Regarding the "Crutch Solution"
Note overall: When "tube" is mentioned, be ready that inside that tube may be telescopic tubes or other rods, bars, things.
"User" is Joe, yours truly. I prompted the AI ChatGPT 3.5 that was trained over a limited part of the Internet to September, 2020; the AI is quite limited in some ways and also will produce errors and and "hallucinations."
Note: when wrapping the sails onto the body of the crutch, a firm tight wrap may be wanted; so, starting the wrap, there could be cinching of the first edge of the wrapping with the tube set of the crutch. Then upon wrapping, keep thing snug; then to finish the wrap, somehow keep a tension on the ending edge of the wrap. Then also put a couple of straps around the wrap; and somehow secure the near-armrest edge of the sail wrap so that the sail never sluffs down vertically.

Crutches made of parts all of which will become parts of a hang glider(HG): each crutch will be formed of four tubes of five-foot length; two tubes will be one side of the crutch; two tubes will be the other side of the crutch; a space will be between the two sets of two tubes. The space will have an armpit rest. Below the armpit rest will be a space that is 4 inch by 2 inch by 48 inch; that space can hold other HG batten ribs and line sets. The trekking-bus-using HG pilot could wear a back pack of 3 inches thickness so as to bother other bus riders; the pilot could also wear a chest pack that is 6 inches thick; the back and chest packs will nicely finish appearances of a person with 12-inch wide crutches. Personal space will be easily discernable. The crutch from the height of the armpit rest down near the ground will be about 12 inches by 2 inches by 48 inches; that area of the crutch will be where a half-sail will be wrapped; left wing sail on one crutch and right wing sail on wrapped on the other crutch. Key design: the handhold of the crutch will be specially designed: hat two cords; each cord is anchored as follows: one anchor is near the foot of the crutch; the other end of the cord is at the armpit rest area; the other cord is similarly anchored but on the other side of the one face of the crutch; notice that the two cords are on the outside of the wrapped sail.

A trekking hang glider pilot very well may need mobility aids. The pilot is trekking to a flight site where vitality will depend on being ready to physically participate well in the takeoff run, the controlling of flight, the landing physical challenges, and the trek home. A TPHG (tiny packed hang glider transformed into two crutches, a backpack, and a chest pack) has weight; aides to trek such weight is vitally important. Forming the TPHG into the two-crutch and two-pack format results in a mobility assist that may help keep the pilot alive and healthy. The format of the HG into crutch and pack form provides a neat well-formed non-threatening appearance for bus riding; standing on the bus will hardly take any more space than a person ordinarily takes; if needed, while standing on the bus both crutches could be hugged by the pilot in front of the pilot's body.

ChatGPT
It sounds like you're describing a creative solution for hang glider pilots who may need mobility aids to transport their hang glider equipment while trekking to a flight site.

User
Are you appreciating that as a pilot, the mobility assist of the crutches does not require that the pilot be physically challenged in the ordinary sense. The very act of the day has it that the pilot needs to be fresh for flight else accidents, injury, or even death may occur. So, forming the TPHG into the crutch system will help assure safety for the day. So the crutch format is for pilots that may need crutches for ordinary days and for non-physically challenged pilots who need assists for a flight day where trekking and bus riding is involved.
ChatGPT
I understand your point now. The use of crutches in the TPHG format is not necessarily for pilots who are physically challenged in their day-to-day lives but rather for hang glider pilots who need additional support and assistance specifically on the day of their flight to ensure their safety and well-being.

In this context, the crutch format serves as a means to conserve the pilot's energy and physical condition for the flight itself, which demands optimal physical and mental readiness. It's a practical solution to address the unique requirements of hang glider pilots who need to trek to flight sites, navigate public transportation, and ensure they are in the best possible condition for a successful and safe flight.

