Editorial: Be ready to explore BHL for PG, for unmanned kiting, and also for specially-framed L&S HGs : ). Step at a time. I like your pattern of bridling the partial second surface (P2S). You have going a single-skin-partial-double-surface SSP2S wing. There will be fully limp and variously-stiffened versions ... a whole spectrum of choices for exploration. Your 1992 simple-skin and now the BHL opens the door to a big future of simple and non-simple SSP2S wing things. The simple will have its important play. And hundreds of non-simple skins will have their play. The space is ripe for very much innovation, exploration, and testing. Non-simple skins of the coming future will include transparency, reflection, billboards, self-healing, smart porosity, solar-energy capture, lighted, robust region self-sensing, turbulence visualization send-receive, fliking tenting, and much more. Inventors of the world, consider playing in Simple-skin SSP2S and Non-simple SSP2S. Dave Barish, at least, put the P2S tech function into gliding and kites; you BarretinaHyperLite and others like XXLite are part of this P2S flow. Fun times. ~JoeF
What fun! Historian Neil Larson forwarded Ken de Russy's special find, the Collector Guy does it again. Neil gives Ken 100 points!
Wow! Ken and Neil,

Great piece of history, guys,
have the measures?
Sept. 27, 2011
When you get a chance to describe the importance of the partial second surface of the XXLite, that would be helpful. One may approximate the measure of that partial second surface from the video; such allows a leading-edge formation that is important. Barish had the partial second-surface tech in the early 1960s making that function and tech into public domain. I have not yet seen the measurements yet on that partial second surface (P2SPG). Safety-wise the matter is strongly distinct from actual single-surface wings, as pitchy parameter is far different. Let us know if the measures come across your view. Thanks!
Best to you and yours,
Discussion in US Hawks:
P2SPG and P2SHG Partial Second Surface
Variable region above ground
level where limp-canopy gliders of single surface (SS) or
partial-double (P2S) or double surface (DS)
have not enough time/altitude to use rescue parachutes when
windfield helicities or turbulence and perhaps pilot inputs have
the limp-canopy paraglider in a form (severe cravatting, collapse,
gift-wrap, compound folding, etc.) that is no longer flying well
enough to halt a severe falling; such results in severe injuries
and death. Just how often such no-recourse arrangement is reached
in paragliding is a matter under grave study.

Notice: 10 Sept 2011 (Southern
The Big Sur trip is fast approaching and while this email is primarily focused on this trip, I want to make sure you are all aware of some other activities coming in the next couple of months and how you can be involved. Please note that I only have email addresses for 72 pilots, so if you speak to someone who hasn’t received this email, please have them contact me if they would like to be on my list or if you want to be off this list, let me know and I will remove you from future mailings. I pretty much only send blanket emails around the Big Sur trip but I would like all the pilots to be aware of the variety of Club and Windsports activities coming up, and especially new Hang 2’s who may not yet be attuned to looking on the Pilot Forum - http://www.shga.com/forum/phpBB2/index.php .
The weekend after Big Sur (October 1) is the club’s annual Dahlsten Cup and Chili Contest - http://shga.com/forum/phpBB2/viewtopic.php?t=2694 . If you can assist Lynn with the planning and execution please contact her directly at email@example.com . This year we are asking pilots to bring ‘hang gliding related yard sale items’ - meaning if you have equipment you no longer use and would like to sell, please bring it to the LZ on the 1st, offer it for sale (could be an auction style, or if you have a specific price, note it) and donate a portion of the sale price to the club. This is an excellent way to recycle equipment you no longer need, gives other pilots a chance to purchase functional gear, and make some money for the club – win/win/win for everyone! Another favorite activity, the rules for the Chili Contest are posted at http://shga.com/forum/phpBB2/viewtopic.php?t=2706 . Come out and vote for your favorite, even better enter your incredible chili in the contest and vote for your own! The more participants, the better. And of course, there will be great prizes for the flying competitions going on all day!
