Note about using stuffers in some DS HGs aiming to solve theme solutions: consider a loop where the loop of string stays with the sail sections. The loop enters the sail in two places. In the interior of the wing during assembly, the loop is mostly inside the wing for looping about inserted long stuffers that will force camber. Once the wing is assembled almost completely, then the part of the loop that is exited through eyelets in front of the leading edge can then be pulled to bring the stuffer snug to the leading edge; a line stop may cinch the hold; then adhesive tape might secure the loop's excess line to the aerodynamic quiet zone of the leading edge in order to lower the possible drag of excess string out in front of the leading edge.

Note about a method to give DS camber: have two opposing short battens of variable stiffness, one in upper skin sail and one in lower skin sail. The lower pocketed batten will have a hole in its center; and a small tethered cap will be near the hole. Poke a CF small tube through the hole and press the penetrating tube against the upper batten where a small toroidal receiving mound will be felt by the person assembling the hang glider. Then place the tethered cap on the lower end of the penetrating tube. This will force camber in the wing at that station. Do similarly at many stations. The method offers means to vary camber when all parts are designed just right. Variations on this method could be explored.

[JoeF]

More about former post matter:
The two opposing battens may vary greatly from each other to get different shaping results. An an individual batten may be made with variations along its chordwise material to achieve various effects. E.g., consider a top batten to be tapered or feathered to soften the rate of curvature when pressed while the opposing bottom batten could be stiff compared to the upper batten in order to flatten lower sail alteration when the pressing tube is set. The poking tube could be pressed and set in position by a small tethered cap; varying the length of the poking tube or varying the tethers of the position-setting cap may result in variations in the effected camber. Battens may be replaced varied battens for more change options. Battens could be wide or very wide. Many experiments await. The scheme allows full separable disassembly for high density packing for transport. By careful choices the upper camber could be very different from the lower camber.

========================
Suppose SS, not DS? The above scheme may still be explored by having taut lower chordwise lines from rear spar LE spar; then set the poker tube on the line while the upper end of the poker tube presses the batten set in the single sail.

The present noted scheme is a type of "stuffing" to help form airfoils. The poking tube is the stuffer in this scheme.

Note: Explore the possible special advantages that may occur when the "batten" is broad spanwise and is pressed by several pokers.

Note how battens can be taken out of sail pockets, how poker tube is separable, how operating the scheme is from the underside of the wing, and how great the variability is to achieve something among infinite options (though we have only finite options that could ever be tried)

Notice that batten pockets may be long or short and may be positioned anywhere on the wing covering.
Notice that poker tubes may be short or longer.

Notice that a poker tube could be V formed and connected with a control line; pull on the hinge part of the poker V and control the aerodynamics of the wing.

Rhombus calculator
For some possible solutions, this calculator might come in handy.

===========================================
Some development notes:
Spar couplers might pay for themselves by giving about 10 sq. ft sail area in one consideration.
Couplers might ease the burdens of what happens at the ends of some of the spar segments.
With spar couplers, still consider having telelescopic spar-segment sets.
Couplers might be stacked in pack or carried separate from main long pack.
If couplers are carried separate from main long pack, then consider letting the interior of the couplers hold pokers and line sets.
Spar couplers might simplify rigging opportunities.

Chat AI session:

Iterations in the design of a politely carriable packed hang glider are elements of a countable infinity of iterations. Some of the designs might be satisfactory to human A. There is no assurance that a satisfactory design will be discoverable in an A's lifetime.

ChatGPT
Your observation about the design process for a politely carriable packed hang glider brings up an interesting point about the nature of iterative design and the potential for discovering satisfactory solutions within a finite timeframe.

Countable Infinity of Design Iterations
Iterative Design:

The process of designing a hang glider involves numerous iterations, where each iteration might involve changes in materials, structure, weight, size, and other factors.
Each iteration represents a step in the exploration of a potentially vast design space.
Countable Infinity:

The number of possible design iterations can be considered countably infinite if we assume discrete changes and improvements.
This means that, theoretically, there is an infinite sequence of designs that could be tested and evaluated.

Satisfactory Designs

Satisfactory Design Criteria:

A design is considered satisfactory if it meets the criteria set by human A, such as safety, portability, ease of use, cost, and performance.
Different individuals might have different criteria for what makes a design satisfactory, leading to subjective judgments.
Discovery within a Lifetime:

Given the countable infinity of possible designs, there is no guarantee that a satisfactory design will be discovered within a finite amount of time, such as human A's lifetime.
The process of evaluating each design takes time, and with an infinite number of possibilities, the time required to find a satisfactory design could exceed a human lifespan.

Philosophical and Practical Implications
Philosophical Perspective:

This scenario highlights the limitations of human effort and time when faced with an infinite number of possibilities.
It underscores the uncertainty inherent in processes that involve exploration and discovery within an infinite or extremely large design space.
Practical Strategies:

To increase the likelihood of discovering a satisfactory design within a finite time, human A could employ strategies such as:
Heuristic Methods: Using experience and rules of thumb to guide the design process and focus on more promising areas of the design space.
Optimization Algorithms: Implementing algorithms that can efficiently search large spaces, such as genetic algorithms or simulated annealing.
Collaborative Efforts: Engaging multiple designers or using crowdsourcing to explore more design iterations in parallel.
Prototyping and Testing: Rapidly prototyping and testing designs to quickly eliminate less promising iterations.

Conclusion
Your insight into the design process reveals a fundamental challenge when dealing with an infinite or extremely large number of possibilities:

Mathematical Reality: The countable infinity of possible designs means that, in theory, there is no upper limit to the number of iterations that could be explored.

Practical Limitation: The finite nature of human time and resources means that discovering a satisfactory design within a lifetime is not assured.
Strategic Approaches: Employing efficient search strategies, leveraging experience, and optimizing the design process can increase the chances of finding a satisfactory design within a reasonable timeframe.
This reflection highlights the balance between theoretical possibilities and practical constraints, emphasizing the importance of strategic approaches in tackling complex design challenges.

In one exploration:
Strut bracket joins spar coupler firmly but without spar coupler circumferential tightness, but rather a looseness Teflonized surface lets non-twist of the spar coupler. Strut bracket LE has T-like projection for basing four loops (the ends of the four stay lines (land, fly, planar diagonals (2). An elastic ring snugs the loops; twice capture the T with the ring elastic: capture, wrap spar coupler, capture. A Teflonized stop on the spar coupler prevents the struct bracket from sliding keelwise.

Strut bracket design allows gaining some chord length and consequent wing area. A similar gain in the spar coupler along with the gain possible in the strut bracket could provide a very substantial gain in wing area. Toted pack length does not change by having these gains. One possible instantiation counts 8 spar couplers and 12 strut braces while keeping spar segments in telescopic packs.
