Rod,

      For some FlyGen Trains, see that a classic centipede or segmented dragon or train of Eddy wings are fundamentally wind-energy conversion devices; add to some or most of the wing elements, say a tail-electric gen as generator station and stabilizing mechanism and have a "flygen electric train" or "FlyGen Train."  One may have a Sound FlyGen Train that specializes in making sounds at the train cars or segment wings of a train kite system.   One may have a Light FlyGen Train that has the wing segments specializing in generating light from the wind's energy.  Or a flygen train may mix various generator types: electric, sound, light, heat, lift, motion, tasking, etc.

There are many variant versions of Rotor (incl flygens) Trains and Carousel Boas in the Defensive Disclosure drawings. Once again, you might find a new or better concept in trying to imagine an existing one from a foggy semantic description.

Carousel Boas have an interesting spin-wave structure, with key features (like downwind-phase retract) to discover,

Subject: Inverted Boltzmann Distributions in AWES Physics (Negative Absolute
The exotic physics of kite flight hide in plain sight, revealed only by seeing deeply. In the early AWES Forum many paradoxes where noted that lacked explanation in our circle. In particular, UHMPE properties are remarkable, and the superconducting transmission efficiency of common towing-force is worth explaining.

The zig-zag molecules of UHMPE have the thermodynamics of polymer; such that when they are stretched as quantum pendulums their entropy decreases. More energy is entering the molecular system, but order is seen increasing. This is called an Inverted Boltzmann Distribution, and signifies a Negative Absolute Temperature (which is hotter than a merely postive temp, so thermodynamics is not violated). The amazing part is that we can scale our tethers to many km, and most of the carbon atoms are in coherent phased co-related quantum states (macroscale anyons obeying BES).

As we consider our megascale polymer gel AWES models made of 3D latttices of line and membrane it becomes apparent that the AWES latticework begins in a topologically ordered, but geometrically disordered state, laying on the ground. As the Kite Matter pops up into wind and the wind energy in the system increases, its geometric state is increasingly ordered: An Inverted Boltzmann Distribution again emerges, with the consequent theoretical presumption of Negative Absolute Temperature. How cool is that?  :)

Subject: Google-Makani M600 Bridle Collision Risk
Noting that the M600 as shown on the Google-Makani website has an obvious bridle-turbine conflict. With just a small nose-down pitch variation, the left (port) side and center bridle would foul on the turbine rotors, likely causing a crash. Expect to see this problem somehow resolved before the prototype flies, but its not a simple problem. As the Wing-7 configuration scales up, the designers can no longer easily afford the long-proportioned flygen pylons and skids that kept the turbines clear of the bridle. A radical design solution is to redistribute the turbines well clear of bridle interference. Far larger engineering challenges are hidden behind the venture stealth model GoogleX enforces.

Note the M600 spatial conflict here-

That Makani tower keeps getting my attention ...

There will be cyclic bending moments on that tower; if only such bending could be worked into a groundgen ...

The more flygen power mined, the more will be the bending moments on the tower. Out goes much of the "tower" trades versus conventional wind towers, it seems.

Subject: Low-Complexity AWE as job creation engine?
The human role in AWE is an open question bounded by near-total automation for High-Complexity AWE v. millions of labor-intensive (even DIY) Low-Complexity AWE jobs. Two MIT professors covered in the link below claim that high technology has now begun to eliminate far more jobs than are being created, such that vast new sources of employment are needed to offset the trend.

The loss of jobs and the rise of AWE seems to be setting in motion a dramatic scenario where global power-elites develop luxury robotic AWES, from narcissistic desire; while desperate hordes of have-nots struggle to fly dangerously scrappy kite rigs. This is one more classic distopian scifi sub-plot for the AWE Movie. Lets work for a soft-landing in real life, where vast numbers of pro kite-pilots earn a living wage "working" (playing) at the beach-

Subject: Re: Google-Makani M600 Bridle Collision Risk
If the M600 mast is to bend, it should be to help absorb shock-loads (of the kiteplane snubbing up the tether). If it bends to tap power, it directly robs flygen kiteplane performance. The design needs to be a pure flygen, for urgently needed KIS aspects (too little KIS is fatal). A "wafting-lever" as you have dubbed it before, must overcome low load velocity with a high step-up transmission, so costs are higher compared to inherent high load-velocity.

