Some software news: 
 April 20, 2016 13:26 ET

 Lynx Software Technologies Provides Certifiable Software Platform for Airborne Wind Energy Generation System LynxOS-178 Is an Integral Component for the Ampyx Power's PowerPlane

MUNICH, GERMANY--(Marketwired - April 20, 2016) -  Aviation Electronics Europe -- Lynx Software Technologies, a world leader in the embedded software market, today announced that LynxOS-178 has been selected as the software platform for Ampyx Power. Ampyx Power is developing an Airborne Wind Energy system with a PowerPlane, a tethered aircraft that converts wind into economical green electricity.

Erik van der Heide, Head of Engineering at Ampyx Power, commented, "To be able to market our technology successfully, it is crucial that we comply with the highest safety standards. Not only should the level of the quality and reliability of our system be high, it needs to be measurable and controllable as well. We have chosen to be able to certify our product according to stringent civil aviation safety guidelines, so we need a software platform that supports us in achieving acceptance by the Federal Aviation Authority (FAA) and European Aviation Safety Agency (EASA) and other relevant aviation authorities. The fact that LynxOS-178 is a Commercial off-the-Shelf (COTS) operating system which has received acceptance for reusability from the FAA for DO-178 certification, and from EASA, was an important criterion in our selection process."

He continued, "The Ampyx Power system represents an exceptional design challenge. The aircraft can fly completely autonomously. PowerPlanes take off, fly and land autonomously from a platform, by utilizing a vast array of sensor suites which provide the autopilot with critical information to perform the task safely. It is designed to spend unusually long periods in the air -- it can remain airborne 24 hours a day seven days a week if conditions are suitable, and is designed for a service life of 20 years. The aircraft needs a software platform of exceptional stability and reliability. LynxOS-178 fully meets that requirement. During the selection process and subsequent development work, we enjoyed a close and productive relationship with the Lynx team."

Lee Cresswell, EMEA Sales Director, Lynx Software Technologies, added, "We are very excited to be offered the opportunity to contribute to a unique system that will create economical renewable energy for many years to come. Ampyx Power's technology is an excellent and highly innovative use case for LynxOS-178, demonstrating its ability to help design teams achieve the accreditations they need to get safety-critical airborne systems to market quickly and with minimal risk."

About Ampyx

Ampyx Power is developing an Airborne Wind Energy system, a 2nd generation wind energy technology. A tethered aircraft, the PowerPlane, converts wind at an altitude of up to 450m into electricity. When the aircraft moves, it pulls the tether which drives a generator on the ground. Ampyx Power is working towards a 2MW PowerPlane with a wingspan of 30m (size of 1 blade of a wind turbine) for market introduction in 2019. Ampyx Power is set to disrupt the energy market due to high energy yield and low cost/kWh, coupled with low visual, noise & environmental impact -- allowing a fast transition towards a sustainable energy mix. Ampyx Power's main office is based in The Hague, The Netherlands, and employs a top notch team of 40 employees. For more information, visit www.ampyxpower.com or follow us on Twitter: @ampyxpower

The implementation of CSR as AWES can be limited by the wind force countering the centrifugal force. Perhaps some level of stiffeness of the rotor could be achieved by using wind force.

Subject: Re: Centrifugally Stiffened Rotor
More than perhaps Pierre,
I apologise for the poor clarity of my written work https://drive.google.com/open?id=0B0qQxFlXu7t-cEt0R052Rko0ZDA
You've probably seen it already.
Reading it isn't so easy.

Where I said
· The conical ring kite shape inflates with oncoming wind.
· A 3mm diameter carbon epoxy rod stiffens & opens the ring kite leading edge.
· The asymmetric driving kites’ longitudinal expansion forces pull the ring open.
and
Longitudinal expansion force comes from the entrained mass of the ram air
kites rotating about the axis, as well as aerodynamic forces due to Anhedral arc
and bank angle.


This implies, I believe, that Daisy uses centrifugal expansion as well as kite dynamic force to maintain the perimeter "stiffness" with tension.

Proof other than video, I hope will soon come from some Scottish universities, interested in small scale studies of Daisy.
I contacted Mark D Moore, (Likes Daisy vids) nice guy. busy guy. hopefully he can untangle my report too.

