Here is SkySails page on its 100kW working prototype. Yes, it works by reeling, but kPower/kFarm has tested power kites to also drive electrical power-arches like Payne USP 3987987. Anyone knowledgeable about power kites can see these are quite workable. Reeling is a stepping stone configuration like biplanes were in powered flight.

"Lighting LED's " were used only to show the variations of power, using tiny propeller and generator. 
These variations can sound more by using larger propeller and generator like on https://www.youtube.com/watch?v=_rLbvSATEbg .
The kite I used is 1.5 m². A power kite with L/D ratio of 4 generates about 1 kW/m² with a wind speed of 10 m/s, using flygen method or during reel-out phase.

DS is not properly defined by PeterS as "the principle of blocking most of the wind from reaching the bottom half of a vertical orbit (or the equivalent for tilted orbits)"

No wonder PeterS doesn't see DS effect in its varied forms like JoeF and I. DS is a pure gradient effect, whether or not "blocking" creates the gradient, or any other cause. He does not even mention inertial mass as a critical DS condition.




 

JoeF,

Yes, quadrant 1 for the Cyclo-Kite begins at the bottom of the orbit where the blade starts to climb.

No, DS has nothing to do with the Cyclo-Kite. DS works on the principle of blocking most of the wind from reaching the bottom half of a vertical orbit (or the equivalent for tilted orbits) of a DS glider In contrast, blocking the wind from the bottom half of the orbit of a Cyclo-Kite would make it stop orbiting because it relies on wind acting on the whole orbit, and especially on the bottom part.

New descriptions of a phenomena are always welcome as long as they are clear and complete with respect to the details of the physics involved. It’s also fine to take guesses about what’s going on as long as the guesses are presented as such, or as questions, and are not presented as “obvious” facts which require no evidence.

As an amateur inventor and theorist for more than 60 years, I am acutely aware of how important it is to pay attention to anything slightly out of the ordinary, whether it’s a concept or a physical phenomenon. I am equally aware how important it is to be skeptical about, and question, one’s own assumptions and other people’s assumptions. When someone suggests a new road of inquiry, what I want to see is them being duly skeptical about what they are saying. That is because it is easy to generate new ideas if one does not require one’s self to test and verify those ideas – either logically or physically – by presenting both supporting and contradicting evidence. A person who presents a new idea or a new perspective has the responsibility to do the analysis of it themselves, and not expect others to do it for them. But most people are inadequately skeptical (lazy) when it comes to their own ideas. That is often because they seek status rather than scientific truth. Such people may not be concerned about wasting other people’s time because they assume that their ideas are important contributions (because they believe that they themselves are important).

From the power curves of Cyclo-kite, I'd place sudden climb in power in Quadrant 1, approximate at 5 or so degrees into Quadrant 1 assuming the wing is flying windward in Quadrant 1.  So, I may differ from DaveS as to the position of the "ballistic" event. . The cause or causes of he sudden climb is interesting; if multiple causes, then what are they? Does DS play a part in the sudden rise in power? 

 

When differences in perspective may be occurring, thee may be need to clarify matters. To block the clarification process abruptly may be disturbing. Not recognizing flows of unrecognized distinct perspectives is muddy, I'd say; to work things out would be a clarification process away from that muddiness.   The effort to get "on the same page" or same frame may be a challenging process with a hope of good rewards. Bowing to one dominant perspective risks remaining in mud unless that dominant perspective is error free.  

 

A tiny insight might open up an effective new branch of understanding.  A tiny break in a dam might grow to bring on a huge breakthrough. The effort to find radium was a long haul. Wrestling may be positively respected as exercise and a means to clarify strengths and weaknesses.  

 

Sorting out differences of understanding may be seen as a positively helpful garden of grace. Strengthen one another.  Not just tolerate or discard, but aim to really know the other's perspective; and then maybe persuade or adjust or form some tertiary enriched new common perspective on which to build next matters. What may seem irrelevant on a matter might end up being relevant or might end up being relevant to some other matter in the AWE realm. 

 

We each need not face every question or matter.