December 3rd is the SHGA Holiday Party. It will be held at the Encino Recreation Center in the evening and is a wonderful time for families to get together and reminisce about the year gone by. A beloved individual is always honored but you won’t know who it is unless you come to the event! Lynn will post additional information at www.shga.com as the event gets closer. That evening, we will also be holding a Silent Auction with items from a wide variety of companies and individuals to raise money for the Club. I already have commitments from several vendors but could really use your help in providing a broad spectrum of items and services. Most of you have probably been to a silent auction but if not it is very simple - items or services are donated and then purchased by folks attending the event. If you have a talent or skill that you would be willing to offer (ie: if you are a masseuse and willing to donate a massage, that is a perfect example) or if you have a favorite restaurant, shop, etc that would be willing to donate gift cards or items, that would be great too. Please contact me if you can provide an item or service. If you would like to help with the evening, please contact Lynn at firstname.lastname@example.org for the party side and me - email@example.com for the silent auction.
And last, I have only gotten three responses for whether the Club should host a Parachute clinic – details at http://www.shga.com/forum/phpBB2/viewtopic.php?t=2656 . Please let me know (or post a reply on the forum) if you would like to see a clinic to be held in February 2012.
Now for Big Sur! Information also available on the Pilot Forum at http://www.shga.com/forum/phpBB2/viewtopic.php?t=2655
Kat Shaw heroically managed to get five spots reserved starting Thursday night, 9/22! Without her, there would be no spots this year as another group was rapidly grabbing them all. Please thank her when you see her! I have attached a copy of the map. Kat was able to reserve spots 29, 43, 35, 36, 37. Yes, we know the spots are not contiguous but they are all that was available in April when we could reserve. IF you are going up early on Thursday, please try and get a First Come spot as we really need the parking spaces. The cost of the space is $25 per night and you will be reimbursed out of the funds collected for the spots and food. Kat and Richard will be parking in 29 and saving their second parking spot for Joe who will be arriving Friday evening; I will be in spot 43 with BJ since we have all the food and cooking utensils. So Thursday drivers, please check into 35, 36 or 37 (or get another spot if possible). We have spot 29 also reserved for Monday night if anyone (besides the Shaw’s and me) are staying over.
All participants: Please remember that this is a WINDSPORTS sponsored trip. Joe has been taking students and pilots up there for about 30 years and has worked hard to establish and maintain a great working relationship with the Forest Service and Campground. Please represent our sport and Windsports in such a manner that the Forest Service and Campground folks look forward to us coming every year.
Currently the cost of the trip will be $30 for those pilots staying 3 nights and $25 for those staying 2. The price is subject to change but should not go up. It just depends on how many pilots actually come (about 10 more than we expected came last year) and how many spaces we end up with. Please pay me and make sure I mark you down on my list. Last year everyone was terrific and I didn’t have to hound anyone J! If you need the detailed information regarding this trip (ie costs, directions, phone numbers, etc), let me know and I’ll send it to you. NOTE: Last year there was no potable water and I have not been able to confirm whether they have it working yet so please plan to bring at least 1 gallon of water per person per day just in case.
Following is the list of the pilots I have heard from. If you are coming and are NOT on this list, please rsvp to me asap! BJ needs a head count so we have enough food for breakfasts and lunches. There are still vehicles with room for pilots and gear, please let me know immediately if you need a ride. The fewer cars up there the better. (Want list, contact Cyndia)
Paragliders run a reach into single-surface,
double-surface, small, large, low-aspect ratio, high-aspect ratio, fully
limp canopy, stiffened canopy, rigidized canopy, and more.
Paragliders are a subset of hang gliders and a subset of kite systems, whereas there are some hang gliders that are not kite systems.

before jumping, but the pilots wanted to hurry and told us we were
asking too many questions,” said Miray Guler. The wife of two years,
after witnessing his fall, suffered a nervous breakdown and was taken to
the hospital in a state of shock. The victim was a mechanical engineer.
