Subject: Re: Makani on Hardpoint Strain Reliefs
Strain relief design is ancient and well understood. Fokker pretty much perfected the process industrially by testing-to-destruction and beefing up the failure point until it stops failing. New FEA methods produce elegant quasi-biological structure close to theoretic optimal. Makani is futzing with a simplistic design that has not been tested realistically. They patent most promiscuously of any AWE player, without any practical inventive leap evident.

This patent seems above all to indicate a brain-dead R&D program that lost its way, and its painful to witness.

"We also believe that as long as the most efficient design has not been identified, close collaboration and exchange of results will accelerate the technological development and hence be advantageous for all companies for developing their individual commercial systems."

Comments: 


That belief seems to support the reason for our forum here. 

================
The paper has a short view of AWE; that is, the paper only sees electrical production as the end of AWE.   Hence lift and traction and specific mechanical tasks are neglected, etc.   And the paper touts a role for control that seems to me to miss passive control opportunities.

Another current case of kite-yoga resurgence coming to AWES Forum notice. There were many Hippy-Era kite-yoga associations in the old kite magazines, and Indian yogic Vedic culture has ancient kite traditions. Chinese Daoist and Japanese Zen-Shinto traditions also feature kites along yogic dimensions. The "Dancing Kite" itself is the common spirit-object.

The technological kite is built on the magical kite of our ancestors, to paraphrase Sir ArthurC.

Subject: Re: Power-kite on arch-loop testing at Texas AWE Encampment
Today, for the first time, the power-kite flew autonomously in large crosswind sweeps on the arch-loop. The power kite's two lines were rigged into a single loop thru two pulleys on the archline, which freed the  roll-axis, while defining a yaw-stabilizing "bar width". The kite was free to seek a closed flight solution, including a few spontaneous back and forth sweeps and some manual steering. Many self-landing and self-launching cycles were observed, with less stuck states, due to closer detailing. The final step is to rig a passive "pacemaker" input to regulate the sweeping oscillation, and then drive a working load. Thus goes the pleasant "dialing in" of all tuning dimensions of a novel aeronautic platform.

This particular AWES rig brings life to one of Payne's classic schemes, and also owes to to Joe Hadzicki's crosswind cableway buggy [Lang, DF, 2004], but improved in losing the buggy, and the cableway flown high as an arch-loop. It is on track as a promising passive control AWES design free of complex automation. Pictures and video soon.

Yesterday, in blustery high wind, the power-kite on the arch-loop took all kinds of severe turbulence, recovering from upset time and time again. It flew stably most of the time, and developed fast load-motion in bursts, but did not spontaneously pump rhythmically. Occasionally, the bridling snagged on the crude arch-loop knots characteristic of prototype rigs, a failure-mode that goes away in carefully refined production kite designs.

The finding so far is a simple arch-loop tends to damp power-kite self-oscillation, which is good for a stable "parked" state, but an added passive-feedback feature seems necessary, and will be tested next. The practical theory is that a suitable spring-mass oscillation dynamic can be discovered to regulate sustained pumping, just like a pacemaker regulates heartbeats.

What is already clear is that a power-kite likes to fly from a crosswind arch-loop, and promises to deliver steady full power, as specific oscillator design details are next worked out.


On Wednesday, April 26, 2017 11:35 AM, "dave santos santos137@yahoo.com [AirborneWindEnergy]" <AirborneWindEnergy@yahoogroups.com  
Its such a simple AWES rig concept, to set an arch-loop cableway crosswind with a power kite on it. The idea is that a power kite will self-oscillate as is, or by passive-steering feedback forces by tag-lines. As the power-kite dances to-and-fro, it pumps the arch-loop for power harvesting. This is a new experimental space to compare with looping-foils, a closely related "baseline" method.

Yesterday, at East Austin Soccer Club's fields, a first-try arch-loop was rigged with a power-kite and flown in light fitful surface breezes. The power kite was an old Prism Stylus 1.8m2. This sort of test in turbulent air relies on the fact that there are coherent derecho gusts lasting several seconds, to test nominal function, as well as all kinds of odd turbulence, to test stability and robustness. Because top wind velocity was low, no load was put on the arch loop.

