Inch-Worm Kited Transportation, Even Directly Into The Wind (IWKT)
Contact kPower, Inc. for commercial application of IWKT: Licencse: CC+ Technology License, kPower, Inc., ~ Joe Faust


This topic thread is dedicated to the disclosure and development (D&D) of IWKT

in many of its embodiments.


We already have tacking transportation of land vehicles and water hulls. And we have such as KitVes where kite energy is stored and used to drive electric boats into any direction. Well IWKT belongs to such broad family but gives special focus to a method that may have niche applications, but is just aside of the tacking and water KitVes.   Let's take a look at IWKT.



IWKT ?   What does it have to do with "inch worms" might be one one's mind. Let's take a look at the inch worm:

Inchworms


Group: AirborneWindEnergy Message: 16319 From: joe_f_90032 Date: 12/6/2014
Subject: Re: Inch-Worm Kited Transportation (IWKT)

Did you get to know inch worms?  Happy fellas and gals, they seem to be; they inch along and reach and reach and reach. They use some energy to move forward. But notice that they use some of the energy to store mass at altitude; they convert some energy into potential energy to be used at later moments. The posture that has the high arch is a stored-energy phase. From that stored-energy phase they open up the head, that is, they take the brakes off the head's hold of the earth and let the potential energy of the high mass in arch to drop the mass, open the arch and move the head and mid section forward in the direction it wants to go. Fun.


Well, IWKT, has a ground vehicle as anchor to a kite system. Set the  brakes on the ground vehicle. Use the kite system AWES to store up energy in the ground-vehicle's battery during the braked parked phase. Once adequate energy is stored in the ground vehicle, then feather the kite-system wing (or bring wings down), take off the brakes, turn on the go-motor and drive directly into the wind or in any direction wanted or do other good works. Once the energy is used, then set the brakes and repeat the cycle. Go, go, go, go, go in IWKT fashion and give thanks to inch worms.


Many embodiments of IWKT will come to mind for those skilled in the arts. And descriptions of those embodiments of IWKT are invited to be posted, discussed, developed, and disclosed fully in this topic thread.  Gain special application rights for inventive applications of IWKT by disclosing novel applications, especially those that improve the lives of people and animals and plants on earth. Also, perform IWKT works on planets beyond earth.  Other works than "transportation" are implied in IWKT; use the stored energy for other works; but the novel IWKT aspect may most reside in the ground movement cycling.  The water-hull cousin seems to be covered by KitVes, in part.  And we have before covered lightly trans-ocean cyclic travel by kite where water parachutes are used as anchors while the air kite works to gain potential energy in various ways followed by feathering or depowering and gathering the water chute while the potential energy is used for flight progress gliding and soaring; such done in cycles can also have travel around the world by kite system. Again, these are aside of the tacking methods.

Grab the big wind energy, store it, and then travel when the wind is in calm.

Notice in the following video how their is a waiting for the big-energy insect;

then the system grabs the energy packet. Then the system uses the energy

later to do good works:

Subject: Re: Choices in R&D
The "reasons" for the Makani Power choice may or may not be fully disclosed. Speculation might be more interesting that simplistic disclosed statements.  A set of kiteboarders and guys of the hulls-pulled by kite arena decided to downselect to the rigid flygen powr-helicopter-up and power-helicopter-down hybrid system.  The choice fancies matters; the complex looks sophisticated. Such choice might attract attention and funds in ways that KISS might no ... until serious flyoff time when the landscape of investment might drastically change. It would be interesting to know that deep actual motivations for the downselect to the hybrid.

Subject: Re: Choices in R&D

It may be  important to appreciate that a simple kite system is a first-order powered aircraft; the wing set of the kite system is powered by the energy of the wind. A wing set of a kite system can use the energy of the wind to stay aloft, to increase or decrease the tension in the involved kite part: the tether set, to increase or decrease the forces in the involved kite-system part: the anchor set. Energy for others may be formatted for good works in the wing set, in the tether set, and in the anchor set.