While we all wait in excitement for AWEC2017: How about trying something new - an Airborne Wind Energy un-Conference (AWEuC)

(un·con·fer·ence: “a loosely structured conference emphasizing the informal exchange of information and ideas between participants, rather than following a conventionally structured program of events.” for a more detailed definition see https://en.wikipedia.org/wiki/Unconference)

I am excited that the MIT Media Lab has agreed to let us use their Unhangout platform for running an online Airborne Wind Energy un Conference! 

(Unhangout is a platform for running online un-conferences. It uses Google Hangouts to create as many small sessions as needed, and helps users find others with shared interests.
Think of it as a classroom with an infinite number of breakout sessions. Each event has a landing page, which we call the lobby. When participants arrive, they can see who else is there and chat with each other. Participants then break out into smaller sessions (up to 10 people per session) for in-depth conversations. UnHangouts are community-based learning instead of top-down information transfer. For details please see https://unhangout.media.mit.edu/about/)

I (Christof Beaupoil) will be your host – but the event will be nothing without your participation!

Please let me know if you:

• Plan to attend 
• Have a suggestions for a session and if you would be willing to host a session

A session can be anything from:

• a formal presentation
• 5-15 minutes of prepared material followed by an interactive discussion
• Group discussion (identify a topic you are interested in, others come to join the conversation
• Your big (or little) question - You have a question you want to know the answer to, and you think others in the group could help you answer it. 
• Show and tell - You have a cool project, a demo, or just something to show and that is the springboard for all the conversation in the session.

Or just join to listen in and get to see me struggle with the latest and greatest in online technology :)

If you are an someAWE.org member you can confirm your participation here: AWEuC-1 or simply go to 

AWEuC-1 on June 17th 2016 at 10am EST

The event will be free (as in beer and in speech), friendly and focused.

Enjoy!

PS: I am using a bunch of new tools to set this up - please be lenient towards me if I mess things up a little - I usually get it right at the second try :)

Some MORE of the things that may be done in our forum:

  • Treat our forum as a conference room.
Arrive and say some AWE things; you have the world of AWE and the world listening (reading) your presentation. Some AWE responders will reply soon or later. The topic you present sticks available for those who may attend today, tomorrow, or at some time in the future. No travel expenses! Wide audience! AWE community members may post. Questions may be posed on your topic! You may post answers to the questions. Form your room by carefully typing a title to your presentation. Attach photos; link photos. Attach posters or link to posters. Attach drawings or link to drawings. Build your topic robustly! Sound files may be attached, if sound is wanted; speech files may be attached, if you want people to hear your voice. Videos with your voice may be attached or linked.   THIS ASSET IS AVAILABLE ALL DAY 24/7/365.  And the record is searchable.   The world may see and hear and read the unfolding awesome AWE sharing.  Spectacular opportunity awaits researchers, engineers, dreamers, scientists, students, thinkers,.... 

Open a topic thread (conference room) on the AWE topic of your choice (search first to see if a room or topic is already started on your concern; then use that active room (topic thread) to CONTINUE the topic with others.

Subject: Re: AWEuC-1 Announcement
How wonderful that geographic limitations of traditional scientific conferences are being overcome. Physical conferences themselves are enhanced by fully engaged online participation. Concurrent super-conferences will be a very social event, especially as active conversations roll around world time-zones. No longer will planners have to restrict AWE content to time-slots cut-to-fit local conference-room logistics.

Perhaps we should just lay down concurrent conference tracks to Moritz's AWEC2017 dates, without him specifically needed to bless or condemn the process. A Seattle-based concurrent track could just be one of any number of satellite conferences. The key integration dynamic is for participation and ideas to flow freely over the conference global  network, with the same social benefits that used to require physical presence. It still seems worthwhile to have serious conference planning, and expect technical presenters to prepare carefully (while also diligently enabling open-discussion).