The pilot Murat Sait Yeşilbaçar was arrested and accused of gross

huge puff of very fine micro threads that have wrinkle.
From flatland launch points let dust devils place the upper
puff into flow; hope for solid thermal capture of the upper
puff; be pulled aloft. Have wireless control of the wrinkle
sets and the electrostatic status of the thread to control
spread. Go downwind. For landing, zap the threads for good
spread (repulsion) and good wrinkle set as needed.
Cousins to these parahanggliders are the spiders that self-kite; they are often called ballooning spiders, but they are actually using free-flight kite system tactics by using thread-puff strands; the spiders involved get good XC downwind, sometimes crossing large bodies of water to inhabit new territories. The paraglider basic shape has not run its course.

|Historical, commercial, safety,
design --- cooperation from Team OZONE invited
Team, Sept. 21, 2011
A huge flow of wings and airfoils that have been considered "single-surface" for centuries is something OZONE could respect by avoiding term "single-surface" for the XXLite which is clearly with double-surface airfoil for a significant percentage of the airfoil's chord. There are actual single-surface paragliders and there will be more. Confusing the two realms by OZONE, because of the status of OZONE will end costing the PG and kiting sectors much energy. With your status comes a responsibility, I feel, to sharpen the package on this matter. We wish you the strongest progress and wins with your R&D for XXLite; it is exciting; and we were glad to forward the notice into several forums. Others might express on this topic better than I have yet. Destruction of the categories is not needed to win. Old and coming developments need the distinction for historical, safety, design, and commerce reasons. Thank you for keeping the game clear. Change at the points of instruction on your good news is still possible; delay brings on costs. It would be fun to just flow without having to pause ever to distinguish the matter when we cover OZONE's neat and kewl progress.
Great Lift to Team OZONE,
CC: Tech and history group as shown.
|Centuries-old aviation and airfoil culture has a single-surface airfoil sector. Supporting safety, history, clarity, commerce, and opportunity for designing-- form part of the issue. Calling out the clear % of chord that is double-surface would help. When a woman is a little-bit pregnant, then she is pregnant. The substantial significant double-surface (distinct from the upper surface) of the XXLite brings it into the class of wings have double-surface for a significant amount of its chord. Being with status, we hope OZONE will support the needed clarities. Indeed, traditional single-surface wings and coming actual single-surface wings need the respect also. Safety and encouragement of invention are issues woven in this matter. OZONE has been directly asked to consider getting the clarities up front in the early game; they still have opportunity to be in tune with aviation history, culture, and helpfulness for future design, invention, and commerce. ~JoeF Sept. 22, 2011 Posted as reply at Vimeo at video regarding XXLite.|

Paragliding is the act of flying paragliders for purposes not limited to, but including science, commerce, surveillance, photography, recreation, competition, entertainment, travel, and exercise; a paraglider is a gliding-kite system with its resistive hung or suspended payload being inanimate or live. The tether set or suspension lines from the payload to the wing may number from one to several hundred lines; the wing may be fully limp or highly stiffened; the wing may consist of one or several layers using various aerodynamic schemes not limited to the Rogallo wing parawing, Barish Sailwing  single-skin partial second surface, William Allison battened sled  and Scott sled, or Jalbert parafoil . Paragliding use scales occur in small model unmanned forms, manned formats, and huge scientific working formats. Recent sport and recreational paragliding has more Domina Jalbert parafoil users, but definitely not exclusively. There are aeronautical engineering and sport definitions of paragliding that have mismatch as private organizations carve out sport and commercial territories; the rich patent systems of the world retain robust opportunities for the paragliding sector of aviation.