Subject: Wikipedia on Dynamic Soaring
WP, JoeF, and I simply do not define DS as PeterS chooses. No wonder he denies DS effect applies in his CycloKite beach demo, with a predicatable DS boost in gradient that that the WP animation shows.

Exhibit A-

"In his 1975 book Streckensegelflug (published in English in 1978 as Cross-Country Soaring by the Soaring Society of America), Helmut Reichmann describes a flight made by Ingo Renner in a Glasflügel H-301 Libelle glider over Tocumwal in Australia on 24 October 1974. On that day there was no wind at the surface, but above an inversion at 300 metres there was a strong wind of about 70 km/h (40 knots). Renner took a tow up to about 350 m from where he dived steeply downwind until he entered the still air; he then pulled a 180-degree turn (with high g) and climbed back up again. On passing through the inversion he re-encountered the 70 km/h wind, this time as a head-wind. The additional air-speed that this provided enabled him to recover his original height. By repeating this maneuver he successfully maintained his height for around 20 minutes without the existence of ascending air, although he was drifting rapidly downwind. In later flights in a Pik 20 sailplane, he refined the technique so that he was able to eliminate the downwind drift and even make headway into the wind."

https://en.wikipedia.org/wiki/Dynamic_soaring :"Dynamic soaring is a flying technique used to gain energy by repeatedly crossing the boundary between air masses of different velocity. Such zones of wind gradient are generally found close to obstacles and close to the surface..." 
This definition contains what PeterS wrote, by mentioning "obstacles". Moreover PeterS' main statement is not about DS but is about the Cyclo-Kite as the discussed topic, and is: "No, DS has nothing to do with the Cyclo-Kite." 

So PeterS is right from A to Z. And DaveS is wrong from A to Z about PeterS' main statement.

Pierre, yes he only mentioned "blocking", and we all agree that works, but his beach wind was not blocked, it was just normal surface gradient. 

Can't you see the DS effect?

Pierre, we all misunderstood that PeterS thought DS only happens in "obstacle" mode, including yourself. But now our "persistent understanding" is resolved.

It was factual to mention a DS boost when operating this device in a normal surface gradient. How could we know PeterS did not know this major DS mode until we slowly worked it out of him? We succeeded in clearing the confusion, as hoped.

Correction: ""Persistent MISunderstanding" is resolved"

There is also a nice elastic damp and boost effect from the flexing poles, where the bottom of the loop stores energy in the poles then released toward the top of loop. Kite suspension does similar elastic boost.

Very cool. More vintage wind art from Culp's legendary AYRS circle. 

Here we see ancestral DNA of Brasington's Ninja Turbine, which tested best as a small HAWT rotor of all kite-store rotors, and was adopted for kPower's KiteSat AWES, as a cell phone charger. Upton's fine "claw" design showed kites again suggesting fabric blades might comprise cheaper safer HAWTs. For airborne performance, where weight is critical, fabric turbines are hard to beat.

Fabric blades may be the key to scaling HAWTs beyond what rigid blades can do, but first rigid limits my have to be painfully proven in over-scaling rigid blades by some major wind player like Vestas or GE.

Thoughts on large fabric rotors, after Upton-

They don't compete right now, but that has usually been true of rigid blades, and there can be grand back and forth and leapfrog cycles in technology. To compete fabric blades must do something different and better than fine rigid blades. 

For example, a tube spar at the root could blend into a fine rigid blade tip for the high-speed outer part of a rotor disc. The inner disc that turns slowly could be a "cheap" fabric sail, perhaps with the capability to completely furl for storms, without feathering gearing.

Another case might be locations where birds and bats are strictly protected. Slow fabric blades in high solidity rotors with gearboxes might prove the only way to do wind and not kill, like at Altamont Pass. In Texas, capacity is lost when radar detection of birds or bats shuts down wind production.

Will Newer Wind Turbines Mean Fewer Bird Deaths?

Fabric might also be the cheapest capital investment for poor populations and cheapest replacement for aging blades.

