How a system extracts energy from the wind and transfers energy to systems. One typing parameter the position of the generator or pump or tasking line or device. Another typing parameter looks at the tethers of the tether set of the kite system are used; the tethers holding the kiting wing elements aloft may be used in various ways to form types; tethers may simply hold working wings aloft, or they may be pulling loads on the ground, or being towing loads of gold by pulling loads or grinding things. Some types are distinguished by fast motion transfer or slow motion transfer. Typing of crosswind kite power system is a matter of the nature of the wing set where the number of wings and types of wings matter to designers and users; A wing set might be in a train arrangement, stack configuration, arch complex, mesh dome, coordinating family of wings, or just be a simple single-wing with single tether. Types of crosswind are also distinguished by scale, purpose, intended life, and cost level. Typing by economic success occurs; is the system effective in the energy or task market or not? Some CWKPS are a type called lifters; they are purposed just for lifting loads, The type is frequented by the use of autorotating blades that appear then to look like helicopters. A single crosswind kite power system (CWKPS) may be a hybrid complex performing aloft energy generation while also performing ground-based work through tethering pulls. The crosswind kite power systems that involve fluttering elements are being explored in several research centers; flutter is mined for energy in a few ways. Researchers are showing types of CWKPS that are difficult to classify or type.
In the systems of this type of CWKPS, the pulling tether set is one of the most important elements in the atmosphere. In this type of crosswind kite power operation, the design of the resistive objects (people, boards, hulls, boats, ships, water turbines, air turbines, other wings) makes for further types. Crosswinding of the upper flying wings provide power to achieve certain final objectives. Kiteboarding, kite windsurfing, snow kiting, yacht kiting, freighter-ship sailing, kite boating, and free-flight soaring and jumping. A collection of researchers has explored the historic free-flight parakite realm to where to crosswind flying of the systems’ wings would be able to free-flight in the atmosphere; This is a kite-string set with a wing and a wing as the resistive anchor set; control of the separate wing set, especially in crosswinding efforts the power of winds in different layers of the atmosphere.
In the systems of this type, an electrical generator, pump, or tasking line is installed on the ground. There are two subtypes, with or without a secondary vehicle. In the subtype without a secondary vehicle, “Yo-Yo” method, the tether slowly unwinds a drum on the ground, the crosswind, that is, left-right of the kite system’s wing the wind’s ambient direction, along various paths, eg, a figure-8 flight path, or optimized lemniscate paths, or circular paths (small or large radius). The rotating drum rotates the rotor of the generator or pump through, perhaps, a high-ratio gearbox. Periodically, the wing is depowered, and the tether is reeled in, or, using the crosswind for a constant pull, the tether is re-connected to a different section of the drum while the wing is traveling in a “downwind” cycle. In some systems, two tethers are used instead of one. In another subtype, a secondary vehicle is used. Such a vehicle can be a carousel, a car, a railed cart, a wheeled land vehicle, or even a ship on the water. The electrical generator is installed on the vehicle. The rotor of the electrical generator is brought in by the carousel, the axle of the car, or the screw of the ship, correspondingly.
In the systems of this type, one or more flying blades and electrical generators are installed on the wing. The relative airflow rotates the blades by way of autorotation, an interaction with the wind, which transfer the power to the generators. Produced electrical energy is transmitted to the ground through an electrical cable laid along the tether or integrated with the tether. The same blades are sometimes used for double purpose where they are positively driven by cost of electricity for launching or special landing or calm-air flight-maintaining purpose.
In this type, the electrical generator is installed on the ground and has a separate cable or belt, which is used to transfer the power of the generator to the ground. The separate belt extends to the speed of the wing. Because of the high speed of that belt, the gearbox is not required.
In this type of electrical generator, the pump, tasking line set, or lever is installed on the ground of the wing and driven by a fast moving crosswinding flying wing set. Examples are found in the research centers of several universities and kite-energy research centers.
Several research centers are exploring twin wing sets employing tether pulling of upwind ground-based loads where the crosswinding wing sets use air-lighter-than-air devices to ensure flight in case of lulls in the ambient wind.
Many in-public-domain patented LTA kites to hold bladed turbines using autorotation to drive flown generators.