To reference yesterday's post on Inverted Boltzmann Distribution; AWES need to be primed in a higher-energy "taut state" to achieve max efficiency. Making the M600 tower "loose" would work against this.

Subject: Re: Google-Makani M600 Bridle Collision Risk

A theme in many team's description of AWES' advantage over conventional wind regards not having a tower for AWES as conventional wind has towers. The Makani tower is not just a cradle, but a tower that must stand  firm to brace the oblique tether tension.  Consider having a cradle tower that tenses in line with the working production tether.

Subject: Re: Google-Makani M600 Bridle Collision Risk
The M600 cradle must also absorb a hard landing. Of course the designers would do without a tower entirely, if they could see how, and would rightly note, if they could speak freely, that its only a short stub compared to a HAWT tower. The unworkable bridle seems like a more imminent design issue for them, but they are also surely considering what their inherent winch capability can do for their flight modes, and will program accordingly. In particular, and aggressive retract can offload E-VTOL landing, to prevent motor-mode overheating.

This design very unattractive for unpaid engineers outside the stealth bubble to hope to solve piecemeal, esp. if completely different achitectures are far superior. I point out the bridle collision risk more as a cautionary lesson of kids not getting sucked down the hard path of proliferated problems, by having failed to KIS.

We have also learned quite a lot in five years about scaling law limits for AWES, and how to rig better groundgens without large added rigid structures like the PTO levers studied in the early Forum, and since tested by WPI and KiteLab in various configurations.

Subject: Re: * Silo for Helicopterized KitePlane Flygen
AWES anchoring and underground silos can combine synergistically. A prime requirement for an economic (minimal embodied mass-energy costs) megascale anchor is lifecycle inspectability, which a hollow silo could promote. Underground silos are most famous as atomic missile bunkers. Large flygens like the M600 can use bunkers to eliminate onsite personnel risk in the event of a crash. This might be an integrated anchor-silo, in a preferred design.

Also noting that urban cable cars use below-grade moving cables (wire rope in oiled trays). We have also discussed open trenches-foxholes for soft-kite operators to shelter in; plus kite-farm buried grid trunklines, service access, underpasses, and other features below the surface grade. All these features are subject to civil engineering best-practice, like geologic testing and rigorous structural calculations, to specific safety factors.

-----------------

Nomenclature Hint- Rotorcraft or VTOL seems more generic than "Helicoper(ized)". Its not a matter of exact correctness, but helicopter has increasingly come to mean a fairly specific class of VTOL rotorcraft, and so more general terms seem desirable, to not over-constrain the silo concept.

Subject: Butler Ames

U.S. Congressman Butler Ames of Lowell, Massachusetts.

taught formally in 1908, at least, about converting the wind's energy by use of variously shaped airfoils (including variously curved shapes) that flipped leading lead over or  under to trailing edge, that is continuously from angle of attack from 0 degrees to 180 degrees, only to continue such motion to give effort perpendicular to axis of rotation as well as perpendicular to the wind. Flip, flip, flip, flip, ...  He taught carrying loads with the resultant lift. He thus preceded zero-gap S-rotors of Savonius.  The Ames rotatable airfoils would continuous flip or rotate or tumble. He rehearsed many applications for his rotatable airfoils: aircraft, kites, load handling, lifting cars, pushing down, lifting up.  Today we generally see his rotatable airfoils operated as drag-based machines. He did not teach central gap in his airfoils, apparently, as did the later Savonius (circa 1920s).   It is yet to be determined if the later Savonius ever gave nod to Ames.

