Fugitive paraglider with resistive element being Racie and apex wing being Realie and tether set of size one line.

We notice that one-string paragliders come in a great variety of sub-families. Of course one family is the very short one-stringers where the pilot can grab the wing to assist in control of the flight; these are defaulted to the term kite hang gliders, but they are still one-string paragliders: Eaglet Hang Gliders: Epic Every Day!     Different are the one-string paragliders where the pilot may not be able to directly grab the wing for control operations; the piloting robot or human pilot of tese use other means to control the flight; one method is direct handling of string in jerks; but other means include control servos that operate on the wing surfaces or strings of the bridle to wings.    Paragliders that have more than one wing in their wing sets may still be a one-string system; control could be passive or active; active could be programmed robot or human on or off board.  Paragliders are Gliding Kites Part001

Direct non-mocking questions on topic were welcome; also welcomed: off-topic questions via PM.

Oct 27-Nov.2, 2011: one week: not one non-starter's post has made a direct effort to explore the topic.

The topic is NOT my idea which Woglom started at least by 1895:
"This thread invites the exploration of paragliders
of exactly one string in their tether set."

There will be advances for several types of one-tether paragliders.
Anyone interested will find ways to share their tech.

This is my last post in this thread.
I will check to see, if--over the coming years--
anyone advances the topic in PGForum.

A gathering of the world's tech on this topic will grow
in WPGA files free to anyone. Anyone's notes on topic will be welcome.

Designed by YuKwang Kang & Jinsu Cho, the Dreamfly Kite does feature LED lights so that it sparkles in the nighttime.

One-string paragliders     #t=1
PG Activity Sector
(Note: This sector is distinct from multiple-lined "one-riser set" paragliders like SOL T1L      SOL Einleiner T1L  where the A-set consists of many tethers along one spanwise chord-station line.)

Discuss here:

  • The one line may be electrically conductive.
    • Electricity may be sent up to wing set w or from w to the resistive set r.
    • Electricity may be generated during flight or brought onboard for the flight.
    • Electricity may be used to drive control surfaces in the wing set or in the one line.
    • Electricity may be used during the flight by events in the resistive set.
    • RATs on wings or the tether or in the resistive set may be employed.
    • Let the surfaces of the wing set w be solar-energy converters; collect the energy in the resistive set of the paraglider. Let the collected energy be used for various purposes: charging instrument batteries, keeping pilot warm during soaring high, driving lamps to illuminate the paraglider's kite tethers and surfaces of the resistive set or harness or helmet, etc., present digital messages on the upper and lower surfaces of the wing elements, charging batteries for driving emergency propulsion devices for landing scenarios or other emergency scenarios, or for bringing down charged batteries for use in camping scenes when flying is not being done.
    • The pilot set as part of the mass of the resistive set of a paraglider is free to move his or her body; those movement could be used to drive a generator to make electricity. The movement of the pilot's body could benefit by giving healthful circulation, by burning calories to bring warmth, by keeping the pilot awake for piloting tasks. The generated electricity could be used or stored; use could be for devices in the resistive set, tether set, or wing set; thousands of possible uses onboard the gliding kite (paraglider) may be explored for particular niche applications and purposes.
    • Use electricity to collect water from the atmosphere. Drink the water. Or use the water for making electricity by using some of the electricity. Or use the electricity to filter pilot relief urine and change the water to hydrogen and oxygen; save the hydrogen for emergency energy or for inflating balloons for special uses during the paraglider flight.
  • The one line may be hollow and be a means to transfer air, water, or other gases or fluids or even balls or flakes of special-use materials.   In huge paragliders there may be elevators inside a large line for transporting passengers up and down the line to the wing and back to the resistive part of the paraglider.
  • The one line may be short, long, or very long.
    • Short lines are seen in paragliders that receive the default sport name of "hang gliders" even though other paragliders of long lines in sport paragliding are mechanically also hang gliders, but such do not frequently receive in the sport such naming, but rather "paraglider."
    • Moderate long line was described in 1896 about an 1895 incident of fugitive parakites coupled. Woglom describes the matter.
    • Very long line has played in the Dale C. Kramer soaring paraglider system that was earlier described in function in 1967 by Richard Miller in his book Without Visible Means of Support. But that is just one very-long-line solution to this one-string adventure challenge.   Here radio control of both terminal wings is an option, though a human pilot could be in either or both terminus wing sets for direct control.  The upper w may well be in different wind than the lower w. Upper w and lower w are coupled by the single tether. Dale admitted he was just having fun with the showing of the Eddy kite for the upper w; actually upper w could be a set of high-performance wings or another sailplane, etc. Such a paraglider is being studied for serious industrial purposes include mining the energy from working the two terminus ws to drive generators; many options may answer.   See Dale's patent application.
  • The line may be textured, tapered, variously shaped and various compounded, even with interior sub lines shrouded by the one tether shrouding. On huge paragliders, a human elevator may occur inside the one tether.
  • Learning to climb the one tether...; learning to slide down or lengthen the one tether. Fast climbing puts more load on w.  Rapid lengthening the one tether relieves load on w. Accelerated climbing and lengthening the tether is a form of changing the wing loading by choice.
  • The line may split to bridle the wing set, but just one line meets the resistive set r.
  • As always, the wing set may contain one or more wing elements.
  • The one tether may be streamlined and perhaps fixed with its chord perpendicular to the span of the first wing element.