When a fluttering element is fluttered, then fluttering may be harvested for energy to power various loads. In flutter, the wing element travels to a crosswind and then reverses to a crosswind in a opposite direction; the frequency of cycles of reversed direction is high. Flutter in traditional aviation is usually considered a bad and destructive dynamic to be designed out of an aircraft; but in CWKPS, a flutter is sometimes designed into the kite system for the specific purpose of converting kinetic energy to useful purposes; the fast motion of flutter is prized by some kite-energy systems development centers. Harvesting the energy of flutter in kite systems has been done in several ways. One way is to convert the flutter energy into a sound, even pleasant sound or music; one person or a crowd of persons; bird-scaring has been an application. Jerking tether lines by the kite-flown fluttering elements to drive loads to make electricity and have been explored. Pumping fluids by the use of flutter-derived energy has been proposed in the kite-energy community. And having the fluttering wing, and then electricity can be generated immediately; part of the fluttering wing that is formed to be a magnet flutters by conductive coils forms the parts of the electric generator.

CWKPS are used to move over ice, snow, land, ponds, lakes, or oceans. The movement of objects may be for various reasons: recreation, sport, commerce, industry, science, travel, mine-clearing, defense, offense, plowing, landscaping, etc. Kite boarders, land sailors, kite surfers, kite boaters, yachts, ships, catamarans, kayaks, power kiters, kite buggies, kite skiers, kite water skiers, etc., is keeping kite- wing manufacturers busy. SkySails is a leader in saving fuel in the shipping industry by using CWKPS.
In this type of CWKPS the fast-motion of the flying blades or wings harvest the wind energy to power the lifting capacity of the system. Massages are sometimes close-coupled with the wing set; at other times the mass is distributed along the tether set. A military use of this type involved the rotary-wing kites that appear to be helicopters (but are not) tethered by the kite line; a human observe gets lifted to high points for observation purposes; Some of these were used in submarine operations with the submarine’s towing motion providing the apparent wind for the CWKPS. One example is the Focke-Achgelis Fa 330 Lift-and-place or lift-and-drop uses occur in this type; mass loads are lifted and then placed or dropped; this is done sometimes to overcome barriers or to save ground-transportation fuel costs. When the mass is lifted is a generator coupled with the crosswinding blades, then the AWES type is changed; this change is the foundation for the focus of some wind energy companies; David Lang is carefully modeling AWES in coordination with Grant Calverley.
In this type, rotary cross kites drive rings around a guiding tether line. Since the rings are tied together and in tension, torsion can be transferred from the rotating kites to a ground generator. Rotary kite motion around a hand lifted tether can rotates the tether itself, a rotary tether set, or lines fixed across the axis of the hand lift tether. On 15 December 2015 this method was the first to successfully complete the someawe.org 100 * 3 challenge For a prototype demonstration
In all types of the crosswind kite power system, the useful power can be described by the Loyd’s formula: where is the effective gliding ratio, taking into account the tether drag. Example: a system with a rigid wing, having dimensions 50 mx 2 m and G = 15 in the 12 m / s wind will provide 40 MW of electric power. Where is a quote from the example? The Loyds papers formula does not show it in thowse simple terms. What is CL What is Pa Where does 2/27 come from? How can this be scaled to the loyalty c5-a example? 50Mx2M = 100m ^ 2 2/27 = 0.07407407 pa = 1.225 kg / m ^ 3 P = 9.074074 * CL * G ^ 2 * V ^ 3 g ^ 2 = 225 v ^ 3 = 1728 P = 9.074074 * CL * 388800 P = 3527999.97 * CL CL = 0.0882 OpenVSP can be used to model designs of CWKP systems. http://hangar.openvsp.org/vspfiles/350
Depending on the final application of a crosswind-kite-power source, the appropriate kite control methods are involved. Human control is exercised during the study of crosswind stunt kiting and kiteboarding; the same source for some electricity-producing crosswind-kite-power source, eg, by Pierre Benhaiem of France. When the crosswind-kite-power source becomes too large to handle, then they are both fully human-assisted devices and fully autonomous robotic control systems. Also, there is a fully passive crosswind-kite-power source where a system does not permit the control of a robot. Actually, anyone can see a kite toss left and then right in constant motion is seeing a primitive passively controlled crosswind-kite-power source.
