Subject: Re: Wing Construction Economics //Re: [AWES] ROI and lifetime
My favorite geometric model for kite farm airspace analysis is the frontal rectangle, just as Betz chose his disc-assumption for HAWTs. The most basic land footprint is a circle inscribed in a real-world real-estate square. Then the wing is considered according to solidity-factor within the rectangle, a number which seems driven by most-probable wind. The wing is presumed to operate in both static and sweep modes to match conditions. We know rigid wings work best at higher velocities, where soft-kites must furl; and soft-wings are best in slow wind, where a rigid wing must sweep desperately, does not always make the turn, but crashes. Safety is the most critical factor.

Therefore, the rather low wind velocities near populations, at altitudes that aviation authorities will allow us (~600m), seems to predict that only soft-kites can rapidly economically scale to the modern load demands of civilization. We happen to be connected to the very heart of soft-kite mastery, from Jalbert's Aerology Lab, to Culp and Lynn, Drachen Org and World Kite Museum. The range of HG to performance sail-plane wing construction will have smaller elite market niches for the foreseeable future, but we look forward to exploring the rigid-wing design space fully. For all we know, the ultimate kite might be a vast billowing canopy made of tiny solid wings (fabric-of-rotors CC+).

Today I am adding tail attachment points to the Peter Lynn 22m2 Pilot-Kites, so they can be tall-killed. Its the first pilot-lifter I ever saw without a tail attachment, but PL, knowing large kites are more stable, was cutting costs to the max (the few remaining features, like UHMPE bridle, load distribution crow-feet, stacking connector and sand-outs, are tops). Because its a soft kite, I will fix it with a random old sewing machine 2KiteSam gave me yesterday (he has dozens of vintage machines). This is "Wing Construction Economics 101", as Dean Jordan himself taught me at KiteShip. I did composites for years, and now hardly need them, given industrial steel on the surface, and pure polymer fiber aloft.

Some highlights from Alastair Rosenschein, former British Airways pilot:

“It’s just like surfing. It’s extraordinary how fast you can go,” 
“You try to sit in the core of the jet where it’s not too turbulent and where you can pick up some free mileage. It’s not unusual to get 100mph tailwinds but they have got more than that,” he said. “This must be a record.”

We seem to have changed topic.
Peter Lynn seemed quite sure (when I met him in Ashburton 4 days ago) that soft kites on their own were not suitable for an AWES.
Mixed lift and gen AWES however he could conceive of.
Just how bad I am at sewing his latest sssl he could never have believed.
Hopefully my results can also be surprisingly good.

Rod,

We have stayed on-topic fairly well since we moved off the Skysails C 640 thread, if you don't count your surprise visit to Peter Lynn Sr. in NZ(!). Fortunately you were uniquely qualified to agree with Peter about "soft kites on their own...not suitable for an AWES", based on our Open-AWE thinking. To review-

Open-AWE has for several years identified the earth's surface as the ultimate rigid medium to synergistically support soft-kite matter. The primordial staked-out playsail is our fundamental model for megascale AWES, and its rigid aspect far exceeds any other known AWES paradigm. When we talk about our soft-kite arches and isodomes as such, we simply tend not to mention the essential rigid ground basis, but its there.

Ironically, all-rigid kiteplanes, like Ampyx and Makani are developing, do not especially exploit ground rigidity by their single anchor units, so they have far less actual structural rigidity to work with, hence their far lower capacity intensity predictions. What scant rigidity they do allow is expensive brittle carbon-fiber composite that must be sustained aloft, and will not greatly scale; rather than dirt-cheap earth structure that stays "grounded" for minimal-mass-aloft, and scales to km or even planetary dimensions.

Please give us a travel account of NZ and HK as soon as you have time...

Subject: Re: Wing Construction Economics //Re: [AWES] ROI and lifetime

Peter Lynn suggested some possibility of high lifetime (14 months on a tree) for soft kite pilot or for kite of low L/D. Soft giant Mothra Arch using earth as spar is both a kite pilot for lift and a separator _ as lattice _ for power kites of higher L/D. In some posts I related to autogyros embedded in soft wing. For these two configurations, soft kite is expected to cover the area of a kite farm, both providing more lift and separating unities making power, avoiding collisions.

So, concerning power kites the debate is open between soft kite of low L/D , and semi-rigid or rigid kite of high L/D.