No one endorses fabric blades; we certainly are not selling them to anyone, but study fabric and rigid blades as they may come and go for many reasons, and love both kinds of fine wings.

Wow, nice pioneering remote supervisory control in AWE. Not every great team just works on power and automation. There are many hot specialties to develop.

This UFSC video was new to us, but its *two* years old, so we can hope for considerable further progress we have not seen, although student projects also often end if they move on and no one follows up.

With so many students and faculty, it looks like a stable research program, well able to weather turnover. A top player, if not recognized as such. Some rough edges; watch them melt away.

These are potentially the most disruptive sort of players in AWE. They see more than are seen, and can agilely down-select to the AWES fast-lane, while most premature major players mire in the side tracks. 

Of course they use power kites, lacking the large budgets of hot kiteplane US and EU players, but intending to win anyway.

    Subject: Re: Active Lift Turbine VAWT

     

    Hi Pierre,

    I think the best way to understand the ALT is to first grasp the basic principle before trying to understand how the ALT Version 3 works to implement that principle.

    The basic principle is that pressure can be converted into energy, with almost no movement required. For example, if we press on a Piezo-electric cell, it will generate a pulse of electricity. So we know that pressure alone, without very little movement, can be converted into energy. So work is done. And power is produced.

    Then consider a VAWT blade with pizo cells located between both sides of it and the supporting structure at the end of the blade’s support arm. When the VAWT blade revolves, that will cause pressure fluctuations in the pizo cells. So they will generate a small amount of electricity in pulses.

    That means that the pressure on the blades of a VAWT can be used to generate power. That power is in addition to the normal power of the VAWT. It is an additional source of energy.

    So if you accept the explanation so far, then it is clear that pressure on the blades of a VAWT can generate extra energy. The name given to that extra energy in the case of a VAWT is “Active Lift”. So it is clear that Active Lift is a valid technique for increasing the power of a VAWT.

    The next step is to understand how the ALT uses Active Lift in the form of a mechanical motion with substantial movement to generate additional torque and power. But that is much more difficult to understand than the use of pizo-cells to create Active Lift.

    Consequently, to argue against the reality of Active Lift, one must show why pizo-cells on a VAWT, as I described, cannot produce additional power.

    So, pizo involves movement (the pressure effects some movement in the material). 
    Suppose infinitely rigid base material; then pressure would not generate via pizo. 
    In blade was infinitely rigid, then perhaps idealized aerodynamics would result; 
    then Betz could be approached more closely.  No free lunch from pizo for going past Betz. 
    Yes, if not infinity rigid, then pizo opportunity sustains for going a bit beyond the imperfect blade set with pizos.

    PeterS angrily insisted DS effect was not a boost factor in his CycloKite Beach Demo, but the WP article shows how DS must apply to CycloKite motion in common surface wind gradients. 

    PeterS defined DS in this context as a "blocking" (WP "obstacle") mode. Wikipedia notes, "different flight patterns can be employed in dynamic soaring", and details the original DS glider history in non-obstacle mode. The CycloKite's wind had no obstacle to create that well-known DS mode, and other DS mode was identified.

    We are experts in DS in AWE, with multiple glider champions and pioneers. We made the mistake of thinking PeterS was using the same definition of DS. Pierre didn't know PeterS's DS assmptions either. 

    Pierre is slow to admit Wikipedia-defined DS boost effect was a reasonable assumption for PeterS' beach demo. I know DS effect applies whenever a wing with momentum flies thru a wind gradient. It has to, under physical law. Its also true the CycloKite can fly without gradient boost, just as PeterS insists.

    PeterS made similar angry objections to "ballistic" in any trajectory but ideal-parabolic, but WP rightly informs, "elementary equations of ballistics neglect nearly every factor " of real-world trajectories like DS soaring. 

    As a community, we are masters of real-world DS. Centuries-old elementary equations are not enough to formalize our complex trajectories. As we update DS science here, we'll define a host of DS trajectories we have noticed in recent years. Its the DS Zoo.

