Wing5-Mx? spar-case inversion and detail workWork to be done on the yellow too-heavy spar-case in order to explore getting non-bladder airtightness; a bladder may still also be explored for this too-heavy spar care:
Tiny bead of silicon to seal just next to the first line of stitching.
Single-sided tape over the cured silicon
Heat seal the edge of the flange in the seam allowance. Explore my available tools: soldering iron, hot-knife, clothes iron. Move from craft immaturity to more maturity. Note needed tools.
Closing the two ends of the tube. The ends will be closed to a flat straight line of about 24" in length. The design of the closing is to permit opening when wanted (but not each session, but only when special work on the interior of the tube is needed). An interior elastic foam stick will be squeezed by two sticks of wood or aluminum or carbon fiber; the two sticks will be pulled together squeezing the two layers of the tube and a flange of the elastic-foam stick. The pulling will be achieved by some method, perhaps among: a series of bolts, a series of string knotted loops, a string or wire stitching through a series of holes, ... The pulling or clamping will resist the inflation pressures. The tip rib will be tied to the tube-end-closing complex. I want to avoid heavy-sewing closing of the tube end, because cutting all that stitching to get back inside the tube would not be fun.
Invert a long tube. How? Methods? Wrestling...
Working on a long seam of a long fabric tube?Sealing a sewn seam via various methods: Silicon? One-sided tape? Can a double-fabric seam be fused? Would'a could'a?
First experience with supplier was deliberately kept simple, short, easy; a simple sewn seam was asked and given. But in self-shop, fusion or double-sided bonding tape might have occurred for the seam. Remedial work will give lessons. The flange of material of the seam of the long tube may be silicon beaded, one-sided tape; the very edge of the flange might be heat sealed manually.
Not having a 20-ft cantilever tongue on which to set out the long tube (and not caring to build and store such jig), a short 4-ft jig will be moved along the tube's interior on a table or floor; the 4-ft jig or interior-of-tube mandrel will provide an opportunity to work on the tube's interior or exterior (invert tube for choice of working surface of the tube). The assistive mandrel will be smaller than the interior of the tube. the tube drapes over the mandrel; tension in the tube material may be obtained by use of clamps in various ways. A cord might pull the interior mandrel while the tube is stayed oppositely.
The involved experiences and gained lessons will enable the long-term wing-iteration production. It is anticipated that scores of HG wings will be built in order to find and materialize satisfactory Wing5 designs. Several branches of technologies are anticipated to reach satisfactory Wing5s.
Core global technologies to explore for small-pack air-framed HG: Splinted air-beam for spar, else other framing (this is the focus of M1 of Wing5 from my shop; other people may be working with a different technology for Wing5 or Wing4 or Wing3 or Wing2 or Wing1 solutions; others are welcome to post their progress on their Wing5, Wing4, Wing3, etc. HG wings) The "Wing4" has tote member of at most 4 feet. Etc. Wing1 allows that a diagonal of cube of 1 ft is longer than 1 ft.
Deployable trusses
Coilable-shells
Tensegrity framing
High-end telescopic beams in bow-wing format
Standard framing with couplers, but no inflation members
Inflatable without stick members. All beams are positively inflatables. (Distinguish from collapsible ram-air-inflated chambers as found in SS or DS PGs and Jalbert parafoil kites, gliders, parachutes)
Memory forms (press closed; remove pressure and the structure returns)
Bucket of self-assembling programmed widgets? Call out: "Assemble!" Watch the widgets assemble themselves into a HG. "Pack!" Watch the widgets work themselves down into the bucket.
Ambient growth (go to flight sight; grow the wing from site-ambient materials; leave those materials at the site; carry no wing back-and-forth from home)
Stored wings; use no car, bus, train, or truck to transport a HG Many clubs have this sort of arrangement for some wings.
The company at Dockweiler has a steel freight container that holds very many wings; those wings are not available when the company is closed; that company's container is not available to recreating pilots, except when the company makes a decision otherwise. Liabilities are involved in having storage containers at sites; the costs to have some storage compete with the costs of toting wings from homes.
Storing wings close to a flight site, perhaps close enough where a foot-cart would succeed in getting the wing to launch.
Hiding parts of a HG risks loss from theft, corrosion, trespassing fines, ... Hiding just long sticks at site, but carrying other parts from home? Hide sticks as pseudo-fence beams; take sail from home; grab the pseudo-fence posts to finish the frame of the HG? Telescoping beams .... hidden in pseudo flag pole at or near the flight site? Instead of a wire fence, have a thick fence with storage room inside the fence interior. Instead of the the block wall, have a hollow wall; store wings inside the follows; lock the wall cap. Store HGs inside hollow traffic curbs.
Look to walk-near-flight-site neighborhoods and look for wing-storage opportunities shared. Rental spaces?
Live walkably near flight site. Live at the launch site?
Power fly the wing from home to HG launch site? Ever-up HG wing?
Storing an object worth thousands of dollars without appropriate guards forms a magnet for thieves.
