  • A kite consists of part and aspect sets where each set type could have many members:
    • wing set
    • bridle set
    • tether set (connectors, swivels, surface, interior, compound parts, conductions, ... )
    • resistive set (which could be another wing set (soil anchor, person, plants, hydrofoils, vehicles, etc.)
    • control set (pilot, autopilot, passive, active, mechanical logic, programs, sensors, transducers, ... )
    • purpose set (tasks, applications, motivations, meanings, )
    • media set (air, water, soup, soil, plasma, photon stream, molten metal, magma, glass, sand, chemicals, food, trash collection, etc.; and characteristics of the media)   A kite system may operate at once in a combination of media (e.g., upper wing in air with resistive set being a hydrofoil; here the tether could be partly in air and partly in water.)
    • history set (production, inspection, testing, sales, use cycles, wear, aging, repair, decommissioning, reflection, analysis, comparison, significance, users, affected parties, environmental impact, ...)
    Kite: A wing on a string anchored in flow.*

    ++++++++++ NOTES ++++++++++++++
    * Lord Byron Put It So-
        The Kite Is Poetry.**
        But Its Also A Thing;
        A Wing On A String
        Anchored In Flow,
        Or Stuck In A Tree.
    ========================

    ** Byron defines poetry as "a kite twixt life and death", whereby the poet's spirit is wind. The AI field of embodied computation concurs, the kite is an "animat" made of form and matter in an energy field. Poetic handling of ideas is that powerful, after all, Byron's daughter Ida invented computer programming. A weird kite agency explains the kite's profound influence on teenage Newton and his ultimate Laws and kite-aeroengineer-turned-philosophical-superstar, Wittgenstein. We recall that famous rainy summer on Lake Geneva with Byron when Mary Shelly wrote Frankenstein: A Modern Prometheus, and how Victor Frankenstein's kite was the sci-fi plot device, a technical means by which lightning was brought down a wire to animate the monster, the echoed theme of "a kite twixt life and death".

    =========================

    The Kite as "companion to the stars".

    The foundational Pocock kite text features verse I first took to be from Lord Byron's play, The Two Foscaris, but instead came from Mary Mitford's Tragedy. Mitford's Foscari relates a childhood Maslovian peak experience, a magical high-altitude kite flight, the remote kite rhapsodized as "companion to the stars".

  • A kite is a trinity: a tether segment and its two end sections.                  
  • A kite is an airfoil and a coupled resistive tethering embedded in water or air or other media. 
  • A kite is an airfoil on a tensed line in a fluid.
  • A kite is an integrity of three parts: tether set and its two end element sets.
  • A kite is a "tethered glider"    (per a reference book that apparently incorporates the resistive anchor set in the tethering function) 
  • A kite is a tether-set-coupling of wing sets in moving media.
     
  • A kite is a wing on a resistive line; a description that presumes nothing about the material, shape or design of the wing itself. The wing can range from a rigid body, much like a sailplane, to a fabric structure that gains its shape by the force of the wind. Trade-offs exist in both cases, and the best kite for power generation is still an open question.
  • A passively-autonomous AWES [[Ed: kite system]] can be formally understood as a coupled phonon-graviton automaton acting under quantum computational control.  ~DaveS AirborneWindEnergy/message/8971
     
  • A kite is an object having a wing at each end of a coupling tether; one wing may be designated as "mooring" or "anchor."
  • The kite itself is an incredible totally embodied paleo-cybernetic device.       ds
  • I am a kite.    
  • Trees are kites.    Trees are kites that bear kites that become glider kites.    
  • Leaves are kites.
  • A kite is a wing on a resistive line.
  • A kite is an airfoil stayed in flight by reaction enabled by a resistive line.
  • A kite is an object that uses the kiting principle.
  • A kite is a system of parts (wing set, tether set, resistive or mooring set).
  • A kite is a kite system.   A kite system is a kite.
  • "A kite is a tethered airfoil."
     
  • Inescapably a flying simple kite is already a converter of energy, a heat engine, an energy generator, a holder of energy, a channel of energy, a radiator, a machine doing work, a giving system, ...   It is the task of AWES developers to form kite systems that radiate gifts and energy in formats that solve practical tasks.  Though a simple kite is an AWES with humble but noble gifts for humans, advanced AWES have the potential to bless the world in even more ways. Era K3 is the era of advanced AWES wherein kite-energy serves well.
     
  • A kite is a "flying harvesting device" consisting of anchor system, tether system, and wing system. The kite is harvesting the wind's kinetic energy.
  • "A kite is an aerodynamic vehicle restrained by a tether."
     
  • Notice that the mooring or restraining scene could be a moving mooring, even moving through the air or moving through the water; fixed mooring are common, but moving moorings that supply restraint to aerodynamic vehicles also are significantly present (gliding parachutes, hang-line-using hang gliders, paragliders, dynamically-soaring couple-kite systems, paravanes, and more).
     