When a paraglider at any scale is coupled with a powered propulsion system that is turned off, then the system remains a paraglider; when the power is turned on for enhancing or negating the glide, then the system is a powered aircraft; this occurs in model and large scientific versions; the sport realm is called powered paragliding (PPG). Paragliders may have passive or active controls at any system size for guiding the system to targets; targets may be ground targets, landing zones, or regions of planetary atmospheres that have sustaining-flight updrafts or thermals. Model and manned sport paragliders may stay flying unpowered up to the limits of endurance of robots or humans controlling the flights, and limits by way of available lifting media currents (artifical or natural). Travel of hundreds of kilometers have been recorded for sport manned paragliding. Methods initiating paragliding flights include at least these: foot-launching, tossing, slinging, towing, dropping, on-board powering, aero towing, towing by friends, deployment from aircraft, deployment from spacecraft, deployment from rockets, self-kiting from fixed or moving anchors, boat towing, or separation from parachute or balloon system.
The paragliders that are fully limp are more portable than those with highly stiffened parts. Small model paragliders may be tucked into a person's shirt pocket for deployment indoors or outdoors. Manned sport paragliders of the limp-canopy sort are often so bag packed to be carriable by the pilot onto a city passenger bus or small automobile, even as a backpack or rucksack. Generally, the more stiffeners employed in a paraglider, the larger is the tote pack. Larger scientific and industrial paragliders have required trucks for ground transport. The pilot-carriable limp-canopy paraglider for sport paragliding has proven to attract large numbers participants; picture four pilots in a small utility vehicle that also holds their bagged paragliders.
|In the Talk Page of the article we find:
Serious neglect of "paraglider" categorization and branches
The paraglider is definitely not just the Jalbert ram-air wing culture; that is one branch of the paraglider; there are firm mechanical branches of paraglider that stream into aviation of its beginning to now that are strictly not Jalbert ram-air parafoiled kite-glider wings. The patent system still streams with the solid non-Jalbert-parafoil paragliders. We do serious injustice in a narrow POV article that serves only one of the branches of paraglider used in aviation; the contemporary manufacturers of the fully-limp Jalbert parafoiled wings have a lot to gain to keep the narrow POV going in this article. David Barish did not use the Jalbert parafoil; rather he used the single-skin partial second surfaced airfoil wing to do free-flight-kite gliding that forms a branch of paragliding. NASA very starkly used framed paragliders for manned and unmanned paragliding. Tony Prentice in 1960 importantly made and used a string-controlled free-flight framed paraglider. The full branch of paragliding that uses the Rogallo Wing parawing paraglider is also definitely not a Jalbert ram-air paraglider. The stream of patents in the world that still use "paraglider" as the proper term for boomed (inflated and sticked) sailed gliders is strongly part of the fertile core of what a paraglider is. Not all hang glider are paragliders, but a very large segment of hang gliders are paragliders. Mechanically, it is rawly recognized by many experts that the string-controlled free-gliding kite system (payload or human body as resistive anchor, tether set, and kite wing)is a parachute-like-glider system, thus para-glider or paraglider; such terms and recognition was in the roots of aviation, teased into existence by the strong influencing book by Woglom in 1800s with "parakites" Parakites by Woglom as the rooting term; just have the anchor be free-falling rather than a moving human hand running or tree swaying. To let the one branch of current manufactures try to wipe out the rich fullness of paragliding for their own purpose of fast sales and profit is to cheat the readers of the world of robust paragliding opportuniy. Editors are invited to fully know and integrate a much more accurate presentation of paragliding than exists in the article of Sept. 2011. One editor in particular keeps carving out his POV that supports the narrow POV about paragliding to the unfortunate neglect of the richer fuller story of paragliding; he uses impolite language in this discussion space to rashly slam some of the other editors as progress evolves. That editor is asked to deal with a neutral stance and quite forcing the article to serve just the narrow Jalbert parafoil commercial sector; that editor seems not to know that both historically and contemporaneously that the limp string-controlled Jalbert wing used for free-flight kite gliding is firmly a sector of hang gliding, a true proper subset of hang gliding, whereas hang gliding encloses some non-paraglider systems. There is much work to be done on this article, if we are going to serve the world's readers with a neutral encyclopedic presentation of paragliding. Joefaust (talk) 15:45, 30 September 2011 (UTC)