By transforming the hang glider equipment into crutches when needed, it provides pilots with a convenient and efficient way to prepare for their flights without putting unnecessary strain on their bodies during the journey to the flight site. This approach aligns with the goal of ensuring safety and minimizing the risk of accidents, injuries, or other issues that could arise from fatigue or physical strain before takeoff.

Yes, you got it! Further, after getting off the bus, if there is a significant trek to the flight launch, then the following may be arranged: Put the two crutches in a stack on the ground with the long flat sides of a crutch horizontal to the surface of the Earth. Then mount a small set of wheels at each end of the stack; place the flat backpack and flat chest pack on the stack of crutches; strap the packs to stack of two crutches. Presto! A wagon has been formed. The pilot can simply pull the arrangement to the flight site.
ChatGPT
Your description of transforming the crutches into a makeshift wagon is a clever and practical solution for hang glider pilots facing a significant trek to the flight launch site. By mounting small wheels at the ends of the stacked crutches and securing the flat backpack and chest pack to them, you create a portable and convenient means of transporting your equipment.

This "crutch wagon" approach offers several benefits:

Ease of Transportation: Pulling the wagon is much more efficient than carrying all the equipment manually, especially when covering longer distances.

Reduced Physical Strain: It minimizes the physical strain on the pilot, ensuring they arrive at the flight site in better condition for the flight itself.

Equipment Security: Strapping the packs to the stack of crutches ensures that the hang gliding equipment is securely held together during the trek.

Adaptability: The setup can be easily disassembled when it's time to prepare for the flight, allowing the pilot to efficiently transition from transportation mode to hang gliding mode.

This innovation shows how creative thinking can lead to practical solutions that improve the overall experience and safety of hang glider pilots during their journeys to flight sites. It's an excellent example of problem-solving in action.

Focused note on wrapping stack of sail segments onto crutch when Double Castle scheme is used:

User
A hang glider having left sail and right sail where each half sail is separated from the other sail half. Have the sail use the Double Castle segmentation where batten-ribs at flight time seat in the double columns of castles. With the batten-ribs out of the castles and the JBHL line in place and the sail segments are accordion folded to one stack of sail segments. There will be short chord sail segment. Wrap the stack of sail segments on a crutch of parallel sides by locking the first edge of the longest sail segment to the crutch; be sure to have the shorter chord sail segment facing the inside of the wrap so that the longest sail segment remains the outside of the wrap and holding all inner layers of sail segments essential captured. Wrap the stack snuggly by use of gravity and hand smoothing methods to keep air captured to a minimum. To do such wrapping rains the crutch and have the crutch support at two ends by some method. Then after the sail stack is started, rotate the crutch once and thus enable another half-round of the wrap; smooth what is wrapped and let the remained of the stack hang to ground. Then rotate the crutch again and smooth the wrapped portion again. Do such rotating and smoothing until the sail is full wrapped. To finish, grab the final edge of the sail and have a set of four bungee assist cords. Mount the crutch's hand-hold four webbing; that webbing will be an anchor for the four assist bungee cords that will keep the sail in a tensed wrap. Then use two straps that have hook and loop; perhaps the straps could be elastic webbing. Wrap those straps to snug the sail on the crutch. Do the same for the other wing's sail on the other of the two available crutches.

ChatGPT
It seems like you're describing a specific method for folding and securing the sail segments of a hang glider. This process involves carefully folding and wrapping the sail segments around a crutch to ensure they are stored and secured properly. Here's a breakdown of the steps you've described:

Segmentation: The hang glider sail is divided into left and right halves, and each half is further divided into segments. These segments have batten-ribs that fit into double columns of castles.

Accordion Folding: The sail segments are accordion folded into a stack. This means that they are folded in a zigzag fashion to create a compact bundle of segments.

Crutch Placement: A crutch with parallel sides is used to support the folded sail segments. The first edge of the longest sail segment is locked onto the crutch.

Orientation: Ensure that the shorter chord sail segments are facing the inside of the wrap, while the longest sail segment remains on the outside. This arrangement keeps all inner layers of sail segments captured.

