    Subject: Re: Winchless, Drumless, Reelless Kiting
    Thanks for the question.    Short answer: Yes, keep the tether set, else there is no kite. Kite requires wing set, tether set, and reaction or resistive set (which could be another wing set). 

    Tether set and resistive set remain to make a kite system. The topic regards resistive set as not having reels, winches, drums, but rather just other resistive members. The most common example is a fixed soil anchor; have lines out to the wings; fly the system for practical works; have no winch or drum or reel in the system. 
    Another example is a bag and hand; collect the line of an elementary kite system into a line bag or box or pail. 
        In larger scale, consider AWES without having a winch, drum, or reel.  Consider other means of line handling. Consider line lay on ground on along raised way. Have control and kill lines. Have remote controls for wing parts. And much more. Down the AWES without winching or reeling or drumming the line set. Consider controls that bring the wings down. Consider releases into glider means for the wings in some downing choices. Consider gliders morphing to kite systems by dropping lines to anchor points. 

    Much adventure. 
    Some teasing matters:  No line wear from drumming or reel or winch interface. No expenses for the winch system. And more.   
    Open for the adventure.

    Subject: Re: Winchless, Drumless, Reelless Kiting
    Yes, those two need not use a winch, drum, or reel (w-d-r). But those may incidentally use such w-d-r. This topic thread would explore those two systems without w-d-r. 
        One visual would be to set a soil anchor, lay out 200 m of tether, attach a wing at the far end; then either help the wind or let the wind launch the wing in kited mode.  No w-d-r.    Then consider just what practical works one wants to achieve with such a basis. 
       You linked us to an artist versin of Hydro Kite that was a water-air FFAWE system with mid-tether cabin that might settle to water for a water-water-air FFAWE system.  Such could launch and run without use of w-d-r. Explore the new challenges and new total scenario in the no-w-d-r arrangement and operation would be part of this topic thread.

    Subject: Photon AWES

    Let the stream be photons or plasma or other special radiations. Let the space be small on-earth spaces or let the space be outer space in various regions.   We have mention this before but have not dedicated a topic thread; this thread might collect study and discussion on AWES where the "A" is not water or earth atmosphere, but photonic streams.  And the topic is not simple sailing is being explored, but rather FFAWE with the "A" as the photo stream.  Resistive set, tether set, and wing set  ... still for kiting in the photon stream. Or fixed anchor: say fix the anchor to a comet or planet or  asteroid.   We had entered a description into the asteroid-repathing project using a photon AWES; the kiting principle would gradually veer the asteroid from its first path to new path. 


    Sailcraft, not a kite: In 2010, the Japanese Aerospace Exploration Agency (JAXA) successfully tested a solar sail, called IKAROS (InterplanetaryKite-craft Accelerated by Radiation of the Sun). Their name had a traditional focus on the wing of common kites, but what they had was not a kite, but a wing that mimics the shape of wings in some common kite systems.   However, add tether and another wing for a FFAWE, and the name IKCAROS could better apply. 


          Tether wings that interact with photon streams, say our sun's radiation. And say anchor those wings to other wings that veer enough opposingly to result in a traveling and even energy-mining flight through space.


          Wings?   Tethers? Anchor system (could be wings)?  Operations? Purposes?

    Thanks, DougS.    
    Fun!
    1973. 
    Three-day bow-sprit kite (no spreader boom). The triangle control frame appeared strongly by W. Simon for hang gliding in 1908.  Nylon ripstop sail was seamed for us by Eipper. Mike Koman and I put the frame together in my Venice, CA backyard. From sketch to flight ... without testing: three days. Flight sequences started at sunrise and ended at sunset to please photographers. Simi Valley ..hills.  Shower scene took 18 hours. Skin was deeply irritated by the many shoots ... lather of their product. 
    FFAWE with upper wing tethered to resistive set (another wing: self). 
    No winch, no drum, no reel. Free-flight kiting. 
    The $ residuals on the commercial: .. about $7000 of 1973 dollars:: used to buy printing press
    to continue publishing kiting and hang gliding (a form of FFAWE) periodicals: Low & Slow.   And Hang Glider Magazine (weekly).... Together: 218 editions ... from home and some small shop: all processes grunting into mailing, selling hand typing ... no computer, no Internet, etc.  Toll on family life. 
    I sent my copy of the ad to Ken de Russy for his hang gliding museum collection; he is the "Collector Guy" that won support from many in the HG community; he preserved the video and put the copy up that you linked.

