;
• B. durch Speicherung als elektrische Energie, etwa in Akkumulatoren
• C. durch Speicherung der mechanischen Energie, z.B.
• C1. in einem Schwungrad;
• C2. im in ein hoch liegendes Becken gepumpten Wasser, das beim späteren Herabfließen z.B. ein Mühlrad oder eine Turbine treibt (und schließlich Felder bewässert);
• C3. in anderen angehobenen Körpern, die dann ihre Energie über eine Haspel wieder als Rotationsenergie abgeben;
• C4. über ein per Pumpe unter Druck gesetztes Gas;
• C5. als Wärmeenergie, indem bei der Rotation Reibungswärme erzeugt wird, die etwa in Öl oder festen Körpern zwischengespeichert wird , dann z.B. auch in Wärmekraftmaschinen, etwa einem Stirlingmotor, umgesetzt und natürlich auch direkt zum Kochen oder Heizen verwendet werden kann;
• C6. durch Elektrolyse erzeugten Wasserstoff, der dann in Brennstoffzellen wieder elektrische Energie erzeugt und durch andere Energiespeicherformen.

If a uniform energy supply is desired, this can be done in the above way. and following ways happen:

• A. by several dragons ascending with a time delay;
• B. by storage as electrical energy, such as in accumulators
• C. by storing the mechanical energy, eg
• C1. in a flywheel;
• C2. in the water pumped into a high lying basin, which drives a mill wheel or a turbine (and finally irrigates fields) during the later downflow;
• C3. in other raised bodies, which then release their energy via a reel as rotational energy;
• C4. via a pressurized gas pump;
• C5. as heat energy by generating frictional heat in the rotation, which is temporarily stored in oil or solid bodies, then, for example, in heat engines, such as a Stirling engine, implemented and of course can be used directly for cooking or heating;
• C6. Hydrogen produced by electrolysis, which then generates electrical energy in fuel cells and other energy storage forms.

In order to keep the working or lifter kite in windless heights on the ground at wind-high altitude or to transport it there, there are the following possibilities:
The kite is constructed as a cave body, partially filled with helium or warm air, or the kite is filled with correspondingly filled hollow bodies (balloons). A second is to "pump" the balloon in the usual dragon technique, ie to pull it up at a suitable angle of attack periodically with the reel, let it drift with the wind, pull it up again, etc.

The Adaptation of the kite to the prevailing wind speed by built-in elastic elements, such as in the balance parts, or by presetting e.g. the angle of attack. The systems work best on open ground, on mountain tops, well over too Water areas, e.g. mounted on ships.

With regard to the pitches, there are no basic limits. Of course, with the rope length also its weight increases, which, if it came in the order of the dragon's weight, would let the kite start only with larger wind forces or with more helium filling. As a rope material is recommended for other kites, for fishing and sailboats usual:
Polyester, stretched polyethylene, carbon fibers, for large plants also metal (steel).

Device for switching the kite between climb and descent, in this case realized by a magnetic coupling. It releases at a certain train on the balance 23 , here in the state of just loosing. The two parts of the coupling separate, the lower part of the kite is released, he hangs only on top of the center strut 27 and the kite loses wind power, it sinks. In this phase, the rope is wound up. Between the balance point 33 and the right magnet 30b sits a plastic tube, into which a rubber rope 32 low force to the left magnet 30a is guided. Through the cable during active winding the rubber is stretched. Once the rope has been wound up to the desired point, the return motor switches off, the rope slackens, the rubber band pulls the magnetic coupling back together, the kite is able to climb again, the generator 6 is switched on, the kite rises again and generates energy. The strong forces on the kites, which trigger the magnetic coupling, arise at a large difference between wind speed and kite speed. They can be caused either by 1. strong wind or 2. the stop at the end of the rope or 3. its forced winding with the engine 5 , In the first case, the triggering and retrieval is a safety measure. The others are the rule for winding the rope. This solution does not require remote control mechanisms in the kite, but simple electromechanics in the ground station.

Of the Dragons in sled form (sled) consists of three or more (in this Fig one behind the other to think in depth) arranged scales. The change of flight characteristics for the descent can again through Solve lower Balance parts as described above or complete scales done (e.g., dissolving the outer scales; the innermost remains unchanged fixed on the pull rope, the kite lifts its side wings).

The Masts should be possible high, of the order of magnitude the medium altitude to be the dragon. You can be graceful, the bending forces become collected by control cables. The working rope remains essentially vertical, the dragon stationary. Approvals should be easier, too Therefore, in a conceivable accident, the tearing of the Work ropes, even more ropes to hold the dragon. At a Dragon Park can single masts at the same time for Several kites are used. You can also use a pulley over pulleys guided Ropes merged become. There you can they are wound on a reel with several tracks and one drive common generator (or a pump or other equipment). In this case, the kites rise and fall synchronously. For independently running Reels can The dragons run in their own rhythms, either with one generator each (or other device) or acting on a common with appropriate gearboxes. Such a coupling of several kites saves costs and can deliver the energy more evenly. Dragon parks can be occupied relatively narrow. However, that is the need for parks significantly lower than wind turbines. In Contrary to these leaves a kite can easily scale with ropes and ground stations, i.e. very small and very tall, with upward cost per generated power.