Wrapping: Wrap the stack of sail segments around the crutch by using gravity and hand-smoothing techniques. The goal is to minimize the air trapped within the wrapped segments.

Rotation: Rotate the crutch periodically during the wrapping process to enable another half-round of the wrap. Smooth the wrapped portion after each rotation.

Repeat Rotation and Smoothing: Continue rotating the crutch and smoothing the wrapped portion until the sail is fully wrapped around the crutch.

Final Edge and Bungee Cords: Once the sail is fully wrapped, secure the final edge of the sail. Use four bungee cords attached to the crutch's hand-hold webbing to keep the sail in a tensed wrap. This helps maintain the tightness of the wrap.

Strap Wrapping: Use two straps with hook and loop (or elastic webbing) to further secure the sail on the crutch. These straps will help ensure that the sail remains snugly wrapped.

Repeat for the Other Wing: Repeat the entire process for the other wing's sail on another crutch, as it appears that you have two crutches for this purpose.

This method seems to be a detailed procedure for folding and storing a hang glider's sail segments to keep them well-organized and secure. It's essential to follow such procedures precisely to ensure the safe and efficient use of the hang glider when needed.

Write a short story of 1000 words or so about a hang glider pilot who tiny packs his hang glider for polite riding on the local city buses, converts th hang glider pack into a wagon that he pulls as he walks from the bus stop to the flying launch site.

ChatGPT
In the heart of a bustling city nestled between towering skyscrapers and endless traffic jams, lived a man named Leo who had an unusual passion – hang gliding. He wasn't your typical hang glider enthusiast, though. Leo had a knack for turning heads and sparking conversations wherever he went. It all started with his ingenious idea of "tiny-packing" his hang glider.

Leo had always been a dreamer. As a child, he marveled at the birds soaring through the sky and wished he could fly like them. Growing up, he never lost that fascination. When he discovered hang gliding, he knew it was the closest he could get to realizing his childhood dream. However, there was a problem: the city he lived in had strict rules against flying from most locations. The nearest hang gliding spot was several miles away, and public transportation was his only option to get there.

Undeterred, Leo decided to find a way to combine his love for hang gliding with his reliance on public transit. He began experimenting with ways to shrink his hang glider into a manageable size. After countless hours in his garage, he finally succeeded. He created a hang glider that could be folded and packed into a backpack no larger than a small suitcase.

With his tiny-packed hang glider in tow, Leo became a regular on the city buses. He'd board the bus in his casual attire, backpack on his shoulders, and a smile that could brighten anyone's day. Passengers would often ask what was inside his bag, and he'd reply with a wink, "It's my little secret."

But Leo's secret didn't remain a secret for long. One sunny morning, as he boarded the bus with his backpack, the driver couldn't help but inquire. "What's in that bag of yours, Leo?"

Leo chuckled and decided it was time to reveal his extraordinary hobby. He unzipped the backpack and began to assemble his hang glider right there on the bus. The other passengers watched in awe as the lightweight frame unfolded, the fabric wings stretched taut, and the control bar snapped into place. In no time, Leo had a fully functional hang glider right in the middle of the bus.

The bus erupted into applause and cheers, and even the normally stern-faced bus driver couldn't help but crack a smile. Leo explained that he designed the hang glider to be compact enough to fit on public transportation, allowing him to travel from his city apartment to the flying launch site without any hassle. His fellow passengers were amazed by his ingenuity and admired his dedication to his passion.

From that day on, Leo's hang glider adventures became a source of inspiration and entertainment for the entire city. People started recognizing him not just as a hang glider pilot but as a symbol of creativity and determination. He became a local legend, and his story spread far and wide through word of mouth and social media.

As time went on, Leo decided to take his invention to the next level. He designed a special attachment for his hang glider backpack that transformed it into a sleek, lightweight wagon with large, all-terrain wheels. This way, he could pull his hang glider with ease as he walked from the bus stop to the launch site.