All-in-all, it was an encouraging session. Even with intitial guesswork tuning of the geometry, the power kite repeatedly self-launched and landed, with stable flight at the "zero-point" wind velocity, and the predicted beginnings of powerful oscillations in gusts. Marginal wind is a most chaotic kite energy level and there was an occaisonal roll-over of the kite at the surface, that might or might not be a true stuck-state, if waiting does not sort out twist.

Rigging a pilot-kite to elevate the arch loop was tried, but the wind dropped below minumum sustained flight velocity. Its expected that a fully rigged AWES in stronger more consistent winds will load-pump powerfully with good rhythm. Today's developmental session may achieve that milestone.

So here is the picture-link of the May 1st rig in its specific topic thread, giving an intermediate view of the experimental series. It seems like an ideal rigging solution for a passive or active steering of a COTS power kite on a crosswind arch-loop cableway. Thanks to EdS and JoeF for assisting the documentation. Now anyone can directly see how simple this AWES approach is, without the vagueness of a word-picture alone.

For definitive video, higher wind, a more refined rig, and a realistic load are desired

Subject: Simple Star Network Control Synchrony Method for Many-Kixel Arrays
We lately identified identical suspension lines of a basic conical parachute as a star network topology ordering the whole, as an Inverse Boltzmann Distribution. Many kites have this topological organization to varying degrees, like the classic Edo. Star network topologies are a common feature of BEC analogues across many disciplines, where many-units are constrained to act-as-one, under star network control theory. As we develop large crosswind lattice arrays of "kixel" unit-kites in fundamental crystalline plane arrangements, the practical question arises as to how to synchronize all units to produce coherent bulk motions of the AWES "metakite". A crystal plane wants to move coherently, in ideal conditions, but in the real AWES world there is turbulence and many other perturbation sources that create parasitic an-harmonics.

A ready AWES solution is to create a star network of tag-lines, typically upwind, to help the array set planarly, but also to provide each kixel or local kixel group with a synchronizing control channel. A double star-network of control lines, radiating from a common point, has the potential to toggle every kixel in a common tacking/shunting/flapping oscillation, directing the metakite to pump powerfully as a whole. Once again, we see a natural division between crosswind motion structure and windward guy/stay structure that braces. Here we note how windward (or leeward) bridle lines toggled together can create coherent BEC analogues in theoretic AWES metamaterial ("kitematter"). This method avoids undue acoustic-relativity distortions that could otherwise prevent coherent bulk motion of a many-kixel AWES array. 

Current kPower single-kixel experiments (power-kite on arch-loop) are intended to naturally scale up in arrays synchronized by star network control topology. This is a vast design-space to explore, opened up by new understanding of possible kite lattice dynamics.

Nice sample paper covering BEC star-comb topological network analogues, as applicable across many engineering and science disciplines. Students should first master the basics (like phonon-as-boson), if this level of treatment is just too obscure to understand in a kite context. For the more advanced student, note that Debye Temperature applies to our macroscopic kite lattices, in applying this mathematical physics, or one can substitute Planck's Constant's quantum-of-action with our lattice constants-

Subject: Yan's "super turbine" concept and laddermill implications
Noticed this link on a GordonS post on someAWE, of a crosswind-oval plan VAWT scheme, with many wings on a cable-loop. Not much to say new, since this is not an AWES concept, and we discuss airborne versions regularly as "laddermills", but Yan specifically points out a key advantage to flattening VWAT motion for maximized crosswind sweep and minimized upwind/downwind motion. This is especially crucial to flight, to maximize power-to-weight, and non-flattened VWATs are penalized accordingly. Its also proposed that soft-kite structure can be more robust than the sparred contraptions past inventors have envisioned.