Subject: Re: Centrifugally Stiffened Rotor

I put again the links for Moore's Centrifugally Stiffened Rotor (CSR) : https://www.nasa.gov/sites/default/files/files/Moore_EternalFlight.pdf and http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/20160001625.pdf .  Within the last  see p. 17: on the table the Specific Power (watts/Ibf) is mentioned as 4.07 with 70 ft diameter, until 3.08 with 800 ft diameter. So in spite of the implementation of rigid wings (with advantages of high L/D ratio, reliability of control, higher lifetime, less maintenance) there is no penality of weight by upscaling. This  interesting characteristic is due in the novel combination of features of this HALE UAV: rotor-wings are in the end of tethers, so their traversed disk area is larger; rotor-wings extend tethers, avoiding a high bending moment; rotor-wings have also means of piloting. The only thing to wish is the realization of prototypes then commercial realizations on the basis of existing studies.


Another interesting feature is that this HALE UAV looks like an AWES with its wings and tethers. It is the first aerodyne planned with AWE culture.


As AWES  some configurations optimizing centrifugal and wind forces could be studied. In one configuration the central hub would be the ground station.

JoeF,

 

p.17 (p. 78 with the Adobe holder) of "Centrifugally Stiffened Rotor

NIA Task Order Number 6528 Final Report

June 1st, 2015" which is on p. 57 with the Adobe holder.

 

About what I wrote as "It is the first aerodyne planned with AWE culture."       My sentence is clear: Here are some definitions:

http://www.merriam-webster.com/dictionary/aerodyne : Definition of aerodyne:  a heavier-than-air aircraft (as an airplane, helicopter, or glider) — compare aerostat;

planned: as a project, not still with an available prototype. With AWE culture: I indicated the free HALE UAV  looks already like an AWES with its wings and tethers. Now I add that Dr. Mark D. Moore studied HALE UAV with also an idea of it as an AWES. So he studied a new sort of aerodyne with AWE culture. In all other examples of AWES the aerodyne (plane, helicopter, RAM paraglider...,) or the aerostat (excepted perhaps for Altaeros but only due to its shape) had their own existence far before an adaptation as AWES, or even as tethered aerodyne (kite).

Thank you, Pierre. The paging assist works. Good. 
=====================================. 

And thanks for the careful clarification on the claim matter. 
Helpful.  That will provide a foundation for critical examination of the "first" claim. 

At the moment, there still are several fuzzy edges to the scene for me; I am working over the claim as I still suspend belief or assent to that claim.  Involved in the scene are some assumptions about what is an AWES. And "first" invites establishing a date for the claim.   I am aiming still to wrestle more on what the qualification "with AWE culture" will do over other potentially competing aerodynes that may have been planned "with AWE culture."  And the dates of the planning for the potentially competing aerodynes will need to be determined to compare with the date for whatever "planned" aerodyne is settled in the claim you have announced.

A collection of historical aerodynes planned with AWE culture would seem to be a preliminary for seeing if the proposed "first" will stick. Accurate dating of the planning would seem to be key in the decision making. Each such planned aerodyne would have attached its peculiar "AWE culture."   As AWE culture is ancient, there may be much digging to do to uncover the various aerodynes that were planned in all those centuries with the associated AWE culture.    The fuzziness of what is AWE may be challenging to some who live in our contemporary AWE culture. 

In all, a daunting task, but appears to be a special adventure.   I have no feeling yet to assent to the subject claim of "first."  And such type of claim seems important enough to win careful scrutiny. Community consensus of some sort would seem to be invited; I estimate we are at a very preliminary stage of process toward confirming such a claim as was made.  "First" means that some other scene was not with a prior on the same claim.  

To start, is there a specific date that fits the planned aerodyne in your focus?  Who planned it when?    

Best, 
 JoeF

MarkM has made a fine contribution to CSR HALE study, but lets also be careful to honor Billy Roeseler's CSR HALE vision in the 70s, which was well explored on the AWES Forum around 2009, with Billy himself in contact. He's also arguably the key inventor of kitesurfing, with his son Corey. These are "KiteGods".

How are we to understand "PI" on the following two pages:
http://www.energykitesystems.net/CentrifugalStabilizedRotors/PIclarifyingForWhat.png

 

 

The two pages has Todd Hodges as "PI"  [Principal Investigator]
and one of the pages has Mark Moore as "Task Monitor". 