4 represents another solution, a dragon ferry.

The Dragon 42 is "threaded" through a hole on a guide rope. The guide rope is passed through a helium-filled balloon, the lifter held in the air. It is shaped so that it offers low air resistance and is as high as possible.

The kite hangs again over balancing pieces on the working rope, which as usual is wound on a reel. The wind drives the kite up to a stop 45a , There the kite for the sinking phase is changed with the impact force and the braking impulse. In this case, a grid is triggered, the cross brace kinked, the kite folds like a butterfly and slides, supported by the rope motor, down. At the bottom stop, the kite is unfolded again, the crossbar snaps in, it rises again and produces energy.

The ground station is basically constructed as shown in Figure 1, but the return motor falls away and the reel is a simple role.

The arm 60e is adjusted depending on the chosen kite and lift, possibly also on the prevailing wind, so that it is approximately vertical. This is between the arm 60b and 60c a swivel inserted through which the rotation of 6b gimbal is transmitted, in the simplest case by a flexurally elastic rod. (The default on the wind force can be done electromechanically in all solutions). Generally, by choosing a strong lifter, or by tethers as in 3 described to aim for the smallest possible lateral offset of the kite.

If the working dragon 42 driven by the wind at the top stop 53 arrives will be in 60a the mechanism triggers the axis 60b turns 180 °. This can be done in different ways. For example, by the impact energy of the kite at the upper stop, or the energy of a tensioned at the lower stop spring, which is just snapped up, or on 53 Attached electromechanical encoders. The dragon turns upside down, as in 5 sketched on the left, the wind and its own weight push it down, where it hits the ground station again on a stop, it is turned into the climbing position, possibly the internal spring tensioned, he rises again, etc. This can also be electromagnetically supported.

To do no damage at too high Dragon speed, the bottom stop is spring-mounted. 60c beats on the double rope feedthrough 55 and is braked there springy. The same happens above: The rope thickening 59 encounters 55 up and spring up the dragon again. The cable bushings are in the simplest case double-funnel-shaped smooth eyelets or usual double-pair rollers for such purposes.

The Alternator turns right and left and generates in both Directions are voltage regulated energy, which is delivered via a flexible cable directly is fed into a battery.

The ground station is rotatable on a Bo denanker stored. The support rod for the resilient stop is pivotally mounted on the ground station, its angle of attack is the angle of the rope. The entire ground station is pulled by the Seilführungsarm pulled automatically in the prevailing wind direction, so need not be tracked.

The working dragon 42 can in principle be any type, he only has to pull his head down. Instead of the rotation of the kite, the mechanics can 60a However, the ropes leading to the dragon shorten and lengthen with the same effect, namely to switch between up and down drive.

To the role 51 For example, a dynamo may be docked, firstly to assist in electromechanically shifting the kite above, or to provide power for firing the lifter.

• Rest like 5

Instead of the lifter, a mast lashed with ropes is set up. The dragon moves like in 5 described between the two attacks 53 and 54 up and down. The mast is between the rope mounts 73 rotatable, so that the kite can always stand in the wind. From the role 52 its rotation is transmitted to the ground station via a pole in the mast or another rope loop. Such a plant would be stationary like the wind turbines, but could be built much cheaper: a mast with ropes is much cheaper than non-rigid towers, a Stoffdrachen is much cheaper, fluid mechanics much more efficient than the elaborate heavy propellers, in the wider wind range and could easily much higher to use the stronger winds. He would be more reliable and would not shred birds.

The same applies to a system according to 7 ,

The detail on the right shows the upper roller combination seen from above at the moment of the passage of the kite holder 60b

The dragon, pictured here as a flat dragon, is not changed at the top and bottom, but runs on one side of the rope loop 61 up, is guided over the roller combination similar to cable cars, then stands on the head, runs down the back of the loop. At the lower role combination the reverse happens, the kite runs up again and so on. The kite continuously generates energy. You can also attach several dragons to the rope by using the rollers 51 and 52 makes large or 2 installed side by side or eg in middle mast height with other roles the rope loop spreads, so that the running dragons do not collide with the down-running. (without drawing)

The same principle is in 8th realized.

Instead of the pulleys 55 in 7 is easier just a half-shell placed on the rollers, the falling down of the side to the rollers 51 pulling rope 61 prevented. Top right as a detail shown, as a view of the upper deflection from the top right.

In the picture itself is the staff 60b When circulating around the role indicated in the top position, ie in the turning point of the dragon. The ground station 41 consists of the ground plate (or ground cross) fixed with several ground anchors 9 a frame rotatable about a vertical axis 41a in the around a horizontal axis in the joint 57 the device is suspended. It consists of an arm 80 to which the lower pulley with rope guard is mounted as above, and the alternator 6 that with the axis 81 and the pinion or friction wheel 83 the rotation of the roll 52 absorbs and their energy with the cable 82 is transmitted to the consumer and storage. The center of gravity of the device is located in the fulcrum 57 , so it adjusts itself to the inclination of the rope without any counterforce, just as the whole arm turns by turning 84 adjusts to the prevailing wind direction. Of course, detailed solutions between the figures are interchangeable.