Any hole or dip in the ground gives the stabilising advantage of high side access and control.
Good AWES design considers the launch, recovery and storage advantage options this affords.
And they are multiple. Not only pertaining to rigid schemes.
But yes massive rigid form arrays can be launched this way in valleys and spin very rapidly.
Really big spinning stuff above that layer will become softer with lower rpm as it grows and can keep distinct drive transfer whilst being attached to the former functioning lifted system.

Subject: Embodied Computation Paradigm for Passive AWE Control
In 2006 Prof. Susan Stepney of York University presented a fine tutorial on embodied computation, linked below. Its a very exciting field for AWE purposes, as it seems to provide a formal basis for Low-Complexity AWE passive-control to out-compete High-Complexity active control. On the AWES Forum, we have gradually matched observed kite physics to the formal embodied sensing/computation/actuation paradigms summarized in Susan's tutorial, point-by-point. Stone-age kite behavior is surprisingly equivalent to quite complex modern active-control systems, and a correct computer-science explanation is of high value. Ordinary toy kites continuously fly a self-computed embodied flight solution "at the edge of chaos".

Extraordinary kite phenomena require extraordinary explanations. What seemed like random dancing and fluttering is making increasing sense. Perhaps even basic (single quibit) quantum computation, based on macroscopic phonon processing, is seen at work (I am lately getting an even split in polling physicists, with the quantum computation folks leaning hard toward kite QM).  Other information-theoretic thermodynamic effects possibly include negative absolute temperature, as the kite in wind reduces its geometric entropy (compared to its ground state) by an inverted Boltzmann distribution. There are many such exotic effects conjectured for kites.

A short-term goal is to validate the kite as a low-cost educational platform for advanced science concepts, for students across all age groups and aptitudes. The long term quest is to put kites to work powering civilization by relatively cheap simple means. Embodied computation for AWES passive control is a key working paradigm-

           Consider having a tether that can suck in canopy wings as well as deploy canopy wings beneath a lifter set of wings. 
That is, fly up a lifter set of wings with a tether set of special design. The special design of the kite-system tether set includes collapsed canopy wings. When wanted: Have the collapsed stored canopy wings deploy to full operating wings. Then when wanted: Have the flying canopy wings be reduced into tight stored format with the result that the tether simply has a region of thickness where the canopy wing is stored, perhaps pulled into a split tether that wraps the canopy wing. Design smart servos to achieve the deployment and storage of the involved wings. A flying system may pulse variations in size, shapes, services, number of operating segment wings, or effective efforts. The growth and reduction processes may occur without full downing of the system.  The wings involved in such growth and reduction processes may be specialized energy-mining cooperatives.  ~ JoeF

Subject: Re: Embodied Computation Paradigm for Passive AWE Control
Brownian motion is at too small a scale to strongly interact with AWES unit scales, and is not wind-like, lacking a general direction. Its kinetic wind energy at the freq. scale of our wings and tethers that counts, and our specific embodied computation methods all work at this scale (like kite tails, airfoil reflex, snowplow-stability, etc.; to compute flight-solutions for turbulence). Effective embodied computation requires a match of temporal and spatial scales between environment and agent, as suggested in the tutorial.

Chaos at any scale must be kept in bounds, or it overwhelms stability at the specific scale. Thus Brownian-motion in excess would cause UHMPE kite fabric and line to melt, but we do not expect ambient temperatures

Subject: Re: * Grow and reduce kite system changes during flight session
The tricky part is that any excess mass aloft, like stored kite area, is parasitic of wind energy. The exception is mass stored aloft whose potential energy is converted to kinetic energy effectively (like the suspended weights of a cuckoo clock). Just as sailors commonly swap sails underway from storage below, hotswapping kites, lines, and payloads from the ground maintains minimal mass aloft. A lightweight rig would greatly lose by carrying a storm rig aloft (and vice-versa, to a lesser degree). This is especially true as AWES are scaled up, and limits are approached.

