Subject: AWESCO on the march
All AWESCO positions are filled and the program is in full swing. This is an impressive elaboration of the popular first-order AWES presumption of reeling units in a kitefarm "brush" topology, without direct reference to other theoretic AWES architectures. Collaboration with Makani seems to have dropped. Apparently neither party is eager to explore comparative architectural research, but are instead doubling-down on refining respective narrow down-selects. At least future AWES architectural vetting will take place between well-developed contenders.

Lets hope for definitive results, like published scaling limits and reliability statistics-

Subject: Re: AWESCO on the march
The quote below Joe pasted from SkySails' AWESCO page does stand in stark logical contradiction to the first-order working-hypothesis of other AWESCO partners; that rigid wings are the favored AWES path. It would be great for AWESCO to resolve this scaling issue within its academic context. In the real world, SkySails has apparently flown more hours, with more power, under more challenging conditions, than all other AWESCO partners combined. The missing bit is how best to harness giant ship kite derivatives to groundgens, with two active players in Austin, Texas, (AWElabs and kPower) focused on that challenge. Looking beyond that, kixels

Subject: Fort Felker doubles-down on Makani's standard pitch, as the news vac
Did we overlook this link from last April? Makani's ten-year saga is a confused blur, but its marketing narrative, at least, is consistent. From April of this year, this Fort cookie-cutter interview offers no real news, as the early AWE world continues to hold its breath awaiting M600's denouement.

Yesterday Ken Conrad, at WSIKF 2016, was able to report, as a recent eyewitness, that an M600 is living outdoors on its perch on Alameda Island (not flying). Its presumed there is more than one M600 prototype unit for the Hawaii testing program. Hawaii media has not reported any imminent M600 flying. No news is not good news in tech R&D.

Subject: Re: Bridles for Stability
In the absence of Makani news, this odd patent reveals more about the thinking within the program than any other source. In this disclosure, Makani is seen increasingly worried about inherent instabilities of its kiteplanes, long predicted here, especially during the delicate hover-to-crosswind-looping-transition. Sensory uncertainty, component failure, and and wind field turbulence are cited problems, but a morass of proposed solutions is not elegant, but involves added degrees-of-freedom (DOF) that add further complexity and mass to the already most-complex and most-massive AWES architecture of any.

Core ideas claimed, of adding an active bridle and providing the horizontal stabilizer with a wider motion range, are really old and obvious, so consider this more of utility-patent narrowly applicable to Makani's design. A variation implied is to actuate the active bridle from within the airframe, rather than a pod possibly acting as a wrecking-ball on the tether during hover or upset. Even other E-VTOL AWES designs, with lifting rotors spread wider more like a quadcopter, probably have nothing to worry about this patent, unless GoogleX ends up burning money on marginal patent wars.

This patent merely fills the conventional tech-venture checklist to file IP. Once again for Makani patents, there does not seem to be any major "inventive leap", nor is deep knowledge of existing kite-art evident (even the term "bridle" is misapplied to each bridle line, rather than the whole bridling). Damon is an interesting figure in Makani, who once claimed to have been hired in less than 60 seconds, but has now become the longest known surviving technical lead in a rocky program that churns through engineers whose names are not publicly acknowledged.

Subject: VIG Wines invests in KiteGen; maybe just a start...
VIG Wines has invested in KiteGen, showing that SABIC's KiteGen investment was not exclusive, and suggesting that KiteGen's current situation somehow requires new investors, perhaps to pay back SABIC, or to fund its risky power wing factory idea (risky, given the unvalidated wing). VIG Wines seems to have plenty of OPM cash to spread across many economic sectors, and is showing active interest in AWE R&D outside of KiteGen's narrow effort.

Subject: Cross Bridling Review and H-Bridled AWES Introduction
Simple bridling is branching string structure to distribute kite loadings and maintain wing shape. Cross-bridling consists of lines to cross-link simple bridle-lines. A common example is cathedral bridling to match a catenary line to a flat wing via many short bridle lines. Power kite Z-bridles incorporate cross-lines fore-and-aft, usually for front lines to support the weight of rear line, to keep the soft-wing TE from being deformed by line-sag.