Subject: Re: Wing Construction Economics //Re: [AWES] ROI and lifetime
At least in real-world kite-sports and ship-kites, and everything in between (like the paraglider that carried a large group of French skydivers), there is no debate over rigid wings of high L/D. Soft kites rule. We see rigid and semi-rigid wings in the form of performance gliders and hang-gliders as fairly flat markets, as paragliding grows by leaps. For AWES, the final driver seems to be scalability, and there is not much question that soft scales more. Osborne's largest ever wing in history, a parafoil, was many times larger than any rigid wing. SkySails has by far the most powerful wing in AWE, and its predictably soft.

Also, many folks have no idea how final the rigid-wing un-economic crash-risk issue is, and how inherent soft-kite safety drives cost down. The fact remains that we can make and fly a 10x larger soft kite, of lower L/D but comparable or superior power to a high L/D rigid wing, but far cheaper and safer. A high-velocity (high L/D) flight specification does not drive AWES design, which is mostly about fixed-station flight (unlike fast commercial air-transport), and also tether-drag limited, and extremely cost sensitive in needing to compete with cheap oil.

Peter Lynn Sr was generous with his time.
He showed me his reconstructed Stirling engines.
He also took me to an irrigation engineering project in his van. The van had suffered a catastrophic head gasket leakage issue whilst towing 35,000 km previously. A local garage had written it off. Radweld (the gunk you put in your coolant) bunged up the holes and the van still hoons down dirt tracks ... getting quieter and smoother every day.
Various other devices were shown to smooth with time.

Here's the thing... His cloth testing machine sucks air through sail fabric... to test it for porosity... and we use doping agents to bung holes...
Any one else think we can evolve this into one process? Suck air and dope vapour into old kites in service to bung and improve performance.

Subject: Re: Wing Construction Economics //Re: [AWES] ROI and lifetime
Yes; we know that zero-porosity and UV resistance can be easily renewed by resizing aged cloth, and that advanced restorants even somewhat repolymerize degraded fibers. Along with occasional cleaning cycles, to flush out abrasive, corrosive, and/or bioactive particles, fabric treatments can greatly extend the useful life of working kites; but the actual savings may be too small to bother with in many cases, where the derated kite is flown without treatments until its ready to recycle. Somebody should study up on kite recycling economics, to further refine wing construction economics. Carbon-fiber and resin composites do not easily recycle like pure polymers.

Thanks for uploading the new file, Joe
I'm a little concerned with downloading files that I know nothing about.
if one downloads enough files, having no idea what is in them, one is bound to download a problem file at some point.
So, having no idea what the file is about, I declined to download it.
It appears to relate to a "Skyhook".
I think it would be good when announcing a file becoming available, to include a brief description of what the file contains and what it pertains to, so people can decide if they want to even look at it.  Also, it would be nice to have a way to just look at some info, maybe a pic or thumbnail, rather than having to download a file, if possible.
Thanks again

Kite Recycling

This topic thread is dedicated to the study of recycling the kite systems including parts of anchor sets, tether sets, and wing sets.


For various reasons materials in a working kite system will no longer serve the kiting intended. Safety thresholds will be met; performance levels will become unsatisfactory; incidents will occur; UV degradation will advance; wear happens. Awareness of the status of parts of an AWES by smart sensors and reporters will feed data to system management. Maintenance schedules will be sharpened toward an effort to have best ROI in AWES. Rates of part replacement will go hand in hand with the economics of recycling involved materials. The total equation for kite recycling has many parameters; the challenge is not simple; in time companies will partly compete on their recycling effectiveness.  


Questions and answers will dance while solutions grow. There will be alternative solutions. All are welcome in this discussion thread.  Start new topics when high focus is wanted for a corner of the larger question.

1. Peter Lynn once noted that burying kites might be one way to take CO2 out of the atmosphere.

2. Nylon climbing rope recycling:  http://www.climbing.com/news/sterling-rope-recycling-program/

3. Hierarchy of purpose? What might not be good for one service might be good for a less strenuous service.  Use a system or part in a secondary purpose.

Excellent suggestion, DougS. Thanks.  Will aim to be more explicit.