Conclusion: Its very important to be able to "grow and reduce" a utility-scale AWES rig "during (the) flight session".The design and operational need is to keep as much mass on the ground as possible, but easily hot-swap any part aloft for maintenance, repair, and adaptation to wind and load conditions..

Subject: Re: Embodied Computation Paradigm for Passive AWE Control
JoeF,

The problem with defining AWES flight complexity only in terms of wind-field complexity is that there are multiple sources of complexity present. Kite dynamics are complex even in "simple" wind (smooth steady flow), just as a simple pendulum can go chaotic (the kite is formally hyper-chaotic). Optimal AWES design is very complex to work out, which is why we are still discussing it. Its a bit artificial to suppose the haystack of possible kite designs does not count as a "flight complexity" only because design is a mostly earthbound activity.

A modern definition of kite flight complexity combines wind complexity with kite design complexity. Under the expanded paradigm, its easy to calculate that spider-mill flight is more complex than single kite flight, in the same wind-complexity,

Subject: Re: * Grow and reduce kite system changes during flight session

Good points on the table, DaveS. 

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

Consider flying a lifter set that is a train of wings in a pumping AWES; the reduction of wing elements could be a means of lowering the energy cost in the return phase. Cyclic reduction, cycling flowering.

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

Consider flying train AWES and the decision is to down the system; one means of downing the system could be the reduction process into tether hold of many of the element wings in order to make the downing of the system easier.

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

Consider very-long-tether 100-wing train system; say the system is smart and sees a segment of 10 wings in the train is meeting destructive CAT; the smart system might reduce those 10 wings while letting the other 90 wings stay working. Upon CAT leaving the scene, flower the reduced 10 wings into service again. All remains quiet at the system's anchor.

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

Consider a vast domed multi-wing AWES operating. Have the dome balanced with 500 wing elements in a certain wind W1.  Then have the system see W2 were 400 wing elements would be better for the side tethers to handle. Have smarts to flower and store wing elements to fit the wind being seen. 

    Say wind W3terrible is approaching; have the dome of wing elements reduce exposed area fast to save the whole dome from destruction or uprooting.

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

Consider having an AWES for visual signaling where out or in could code visual signals.

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

Consider an AWES dedicated to entertaining; let the flowering and reduction process be part of the dynamics that entertain.

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

Of course, some of the patented schemes of laddermill variants and serial drag chute AWES constructs employ flowering and reduction of wings on loops to produce drive for works and electric generators; there is a time to flower and a time to reduce for wing elements on some of those described loops.

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

Consider towing up one lifter wing using ground tow, but have the specialized tether loaded with reduced stored wings; then when the one lifter wing is aloft in better winds, trigger the flowering of the tether-stored wings for full-on flight work service.   Low energy would have been used for towing of the pilot lifter wing; much more energy would have been used to tow a full-on flowered train.

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


We are not limited to the briefly described applications of grow-reduce principle; those skilled in the arts will see other uses of the principle.

Subject: Two-Line Pilot-Lifter Advantages
There are multiple technical advantages to reworking the classic single-line kite into an ideal Pilot-Lifter by adding another line, but the practice seems neglected (maybe even since Pocock developed his line-in-a-hollow-braid two-line method for a two-kite power-and-pilot stack). A modern two-line version could provide the following benefits, with a slight increase is fuss compared to the single-line case-


Group: AirborneWindEnergy Message: 16401 From: Rod Read Date: 12/14/2014
Subject: Re: Two-Line Pilot-Lifter Advantages
The limit to usefulness of Two-Line Pilot-lifters appears to be how to connect it to WECS.
WECS can be set on or between both tethers, or in the kite... but that all seems clumsy.
For greater leg separation you gain more lifting surface and more WECS can be flown more steadily.... but turning the control system on the ground becomes a large scale chore.