2013 notice: :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

It could be enlightening to some readers how titles of PI and monitor are employed surrounding investigations that are funded by NIAC.    

The following are invited to clarify matters. Perhaps there is some document that explains such title matters. 
Todd?
Mark?
NIAC?


==================
So, some funding was given to Mark Moore for 
"An investigation into a new mission concept approach to achieve unlimited high altitude long endurance flight to achieve geosynchronous atmospheric satellites for civil missions."    
And so, how are we to understand "task monitor" for Mark Moore and "PI" for Todd Hodges?

In a different topic started yesterday, the question of "AWE culture" will be given pointed attention. There are distinct perspectives. Pierre seems to opine to restrict AWE culture to only a "few decades" while others see AWE culture as spanning centuries and even millennia; the topic could be fun.  Of course, "first" for something may well depend on how restrictive one is on time periods of activity. 

Similarly for "AWE" there are differences of perspectives. Just what is AWE? The variety of perspectives probably become tools for particular persons or teams of workers/investigators/developers/scientists. Within AWE certain things may occur; that some particular thing occurs does not mean that other things do not occur.  A pointed topic on "What is AWE?" could face the question. 

Aerodynes employing centrifugally stiffened rotors have been extant far before 2013. So, it may be fun to clarify just what Pierre is claiming as "first" for planned aerodyne with AWE culture.  Any fresh tweak of a mechanical principle forms a fresh ornamental object, but such does not remove a potential fact that the mechanical principle may have been evident in former objects.  A new application for a  known mechanical principle may provide fresh projects of various sophistication. New missions using extant mechanical knowns is exciting. 

Two different prepositions have been used in the claim for a first:  "with AWE culture"  and
"by AWE culture".      Paul MacCready was part of AWE culture and he planned an aerodyne way before 2013. So, I am puzzled with this the "first" claim that Pierre places over the planned CSR object.  Woglom planned an aerodyne over a century ago and he was part of his age's AWE culture.  It does not seem the CSR object that is monitored by Mark Moore is first CSR aerodyne and also not first planned aerodyne with or by AWE culture, as prior planned aerodynes with or by AWE culture seem to be historical facts.   This subtracts nothing of the excitement that may be operating for the Eternal Flight mission for a sophisticated CSR object; the mission is fresh and important and being given high-level attention.   First for specific mission does not win first for a generality of "planned aerodyne with (or by) AWE culture."   The generality may bite too large, as counterexamples are  going to be too easy.   Of course, consensus may or may arrive on such questions.

AWE culture?   AWE?
Evolution of AWE culture over the ages?  Ancient AWE culture? 1800s AWE culture?  1900s AWE culture? Gradually the foci within various ages of AWE culture seems to increase; our present year 2016 now has hundreds of foci over AWES at many scales. There seems to be a cumulative richness of applications and devices that come under the umbrella of AWE.
What distinguishes activity in the AWE culture from non-AWE culture? May be find rich aspects? Some propose "conversion of wind energy to other forms of energy for the purpose of lowering human and animal and plant misery or enabling good works to be accomplished or to lower dependence on other energy sources".
Vulgar AWE?  Is an unsophisticated AWES effort discounted as not belonging to the AWE culture? Does high status, big money, deep sophistication only win membership in AWE culture?
Contemporary AWE at all scales?
Does sophistication spectrum allow large community?  Low sophistication?  High sophistication?
Does impressive size of mission win membership over easy low-impress missions?
Does membership in some age's AWE culture require members to have a certain gender, race, citizenship, economic status, social status, scientific status, academic status, religion, notice, ...?   
Does putting kite systems to work qualify for action within AWE culture?

In one age in one geographical area, the foci of a local AWE culture may very well not match the foci of an AWE culture in another locality at some age.  The AWES of the 1800s in the USA different somewhat from the AWES of the 1800s in Germany. Etc.

Notice that any certain person or team may saturate themselves with a certain perspective of what constitutes AWE and AWE culture; and such teams or centers may or may see beyond their own local AWE; some might even declare that "their" perspective is "the" perspective that should rule the age.  Others might simply choose a corner of a larger AWE culture for their focus and mastery without having their corner of AWE be declared as "the" AWE.    