  • The one tether might be with flaps high or low; pilot might control the flaps to adjust the drag high on the tether near wing to help pull the wing back.

    Wing set (w), tether set (t), resistive set (r) :: gliding kite :: paraglider.
    Explore unmanned and manned versions. Allow count in w to be one or more.
    But for the t just allow exactly one line to r where r may consist of one or more elements.
    There is evidence of a spectacularly wide opportunity; we in this forum over time may
    play a part in unfolding that opportunity. Have fun doing so; but also play your technical best, and your highest imagination.       PGF277212   Oct. 26, 2011.   And here:

Translation: "I have no bloody clue how to take off with this thing but you could give me some ideas about how to build it." 
Here's an idea Just tie the tether to an airliner flying a continental route and wait for the plane to take off. You can add the wing ladder anywhere between you and the plane. This would still be considered free flying since you did not pay for the ride

Good! Now you are on a roll. That is a neat turn on "free". Thanks. This will remain a gem in the related matter, Monos. 
Surely a charge would arrive in the mail; and court actions would follow, if the charge was not paid; authorities would see the tactic as stealing a ride. So, maybe not "free" afterall. 

Monos, you actually come close to what we have already published as one of the many methods for paragliding across continent using single-tether paraglider. We have already delineated aero-launch with variety. Releasing from a hitch-hike from a powered aircraft is one of the known methods of setting into flight a glider. Aero-tow AT, as you well know. The AT solutions are well known have their place in the effort and in other kite-energy placement efforts. While being tugged the kite you describe is not gliding, so at that time the system is not a machine paraglider. Releasing to glide gives a gliding kite (paraglider); and then the challenge would be to soar across the continent and that would take time; so consider the need for sleep as you explore your imagination further for the task. Have fun. 

Two things: 
1. It is more pleasure for me to give lift to others' ideas in gliding kites than presenting my own. My record on this is solid for over 40 years in paragliding publishing others' ideas. 
2. I have four distinct methods that are not AT to share in drawings to the PGForum. I am awaiting permission from the Moderator Team to begin posting the drawings. 

Your neat gem will remain present in the kiting literature that we serve. Thanks for the contribution. 

Best of lift to you and yours,

Rod B, thanks for the effort on translating. Some translation is on target, some not.   Here is some sharpening of the translation effort:

New postPosted: Mon Nov 07, 2011 2:58 pm    Post subject: RE: Exactly one-string paraglider Reply with quote 

What we need to take into account is Joe's attempt at renaming everything.    
Rod, not renaming, but naming by mechanical generics; the items are not new; if you are unfamiliar with a paraglider being generically mechanically a gliding kite, then some disorientation might occur for you for some time.  And your use of "everything" is far too wide, Rod; such is not the case.  Just a couple of terms recognizing mechanical history, not a renaming. 

He has, in the past, referred to paragliders as kites, paragliders as hang gliders, hang gliders as paragliders, and just about everything as gliding kites.  
Rod, care is to be taken on the third item in your mentioned series, as not all hang gliders are paragliders; e.g. when no tether is involved inthe hang glider, then kite hang glider cannot be, and thus paraglider cannot be. The short-single-tethered Falcon 3 by Wills Wing is a paraglider as it is a gliding kite; but Otto Lilienthal gliders where hang gliders that were not paraglider hang gliders, as he placed his body directly on the airframe to let gravity do its powering.   And your exuberance goes too far; do you overstate like that just to hit?    Things are simpler: gliding kite is paraglider (type of hang glider), but there are hang gliders that are not paragliders.

Quote: "single short-tether gliding kite paraglider" = hang glider         Yes.
Quote: "multi-long-tethered hang gliders" = paraglider          
Yes, when in gliding flight, we are presuming.  