We have studied many variations on the laddermill theme, and a key engineering design goal is to secure maximally crosswind motion. Crosswind motion is the basic idea behind Wayne's "Vertical Blind Affair". Earlier semi-vertical laddermills, like Selsam's and Ockels, could not achieve high crosswind motion. Laddermills can be classed as "flapping stacks", of tacking wings in phase-space. Indeed, these laddermill concepts might work best if both sides of the stacked loop just porpoise (flap) to pump up and down in alternation, without the fuss to pass the wings through a loop continuously. In effect, KPS is exploring this operating topology with a single kite on each side, rather than a stack, and kPower is testing "pure" crosswind motion of a single wing on a loop, if not yet a "laddermill" of wings.

Subject: Yan's "super turbine" concept and laddermill implications
Hi All,
The Yan long-oval "super turbine" isn't practical for most locations. It
requires a wind predominantly from only one direction, and its opposite.
Many other inventors have proposed the same thing.
However, Stretch-Kites could benefit from a continuous loop of blades
supported by two end-kites. That option seems worth exploring. Simple
flop-pitching of the blades would suffice.
But the Yan article gave me an idea for a VAWT that, while not a practical
VAWT, should be the most efficient wind turbine.
"Intermeshing Sharp VAWT":
The concept is simple: Use two, counter-rotating Sharp Cycloturbines
(https://www.youtube.com/watch?v=LXUiDx-F6FI )
Suspended them (so they can orient to the wind) side by side and link them
(perhaps with a timing belt) so that they must revolve at the same rpm. Then
move them closer together so that their retreating blades intermesh as much
as possible. That creates a single VAWT where the blades are moving upwind
on both sides of the VAWT. The advancing blades produce much higher thrust
than the retreating blades. So in this case, the swept area of the
retreating blades is mostly eliminated, leaving only the swept area of the
advancing blades. If the Cp of the individual VAWTs is 0.45, the Cp of the
Intermeshing Sharp VAWT should be in the .60's. If the tip speed ratio of
the rotor was 3, the local TSRs of the advancing blades would average 3.5.
Then tilt the intermeshing rotor to the wind to increase the power. The gain
could be as much as 35%. The "equivalent Cp" might be around .80. (The
"equivalent Cp" uses the original swept area when the VAWT is vertical for
calculating the Cp. A vertical VAWT at the edge of a cliff or a tall
building can benefit from an updraft that has the same effect. So the
"equivalent Cp" is a legitimate measure of VAWT performance.)
However, the two rotors would produce more total power if they were close
together, but not intermeshed. If tipped to the wind, they could produce an
equivalent Cp of about 0.60. So the super-efficient Intermeshing Sharp VAWT
is merely another theoretical way to demonstrate that VAWT can be much more
efficient than HAWT.

Subject: Re: AWE-ifying Multirotors
This paper can be classed as student work, worthy as such, but without direct lessons for AWE experts. Its a tough intellectual call where to draw the line between being swamped with second-tier sources (and weak patents), and focusing on the very best research, which is scarce but golden. Are we to refine our gold or dilute it? Testing is the key to refinement, to make AWES judgement sound. Let anyone test AWES multi-rotors rigorously, to see what happens in real comparative fly-offs with other well-tested architectures. Concepts unable to show up in fly-offs are stuck.

PeterS needs good comparative data to prove his logical implication that a VAWT rotor can compete with a HAWT rotor by power-to-weight, for an "energy-aviation" role. Its not very convincing to compare a quasi-2D VAWT array only with a single HAWT rotor, to give the array scaling advantage only to his favored downselect. HAWT rotors can also be arrayed in quasi-2D, with known inherent advantages like higher RPM and/or power for mass-equivalent units, based on decades of wind R&D. The modern HAWT is not dominant due to some conspiracy or bias, but because the VAWT has not proven superior in practice or theory. If the VAWT is competitive, let the VAWT experts prove them so without excuses.