The choice to put generators and motors aloft will have many reasons for niche uses. SkySails has explored an aloft tether-embedded reaction generator to make electricity for aloft driving of electrical control servos for their towing purposes. Makani and Altaeros and PierreB and Tracy and others have been exploring aloft generators to match constrained purposes. All work to fulfill some defined purpose.  When purposes expand, then flygens may or may not supply resolution.  Makani adds cost phase of power helicoptering for launching and landing; just how much that constrains final purpose space will tell in time or in analysis; the choice won't fit all purposes. Bang for buck relative to purpose will be story yet to unfold.

Subject: Re: Japan's Softbank enters AWE Investment
This topic marks Softbank's debut in AWE investment. The previous Altaeros announcement is the place to comment on the venture side, and this topic discusses the new institutional investment player, and its potential to continue buying into AWE.

We are seeing an ongoing trend for AWE investors to be giant players making diversified portfolio investments, even in high-risk niche markets outside of their core-competences (eg. Google, SABIC). Softbank parleyed a 20M investment in Alibaba into 86G, and flush with profits (including Japan's Yahoo and iPhone markets), seeks to seed more windfalls across many emerging technologies.

We are seeing the AWE goldrush gain traction, with tens-of-millions of current annual investment, and no sign of slowing, nor any limit to growth imminent. Investors are realizing the sector is real, however imperfect the technology. The progress is unstoppable. Softbank's deal marks Japan's national entry as an AWE heavyweight.

Open-AWE is positioning behind the scenes to enter the world AWE investment arena at mid-cap level, but its a process of herding-kittens, of self-sorting merit players from a soured haystack of would-be "wind inventors". Its not clear if Open-AWE can hold together as an emerging movement, as big investors swoop in to make spot picks. Still missing is a major investor seeking to buy-up value across the AWES R&D field. Open-AWE might be that play, if it can come together coherently.

First, classic HPA is what might come to mind when even using the phrase "human-powered aircraft," but that won't suffice for this HPAK topic.  Of course, the classic HPA with pilot onboard could fly via tether towing in various ways where the tension of the towing line is provided by human power; and such tweak will be forming part of this topic; there are several schemes to convert classic HPA to HPAK arrangements.


Second, be ready to have the human in HPAK to be ground-based or aloft-based (either mid-tether-based or wing-based). 


Third, be open to have some HPAK be energy conversion systems for making electricity as well as doing other good works.


The HPAK has human inputting energy to the kite system to aid or effect flight for the system; the flight will be fully free-flying or partly flying and partly not flying; but with part less-than-whole flying, the system still is an aircraft system.  


So, to start:   ==========================================

Perhaps the most popular classic simple recreational kiting where a human uses muscles to resist the wing set by hand holding a kite-system's string seems top be a HPAK.  We go from that to the human facing the task of flying in a lull or in a calm; the human powers through the challenge by one of several methods: pull in the line on a reel or tug-pump the line for pumping energy to the wing or running in some direction to give apparent wind to the wing set.  Each type just mentioned may be explored carefully; consider safety, limits, purposes. Much to explore. Even explore have an aloft electric wind turbine in the wing set; have the human run in calm and end up generating electricity aloft for various uses. Etc. Have fun.  [In no wind use kPower's KiteSat to charge a cell phone aloft using HPAK play.]


Much yet to go toward HPAK.

Note that Makani recently let slip that it has only done about 100hrs of AWE (Hawaii press coverage). The "  thousands of hours of field testing" was never credible, given the short day-sessions and one known encampment.

I was there in 2007 as Makani began its "evolution" from Low-Complexity fabric kites to High-Complexity rigid wings. Joe is right, they never did bother first mastering AWE with fabric kites, so they can't ever show real due-diligence occurred. Instead they hid incompetence and negligence in fashionable secrecy, pretending to be smarter than anyone, but who could prove anything?*

What amazed me was that no one on the founding team had actual aeronautical design experience, so they wishfully overlooked inherent safety-critical design and the grim economics of a high-capital-cost AWES down-select that cannot survive to pay-back (five-years). They were unaware of scaling law barriers that prevent giant rigid aircraft. It was this incompetence, by kids half my age, that motivated me to leave Alameda confidently, without seeking further employment.