One sunny afternoon, Leo set out on his usual journey, this time with his hang glider wagon in tow. As he walked through the city streets, people couldn't help but stop and stare. Children pointed and waved, and adults smiled and nodded in admiration. Leo was no longer just a hang glider pilot; he had become a symbol of innovation and the human spirit's unyielding quest for freedom.

At the launch site, Leo's fellow hang gliders would gather to watch in amazement as he effortlessly converted his wagon into a hang glider, soared into the sky, and performed breathtaking aerial maneuvers. The city below served as a mesmerizing backdrop, with its towering buildings and winding streets.

Leo's story soon caught the attention of the local media. He was invited to talk shows, featured in newspapers, and even had a short documentary made about his unique journey. But Leo remained humble throughout, emphasizing that his invention was a testament to the power of passion and the human capacity for innovation.

His hang gliding adventures also inspired others to pursue their dreams, no matter how unconventional they might seem. People started thinking outside the box, just as Leo had, and turned their passions into reality. The city began to buzz with creativity and innovation, and it was all thanks to one man's determination to make his dream of flying come true.

As the years went by, Leo continued to tiny-pack his hang glider, ride the city buses, and convert his backpack into a wagon. He never lost his sense of wonder, and his love for hang gliding remained as strong as ever. He had not only found a way to combine his passion with his daily life but had also inspired an entire city to dream big and chase their own aspirations.

Leo, the hang glider pilot who had once been an ordinary man with an extraordinary dream, had truly left an indelible mark on the city and its people. He had shown them that with a little creativity and a lot of determination, anything was possible. And as he soared through the sky, the wind in his hair and the city beneath him, Leo knew that he was living the dream he had cherished since childhood, and he was taking his city along for the ride.

One-Crutch Solution versus Two-Crutch Solution
it seems that a tiny-packed HG (TPHG) could find itself in a solution that uses just one crutch packing. However, spreading duty to two crutches might have some advantages also. Time will tell which of the solutions is most satisfying. Reports are welcome to help discern among the choices!

In either case, save the opportunity to have a moderate backpack and a robust chest pack, and maybe one or two chin-calf packs. Save in each case the ability to wear a helmet during bus riding and trekking or not, and the same for a fall-arrest harness. Water, food, and first-aid kit brought also. In either case convert the total gear and wing into a wagon for walking part of the trip to the launch.

Less Bulk: Carrying a single crutch may result in less bulk and weight to manage during bus rides and walking to the launch site.

Ease of Maneuvering: With only one crutch, it may be easier to navigate through crowded areas or tight spaces.

Quick Conversion: It may be quicker to convert the TPHG into a wagon with a one-crutch solution.

Two-Crutch Solution:
The two-crutch solution involves distributing the weight and support for the TPHG between two crutches or support structures. This approach can provide added stability and comfort. Here are some key considerations:

Enhanced Stability: Using two crutches can offer better stability when carrying the TPHG, especially during longer treks or uneven terrain.

Weight Distribution: Distributing the weight between two crutches may reduce strain on a single arm or shoulder.

Comfort: Pilots who prefer a more balanced load may find the two-crutch solution more comfortable for extended journeys.

Safety: Two crutches can offer redundancy in case one fails or malfunctions, adding an extra layer of safety.

Both solutions should consider the inclusion of essential gear such as a moderate backpack, chest pack, chin-calf packs, helmets, and a fall-arrest harness. Additionally, provisions for carrying water, food, and a first-aid kit are crucial for safety during hang gliding adventures.

The decision between wearing a helmet or a fall-arrest harness during bus rides and trekking depends on personal preference and comfort. Some pilots may choose to wear these safety items throughout the journey, while others may opt to put them on only when preparing for flight.