The Skyhook item is a jpg file clip of an US Army periodical that illustrated by artist sketch how a powered aircraft could fetch personnel off the ground by using a balloon to altitude whilst hanging a line attached to a human; the aircraft catches the balloon and tether; the person is pulled up in the air; the tether drag and lift operates to lift the human up in the air; the person becomes the wing at the end of the tether. Both the tether and the human shape play to lift the human out circumstance on the ground.   The system is an instance when a human body with clothes become a wing of a kite system. The apparent wind on the tether and human is converted to potential energy.  Then the tether and person could be winched in to the powered aircraft.

Test human reported fairly mild forces in the lift out.

Oh yeah, I've heard of that "skyhook" technique for extracting personnel or cargo from the ground using an airplane that does not need to land, but don't remember the details such as a balloon.  But the gist of it is, since the airplane is traveling at 90 degrees from vertical, the person on the ground does not feel an excessive force when being lifted away from the ground.

Subject: AWES Kite-Matter as Acoustic Metamaterial

The concept of periodic-lattice Metamaterials, with programmable cybernetic properties, has taken hold in Condensed Matter Physics and Smart Materials Engineering. Acoustic metamaterials are an important class of applications that already range from atomic-scale structures to mesoscale seismic protection of large engineered structures. Our phonon-based AWES share the same fundamental physics, and are in fact megascale metamaterial concepts to generate and process acoustic energy from the latent kinetic energy between wind and surface. Its only natural that we can learn a lot from all the other acoustic metamaterial science. We will make our own contributions to the thriving field, but note that its just as critical to know structural engineering scaling barriers as it is to know when such barriers are not limiting, like many tensile cases. Thus, the old hermetic formula, inverted- "as below; so above", may portend that the newborn tech on the lab benchtop will also work as vast kite-matter-

Here is a very helpful introduction to Phononic Crystals, which allow elastic waves to be lensed and mirrored in endless ways, much as optics do for light. As you read, keep in mind that kite-pumping of polymer line is our elastic wave unit, and kite-matter is our effective medium.

We can see that kite farms made of periodic metamaterial (ordered kite-matter)would in fact be megascale phononic crystals (CC+ Open-AWE IP Pool).

Subject: Age of the Sewing Machine
Just as Rod has lately been machine-sewing his own SS power kite, with Peter Lynn himself, I have been struggling to sew Peter Lynn 22m2 Pilot Lifter modifications, with 2KiteSam's help. I started by practicing with a small wind sock made from hallowed scraps of Jalbert's own cloth, from his Aeroology Lab stash, but the beginner's garage-sale machine that 2Kite had provided choked on the multi-layer taffeta stitching needed to finish tail-kill attachment loops on the pilot-lifters. I am switching to my wife's mothballed Singer, but missing an ideal kite-test wind, after days of calm, and tomorrow it rains. This is the real world of slow progress :(

What is this weirdly fateful machine that magically handles a tiny thread like a sailhand or rigger handles rope? Its a mechanical and structural language that defines an entire scaling dimension between finely woven cloth and industrial-scale forces gathered in large ropes. These days membranes and adhesives can also do the job, but the iconic sewing machine, as old as the industrial revolution itself, remains the dominant technology. The Sewing Machine is an icon of Low-Complexity AWE that almost anyone can aspire to. Want to make an AWES from almost nothing? You'll likely need one of these-

Subject: Cheap Oil and AWE R&D
The familiar cycle of oil prices influencing renewable energy research and deployment is in the down phase. Currently crashing oil prices will tend to make R&D funding more scarce. On the other hand, never in history has there been so much tech investment capital available, and carbon credits are poised to damp low oil-price downside. After-all, we did not see much up-effect when oil hit a historic high several years ago. Growth in AWE R&D has been largely insulated from oil price shocks, since AWE smart money mostly plays a long game; but lingering concern is prudent.

A protective biz-strategy against whatever adverse momentum exists is to shift development focus to value-added non-energy-market kite apps; like remote power, communications, recreation, aerotecture, and so forth. As this latest cheap oil phase slowly passes, and green concerns only continue to build, agile AWES developers can pivot back to energy-market focus, without losing a beat. kPower will be slightly repositioning itself as a general kite tech leader, providing safe cheap powerful lift solutions; with AWE as a major client application. Its hoped diversified foraging for new kite-app markets will build ready knowledge for when an urgent societal call for AWE solutions is finally raised, which may be when a new oil-price high marks a historic "tipping point" for large-scale AWE R&D.