Utilising Two-Line Pilot-Lifter kites in isotropic mesh networks passively holds the kite steady. And can also allow the benefits of kite steer functions.
Consider a single tether kite as it bridles becomes a multi line kite.
A short distance above a single line kite bridle point ... you can replace the lower lines with a bar or spread frame connector for a two or more line kite. (this kite may in fact be the same as the original 1 line kite of previous isotropic mesh design.
The outer of a small swash-plate / slew ring bearing can allow the lift kite node to lift the net around it... and connect to the two steering input lines.
Whilst the inner bearing ring connects the kite to either or both tilt induced by the steering lines and the mesh ...
or just connects to the kite and allows line differences through the centre to the steering lines of the kite.

Two thin lines to the lift kite can control it's aspect. The net can take the lift. The net WECS lifting can be done in large cell centre average spaces between lift nodes.

This is very like the proposal to have the iso-trpoic net shape influence the kite steering for overall net inflation.
... just with ground determined steering and slightly different net pull down recovery methods.

We found solutions to the multi-line payload problem in the form of pulley whipple-trees, which also work in PTO roles. Am seeing that a prime Pilot-Lifter app is to hold up the LE of an iso- bulk-lift layer. A two-line Pilot with the payload pulleys rigged would be like a tug-boat in flexibility.

We have spotted notes in forum on kite-system tether dynamics. 
And some members are with some special expertise in the tether realm. 
This topic thread welcome further discussion and study. 

But for a proposed start, may I suggest looking into the recent debate
that is occurring mostly in Italian at the KiteGen group, which see.

Do we want to translate carefully and do some duplication of study of notes appearing in KiteGen

Subject: Runaway kPower 22m2 Pilot-Lifter and Amazing Rescue
Yesterday, on the US NW Coast (Long Beach, WA), I was solo testing a new kPower 22m2 Peter Lynn Pilot-Lifter kites in fairly high wind (20mph) on 100ft of 1200lb-test polyester rope. A cold East Wind was blowing out to sea from the dunes where I set up. The kite fought me during inflation, then fired-up violently on launch, and instantly parted its tether, heading swiftly for the surf a thousand feet away, like a large ghost in a hurry. I sprinted vainly after it, but there was no way for me to catch it before it ended up at sea, so I faced entering the foaming surf to struggle desperately with a sandmired waterlogged wing.

Then a car came up swiftly from the South. Just before the kite made it to the water, the car neatly blocked it and locked it under its front wheels. It turned out to be Rae Bonn, fellow kPower test pilot, just back from extended travel. There is probably no one else in town who could have done this kite rescue, and by incredible luck, Rae just happened to be present, with his engine running. Fellow Ilwaco Kitemasters and kPower crew, Jerry and Penny Agree, also showed up as the freak-event transpired, with virtually no one else present; but there we all were, by chance.

The ironic twist is that I had been the one person to run down a  large runaway Peter Lynn Stingray that Rae had lost at a crowded kite festival. In that case, the runaway kite was dragging a large steel spike, and could have ravaged a long swath, if not stopped. I had lorded this rescue over him, but now we were even. Rae figured it was probably my runaway he was chasing, since he has often seen me in wild situations*, over the years. Rae in action-

 

Technical Epilogue- In this runaway case, the tether figure-eight stopper-knot had sheared off under the kite's shock load (a destructive additive combination of recoil energy with end-of-travel impact). In such cases, old-school nylon seems to absorb shock-loads better than advanced low-stretch polymers, but with more snap-back hazard (all 100ft of low-stretch polyester line still snapped back to the anchor).

Runaways are not common, but we must do even better to prevent them. A tricky aspect of test flying is that we want failures to occur, to explore the limits of reliability; so we often fly more negligently than otherwise, to let things happen. Now that our runaway lessons happened (including a Jim Patton runaway kite train), its time to start rigging the new two-line fail-safe ideas.