Joe posted some AWEsome papers the other day but I thought a link to the actual project homepage might be helpful:


http://awesome.physik.uni-bonn.de/


Quote from the page:"Our working group concentrates on the development of open source autopilot algorithms for freely available hardware, both in terms of the airframe as in terms of the sensors and control computers. We call our concept "AWEsome", the Airborne Wind Energy Standardized Open-source Model Environment. The goal is to contribute to the open exchange of ideas in this quickly developing field and to make it easier for new groups to start with a freely available functional system."


The team so far has implemented a fully functional system that provides autonomous starts, patterns and manual landing capabilities. Building a ground station controlled by the AWEsome autopilot will be one of their next projects. 


The system is based on very mature hard&software including Pixhawk, Ardupilot and JSBsim


NOTE: I am not affiliated with the the project - the similar name to my project someAWE.org is coincidence :)

A particuar mystery is whether Ampyx has so far demonstrated any auto-launch or auto-land capability, for all the years and millions invested. Are they naively or slyly proposing to master these modes only as they scale up? Its not so much that Ampyx is has done a poor job with what they do show; the concern is that they have established a business culture of concealing their technical gaps while raising millions that would be far better spent in transparent comparative research across all the major architectures.

Neither Ampyx nor Makani ever did comprehensive due-diligence in system-identification before rushing to down-select high-risk high-complexity architectures. Perhaps BEV leadership and funds can impose a fly-off program between the three major AWES architectures that have so far received major funding, Makani, Ampyx, and SkySails, who will all be in pre-revenue desperation (GoogleX may have to dump Makani on some outside investor, as it has done with other turkeys, before a BEV play can be sought).

Barely solvent after its sea trials, with no shipping giants ready to be early adopters, SkySails needs to show they have made the transition to generating electricity on land, while Makani and Ampyx have been driven to sea owing to excessive risk to populations by fast massive kiteplanes. With lower operating speed, SkySails will be hard-pressed to minimize reel-in cycle parasitic losses, and needs a crosswind-only load motion solution. kPower has been working on pure-crosswind rigs with SkySails North Sails NZ ship-kites in mind, but is not quite ready to freeze on a concept design, pending more small-scale experimentation.

Subject: Re: Yan's "super turbine" concept and laddermill implications
Crosswind-cableways can in principle be rotated, as a trade-off. The open question is whether the advantage of crosswind load motion is worth the effort. The answer is more likely yes in places that have more consistent winds, like gap-winds, sea-breezes, trade-winds, etc.

The big question about Sharp Cycloturbines, meshing or not, is where are the prototypes, after decades of claims? Its not enough to claim great things in wind engineering, they should be shown convincingly, given reasonable time. Its time these VAWTS were tested for power-to-weight, to settle their objective AWES promise.

Peter Sharp remarked: 

Hi All,
It's odd that the Kale article on arrays doesn't include VAWT since it's
easier to make arrays using VAWT. For a given shaft length and rotor
diameter, stacked VAWT can achieve a higher power than a Selsam multirotor.
The VAWT stack can be vertical or horizontal. If horizontal, it would need
to orient to the wind. So for land and sea based arrays, VAWT have the
advantage over HAWT. My passive pitching VAWT (Sharp Cycloturbine) has a
special variation where it can operate on its side. The normal variation is
best for vertical stacks. 
However, if used as part of an AWES, a Selsam multirotor seems easier to use
because the angle of the tether approximates a reasonable skew angle needed
for a Selsam multi-rotor.
To see my sketches of Sharp VAWT arrays on land and sea, search for "How
VAWT Could Replace HAWT" (June 27, 2016).
A Sharp VAWT array could be suspended from a pilot kite. It might be lighter
than a single HAWT rotor with the same swept area since it is a 2D structure
that benefits from the square-cube law of scaling.

Subject: Niche AWE: Wind from falling kite systems for AWE
There is a wide realm of AWE niche applications
conceivable using wind from falling masses. 
Some applications already are in the experience of 
humankind as well as some other living creatures.

In a planet's atmosphere have a falling kite system. 
From the falling an apparent wind will be provided. 
During the falling kiting convert the apparent wind
into works of importance. Let the works variously be
over the full spectrum of possibility including the 
production of electricity, but certainly not limited to such. 