A H-bridle is a cross-line between left and right tether lines, rather like Z-lines run fore and aft. During WSIKF 2016, kPower flew a 5.5m2 Pansh valved parafoil from its bridle points connected to spread sand anchors. The kite flew stably, but its shape was deformed owing to its bridle being spread apart. An H-bridle was added to pinch together the bridle-points, which corrected the shape, but now the kite wanted to dutch-roll in powerful oscillations.

This variable dynamic stability technique restores to the embedded power-kite some inherent short-line instability in a controllable way, independent of altitude. In effect, the H-bridle creates a new arch loadpath as an elevated surface to host short-line power-kite oscillations. The new H-bridle enabled passive pumping AWES mode is readily tuned to conditions.

Subject: Latest Rev Kite adds new flight modes
Even as Joe Hadzicki's old Revolution Kite utility patent expires, and imitators proliferate, he has reset the design bar higher, with new patented features in his Revolution Reflex.

JoeH demoed the Reflex for me on Sunday at WSIKF, while we caught up on AWE talk*. His inventive leap within the new wing is reversible wing dihedral-anhedral action. An old Rev has anhedral bowing under tension, but is flat during slack-tethers state. The new kite in slack bends back into a dihedral state and becomes a stable glider. In wind too low to fly a normal Rev, Joe was able to pop up the Reflex and quasi-step-tow pump it in sustained flight. It had a fine high L/D stable glide between pumps.

While there are single-line and dual-line deltas and glider kites that also do this, the Rev has an unmatched ability to fly backwards and sideways. kPower is evaluating a Rev variant to carry up an attach a kill-line to a working kite. This worked before for KiteLab Ilwaco, but only by moving around on the ground for kite position. A Rev-based version should allow easier docking of kill-lines by kite steering alone. Perfected kill-line docking will allow large AWES kites not to have to carry kill-lines all of the time, as is current best-practice (Open-AWE_IP-Cloud).

------------------
* To be reported as a separate topic. Joe's formal involvement in AWE dates to [Lang, DF, 2004] and he has been in active contact with many key folks ever since.

We honor Pocock, Etzler, and even ancient inventors for the "real innovation" of the concept of harnessing kite energy systematically, not to mention Payne, Loyd, Roeseler, Goela, Ockels, and so on, all prior innovators.

Thanks JoeF for pointing out "KiteGen Venture" is spelled singular.

Note that there is a loose coalition in AWE circles favoring comprehensive coordinated R&D to move forward, but also many players still hoping to tap into the new funding as isolated private ventures. What is needed is a mix of both R&D models leading to a fly-off process (including scoring matrices and integrated simulations) to reveal best-of-class AWES solutions.

A lot of money has been poured in the AWE field, as well as in the hot nuclear fusion program, without important visible results up to now, in both fields. Money are important, of course, but not fundamental. I think that the nuclear fusion research suffers of the lack of adequate theoretical bases, whereas the AWE technological development is slowed down or blocked by the attitude of people.

"We Were All in it Together" said Homer Ahr in this video, when he reminds of the Apollo program development and of the eroic phases of the Apollo 13 rescue. That short clip is taken from "IBM Centennial Film" by Errol Morris and Philip Glass, the best composer as ever.

Subject: Improved Power-Kite PTO Design
One of the best innovations of Open-AWE was to figure out how to do direct mechanical work with a COTS power kite by adding a PTO (power take-off) consisting of a pulley-based Whipple-tree/lazy-jack force equalizer that filtered control inputs from work output. In small original versions, the pulley-tree was airborne, but as these PTOs were scaled up by kPower, the growing mass of the pulleys and thickened (super-duty) line sections began to cause problems.

The solution is to branch a PTO line from every multi-line and bring them to the ground to a multi- standup-block, and behind that multi-pulley locate the PTO pulley tree that combines the lines to one pumping line. Furthermore, the pumping output line can be routed into buildings or down to a water source to work well isolated from the kite's wildness. These two refinements greatly extend the utility of the early power kite PTO method.

kPower will refine the new design by driving a water pump located at a lower reservoir to irrigate higher up by hosing. Previous experiments validated PTO irrigation by filling a dangling bucket from a pool and pouring out the water anywhere within the kite's scope, which is still a promising method for fire-fighting or spot irrigation.