    Hazardous inadvertent kiting

    Perhaps AWES workers, technicians, engineers, scientists, designers could play a role in lowering the incidents of hazardous inadvertent kiting.


    This topic thread is dedicated to study and discussion of hazardous inadvertent kiting. 

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


    Start: 

    ==  Loads hung from construction cranes kite in winds.  Unexpected gusts or unrespected winds result in some kiting that brings damages to loads, cranes, people, and structures. 


    == Helicopter-tethered loads ?


    == Signs tethered?


    == Unsecured AWES ?


    Today I placed an AWES in a shielded corner and the reel of line still wing connected.  "I'll be back in a few minutes."   I came back and the system was not to be seen.   I finally found the system 25 ft away around the corner of the house down the driveway. Parked system got up and was hazardously inadvertently moved in a FFAWE session all on its own. Fortunately the wing and line and reel snagged on items in my driveway. Matters could have been worse. The 50-lb test line and wing could have gone further to disturb power lines or traffic or cause incident direct to persons.  Fact: The shielded corner was not shielded enough! 


         Unrelated news today in Fullerton, So. Calif. ... homeless man on sidewalk pushing a metal shopping cart [link to AP news]  met with live downed power line and did not live through the electrocution.

    AWES teams will probably have a safety officer versed in electrical matters. 
    Each team member would probably do well to be well versed in electrical safety matters. 
    Atmospheric electricity as well as electricity produced by working AWES 
    form alerts at each outing. Weather, wetness, conductors, grounding, static, 
    sensors, alarms, loads, ..
        Visitors to AWES operations: animals, people, children, hikers, workers ...

    fr0gz asked: Slack in the tether will always be a killer, no?
    ==========================================
    Some answering: 
    The topic invitation is open to dealing with steady and unsteady winds, low velocity and high velocity winds. Have an AWES that does not have w-d-r in its operation; then explore how far one might get in a niche application.  The invitation is not taking merit from systems with w-d-r; kept such systems advancing to fulfill objectives. But within this topic adventure, keep w-d-r out of the equation and then move to solve and serve in particular ways. This is a polite invitation and not some directive or tall or short order; enter the game and see how it plays. Handle unsteady winds by various solutions that do not include w-d-r; handle tether slack by various solutions that do not include w-d-r.  

    Today slack occurred in unsteady strong winds in an experimental flight session with a simple kite system and nothing got killed while avoiding w-d-r. So, there is not a universal theorem about slack tethers up to the "killer" status.   However, there are operations with some AWES where slack tether is to be avoided; some early weather bureau flying took special care to avoid slack tether; they used w-d-r in their solutions; such would be outside the present topic.

    Thanks Joe:  By the time your concept of "Low and Slow" made it to Popular Science Magazine (Bamboo Butterfly, etc.) a couple years later. I made my first attempted hang glider from metal antenna masts from Radio shack, sheets of plastic and duct tape.  Never quite got off the ground til I purchased an Eipper with a 4:1 glide ratio for $450, flew it a few times, sold it for about the same amount to buy a motorcycle - I needed transpo.  That was in High School. :)

    Subject: Texas AWE Encampment Report
    There is an ongoing trickle of new folks at the 3rd Texas AWE Encampment at kFarm, just outside Austin. Most are casual observers but two excellent student-pilots from New York City just finished an intensive short-course in AWE and sport power kiting at kFarm.

    Shawn Tomas is a Grenadian kite master who began making and selling traditional Caribbean kites at age eight, served as a US Army heavy equipment specialist. He is a kite patent holder and is coordinating AWEfest in the New York area. Abel Cruz is a Dominican Republic born NYFD fire-fighter, rescue climber, emergency rigger, and sapper. He brings this world-class safety culture to help develop operational safety standards for the emerging AWE industry. Shawn and Abel will represent their respective Caribbean Island Nations to Sir Richard's Carbon War Room project, to include AWE as a key technology.

    The KiteLab Group Ground-School introduced core concepts and AWE-applicable FAA FARs. The skills and kites covered in flight instruction included kPower's KiteShip OL, NPWs from 1m2-32m2, and parafoils in training, racing and valved versions. Flip-wings and flygens were covered, as well as many specialized topics. They learned specialized kite rigging skills and reviewed and witnessed a variety of unique AWES experiments.