Lastly, converting the total gear and wing into a wagon for the walking part of the trip to the launch site remains a practical approach regardless of whether you choose a one-crutch or two-crutch solution. This allows for efficient transportation of the TPHG and gear over longer distances without the need for carrying everything by hand.

Ultimately, the choice between a one-crutch and a two-crutch solution depends on individual preferences, physical capabilities, and the specific conditions of each hang gliding adventure. Pilots should consider their comfort, safety, and ease of use when making this decision, and they can adapt their approach as needed for different scenarios. Reports and feedback from pilots who have tried both solutions can help in discerning which one suits their needs best.

Nudged Chat GPT to write a poem involving the above matters:

In the city's heart, a hang glider's dream,
Two paths diverge, or so it seems.
One-crutch in hand, a simple grace,
A tiny-packed glider, an airy embrace.

The single support, a swift design,
For bus and trek, it suits just fine.
With a backpack thin and a chest pack strong,
On this solo journey, we'll hum along.

But some may choose a dual embrace,
Two crutches for steadiness, space to chase.
A balance sought in the load we bear,
As we journey together, a dynamic pair.

Off the bus, we convert to a wagon's form,
The glider and gear, weathered and warm.
With wheels that turn and dreams taking flight,
In unity, we'll reach heights out of sight.

Label or mark each component if necessary for easy reassembly.

Prepare the Sail:
Accordion fold the sail to a width of 48 inches.
Wrap the folded sail around the pack of telescopic tubes. Secure it tightly with Velcro straps or similar fasteners to keep it compact.

Prepare the Telescopic Tubes:
Slide the telescopic tubes inside each other, starting with the smallest diameter tube on the inside.
Ensure that the tubes are fully collapsed and secured in their compact form.

Attach Wheels to the Package:
Using wheel connectors (brackets, screws, or other fasteners), attach two sets of wheels to the bottom of the package. Place the wheels towards the rear of the package to provide support.

Secure the Components:
Use straps, Velcro ties, or other fasteners to secure the components within the package, ensuring that everything is tightly packed.

Transport with the Wheels:
When you're on the bus, carry the package upright with your chest hugging it, ensuring it doesn't obstruct other passengers.
Once off the bus, simply tilt the package onto the wheels, and you can now roll it like a wagon to the launch site.

Arrival at Launch Site:
Carefully remove the hang glider components from the package.
Prepare the hang glider for assembly and flight according to manufacturer instructions.
By attaching wheels to the packed hang glider package, you can easily create a makeshift wagon for convenient transport to the launch site without the need for additional towing equipment. Just ensure that the wheels are securely attached, and the package is balanced for stability during transport.

One research project: Make a mock package of 2"x12"x60".

Have the package be a simple paper-wrapped low-density Styrofoam block. Have the paper clean, white. Go to major car dealers and note to the salesperson that to buy a car, I need to first check if this foam block can fit in the back seat area, perhaps at one of several diagonals, if needed. Make note of the cars that can receive the package and make note of any model that cannot receive such package. Per car make where fit just misses, how much of the 60" hangs out the window or hangs out the trunk? The overhang might be fully legal. Hitchhiking? Know your stuff!

Various positions inside a car to try and make note:
Across laps squared up?
Flatish but diagonal?
Narrow and diagonal behind driver in sedans?
Passenger seat reclined; package as substitute for passenger using foot room, but inclined some, perhaps.
Trunk? Diagonally in trunk? Opened rear seat to trunk?

This note has as focus the connection of a leading edge tube with the spreader or sweep strut tube.
Several means of making the join have shown in hang glider history. Reviewing what others have done could take a while, but the journey may have value. Lash it, bolt it, insert it, weld it, channel it, ... During flight the join is wanted to be fixed; or perhaps someone wants the join to move for shape morphing. Security is important. Perhaps one wants the join to be rotatable as part of a folding process for packing the wing for storage. Keep the join in all phases of handling or dismantle the join. Choices faces various conjured needs. Etc.