Soon, Makani is to test the M600 in Hawaii, and my sad long-standing prediction is that the design will fail spectacularly, if they try to fly many hours (it may not even launch in low wind, if scaling limits dictate). Pierre would then have a clear case to draw conclusions from, rather than reason from a Makani promotional narrative. However, count on the GoogleX culture to chicken out
if they can get just one all-modes flight session and cover-up the lack of future, letting the concept fade from memory in limbo.

Lets hope some journalist figures out how to ask Makani for its MTBCF data, for Pierre to judge from (rather than giving weight to the marketing narrative).


* There are public clues to how smart the Makani founders really were, like their absurd patents.

I favored stationary AWES vs  figure-eight or loop regarding stability, but it is not so obvious. For example a flowform and almost stationary kites need a tail or another device for stability. It is not the same for kites flying fast (for now I put off the question of passive or/and active control).

Pierre,

Your FlyGen is already a "question" (choice) of active-control. To evolve it to passive-control, to relieve the piloting burden, would be a new design direction.* Passive looping is not the only flight pattern KiteLab Ilwaco developed. If passive figure-eight is your flight-mode preference, KiteLab Ilwaco has shown how-


The need for a kite tail is best decided by testing. The test is whether the system flies better with tail, regardless of secondary esthetic objections (some love and some hate tails). For common single-line kites, a tail is added to extend the upper wind-range, and can be omitted in low wind conditions, to reduce weight (a FlowForm flies well without a tail in low wind),

Subject: Re: Carousel Simulation
A nicely realistic power kite simulation; the simulated kite trajectories are naturally rather chaotic, just as you see in real life kite sports, like racing at NABX, Ragnorak, or Kitesurfing World Championships.

Unfortunately for the classic (KiteGen, NTS) Carousel architecture (turret or track-loop), its currently not practical to fly a cloud of single kites reliably, even with world-class athletes. The many unresolved AWES kitemares are grave: launching-and-landing problems, constant tangles, cutaways, line-wraps around cars, lines fouling tracks, etc.. The computational requirement is combinatorically expensive. A small single-unit failure can halt the whole process. The loose-flock multi-kite architecture is topologically unstable. Reliability actually goes down with increasing unit-count (kite-units are handling scale-limited)

Open-AWE thinking is to integrate all the loose kites into a a topologically stable metakite structure by cross-linking everything aloft. Single-unit failures are rendered benign, line-wrap failure-modes eliminated, and the whole becomes an inherently more stable single control thread. A far higher power-factor results, in the same airspace. Early megascale AWE reliability becomes feasible (excepting an XC track so long that everything keeps well-clear).

No doubt someone soon will begin to comparatively simulate competing architectures, and there will surely be a historic fly-off process, where we watch from the Net variant contending prototypes all over the world, in a virtual Manhattan Project. kPower proposes to provide competative Open-AWE solutions to all ventures that build Carousel surface turrets or tracks, to properly optimize the kite platform design.

Good Point Joe (touched on before, if not fully examined); that the harvesting load may ideally be a stabilizing drag feature (ie. a turbine-tail). A design requirement is to balance the kite center-of-mass forward enough. KiteLab Ilwaco has flown turbine-tails in many forms.

We have long noted hodographic spirals (and loops) in our wind columns, but not yet perfected our flying methods to them. Real-time hodographic data will be essential for maximum AWES safety and reliability. Lidar and met-kites are leading options on the high-complexity/low-complexity spectrum. With practice, once can sight along a tall kiteline for a rich picture of the shear field, from very pronounced or subtle twists and bends seen along the line.