The media, say air, water, plasma, soup, soil, gravel, things, blood ... for AWES operating wings and tethers allow a wide opportunity for AWE workers, designers, scientists, engineers, and users.   Some corners of AWE culture will focus on air, other corners on water, and others with mixed media in some AWES.

Some perspectives grab what one knows and extrapolates that all AWE culture fit into some narrow stream of operations or applications. Other perspectives allow much broader operations and applications.  

All kite systems  in any media put to work at any scale are potential points of welcome for the AWE community that is abuilding in this AirborneWindEnergy forum.  Such flow forms one sector of a large AWE culture stream from ancient times to today.

Pierre,

Please keep in mind, in pure technical terms, traditional kites are WECS; so kite-flying is fundamentally AWE-based. In aviation history both airplane and helicopter evolved from AWE predecessors and the use of tailwinds is a form of AWE which began very soon after aircraft became practical. AWES culture holds. Billy Roeseler in special regard in AWE for developing kitesurfing which displaced powered water-skiing using wind power. Billy is "AWES culture" on many levels, and he developed the CSR HALE AWES concept long before Mark. Give them both credit as part of AWE culture, in balanced fairness

Subject: Centrifugally Stiffened Rotors in Control-Line Aviation, an arch kit
Preliminaries: 
1. Predating manned aviation:  pole flying. 


3. Kite :: set of wings coupled by tethers in tension in media.  Kite systems (kite) are wind-energy conversion systems. The wind may stand for other media other than air, perhaps water, plasma, soup, mud, gravel, soil, blood, photo stream, ...  Kite systems may even be analyzed by having the tether elements be seen as wings. When there is rotation of a wing or tether (a type of wing) then we have "rotor" element. 

4. Control-line flight systems about a hub are arch kite systems with the control-line tether set forming an arch during operations because of the lift and drag pressures on that tether set (a type of wing complex).  

5. Control-line flight systems have two or more anchors. A simple system has a hub anchor and a tip-of-radial-tether anchor. The anchors (tip of lines or hub) may give opposing resistance through various means; the result is a tensed rotor (the tether set which may be simple line or complex structure, but nevertheless a kind of wing or collection of in-line wings; the tether set is a rotor; that rotor may receive various shapes and structures; that rotor may consist of various objects, say pods, drag lines, noise makers, electricity generators, heat generators, light generators, tumbling wings, streamers, banners, etc., but all such on the coupling tether result in a rotor wing, albeit potentially quite complex.  

6. The resistances given by the far-tip driving anchor and the central hub anchor may arrive through use of fuel, wind deflection, jets, electric propelling engines, etc.   When such as fuel is used or electricity is used to power a propelling device as tip-of-tether anchor driving the tip complex generally circularly about the hub anchor, one may say the system is a powered arch kite system employing centrifugal force to gain a resultant tension between the two arch anchors.    The net tension in the tether set will arrive from the centrifugal force and the wind energy conversion from the lift and drag pressures on the tether complex itself.  When both the tip propelling device and the hub device are driven simply by gravity and wind, even though these are sources of power, then one may refer to the kite system involved as an unpowered kite system. 

7. A control-line arch kite system powered or unpowered may consist of one or several sub-arch-kite arms rotating about a given hub. 

8. A hub may be in free-fall or may be further tethered to ground, ship, buoy, raft, other kite system, aircraft, people, asteroids, moving vehicles. Indeed, the centrifugally stiffened rotor with its terminals as arch-kite anchors may be in free-flight, powered flight, tethered flight, unpowered FFAWE flight. 

9. Complexing the tether rotor:   Practitioners frequently in-line rigid wings to complex the tether rotor; such in-line wing become centrifugally stiffened. Ribbon wing sections may be embedded in-line to complex the tether; swivels may be used in-line.  Rigid tumbling wings may complex the tether between the far driven anchor and the hub anchor. Many other WECs may be formatted in-line to complex the centrifugally stiffened tether rotor to given even more complexing of the tether rotor. 

10. One may accept and even want terrific flutter of the rotor complex. One may aim to control the motions of the parts of the complexed centrifugally stiffened rotor. 