  • Kite.--Fundamentally a kite is a surface or series of surfaces, either flat or curved, which  provide with a restraining attachment having the nature of a string or line. The surfaces and line are arranged in such relations that when the kite, held in restraint by the line, is exposed to masses of air in motion, the surfaces are subjected to wind pressures which sustain the kite in mid-air, where it assumes a position .on of equilibrium.  Marvin in April 1897
     
  •  Frequently "kite" is used with nearly full focus on the wing of a kite, whereas the tether set and resistive set or mooring set are essential for a kite (in the unabbreviated sense). The wing disassociated from a kite's tether and resistive set is no longer a kite, but a non-kite object that may operate as a glider or object of art. A kite becomes its active self when actuated using the kiting principle; outside of the action under the kiting principle, the collection of parts (wing set, tether set, resistive set) is a potential kite and not yet an actual kite.  The three essential parts of a kite  could be operating in distinct media; for instance the wing set could be mostly in air while the the tether set could be water while the resistive set is mostly in the soil at the bottom of the water; the most common, but certainly not the only, situation is where the wing set and tether set are in the air while the resistive set is the terra firma. A full appreciation of kites could examine all of the possible combinations of media for the three essential parts of a kite.  Notice also that the wing set of a kite could have some elements of that set in one media while other other elements of the wing set in distinct other media; likewise for the elements of the tether set and of the resistive set.  Further, for instance, a tether element of the tether set might share more than one media, say partly in air and partly in water.  And it is to be noted that the tether set itself provides part of the resistance that is the role of the resistive set of a kite.  The count of elements in the part sets of a kite may vary from 0 to high number; when zero, then we may be looking at the "empty kite" which may not be considered yet a kite; however, such is not always the case in a sense, e.g., what appears to be just a tether alone in a medium  could be a kite all by itself.    Media is nearly always a complex, however, a dominant media is noted; e.g., air  most frequently involves photons also.
     
    Kite
    Wing set Tether set Resistive set Media set Comment
    line portions line portions line portions 1: Photon space Here the kite is a single object, perhaps homogeneous, perhaps not. Dynamics of one end operate as wing; dynamics of the other end operate as resistive set; the section between the ends operate as a tensional coupling tether between the wing and the resistive mooring.
             
             
    1: one wing element 1 : one string 1: a complex 2: air and complex of body and soil This kite category is perhaps the most common and found millions of times over each year around the world. E.g., a single-line Eddy or Malay kite held in the hand of a person. The "hand" is to be understood as a complex where friction with body and soil provide the resistive set; if there was no friction at the feet of the person, then even a tiny wing could pull the person an only air resistance on the tether and body would provide the essential resistive set.
             
    50 wing elements complex of 100  lines joined to two final lines 2: one a boat and the other a land anchor Air for 49 wing elements and water for one wing element/ This kite is a complex and begins to indicate the vast richness of combinations that are possible for niche applications.
    #? #? #? #? Etc.  The count of describable kites is practically limited only by the capability of the agents, tools, and resources used in describing.  Among the trillions and more potential kites are kites that will be designed,  built, and operated for niche applications.
  • "A kite is an aerodynamic vehicle restrained by a tether."  Miles L. Loyd   
    • Notice the three sets: 1: wing set (aerodynamic vehicle which could be complex), 2: tether, 3: restraining cause. Notice that the restraining cause occurs at the other end of the tether or along the tether. Without the restraining cause, then the tether does not restrain the wing set.  Let the aerodynamic vehicle be seen as a set of elements symbolized by w. Let the tether be seen as a set of elements symbolized by t.  Let the restraining cause be seen as a set of elements symbolized by r.    Then (w,t,r) allows to be seen a kite.  If (w,t,r) is with an r that is freely fallying through the fluid, then one sees a paraglider type of kite (allowing any sort of wing elements in w and as many tether elements as wanted in the t).       ~JpF

  • A kite is the sum of its parts; sometimes in abbreviation people will look at its wing part and say: "kite"; but the whole kite is the sum of the parts that let the be a kited aircraft where the kite's part string(s) and the kite's part resistive system permits the kite to be kite. The abbreviated wing only provides a glider; but add the engine assembly of string and the resist element and have the parts needed for kiting.  When one hangs a "kite" on the wall without a string and the resistive part, then mechanically implied is that just the wing part of an intended whole kite is set on the wall.  Using abbreviation is great efficiency; yet to actually have the "kite" be its full self, get the full kite present and set it in the air for some kiting action.

    Author of Amazing Grace

    "The Kite and its String: is a poem.   The possessive is deep. Kites have their parts, the essential parts are wing, tether, resistive element.  Resistive element could be the moving earth, a moving hand, a moving car, a moving boat, a mass that is falling to the attraction of gravity, a wing that flies resistively, so as to give tension in the string in order for the main wing to kite.   Remove the string and the resist and have no more kiting, thus no kite; just wing.
     