Here is a nice tutorial. Note the 160 degree directional variation in the first hodograph, and sharp kinks and loops in later graphs-

I have a stability issue with the standard cheap parafoil lifting kites, PL9M I have been testing. They seem to have a preference for hanging on the left hand side of the wind window. Yesterday in very strong winds, the line was settled at around 10 degree up from the ground.

Instead of retying the bridle every time...
Is there a standard way to improve left right balance?

Will a weighted drogue tied to the 3 points between the trailing edge corners and bridle point help...?  It would pull more on the RHS trailing edge if the kite leans to the LHS... Does this steer a standard parafoil lifter correctly?

Would the deformation of a sliding back line weight be more appropriate than the fixed weight?

Aiming to find out soon with testing.
Cc4.0 NC BY SA...

A standard simple line &  weight balance adapter for training lift parafoils with respect to gravity would make life much easier.

Yes, there is a definite need for a system of networked wind velocity and direction sensors along a kite line. I have been pondering options for local networks (incl. cellular, wifi, fiber-optic, ham data). A mini flygen turbine or solar panel at each node is desirable.

An updated met-kite system is on our to-do list, to be deployed upwind of our kite farms (or used to prospect AWES sites like met-towers do for wind tower farms).

Rod,

Your are likely seeing helical motion in the wind lean your kite. Its often caused by nearby diagonal-to-wind-direction terrain spilling weak vorticity, or changing weather patterns (in which case handedness commonly alternates as weather systems pass. Its possible to trim the kite to helpfully cancel such twist, but you have to keep trimming as the wind changes.

Sometimes kites lean for subtle reasons, like if the fabric weave is not laterally mirror-balanced across the kite (PL is aware of this, but these bargain pilot-lifters are a new design to the Chinese maker, and maybe did not learn all the tricks yet).

Smaller kites tend to need tails more, since the same wind is non-dimensionally stronger for a small kite. Add tail as needed, and even a bit of ballast on the tail.

To confirm your kites were factory balanced, tow them in calm (note that at the upper limit of velocity, symmetry must break, and the kite will loop in one direction or the other),

Not good enough.

I'm am (your are)  well done.

But I still want my kite to break out of it.
I still want my single line kite to be able to fly higher than my launch space is wide.
I still want a single line kite which isn't reliant solely on the wind direction to figure out which way is up...

Hence for a simplest case steering mechanism whose aim is to go as high as possible and stay there, I reckon Left and Right steering has to be given over to gravity.
A sense of vertical to kite bank angle has to impart influence to the kite steering.
That's not a 100% soft kite I know. but it's going to be 100% more reliable.

So what can do that?
a pendulum at the bridle point is too loosely affected by acceleration which will lead to un-damped feedback steering oscillations.
Will the effect of a weight slung underneath on a 3 point bridle be less as the wind strengthens?
Will it be too affected by acceleration (doubt it depending on shape)

I'll make a sketch of what seems too simple to have not been considered before....

Your pendulum would not be very damped as shown (would jangle), unless you use aerodamping or memory polymer that reacts and recovers slowly from chaotic elongation (common plastic coiled keychain lanyards). Also, your pendulum front lines are working against the desired recovery input.

A classic kite is already a damped pendulum, but the problem is when the wind overwhelms the recovery input. The trick is to find a sensitive amplifying mechanism. Two sensitive input channels available are at the kite bridle-point or tail bridle-point. A small pod with a viscous-damped internal pendulum could in principle provide a two-line kite steering recovery effect. Another approach I am currently pondering (having just come back from kiting in gale-warning conditions today) is to locate a vane on the kite line below the kite. The idea is to force the kite into higher-frequency response so that it recovers or loops faster than lock-out at at the edge of the wind window or looping widely into the ground. This needs testing, and the likely problem is if the kite gets into a looping stuck-state, losing altitude with each successive loop.

Lets also keep in mind that a push-turn requires less actuation force than a pull-turn, as we search for passive feedback stabilization methods. I'm leaning toward using the tail V-bridle for both kite-killing and enhanced passive-stabilization, hoping an integrated design concept can be refined.