Some sectors of crosswind are already commercially robust; the sport low altitude traction industry is one of those sectors; crosswind sport toy kite power systems at low altitude must remain safe. But the sectors of high altitude larger CWKPS aiming for utility-scale electrical production to compete against other forms of energy production Some of the challenges are regulatory permissions, including the use of airspace and land; safety considerations; reliable operation in varying conditions (day, night, summer, winter, fog, high wind, low wind, etc.); third-party assessment and certification; lifecycle cost modeling.
The early 1800s witnessed George Pocock using the control of kite system wings to crosswind to good effect. In the early 1900s Paul Garber would produce high speed wings for two. Crosswind kite power was brought back into focus when 1980. In 1980 it was not possible to create an economic control of a kite system. control of crosswinding kite systems had been ancient. With the advance of computational and sensory resources the control of the wings of a kite system has become not only affordable, but cheap. In the same time significant progress was made in the materials and wing construction techniques; new types of flexible kites with good L / D ratio have been invented. Synthetic materials suitable for the wing and tether became affordable; Among those materials are UHMWPE, carbon fiber, PETE, and rip-stop nylon. A large number of people in kitesurfing, kiteboarding, kite buggying, snowkiting, and power kiting. Multiple companies and academic teams work on crosswind kite power. Most of the progress in the field has been achieved in the last 10 years.
Current trends in CWKPS sectors will have their follow-on stories. Enthusiasm seems to be at a high level among others in the crosswinds. CWKPS is a well-established and well-established system for the production of fuel oil. Objectives for the future discussed in the literature CWKPS facing toy, sport, industry, science, trade, energy for electrical grid, sailing, and a host of other tasking applications. Forecasting, power generation, CWKPS, power generation, CWKPS and adopted; CWKPS will be advancing into the future as well. The variety of configurations of kite systems is expected to grow; However, some of these formats are expected to eventually become shine. Placed wing elements that fly to crosswind on huge lofted rope-based arches or even net domes is being researched.
These are two sectors of crosswind kite power patents, those that have placed some technology in the public domain and that are within the protection of validated claims. Crosswind kite power teachings in each other are part of what is considered by the crosswind kite power research and community development and interested readers. * US4708078 Propulsive wing with inflatable armature by Bruno T. Legaignoux, Dominique M. Legaignoux, with priority date of Nov. 16, 1984. This patent activity was part of the growing crosswind power surge that is still happening. The inflated leading edge and inflated struts with aggressive crosswind motions and water relauchability. Similar structure technology is being used in some AWES crosswind kite power research centers around the world.
Crosswind kite power systems, sport power kites, and experimental-handy sizes; proposed by research centers are a huge utility-grid-power-feeding sizes. The power gained in the toy size is used to excite product users; two-line and four-line crosswind toy kite-power systems fill kite festival skies. Serious sport crosswind kite power systems drives the movement of athletes around race races in local and national competitions. Experimental-handy sizes of crosswind power systems are explored while furthering research towards utility-scale systems.
Crosswind kite power has been put into various uses throughout history. And the variety of devices that produce crosswind power have a historical progression. A simple kite system with passive crosswind production is more powerful than kite systems. For perspective, crosswind kite power and crosswind kite power.
Kite-power systems dedicated to operating without its energy-harvesting elements to CWKPS. Examples help to clarify the two branches of kite-power systems. A simple symmetrical two-stick diamond kite let out to downwind flight the system’s tether pulls to turn an at-ground generator shaft is producing energy for use by flying downwind without flying to crosswind; such is a non-CWKPS. Some hefty downwind kite-power systems (DWKPS) are proposed by serious researchers; some DWKPS instruction is found in the patent literature; one trend involves the opening and closing of pilot-kite-lifted opening-and-closing parachutes to drive generators. Notice that some CWKPS, such as Jalbert parafoil working in figure-8 patterns to turn a ground-stationed generator, could be commissioned to operate fully without flying, and the resulting kite-power system would then be a DWKPS. Differently, the CWKPS proposed by users of the CWKPS. Magenn Power’s flip-wing kite-balloon is a DWKPS. Similar flip-wing rotating wings are DWKPS, eg that taught in Edwards and Evan patent. Benjamin Franklin’s legendary pond-crossing by kite power was a simple DWKPS; he was simply dragged downwind by a downwind-flying kite. A non-CWPKS is a historically illustrated by a kite-power harvesting system such as was used by Samuel Franklin Cody for man-lifting with the crosswind. CWKPS proposed by users of CWKPS.