Well, the TPHG movement (tiny-packed hang glider) will no doubt frequently be facing the need to design, build, and operate a joining scheme: join a leading edge tube with a spreader or sweep strut. All are invited to tell their stories on this matter.

Hereon a particular scheme will be explored; I am seeking yet a name for the scheme. The scheme involves a rooted line and a lashing, both of which undo for packing away the wing for transporting the wing back home after a flight session. Assembly of the wing at flight site will involve rooting a line on the LE tube, having the other end of the line capture the spreader tube; then a removable lashing is set to cause the two tubes to hug each other. Two assistive parts: line and lashing material.

Pause: I fed my rough notes above to Chat GPT as I asked it to clean it up. I will now share that clean-up effort:

This note focuses on the connection of a leading-edge tube with a spreader or sweep strut tube. Over time, hang glider enthusiasts have employed various methods for this connection, ranging from lashing, bolting, inserting, welding, to channeling, among others. These choices hinge on factors like the desire for a fixed or flexible joint during flight, security, the need for rotational capability for wing folding, and ease of handling or disassembly.

As part of the TPHG (Tiny-Packed Hang Glider) movement, which frequently involves designing compact hang gliders, there's a recurring need to develop effective joining schemes for connecting leading edge tubes with spreader or sweep struts. We welcome contributions and stories from anyone with experience in this area.

In this context, we will explore a specific joining scheme that utilizes a rooted line and a removable lashing. This scheme enables quick assembly at the flight site by attaching one end of the line to the leading-edge tube and capturing the spreader tube with the other end. A removable lashing is then applied to secure the two tubes together. This scheme simplifies disassembly for transport, relying on just two essential components: the line and the lashing material. If you have any suggestions for a name for this scheme, please feel free to share them.

== To continue about the particular scheme. How to "root" or anchor the assistive line? How to attach the other end of the line to the spreader or sweep tube? And then how to design and use the assistive lashing strap? Whatever is done would need to be tested for safety reasons. Failure modes need to be discovered and then mitigated.

One root scheme being explored is to loop about an inboard shear pin's projections on the LE tube; then have the line reach along the LE tube to capture the near-tip of the outboard region of the spreader or sweep-keeping tube. The mode of capture can vary; one mode could be the kiting of an end plug via a hole about 3 inches from the outboard tip of the spreader tube. Flight forces would tension the assistive line and firmly seat the end collared plug. To stop flailing of the two joined tubes, use the other part -- the lashing strap; lash and set the lash.

Pause: I let Chat GPT have a go at cleaning up my above notes:

Continuing with the particular scheme, we delve into the crucial details of how to anchor the assistive line, attach its other end to the spreader or sweep tube, and design the effective use of the lashing strap. It's essential to emphasize that any method chosen must undergo rigorous testing for safety, with a thorough examination of potential failure modes and subsequent mitigation strategies.

One proposed anchoring scheme involves securing the assistive line inboard on the leading-edge (LE) tube. The line extends along the LE tube to an access hole located approximately 3 inches away from the end of the spreader tube. At this point, the line enters the access hole and is then attached to the collared plug situated at the end of the spreader tube. During assembly, the components may remain loosely connected until the plug is securely fastened to the line. To prevent any unwanted movement or separation of the two joined tubes, the lashing strap comes into play, effectively lashing and securely setting the connection.

One protocol on this exploration is to have the plug pre-captured and then line the assistive line from the tube tip into the interior of the tube and then out the access hole and onwards to the rooting at the shear-pin projections. Sharpening this arrangement will come via iterations during experience. At the shear pin, have the assistive line have a loop long enough to wrap the LE tube twice before reaching to the sweep-strut tip and plug. The length of the assistive line is a precision matter.

Motivations for exploring the specific scheme: no dedicated bolts, no nuts, no washers, no fittings (besides the plug). The plug helps to keep sand and dirt from the inside of the spreader/sweep keeper/crossbar. But the plug is a core part in the scheme and needs to be able to hold the tensions that will occur to tend to shear its collar; the plug will be pulled to firm its seating.