    Another notable new visitor at kFarm was Joel Gonzalez, of the Philppines, an intensely energetic media pro very excited to take AWE forward in the public eye. He is being trialed as a kPower exec, and is hoped to be the missing "Steve Jobs" of global AWE (which might have been Corwin, but for his tragic early death)

    The 1.2m2 looping foil under a Kayakite pilot was continuously rigged, and impressed everyone by reliably and consistently relaunching after frequent lulls. It has run now for five days more than half of the time in low-to-high fluky winds. Several loads are tested in rotation, but most of the early flight time is unloaded, to just tune and refine the rig's flying parts over many hours and conditions. Despite the small foil, the rig is powerful (even freakishly frightening) in a strong breeze, and tends to destroy our smaller prototype work-cells. Large looping foils will be very dangerous to kite-farm workers when sudden wind changes and inattention combine.

    A major design improvement is to add a bungee section (fisherman's "snubber") under the pilot-kite to cushion it from the shock-loads of the looping power-foil (CC BY NC SA). This allows the foil to be closer to the pilot-kite so that it orbits almost as high as the pilot's altitude. Elastic elements are proving essential to tame peak loads, allowing lighter more robust AWES, and they return most of the surge energy they absorb.

    A new Failure-Mode to document is hobby kites and prototypes spitting out sticks in high wind. The solutions are to reduce excess batten stiffness and reinforce pocket-ends to the standard of sail-makers. The aft-pocket-ends in the pilot-sled are uniquely stressed in a rare head-first "lock-out" crash, but the system has always just popped right back up. Minor pocket repair with Scotch Tough-Tape just takes a minute, and future kites will ruggedized as needed.

    More to report in follow-up posts...

    I did not intend to be impolite.  It seems to me that every tethered autonomous AWE implementation must be designed to survive unsteady winds.  Considering the many possible characteristics of unsteady winds, the solution would have to be incredibly robust.   I recognize that somewhere out there are folks who are far more clever than me, but this challenge is a real toughy!  I sincerely look forward to seeing schemes described here which manage to avoid use of winches, drums and reels.

    Subject: Loop Testing

    The system seems to work well, Its very nice not having to run and lay line. The kite retrieved and launched from the station. Once the kite is at altitude, I just pull the main string (which the whole assembly rotates clockwise around) (further the pull, quicker the kite loops) as the kite begins to do the "twist of death" all the way up the bridle, the orbital system unwinds the line. 


    Instead of quick bursts of power, this machine seems to rotate the kite quick enough to get more of a propeller effect... 


    I think there could be a lot of application for this. 


    This system does not require a pilot kite, but it cannot collect energy at a spot in between the mooring point and kite like Dave Santos's machine. This machine will have to collect energy post mooring.. like dragging a drouge through the water..Ive also been talking to Stephane about a paravane technology..

    Nice work and interesting new case of a "standing-eight" kite trajectory claimed as optimal, which we have little considered. Pauli Rautacorpi presented a closely similar orbit at AWEC 2011.

    In normal kite pilotage of a standing-eight, one must cant the bar or handles to avoid line-cross, but a vertical control bar can fly the pattern cleanly.

    Add the standing-eight to the common lazy-eight andTUDelft reverse lazy-eight to our figure-of-eight list.

    Hi Cleventine,

    Circle Loops are not faster when Eights count as two (lobes). Which is best may depend on operational trade-offs, not a bare mathematical edge. Claims contradict (Makani/Joby thinks loops win).

    Welcome again; we needed more Love Professors. Your AWE work is a brilliant start; can't wait to see how you ultimately riff on the Open AWE wave you have now found. We need help with perfecting the flying machines, AWEfest vibe, liberational kite anthems and manifestos, etc..

    Be sure to look up Jeremy Calvert of Kitebot (SeaTac). I'll be back NW via PDX in June. Maybe you can make and fly WSIKF 2014 in August, by the Lower Columbia, and meet the local AWE freaks. Radical sea-collectives range around your island, as well, if you want to kite-sail with scrap-rafts, umiaks, native canoes, hipster-yachts, ocean-kayaks, and so on,

    Right Up, Rock Out,

    No doubt, a checklist is always preferable,
    So what im getting at is efficiency. Less steps, less people required, less expensive.. etc 


    Some systems are just not practical with one person, say the kite needs to be launched/retrieved from downwind as winches/ whatever else needs to be monitored up wind. (just an example)

    Also Initial set up time. Why would you ever want a whole team for a job a single person should do.. Those extra hands are inefficient..

    Hi Vestwriter,

    This topic applies to misc AWES concepts like FFAWE* and kite vehicles, which do not in principle require active winching and reeling (but may include such elements secondarily).