Its now clear that TUDelft coordinated an exclusive H2020 AWE funding application. Almost everything about this effort is publicly unknown, and the open-AWE community naturally desires full public disclosure in real-time. Perhaps there are H2020 open records available online.

RolandS, of TUDelft, is Cc:ed in the hope he will choose to shed light on the technical program proposed, for due public input and scientific integrity, or refer us to someone to answer public questions. We also await Roland's response to a request that AWEIA have representation on the AWEC2015 Organizing Committee, just as GuidoL represents AWEC and BHWE interests. Roland is invited to address both AWESCO and AWEIA questions here, issues which are intimately related to his growing leadership role in global AWE R&D, from the TUDelft program Wubbo created and faithfully served (Wubbo Lives!).

See the second interesting video describing a reel-in/out//out/in where two wings or two trains of wings are coupled. So both continuous power and lift are more possible for reeling method.This project looks promising regarding the possibility of maximization of space. Indeed although each wing has a low L/D ratio (allowing also a longer lifetime) but the major part of worked area can be filled. In my opinion this is probably the best existing project in AWE: simplicity, high output by unity of frontal area, bird friend, long lifetime by less strength in fabric, safety, low cost ... Congratulations for this project.

3 quick observations:

1. the use of a pilot kite
2. the absence of crosswind sweeping
3. embedded in the 1st video one can see what appears to be an actual live prototype

"3. embedded in the 1st video one can see what appears to be an actual live prototype"  Keyword: "appears".  Impressive implementation of a simple drag-based concept, (low tech that actually works trumps advanced concepts too difficult to master, right?) but you notice when the camera pans from the generator area, up to where you expect you are going to see the parachutes, the video suddenly transitions to an animation.  (darn!) It pretends to show the parachutes driving the generator, but if you look close, it never actually does show that.  The animations themselves seem weird too - they don't really show all the parachutes working, and the parachutes look to be different sizes.  The world seems to want to build a laddermill but just can't get it together.  I guess Delfts says it was a good idea but 40 years ahead of its time.  That means when I came up with it in the 1970's it was 60 or 70 years ahead of its time.  Meanwhile a laddermill could be built anytime, but apparently we are all just too lazy to even bother to try.  Oh well...

This is a nice case of Low-Complexity AWE, a Varidrogue AWES. Nice to see ongoing progress :) Is Rod still in PRC? If so, he should visit Guandong. The "equilibrium umbrella" is an interesting idea, which seems from empirical testing. The pilot kites are an interesting train of rounded deltas and what looks like a classic Conyne at top. The varidrogue itself is quite nice, and may be suited as a large-array WECS under an arch or in an iso-lattice.

A machine translation of the webpage Pierre linked-

    Combined ladder umbrella altitude wind turbine consists of two parts: air systems and ground systems.
  • Air system consists of one or several acting umbrella, consisting of a number of equilibrium umbrella;

  • Ground systems mainly by generators, winches (drum and reverse rotation of the motor) and universal pulleys;

  • Between umbrella, is connected by a lightweight high-strength cables and winches between acting umbrella.

  • Air system rises to a predetermined starting height, acting umbrella open command is received, the umbrella body open, under the action of the wind, acting umbrella run up and turn through the cable pulling winch drum, (in this case the reverse rotation of the motor is not running, the electromagnetic the clutch is in the disengaged state), rotation of the winch drum through the coupling, the brake / clutch device driven by rotation of the generator rotor, in order to achieve power. Up to a predetermined height or stroke after receiving the closing instructions acting umbrella, the umbrella body is closed at this time greatly reduce wind resistance, while the reverse rotation of the motor starts, the electromagnetic clutch is engaged state, hoist speed reverse, acting through cable pulling umbrella fast Run down; acting umbrella back to the starting height, winch stops, acting umbrella is opened again, begin a new round of increase in acting.

Note that varidrogues are a special class case of partial crosswind operation, in that the cycle of opening and closing is itself crosswind sweep. KiteLab posed this observation several years ago, and it poses interesting theoretic challenges to old dogma about Lift v. Drag., especially with ring-slot and ring canopies.

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

In open-AWE pool we have already iso-dome-net of element lifting trains that pair to pump/drive ground gen via accumulated driven ropes.


The Guangdong element pairs are without the aggregate stability of iso-dome-netting; such absence also will require more land use for separation.