The balance of forces shown in that simulation video will be way wrong... so the jangle effect will be just as normally experienced by say KAP equipment. The line springs and force detailed are way off realistic. The video was just to convey an idea.

g still = 9.81m/s/s downward in real life.

By aerodamping do you imply a stiff sheet surface to resist upward / downward movement by surface movement through air? I think the risks of edge tripping such a device outweigh the possible advantages.

A classic kite is already a damped pendulum
I've never liked that analogy / model. A kite is not a classic pendulum in that it damps it's own response to the non linear medium it's contained in by deforming to best match it's environment.

I don't think we want a viscous damping of the gravitational sensing feedback. The kite itself is viscously damped. It would be best if the feedback is faster than the kite motion ... thus decreasing movement and rendering the kite stopped at the top.

What we want to tune for is a slow rising kite that accelerates the sensing mass less than gravity does. Thereby the effect of the sensing mass on steering is predominantly governed by the direction of gravity.

Does that mean we start on short lines...?
In the case of an isotropic mesh auto following lift kite... ACE. keep it close to the mesh is what we want.
In the case of a single lifter pay out once launched.....

We want to use this system on a restricted kite which isn't going to be prone to looping violently accelerating it's own sensing faster than gravity corrects it.... This has some tricky implications in a 50mph wind like we have here today... Do you need to launch from directly downwind if sending up a big line all at once to avoid over accelerating?
Does the kite have to be massive to scale to that speed?
Should we launch from the side but have a tag line steering input which decouples once a sufficient height is reached?

Where you say....
Lets also keep in mind that a push-turn requires less actuation force than a pull-turn, as we search for passive feedback stabilization methods.
I can't see how energy expenditure of the recovery of a push (a pull) is any different. You have to have an amount held to be able to release it.

and...
 I'm leaning toward using the tail V-bridle for both kite-killing and enhanced passive-stabilization, hoping an integrated design concept can be refined.

Tail V bridle enhanced passive stabilisation....... That's exactly what I've been describing isn't it?

Oh well at least a bit of weight would help avoid tumbling over backward on our pitch axis as an atmospheric gravity wave breaks.

Rod,

As usual, we must rely on testing to settle which ideas win. The kite really is a pendulum, its not just an analogy (Peter Lynn, etc.). Pendulum Stability is used by many aircraft classes. Its a damped chaotic pendulum, formally; kite loops happen in normal flight, even by kites classed as "stable"..

The KAP comparison is misleading because the normal place to hang a camera is at the harmonic node closest below the kite, rather than hang mass at the kite, which is an antinode (your short-bridle placement also chokes the kite cells). It can be done, but an upper mass like yours will tend to kick around in turbulence ("jangling") unless well damped. Jangling is how the sense of up and down can be lost by too fast a response mass. A slow pendulum response at the kite, or reference to a fast pendulum signal at the KAP node; both tend to decouple turbulence.

These single-line problems are an ideal kindergarden for the monster kite systems to come. Its a well worn learning path where everyone who flies for a few thousand hours, tinkering with many designs and ideas, will arrive at the same summit,

These are not new ideas here. Being in play they need working names and definitions-

A FlyGen Train is a single upward row of small flygens with pilot-lifters at the top. A FlyGen unit needs to be small (~3-5m rotor) to avoid excess mass. Ganging units in a train allows some capacity scaling. 10kw AWES of this type seem workable at ~150m altitude. The FlyGen train concept can be tested with production KiteSats at half-scale. Interesting design aspects include optimally staged conductors, (not done before in AWE), and perfecting rigging and operations. A new AWES trick is that a windbreak at the surface can handily stop the turbines from spinning dangerously as they are launched or retrieved.

A Carousel Boa is a halo of integrated kite units to drive a carousel turret or ring-track more powerfully and reliably. Its cycle is comparable to many single kites on a carousel, but its design is more topologically stable and a simpler control problem. This (soft-kite) boa idea is outwardly similar to the IFO DS (rigid-wing) ring-snake, but in a very different operating regime.