11. Notice that a SLK in natural winds is an instance of control-line aviation with centrifugally-stiffened tether-rotor as asymmetries cause cross-winding and essential rotations about the hub anchor below. The tether rotor stiffens by reason of a combination of centrifugal forces from the driving tip wing and the lift and drag of the tether rotor itself (and itself as wing), upon resistance of the ground hub anchor. 

=========
This topic thread invites furthering the centuries-old control line aviation by furthering tip anchor complexes, rotor-tether complexes, and hub complexes.  This topic thread aims to take the seeds of traditional hobby and traditional engineering control-line aviation and further the development of practical powered and unpowered centrifugally stiffened rotor arch kite systems in order to fulfill practical good works. 
=========

I have what I call a "Together Kite" which has two people cooperate; one person become the powered tip anchor running in circles about the other person who is generally still or may move about.  Between the two persons is a coupling tether-becoming-rotor. The tether rotor is centrifugally stiffened during the operation by the apparent wind on the tether rotor and the centrifugal force that becomes evident in the rotation.   I complex the tether rotor with various wings and sub-kites. The AWES works are several:  exercise, health, companionship, entertainment, sound making, education, energy production, light making ...    The Together Kite has the two persons as wings coupled by a rotor (complex tether set). The hub person resists the tip-driving-wing person; the two persons together help create an apparent wind over the rotor-tether-complex; they realize that ambient wind plays its vectors into the net result.   

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

Mark Moore's CSR armed powered AWES in its several formats is part of this wider realm of control-line aviation. Welcome to a special sector of kite energy systems, Mark; please report any and all progress.

Good-eye, Pierre! Joe is an editor of the root Appropedia page in Wikipedia and can correct the omission of kites as a WECS case. It should be clear that "energy-conversion" in its fullest physical sense is what counts, rather than using the omission to define a wrongful exclusion.

Of course you have not seen the Billy Roeseler AWES HALE CSR Boeing paper, or you would not mistakenly insist on MarkM being the originator of the idea. We have email text by Billy from 2009, where he was clearly referencing his pioneering study of HALE CSR rotors, but the per-Internet Boeing report we shared back then is being searched for. Please be patient before concluding no HALE CSR prior art exists, and respect that both MarkM and Billy are friends of AWE, each due his fair credit.

I especially honor MarkM for leading technical critique of MikeB's flawed AWE analysis (the "Magnificent Seven" PhD response). I have high hopes "young" Mark can someday match or exceed Billy's proven career excellence in AWE conceptual design, and kite practice generally, but patience is clearly needed to see just how he gets there.

      The rotor is kited via a far tip end powered propulsion unit.  The driven kited rotor sometimes has rigid wings tensed in line with the tether rotor and tether system. The rotor faces an apparent wind made of the artificial wind combined with ambient wind. Such systems are available for tweaking for specific missions in any media in low or high places.  The tether rotor may be formatted to one's pleasure; tumbling wings may be placed in line on the tether rotor; soft or hard wings may be embedded and tensed via the centrifugally stiffened rotor base; humans may be in pods set on the rotor; devices for making noises, forming interesting motions, generating electricity, drying wetness, showing messages, etc. may be placed on the stiffened rotor.  The driven tether set may be made of one or several lines.   In all, the system is a kite system, but a powered kite system anchored by a central hub and far-out anchored by a motorized driving powered anchor.  The powered kite system of subject is a powered arch kite system, as the two anchors (tip and hub) combined with the tether-rotor set results in a arch for the dominant form of the tether-rotor set. 


      Some thinkers are considering using this fundamental kiting art for various missions to do good works; thus this powered kite system using centrifugally stiffened rotors is an AWES whether or not the hub is further tethered to further anchors or not. The hub may integrate one or more branch powered arch kite systems.  When the propulsion device at the far tip of the arch kite branch is powered only by the wind (and thus not by use of fuel or electricity), then the system is a non-powered kite system (though we respect that the wind powers the tip wing); branched dancing kites comes to mind for the strictly wind-powered non-engine format; in such cases the hub may be fixed to earth or other resistive object which object could be a towing device or a free-fall device or another resisting sub-kite system.