Subject: Kite Overflight AWES failure-mode
A kite overflight state occurs when a kite overflies its zenith/anchor-point and moves dangerously upwind. An overflown kite can easily lose tether tension and crash, or snub-up its slack tether violently in recovering downwind.

The risk of overflight is confined to high L/D kites and kiteplanes and is especially worrisome for high-velocity high-mass kiteplanes during short-tether phases. Thanks to Ozone Paragliders for the observation that its SS wing is far less at risk for overflight, compared to conventional parafoils, due to less fabric-mass and contained-airmass. Kite overflight failure-mode risk is greatest for rigid-wing AWES designs, but this particular AWES failure-mode has mostly been overlooked by theory, but is surely being faced in rigid-wing AWES testing.

Subject: Energetic positive attitudes and important visible AWE results

The energetic and positive attitudes of many AWE R&D workers has brought a steady stream of important visible AWE results. And more is coming! Spectacular will be a handy descriptor ultimately.  Hats off to those who have been showing their AWE tech to the world through the Internet and field trials. Keep up the fertile work! Energy kites doing practical works is on a march that is gaining momentum. Evidence in part for the positive progress can be found in our over 20,000 messages in this forum, which is just one corner of the energy-kite realm. Hard wing products keep advancing; patent disclosures continue; comparative fly-offs shows signs of becoming more robust. Teams are sharpening their focus. Hopefully investors are becoming wiser. Competition in various branches of AWE continues to bare distinctions that may be used by creative analysts. Materials for wings, tethers, and anchor systems continue to amaze. The body of concepts for potential mega-AWES continues to grow. AWE has steadily increasingly impinged text in governmental circles. Exploration among potential paths to effective work done by energy kite systems continues. Learning from experiments has been building an ever growing AWE tech and safety sphere that will be available to support the growing participation. Newcomers in AWE keep arriving; those who came and went contributed lessons that may help the active AWE realm.  Congratulations to the AWE world for being!

Subject: Re: Kite Overflight AWES failure-mode
Hargrave is often considered the first modern kite scientist, but kite science has advanced over the years to better explain kite behavior, like kite flight at 110 deg, beyond zenith. The current physics interpretation is that a kite in idealized horizontal wind cannot even sustain flight right at zenith, but must fly at some angle <90 deg. 

Several possibilities exist to explain Hargrave's reported kite flight at 110 deg- Perhaps the wind was not fully horizontal, but rising upwards, like onshore wind encountering a sloping shore, and/or the kite was surging forward momentarily by inertial momentum owing to its mass and the acceleration provided by a gust, and/or perhaps the kite glided upwind in lulls, and/or perhaps all these effects occurred in dynamic combinations.

Hargrave's "trapeze" solution was characteristically inventive but primitive. The arch topology is both suggestive but perhaps irrelevant; maybe beneficially damping and shifting the dutch-roll harmonics of the kite to a higher frequency. The added mass of the bar would have interacted with the kite's overflight, tending to damp overflight surge. A certain fact is that Hargrave's kites tended to have more mass to area and higher wing loading than more modern kite designs and materials of the same scale, in similar wind.

Mario,

Its regrettable that you were not able to keep KiteGen and WOW in harmony. You were caught in the middle of bitter personal  politics and greedy venture interests that lacked the aeronautical professionalism you uniquely represented. A similar insider process in the US ruined Makani and AWEC's golden chance to lead a global AWE effort, and the pattern has been much the same in the Northern EU circles with players like Ampyx. By unprofessional neglect, all these AWES platforms, for the many millions invested, are woefully non-compliant with aviation insurance and regulatory safety-reliability standards.

We lost our unifying aerospace-based leader when Wubbo died, but time is moving on and emerging investment conditions (detailed in this topic) have never been better in AWE to finally put together a comprehensive research program, with aviation R&D experience like yours finally driving solid progress. Italian AWE prospects seem increasingly to converge on L'aeroporto di Capannori, on a solid foundation of aviation culture. Please join them in developing major new AWE research, in a growing global collaboration network of the best players.