And now we can add: "single f...-long-tethered paraglider" = brainless kite idea         
Rod, you dance on the grave of Woglom, Miller, and on the living legend of Wayne German and Dave Santos, and on patent applicant soaring champion Dale C. Kramer.  To achieve what is feasible at various scales in this matter of gliding-kite (paraglider) is taking considerable brain investment by many workers.   You are invited to apply your brain on this paraglider matter. Explore perhaps how much aerodynamics can be applied to the set r  where itself may be a wing set. And notice that control centers may be in r or in t or in w or in all three sets or two of them in combination, or from some remote RC ground or aircraft point; the controls passive or active will affect the aerodynamics of the elements in r and the elements in w.   The single line in t will be made visible to other aircraft by one or several means. 

So, now armed with the correct tools for the job, we can do a little translation to get at the core of Joe's last message [with minimal editorial guidance]: 

Happy Very Happy to predict that a very long single-tethered paraglider will set extreme world records for cross-country travel with humans aboard.

I'm happy Very Happy to predict that a kite with a very long line will set world records for cross-country travel with people aboard.   
Rod, the slippery translation is technically correct, but in context it would be stronger for readers to have emphaszed that the kite is of a sort that the r of the kite is moving in the air stream  in fall mode and in a manner that the r is part of the full gliding resultant.  Some of your readers will have a habit over "kite" as being with r set soiled only, which is much too limiting.  The "kite" involved is a gliding sort with its integrity moving along the air stream and not soiled.

Controls of the unpowered paraglider will effect attitudes in the upper wing and attitudes in the lower resistive subassembly.

The kite will be controlled from below. [Great idea!]      
Rod, as noted above in confirmation, the gliding kite (paraglider) could be controlled from above at w, from t above r, from r, from both w and t, from both w and r, from t and r, for from remote RC control from ground stations or other aircraft or combinations of the noted placements of control. The challenge is not limited to "below."

Dale C. Kramer has for years been mapping out flights using detailed weather reports.

Dale C. Kramer has been planning flights using detailed weather reports for years. [Wow!]    
Rod, his Lazair success is part of his pattern; his soaring wins are part of his pattern; his professional services to soaring are part of his pattern. His sharing his paraglider trans-continental planning has been a careful intensive work; he shared long-flight simulations and planning at our AWE 2009 HAWP conference in Chico, California. I introduced him to Richard Miller's earlier work on topic and the contemporary work by Wayne German, Dave Santos, and myself.  Tracking the wind strata and planning the flights is no simple matter; the long tether and the positions of r and w and the needed controls form a strong challenge for engineering.    Launching methods are being studied. Risk management is no small matter. We do not want to drag r across highways, buildings, powerlines.   Unmanned version of 1895 had some success, but we are reaching for fully controlled trans-continental paraglider flights with humans aboard; humans may be in r or in w or midway in t or in two of those or in all three of those placements. And we are studying if the team aboard should be more for shift work or whether controls will be strong enough to allow sleep and alerting systems to suffice.

No fuel for lift.

The kite will have no motor.     
Rod, again it might be better to help the reader know that the "kite" is of the sort "gliding kite" in free-flight mode without soil contact during the flight.   It is also key to note that there would be no fuel for lift, but that is not the same as your translation.   There may be energy-gathering from the flight and that energy may be used to perform controls, performed obstacle lighting, perform communications, perform warming, etc, but not lift. Lift will come from r and w using dynamics of the winds alone.  There may be motors for control, but not to propel for getting lift. The result would not be a powered paraglider, but just a paraglider. You personally have exercised your muscles to effect control on the lines to alter w in your gliding kite (paraglider); you are the control motor in such case.

This is a proud future for machine paraglider.

One giant leap for mankind, one small step for kites. [and one f... long string]      
Yes and no and yes. Mankind has not yet achieved heavier-than-air paraglider flight of humans across a continent in one flight session; this will be no small step for kites (of the sort: gliding kites with humans aboard).  And yes, the string will be long in order to utilize wind strata differences. The demonstration will usher in a New Aviation option where goods and people will be able to travel without fuel for very long distances.  Though unmanned feasibility demonstrations have occurred, the stark human travel in such a paraglider is yet to be achieved; balance of parameters is needed, not new science. Craft, testing, daring ... are needed. We were hoping a free flying duck might be part of the flight crew.

Clearance for the record flights will be specially given by airspace governance, as the long line will be obstacle and the airspace used will be that which is frequented by commercial aircraft.

The kite will be filing an air plan.     
Yes, that will be needed; other aircraft will be affected during a major effort; resistance from the businesses that run other aircraft will be significant; perhaps we can include them in some advertising deal to help get the flight plan permitted; we are considering carrying logos in the paraglider and in news references concerning the project.  If the effort becomes a matter of national pride, then major players might help it all happen over their respective continents.     One flight over Australia, over Africa central, over Europe, over Asia ...   best paths and times are being studied.    Records will be set; some first flights might be short; perhaps a starting point is one calculated by Kramer: just officially beat the sailplane distance record. Then go from there with more robust efforts.