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


      This topic thread is dedicated to the branch of AWES that is control-line aviation where the line rotor (perhaps complex with various formats) and its two or more anchors forms a powered or unpowered arch kite system. Power for driving the anchors for the powered versions may come from fuel, electricity, converted solar energy, human muscles, etc.  Power for the unpowered versions would come from the conversion of wind to get rotational deflection to centrifugally tense the perhaps complex tether rotor wing complex. 


      The intent is to advance the seeds of U-control aviation (control-line aviation), advance what may be done at the far anchor, advance what may be done in good works on and in the perhaps complex tether set, and advance FFAWE relative to these seeds that predate manned flight (around the pole flying).

      Wright Brothers may have been seminal investigators of aircraft, but they did not invent Boeing 747.
       Roeseler being a seminal investigator of centrifugally stiffened rotors (CSR) is evident; he did not invent North American X-15. 

       You are a seminal investigator of some AWE matters; that is not equivalent to being an inventor. 
       Centrifugally stiffened rotors (CSR) are ancient technology matters finding ever new missions. 

       The devices that will further use centrifugally stiffened rotors will be have cause to credit various former actors, not all the same. Most every kite system uses centrifugally stiffened rotors (CSR). 

       seminal: (adjective) (of a work, event, moment, or figure) strongly influencing later developments. 

      Both Roeseler and the Wrights strongly influenced later developments. Their works are still strongly influencing developments.

      Hopefully every poster in this forum will obtain the status of being seminal with respect to some aspect of kite systems.  One need not be the inventor of the core matter that is involved to give strong or significant influence for future or following matters.

      Pierre,

      Yes, Billy was not the PI of MarkM's HALE CSR study. He was not even noted as a historical reference by MarkM's study. In fact, we knew of Billy and his HALE CSR work before we knew of MarkM, and it ultimately fell to us to connect these two figures. Lets hope Billy is doing well, since we have not heard from him in recent years.

      Here in the US, there is nothing unusual about NASA administrative confusion, like Todd Hodges in error noted as PI on the CSR report you linked. NASA commits even worse publishing errors by overlooking Billy's MIT and Boeing work and other key CSR precedents like Payne* and Diehl. NASA even failed to produce the expected CSR prototype, such that a spinning Russian kid with his homemade CSR wing is apparently ahead in actual experimentation (!) Just watch out when NASA finally awakens to AWE on a grand scale,

      daveS

      Note satellite kiteplanes by Payne in figure 3 from his patent, just like Moritz developed analytically.

      "Billy" historically: 
      seminal investigator regarding CSR matters.

      Hodges: 
      Listed by the documents as a PI for a limited contractual investigation of CSR concepts. 

      Regarding your personal Pierre electricity:  rather: Your electricity is potentially generated by kite systems; that is, unless you already are being fed electricity from kite system sourcing. It will be a grand day when one person's whole personal electricity is derived from use of kite systems as source of said electricity. Please report details when such happens within your view. Thanks.

      Pierre,

      The CSR study error in omitting Billy's contributions to CSR is called an error-of-omission. My error was repeating an apparent fact published on the cover pages of official documents. In both cases, no surprise, the primary error was by US government sources, and the corrections came from open-AWE sources. You knew enough about error-of-omission to correct Wikipedia regarding whether a kite is a WECS, with open-AWE help; and now you know the name for such an error,

      Pierre,

      You are right about my error. I believed your source about Todd as PI, and referred to it as if it was true. You are mistaken to belabor minor errors not essential to the topic.

      I made a CSR prototype the other day and dropped it from a tower in glide mode. At least there was no error in the balance and trim...

        She was quite an interesting person.  The Ayer Flapper Fan involved fairly complex unsteady aerodynamics, exploiting a slapping wing action later identified and studied in insect flight. Description from an educational PDF linked at bottom-

        Ayrton Flapper Fan - 1915 

        Used in WWI 

        Smacked on the ground facing the on-coming gas 

        Cross bar of the handle hit the ground first 

        Blade flattens out, sending a puff of air 

        Ground friction slows the lower part of the air, which became a vortex cylinder 

        Central part of the puff advances faster than the edges, and so a ring is formed revolving on itself.