  • A forum with its resistive set of rules flying threads that hold winged conversation blown to lift by the imagination of participants may be thought of as a metaphorical kite.    Inspired by the post of Jonty Lawson, November 7, 2011.  Of course, this kind of kite is a big contributor to human society and to history.   Keep these kites flying!
     
  • Tigner expresses in a patent:   
Kite 14 CFR 1.1
Kite means a framework, covered with paper, cloth, metal, or other material, intended to be flown at the end of a rope or cable, and having as its only support the force of the wind moving past its surfaces.
Source: http://aviationglossary.com/kite-14-cfr-1-1/  [This falls short when one wants to include many systems that are kites; e.g. those wings tethered by two or more lines that even may not be rope or cable; also, the short definition misses wings that have not frames.  And "intended" is missing the mechanical reality that intention is not mechanical. Aim for having kite be the mechanical system that includes wing set, tether set, and the resistive set; the resistive set makes it possible for there to be a difference in the stream and that flow that is deflected which permits the kiting dynamics to occur.

  • kite is a captive aroplane
== A kite is a building so light that it will rise up and fly or float when the wind blows its wing set constrained by its anchored tether set. The building has a wing set, tether set, and anchor set.
A kite is a collection of tether-coupled wing sets.   Examples:   W1___W2  or    WS1____WS2___WS3         Very many more arrangements may be made to have trains, arches, domes, meshes, trees, coteries, etc.   Each wing set may consist of one or more wings; even consider the empty-wing-set in a complex kite. Without the tether set, there is no kite. Without the coupling of the wings using the tether set, there is no kite. Consider kite-system anchors as "wings" even if the "wing" is a soil stake, etc.   A kite may be put to work fulfilling a task or many tasks.  ~JoeF, 4 Oct 2013.
set, sets, set theory, empty set, set members.    Kite may be seen as a set of wings and coupling tethers.
Regarding the birds called "kites":

A kite is a system of tether-coupled wing sets in fluids.
Some corners of the universe would like to overly restrict what a kite is or is not.

In a NAC art project, they did not want to respect the kiting principle in low L/D kites; they insisted that a kite below a certain L/D was not a kite. To many others, that is silly; why not just let the L/D ride full spectrum and have very-low L/D kites, medium L/D kites, high L/D kites, etc. It would not hurt to embrace the full spectrum; there can be very special uses for low L/D kites.   Here is their quote: "It must fly in a reasonably steady fashion at an angle of 15 degrees above the horizon for a sustained period of time to be considered a "kite""   That also overly restricts the motions of the kite; why not let in the full spectrum of steadiness from no steadiness to high steadiness? There are some very practical uses for very unsteady kites; recommended: just embrace the full spectrum from very unsteady to very steady!    Also, why restrict to the time? No need, just respect short time or long time for steadiness; all are welcome to world of real kiting!  It is just that each particular behavior has its own uses.     We vote for a positive wider acceptance of what a kite is!!! 

The same org was overly restrictive in their definition of a kite:  "A kite is a flying device that remains tethered to a fixed point or to the person flying it."  Too tight!  Easily there are wonderful kites that are flying when attached to inanimate non-fixed points, like when a kite system is dragging its long line in the ocean as the system travels hundreds of miles; the line in the water gives resistance but is not a fixed point. There are other instances.   Better to simply have types of kite systems rather than lose kite systems by overly restrictive definitions.

  • A kite is an aircraft or watercraft system consisting of wings tethered to an anchor system. Frequently a wing of a kite is referenced as "kite." A kite may have more than one wing, more than one tether, and more than one anchor.
     
  • Kites are members of AWES.   A kite is an AWES.  Not all AWES are kites.
     
  • A kite is an aircraft or watercraft system consisting of wings tethered to an anchor system. Frequently a wing of a kite is referenced as "kite." A kite may have more than one wing, more than one tether, and more than one anchor. Anchors may be moving or fixed and may be seen as wings themselves. Smartly integrating parts and mode of operating a kite system will alter the impact the system has on its environment. AWE emphasizes kite systems that have practical impacts on the health of earth, plants, animals, and humans. The Era K3 has AWE flourishing.

  • A kite is what kite people have in focus most of the time they are dealing with their kite interests.
     
  •  An AWES as kite is what is mostly in focus by people developing airborne wind energy systems.
     
  •  Though a simple kite is an AWES, it is to be appreciated that non-simple kites are AWES. 

    Kites that employ robust energy-take-off parts or PTO systems are non-simple AWES. PTOs might aim at sending electricity beyond itself, or sound, or heat, or rope movement, or release of lifted masses, etc. 

    Also, kite systems that might have non-simple means to accomplish special non-simple tasks, easily are found to be non-simple; non-simple subassemblies might be the multiplication of wings,  working tag lines, multiple tethers, specialized surface treatments, provisions for living quarters, arrangement for manufacturing goods, robust adjustable lift for maintenance of purposed structures, etc.                ~ JoeF, March 5, 2014