Subject: Princeton's 2008 AWES used an Austin, Texas, Flywheel

Funny not to notice before, but Princeton's 2008 AWES student project was born in Austin*, which means there is a yet another "lost" local AWE connection to track. Austin is the fastest growing city in the US, and its magic somehow includes more independent DIY AWES projects than anywhere else, and also the oldest continuous kite festival outside of Asia. Gomberg, the kite show master: "...for sheer mass of kites and kiters, nothing beats Austin..."

We (KiteLab Austin, kPower) have figured out how to properly drive these groundgens since 2008, for full power. At least seven AWES flywheels have been made in Austin, perhaps most of the world's total count. Where is the Princeton machine, with its might flywheel, now? We need it for AWEfest, still slowly incubating "Only in Austin"-

Subject: TU Delft will host a 2015 AWE Conference

Dear Friends of Airborne Wind Energy

 

We are happy to announce the next Airborne Wind Energy Conference AWEC 2015: 

The next Airborne Wind Energy Conference will be held at TU Delft /Netherlands on June 15th/16th. Please save the date and spread the news.

 

Further information as well as a “Call for Papers” will be sent to you shortly.


Wind-generated energy is considered to have the greatest potential within “renewable energies.”  The success formula for the future lies in the considerable improvement of the efficiency and availability of wind power plants. To do this, they should be able to harness stronger and especially more consistent winds, which are found virtually everywhere in the world at higher altitudes. This requires wind turbines and Airborne Wind Energy (AWE) technologies like cable-tethered kites and wing systems that access winds at heights above 300 m. The last Airborne Wind Energy Conference took place at Berlin on invitation of the German Airborne Wind Energy Association  www.awec2013.de 

The conference will bring together politicians, companies, institutions, researchers, scientists, investors, students, and all people interested or active in the innovative field of Airborne Wind Energy.

                            Please “Save the Date”.

We’d appreciate to welcome you at TU Delft on June 15th/16th 2015!

 

With kind regards,

On behalf of the organization committee,

Guido Luetsch,

Member of the organization committee AWEC 2015

and President of the German Airborne Wind Energy Association

Subject: Re: TU Delft will host a 2015 AWE Conference
TUDelft in 2015 is a great conference choice. AWEC failed to organize a US conference for 2014, so it badly needs to get back in the game with a strong event. There will be dramatic AWES architectural differences for participants to explore. TUDelft itself has a lot of post-Wubbo explaining to do about its premier AWE program.

Lets hope this AWEC conference finally treats flying AWES demos as a serious activity; with a long lead time for outside teams to plan intense participation. The last conference was run way too secretively, with Guido making unexplained decisions to exclude AWEIA participation, and unfairly favoring one German team, Enerkite, with almost a year lead time for its flight demo. The 2013 flying event was a stage-managed PR "surprise", without maximizing open hands-on engineering exchanges. Only KiteSat also flew, but as a guerrilla demo to a protested AWEC process.

Get ready for a wild conference :)

I found a beautiful real time wind data website that allows the user to see the wind at various altitudes (from surface level to 13.5 km). The link below shows the wind over North America at 2000 ft (600M). You can also "see" temperature, cloud cover, humidity and pressure. It appears to offer a forecast as well. You can input cities around the globe and get weather data and even visuals from webcams if available...

    Subject: Scott-E minimal E-Paramotor
    We keep close tabs on all parafoil technology, finding many overlaps to AWES design and practice. Paramotoring based on small IC engines has been a noisy form of minimal powered-flight for a couple of decades. Advances in batteries and electric motors are recently making E-paramotoring practical. Its clean and quiet; take-offs and landings are slow, with minimal space required. The major E- trade-off, against fuel-based designs, is lower flight-endurance, but this is not restrictive if the task is to quickly catalyze early kite farm launch, or access repair and maintenance work aloft (using canopy relative-work methods to dock). UAS operation is promising. Prices are coming down as capabilities grow.

    Almost anyone will be able to do this. We have already noted DIY flight from a few surface-based solar-panels for charging. Here is one of the latest advances in minimal powered flight-