This topic thread invites mention and discussion of 
various applications from the conversion of wind
obtained from falling kite systems. 
==========================================

Beginning: 
   It can be noted that in many atmospheres during the fall 
of a working kiting systems, there may be thermal updrafts
and various horizontal-to-planet-surface winds that would
affect the flight of the falling working kite system.  When
such is important in a particular application, the awareness
of the updrafts, downdrafts, gusts, and horizontal winds
in combination with the wind obtained from the falling, 
then sensing, reporting, and control will play roles. 

Preliminary mentions of some known extant systems in this
topic: 
1.  Falling gliding parachutes for personnel and material transport. 
2.  Kiting (ballooning) spiders. 
3.  Kite hang gliders. 
4.  Advertising flags set on arch line between two falling kited anchors. 
5.  FFAWE
6.  

Once some conceptions are put up on the discussion table, 
it might later be discovered in research that one or more of the 
conceptions have some actual extant history.  Good. 
Feel free to dream here. 

========================================
Note: Falling need not end; that is, if an updraft occurs to lift the mass
of the kite system again before meeting the planet's surface, then
more atmospheric kiting time may occur.  Also, meeting the 
planet's surface might also be avoided by using energy converted
from the working AWE process in combination with other energies
to effect a climb vertically for some more falling actions. Perpetual
motion is not suggested; a combination of energies would be needed;
that is, The conversion of wind from the use of the system's own
potential energy would not be enough energy to climb all the way
back to some starting point.

However, consider system FKS (falling kite system) where only the 
energy produced during the falling is routed for use in some climbing
vertical flight.  Fall and convert energy; store the energy until a 
climbing process is wanted; then spend the stored energy for 
some powered climbing flight. Assume no use of thermals or 
other energies, the the powered climbing flight phase would allow
some distinct regain of altitude; that altitude would provide a return
of some of the potential energy that was once known by the kiting system. 
That refreshed potential energy then could be spent in AWE in a falling
phase again. Repeat the cycle until damping losses allow no more 
climbing phases.  Competitions?

The success of these parties seems limited by regional bounds, having in effect shut out a wider world of AWE R&D, with no Italian teams and one French team (gipsa-lab) in HWN500's EU realm, and no non-EU AWE players. Its not too late to correct these gaps, but current leaders seem content to spend lavish funding within a provincial scope, and neglect governance reforms.

AWEIA remains the one worldwide AWE association, but is still picking up from long severe marginalization by the AWEC/BHWE/HWN500 circles, who, since 2010, have dominated AWE conference planning, even including explicit exclusion of AWEIA representation. Ironically, these same EU insiders may have saved AWEIA by secretly killing off AWEC. The call continues for successor nominations to founding AWEIA president, John Oyebanji, who has nobly endured the years of rejection by the newer venture-driven associations. The need for a stakeholder-oriented worldwide association has only grown since AWEIA was founded as the first such effort. Please support AWE by serving any of its associations.

Some observations-

OKB boat design is based on Anne Quemere's proven previous Atlantic crossing kiteboat (image below)

Ozone is the LEI kite provider to OKB, a top name in power kites and paragliders. Rod was hoped to track down Ozone's mysterious Scottish founder, to draw him into AWE, but Ozone is not waiting, since kite-sailing is scaling path to AWE. A boat's free motion makes kites easier than land anchoring, especially in giving up excessive surge energy by downwind motion.

OKB intends to create a kiteboat racing class, which would be a first. Kites have figured in sailboat racing, in some open classes, but mostly as a banned method, including America's Cup, where KiteShip's OL badly spooked the Kiwis, the best racers in the world. SInce then, North Sails NZ somehow became the kitemaker to SkySails, so the Kiwis are on top of the method now, not to mention, Peter Lynn, modern Kiwi kite-sailing pioneer (the Maoris knew kite-sailing as well, as Polynesians).

Broken link ("kiteboot") in prior post corrected in latter post; and here once again-