    Toward updating DS Aeronautical Science, here's a starting list of known DS modes-

       Renner DS Pattern: The classic upwind loop in LLJ/inversion gradient that Wikipedia uses in its basic animation.

       Albatross DS Pattern: The idealized pattern attributed to albatrosses and characteristic flight solutions seen in video data.

      Speed-Record DS Pattern: An obstacle-based mode that RC pilots are flying at nearly 1000kmhr from mountain ridges.

      Vorticial DS Patterns: Vorticity is a strong source of wind gradients. This is a class of flight patterns in highly curved gradient fields.

      Jet DS Patterns: Jets are derecho gradients. LLJs are just one of many kinds of jets, but are common in lower AWE airspace.

      Cyclokite DS Pattern: Low swooping at the surface, where wind is slowest. Not a distinct mode; the limit case of the Renner Pattern.

    Piezo must run at high frequencies to be efficient by power-to-weight, like at the frequencies of piezo beepers or tweeters. Kites operate at too low a frequency to drive piezo at more than a weak trickle.

    Hi Peter,

    About your message 26573,


    I agree at least the first part of your message, and above all “so we know that pressure alone, without very little movement, can be converted into energy. “. Indeed some applications could be found for AWES.

    In the other hand I am not sure "That power is in addition to the normal power of the VAWT." as you wrote, and as the Active Lift Turbine concept suggests. By a French expression "we cannot have the butter and the money of the butter", in English language "we can’t have our cake and eat it".

    An example: if we add a reel-out component (even with little movement) to a FlygenKite or Makani wing, it will not generate more power because the adding use of the active lift will be compensated by the loss of the torque that works the turbines aloft.

    It looks to be the same for the Active Lift VAWT. More lift use = less torque, even with little movement. Perhaps there is a problem with the third law of Newton, action reaction, considering the wind as the first body, and the turbine as the second body. But it is only my temporary opinion.

    Sebastian Gros is ideally placed to assess controversial computer science dimensions to AWE, like why AI can't just "solve" AWE, as trivially formally intractable. His lab is exploring vital questions of engineering uncertainty applicable to AWE R&D. The killer-application of "supercomputing AI" in AWE may be to understand it at the PhD level, and then pretend one's own wet mind is the very AI that solves AWE, and copy down correctly imagined solutions; before real AI gets its boots on.

    Deep AWE questions are still about fundamental cybernetics. SebastianG's students could ponder the embodied computation of classic kites as generators of flight solutions and relate that as an analog quantum-computing similarity case. They are intending some sort of semantic RL equivalent to Connectionism. Come to think of it, Neural Nets are much like physical rigging of actual rope networks, and how those structures optimize in practice (Golden Age of Sail). Same funny deal with String Theories, that start from plain string, but then few suspect plain string itself is exotic; that master riggers and weavers have advanced secrets. Programmable industrial automation started from looms, and AWE networks will be ultimate "enchanted looms".

    So is SebastianG going to get an NTNU AWE effort up? Won't KiteMill help?

    Great source compilation, JoeF

    We have followed SeabstianG from the start, but the Norway AWE connection now comes to the fore. From his academic background, the optimistic AWE views of his early peer circles, and his glider training, we may suppose his AWE ideas evolve under the pilot's #2 dictum, "Work the Problem" where it leads (#1 is "Fly the Plane"). Hence his current interest in "new approaches is to be able to impose safety constraints for AI-based decision making".

    Where this leads is to maintain a look-up table for automated reactive response to preidentified failure modes. Finding novel failure modes might be an early AWE AI deliverable. Solving AWE exception-handling on the fly will be a future AI marvel. The PIC rules for now, including responsibility for airworthiness.

    Impressive CV. Sebastian even biked solo from EU to Everest. MoritzD is his closest academic connection, with many co-authored papers. SG is a formidable expert in modern theoretic industrial control. The challenge is that AWE is far more complex and dynamic than standard industrial control problems solved in more structured settings. The industrial state-of-the-art must advance accordingly to succeed in AWE statistical reliability, a matter of a decade or more. The current window in AWE is supervisory automation by a Pilot and VO, as required anyway.