Failure modes will be discovered, some guessed, and some mitigations: capturing shear pin used in telescoping LE could come loose (a tiny strap might be used near the capture); assistive line wear and breaking (inspect and replace); plug collar shearing and wear (have adequate plug design, inspect, replace).

Letting Chat GPT have another go over my notes:

To continue discussing the particular scheme, we'll delve into the critical details of how to anchor the assistive line, attach its other end to the spreader or sweep tube, and design the effective use of the lashing strap. It's imperative to stress that any chosen method must undergo rigorous safety testing, with a comprehensive examination of potential failure modes and subsequent mitigation strategies.

One approach being explored involves pre-capturing the plug and then threading the assistive line from the tube tip into the interior of the tube and out through the access hole, ultimately connecting it to the shear-pin projections on the leading-edge (LE) tube. Refinements to this arrangement will naturally evolve through experience and iterations. At the shear pin, the assistive line forms a loop long enough to wrap around the LE tube twice before extending to the tip of the sweep strut and the plug. Precision in determining the length of the assistive line is crucial.

The motivation behind this specific scheme is to eliminate the need for dedicated bolts, nuts, washers, or additional fittings, apart from the essential plug. The plug serves a dual purpose by helping to prevent the entry of sand and dirt into the spreader/sweep keeper/crossbar while also playing a central role in the scheme's integrity. It must withstand the tensions that will naturally act upon it, tending to shear its collar. The plug will be pulled firmly to secure its seating.

As we explore this scheme further, we anticipate discovering various failure modes, some foreseeable, and others unexpected. Mitigation strategies include ensuring the secure capture of the shear pin used in the telescoping LE (consider using a tiny strap for added security), regular inspection and replacement of the assistive line to address wear and potential breakage, and the design of a robust plug with the capability to withstand shear forces and wear. Regular inspections and replacements are key to maintaining the safety and reliability of this joining scheme.

The over-join lashing is essential in this explored scheme. A webbing of quality hook-and-loop thrice wrapped might firm the join.

This note begins to examine a means to join two LEs and keel that will need testing evaluation and iterations to mitigate challenges. Call the means "Webbing Nose" (WN) for a handle. Tiny-packing is in mind as WN is considered. WN consist of a strip of heavy webbing bound to three plugs; the plugs are permanently set into the ends of the three tubes forming the nose of a HG. The webbing form vertical hinging for tiny packing where the three tubes stand side-by-side; the tubes have telescopic tubes inside. Open the telescopic situation to form the full LEs and keel. In pack, the LLE, RLE, keel stand immediately next to each other; the formed two webbing hinging straighten in pack. At assembly the WN simply opens to design sweep angle.

Pause: I let Chat GPT 3.5 have a chance to massage the above. Below is its response:

This note initiates an exploration of a method for connecting two Leading Edges (LEs) and a keel. This method will require testing, evaluation, and iterative adjustments to address potential challenges. For simplicity, we will refer to this method as "Webbing Nose" (WN). The primary consideration during the development of WN is compactness, aiming for a compact design.

WN consists of a heavy webbing strip securely attached to three plugs, which are permanently integrated into the ends of three tubes that make up the nose of a Hang Glider (HG). The webbing serves as a vertical hinge, facilitating compact packing when the three tubes are positioned side by side. These tubes contain telescopic components within them. To assemble the full Leading Edges (LEs) and keel, simply extend the telescopic tubes.

During packing, the Left Leading Edge (LLE), Right Leading Edge (RLE), and keel sit closely adjacent to each other, and the webbing hinges formed by the three tubes straighten out to achieve a compact packing configuration. During assembly, the Webbing Nose (WN) easily opens to define the desired sweep angle for the design.

Note: At packing WN is with sail separated from the tubes.