Corrrection: I did build and test a laddermill in 2008, so we are not all too lazy. Most AWE workers really are working hard to be able to share what we got. , Guandong's pumping varidrogue is not an actual laddermill, and its way paranoid to think they intended to deceive anyone by this fairly ordinary AWE video, which deceived no one (like you demoed the yardstick ST prototype on Youtube, with no load connected). Ed was right, it really is a varidrogue prototype shown in the video, and not a product offering. Get used to us constantly sharing partial results without guile, and lets hope we see work from you that can fly as high as Guandong is.

Subject: "inflatable airborne wind energy systems" (I-AWES)
Formal modeling of "Inflatable airborne wind energy systems" is a TUDelft goal, under an EU funded research grant. We do not have many details, but its clear that "I-AWES", based on soft-kites, is a serious category, even if defined only in terms of LEI and (valved) parafoils.

Lets hope this vital research will not neglect comparative study of inflatable AWES in common formats, like Morse-sled and PeterL-style pilot-lifters; and also kytoons, and the most powerful theoretic forms, like isodome AWES, and other GW unit soft-kite concepts, and SS concepts; all are"inflated", in truth.

Lets hope this pioneering EU I-AWES work helps to engineer the utility-scale kite farm as a single capacity-intensive AWES comprised of a single engineered soft-kite inflated unit. CC+

*** I'm talking about a real effort.  Anyone can say they tested something.  Where is the evidence?  Results?  It is not necessarily meaningful to make a half-hearted attempt that shows nothing.
"

We know this. Any of these similar configuration is, to me, a wannabe laddermill, in the sense of the full implementation would be steady-state looping motion.
"

***Oh boy here we go again where you get to psychologically profile everyone - thanks for one more "diagnosis".
" which deceived no one"  I was simply pointing out exactly what the video DID show, and what it did NOT show, for people who may not have watched as closely as I did.  Or are we not allowed to analyze videos and comment on the actual contents now?  Is that a new rule today?  I suppose describing what a video shows makes one a bad person as of this moment.  OK just stick to that.
" (like you demoed the yardstick ST prototype on Youtube, with no load connected)."
*** Yeah and that demo clearly showed the rotors spinning the generator, did not try to substitute animation at a critical moment.
" Ed was right, it really is a varidrogue prototype shown in the video, and not a product offering."
***Who ever said it was a product offering?  Whi ever said Ed "wasn't right" about something?
" Get used to us constantly sharing partial results without guile,"

"and l

Doug,

Sorry to pop your bubble. I rigged and tested the laddermill at the World Kite Museum, and posted reports on the web and on the Forum. You can test it yourself, if you really want. Of course you had to explain that scale-model AWES do not count with you as "real", since that is such a strange unscientific belief. Your yardstick demo was not real either, if my small laddermill was not.

You also need to explain how Guangdong somehow has surpassed your years of unmatched ST hype by merely inserting an obvious graphic to explain a principle. They are sharing real canopy-prototype testing video, and only you cry foul.

Today is the WKM Windless Kite Festival, where more (not "real") conceptual demos are planned (like reverse pumping flight, in past years). Good luck in the real "lazy" AWE world, where one only complains about ongoing work, but does not deliver,

dave

Subject: Today's World Record- Largest Indoor Kite (44m2)
As the Grand Finale of the World Kite Museum's Windless Kite Festival, kPower's two 22m2 Peter Lynn Pilot-Lifters where lashed together, and briefly towed aloft by the kids of the Evidence Kite Team, for a new World's Record (unless a prior invalidating case emerges). Once again, Peter Lynn is handed a Largest Kite World Record (as he already held the outdoor record) :)

How was it done? A lateral tagline was rigged in minutes across all the bridle-points. Three experienced adults held the kite cells open and stepped forward, achieving quick inflation, then released the canopy, to let the kite whiz-kids run with the kite a few meters across the small gym floor. By consensus of the officials, the entire kite had to lift off to be judged a successful flight. The spectators loved it. Videos and photos were taken. Event organizers will pull together all the names and media for publication and AKA documentation.

These same kPower kites, in FAA colors, with reserved N-numbers, had already begun a storied life of arduous outdoor AWES testing, in sessions to last weeks or months, at altitudes as high as 2000ft. Today's fun record was only possible because soft kites are safe to fly in public (at low wind or towing velocity), compared to any other aircraft of comparable wing area (like, say, a business jet).