A lot of money has been poured in the AWE field, as well as in the hot nuclear fusion program, without important visible results up to now, in both fields. Money are important, of course, but not fundamental. I think that the nuclear fusion research suffers of the lack of adequate theoretical bases, whereas the AWE technological development is slowed down or blocked by the attitude of people.

"We Were All in it Together" said Homer Ahr in this video, when he reminds of the Apollo program development and of the eroic phases of the Apollo 13 rescue. That short clip is taken from "IBM Centennial Film" by Errol Morris and Philip Glass, the best composer as ever.

Subject: Peter A. Sharp. Sharp Cyclo-Kite and TCAT
---------- Forwarded message ----------
From: Peter A. Sharp <sharpencil@sbcglobal.net know about my new kind of kite. You can see videos by searching for "Sharp
Cyclo-Kite". It's a cross between a vertical axis windmill and a two-line
kite. It flies in horizontal or vertical circles. When it flies in vertical
circles, it functions as a kite that can fly upwind of, and above, its
anchor points during part of its orbit. When it flies in horizontal circles,
it typically functions as a vertical axis windmill, specifically a "" (search online). But a vertical orbit can also be used to create a
windmill. The blade is typically suspended on thin shock cords, but ordinary
kite line will work too. The blade doesn't stall because it is controlled by
a centrifugal spring that opposes the pitching force acting on the blade. As
the speed of the kite increases, the orbit diameter increases, so the rpm
remains at roughly 60 rpm, at least for models. The Bird Windmill is
probably the cheapest possible wind pump by a wide margin. The blade is used
to create an unbalanced, cyclic pulling force to operate a piston pump. A
rotary pump can be driven directly by the blade as well. And I have a new
way to generate electricity by connecting the blade to what I call a
"twist-cord-accumulator/ transmission", or "TCAT". It spins the generator
intermittently at a high rpm, so batteries can be charged during low-wind
conditions. Please let me know if you have any questions.
Thanks for your attention to my information,
Peter Allen Sharp
PS: I have additional kinds of kites, but I'll wait to see if you are
interested in the Sharp Cyclo-Kite.

The horizontal Cyclo-Kite is an apparently an independent invention of JoeF's Tumbling-Wing DS AWES concept that kPower prototyped in a remarkably similar form.

Peter Sharp is yet another talented developer working in AWE. We are seeing a healthy trend for multiple practitioners in all the contending AWES architectures developing prototypes to a state of readiness for the looming grand fly-off phase of AWE R&D.

Subject: Re: Bird Windmill, thin skin, streamlined I-blade
The profile of Peter Sharp evident from the start is of a cleverly inventive self-sufficient wind-device developer who is conquering the mountain-sized AWE challenge by methodical baby-steps. His prototyping style is focused on key working principles without regard for conventional esthetics. That he had already made the Drachen Foundation's radar is further evidence of Sharp's specialized merit from the kite expert perspective. Even most "top" AWE R&D teams lack these fundamental virtues.

UMaine (LeBreque (Sp?)) and KiteLab Group (JoeF, me, etc.) have also independently worked the design space of pumping looping wings. As a group, we have explored configurations in all three possible axial orientations. At a minimum, two of the orientations match popular AWES cycles with upwind/downwind phases*, with special potential advantages, like DSing in a strong wind gradient, or theoretic pairings in turbine fields after [Dabiri et al]. The third axial orientation, along the wind axis, known as the "Looping-Foil", has fully crosswind motion. Besides simple cheap light powerful passive loopers, there are tacker wings that self-tack across the wind like sailboats. 

The next big design challenge is to cross-link these designs in airborne lattices that pump coherently, showing the way to scale up from single units to vast arrays of many units. Sharp's claim that this is the first kite to inherently travel upwind of its anchor is tricky. For example, Cyclo-Kite/Bird-Windmill operation presupposes an added lift basis. If added lift is from terrain or towers, his claim works, but if the lift comes from lifter-kites, then the anchor-points would likely be upwind of a practical wing orbit.

------