As the physics allow cross-continent paraglider flight, it will be permitted at least once.

The kite will be allowed access to controlled airspace.   
Rod, again the translation could be sharpened for project purpose: "the paraglider (a gliding kite) will be allowed to use controlled airspace."   Your readers might be keeping their feet soiled; consider helping the project by seeing the paraglider aspect where mechanically there is the gliding kite unsoiled during the flight.

Moderator Team: May I attach drawings and documents illustrating these matters?

I have been such an unscrupulous git in the past, by changing website images in forum conversations, that I am no longer allowed to post links to external images. However, my grasp on all thing technical is so limited that I have failed to realise I can still upload images to the forum as they will be uneditable. [I'm just guessing this one!]     

Rod, the Moderators are apparently not allowing me to show drawings; I am asking directly for permission as I do want to keep peace with the Moderator Team.  I asked specifically about several ways to show images; the Team did not answer to the specific methods wondered about; they just put a general command; the matter is still fuzzy; others are allowed external image calls and video.   Rod, I am in the habit of updating images to express progress or accuracy. I did not appreciate that someone would be disturbed by one editing one's own graphics; but the Moderator Team might have a challenge with such; so I await direct permission to either upload images to the forum server or to images in my server; I asked directly for clarification and only received back a dictum that has me wait for direct permission now. 

Executive summary: he predicts that in the future we will see a kite flying very high with a long line and people hanging under it.  
Rod, it is that a gliding kite will be used, that is, a paraglider.

Executive conclusion: there are wealthy Americans willing to have a lash at anything just to get in the record books.   
There are also others in other nations willing to set records; the cross-continent paraglider one-session flight is open to any person on earth; interest has been shown from many nations already; some coordination is occurring through the
AWEIA.     Some notes are on: HERE.

Rod B,  the IKAROS has more than one tether to a payload tethered center. The IKAROS  is doing is special travel in non-air realm and is lauded.     We are seeking planetary atmospheric gliding kite (paraglider) successes.

Great Jonty:  A forum with its resistive set of rules flying threads that hold winged conversation blown to lift by the imagination of participants may be thought of as a metaphorical kite.    Inspired by the post of Jonty Lawson, November 7, 2011.  Of course, this kind of kite is a big contributor to human society and to history.   Keep those kites flying! 

http://energykitesystems.net//WPGA/images/GlidingKites/lengthenline.jpg    ASKED on Nov. 8, 2011, MODERATOR TEAM if I may show the graphic to members.

A RELATED dynamic launch method is to anchor oneself to the ground; kite a wing set very high; upon passing thermal, release pilot pod from ground hold and use motorized line climber to make the long tether become short; climb faster than the system sinks. Continue soaring.



Research question:  Idea Idea Arrow Pause to focus on free-flight #t=1 PG of very long tether (VLTPG) line ascending and descending: 
Call for essays posted in this thread topic on that matter (or links to your essays). How to, challenges, purposes, ...? Line climbers, rate of climbs, pilot-powered climbing, stored-pilot-power powered climbing, descending on the line, rate of descending, offers from mountain climbing, etc. Why go up or down the very long line during free flight? Accelerated climb loads the wing set w; free-fall lowers the load on the wing set w. Consider special scenarios where climbing or descending on the line would effect some mission or task. How might ascending the line or descending on the line affect launching tactics or landing tactics or flying tactics? Could there be tethers that shrink or expand by way of electric or light or oscillation triggers? What have we on this? Take your time. Have fun. Very Happy Idea 






The single-tether between lower r and upper w gave some an uneasy feeling and wanted nothing to do with it:

Click image for fuller instruction. The total system is simply a paraglider (gliding kite; here with r quite aerodynamically reacting); how well the r and the w are controlled results in various XC paragliding flights. The upper sketched wing could be replaced by any wing set that would be mission helpful. The fundamentals were expressed in 1828 and revisited in 1895 and at other points including Richard Miller in his 1967 book. Low & Slow continued some focus on the long single-line paraglider (line between lower r bridle and the upper w bridle).
Similar dynamics with changes in the size of forces ocurs on gliding kites (paragliders) like WW Falcon 3 and also those paragliders that feature soft canopy string-formed and string-controlled w.

Legend: r is the set of objects at the lower end. And w is the set of object at the upper end of the long tether. The tether set t in this post is with a count of one: #t=1

What team of pilots will be first fly from Pacific coast of USA to Atlantic coast of USA in a paraglider in one flight session using a long single tether between the system's r and its w? Recall that w may consist of many wings in say stack or branching or tree coterie, etc. Place visibility markers on the long tether. Have means to notify other aircraft of your presence. I nominate Jim R to be on the team.