    One common such winchless AWE example is commercial aviation flying to maximize tailwinds for almost a century. This largest of all AWE engineering cases clearly offsets fuel use, but is not the first AWE concept folks think of (unlike winching kites and aerostats),

    Well hey, the MFV doesnt use winches actively, (besides launching and retrieving) 


    By spreading pulleys apart I am able avoid actually having to use a wench.. That added benefit is that i can steer the kite independently of the winch! 


    Since im only really manipulating one line.. it will make the program to automate it much simpler in the future. 


    If you see in the video i am pulling two strings to fly the kite.. yet those strings are not directly attached to the flying lines.

    Subject: Re: Single Hand Operations
    Your topic is focused on "Single-Hand Operations" with more-than-one-person operations left to a different topic thread.   

    What are the AWE operation possibilities that may be operated by just one person?

    It seems that opportunities are uncountably infinite, but limited in implementations by time, space, funds, and more.  Will we allow large time spans for setting up? Perhaps one person could arrange things in an AWES kite farm over a matter of days, weeks, months, years.   And perhaps automation may be in the AWES farm set to need only occasional oversight by one person.   And will we allow decommissioning over a long period of time to allow the one person to carry out that sector of the operation? The tolerance for error and failure would need to be defined. Individuals as well as large team may may mistakes.    In all, I guess that more could be said once a specific AWES is fully specified; and if the particular AWES is designed within the safe and practical handling limits of one person, then we will be served up some solutions with clarity.   Today I handled three different sessions with an AWES that needed only one person for the full operations; ... a handy system; but I failed to notify a remote person where I was and what I was doing; such connection or teaming would have made the total operation a bit more safe. Buddy system?   Single-hand AWES operations ever entail risk sets to be managed.  The risk set could be made as clear as possible for owners of "single-hand AWES." A spelling out of what to do in case _X___ happens could become part of the package.

    The buddy system may important but it comes down to: Do you require a buddy to drive a dangerous 2 ton vehicle? Do you need a partner to run a diesel generator? Point is, the less hands the better. A supervisor may be necessary.


    You know.. perhaps there are financial brackets establish. DIY level, commercial level, national level.. 
    under 5,000, over a million.. 

    The winner will be a ratio of, the cost over electrical output. Alot of hands equals more cost... bigger projects.. bigger costs.. 

    Im betting smaller and more efficient machine will win. like it always does.

    Subject: Lightning Hazard (review and update)
    Lightning is a validated hazard with conductive airborne tethers, since researchers use wires launched by rockets to trigger strikes. Non-conductive tethers are relatively invisible to lightning (more so in humid air, with surface-charges drained away). Dielectric tethers must not absorb water, nor be brined by ocean immersion or salt vapor.

    Premium kitelines are commonly treated with sealants like urethane that prevent water absorption. I am partial to nylon again, finding that water absorption is a highly-controllable variable. In shock-load cases an elastic polymer like (sealed) nylon can out-perform (inherently hydrophobic) HMPE of a higher static strength.

    What will happen if a large lattice array is struck by lightning? Likely only the proximal lightning path will be knocked out, and the rest of the array can continue to function. Once the storm passes, the damaged sections might be hot-swapped. Lightning should therefore only be a nuisance cost.

    FlyGen systems will require close monitoring and landing for lightning conditions, and siting in high-lightning locations like Florida may be unwise. The ITCZ equatorial zone is often a lightning alley. Lightning at sea and in Northern Latitudes is generally low, so the hazard is often far less. In Texas we often feel menaced working out in the field, but on the Pacific NW coast lightning is so rare, a year can pass without even hearing thunder.

    Large-scale kite arrays can in-principle dam and deflect winds and entire weather systems, just as mountains do, including hurricanes. Smaller arrays could early-on steer hurricanes along harmless paths, or disrupt them, but steer the residual tropical rains inland to drought regions.

    Kites on a vast scale are a powerful geoengineering tool. Quasi 1D kite string and 2D kite membrane in our 3D world enables almost magical powers.

    Subject: Persistence Aloft (review)
    Disregard the common misconception that AWES must come down in calm.

    For several years now, the AWES Forum has documented that all AWES architectures, not just LTA, have a natural potential to be sustained aloft indefinitely in calm, by reversed physics. SkyWindPower and Makani can motor in helicopter mode; Ampyx can step-tow; and all the low complexity classes can also step-tow, circle-tow, reverse-pump, and so on. 

    Aerotecture will someday also bank on its altitude. With a low enough sink-rate, lulls of even a few hours can be absorbed and recovered from without fuss. KiteLab Group has validated persistent kite flight by phased circle-towing (see Forum archives).
