ZLIN does this,though it is only to have a continiousBlow up tubes with compressed air.

Is there a cheapest/lightest/simplest wing structure other than aluminium tube and fabric?

Often a second and third verse is added:
Every night when I go out,
The monkey's on the table,
Take a stick and knock it off,
Pop! Goes the weasel.
Up and down the City Road,
In and out the Eagle,
That's the way the money goes,
Pop! Goes the weasel.

Yes. There was also a prototype inflatable space station.Was it Goodyear that made the inflatoplane?
Heavy! A 4.5' x 22' wing will have 100 lbs in it before the plywood skin and any structure, hinges, spar caps, etc.How heavy is a foam wing covered with thin plywood ?

Yes, Goodyear built a few Inflatoplane prototypes during the 1950s and they patented Airmat construction techniques. Airmat looks like a constant-thickness version of the through-stitching process now used to manufacture inflatable stand-on-top paddle-boards. They start with two sheets of impermeable fabric, then through-stitch with thousands of light-weight threads to maintain a constant thickness ... when inflated. Current through-stitch sewing machines can only produce constant-thickness slabs, but I predict that variable-thickness will be available within the next 5 years.Was it Goodyear that made the inflatoplane?
Yes, Bigelow Aerospace was building inflatable add-ons for the International Space Station.Yes. There was also a prototype inflatable space station.
Yes. Airmat (for a aircraft wing) ---> Drop-Stitch Technology (for inflatable stand-on-top paddle-boards ---> ?..... Airmat looks like a constant-thickness version of the through-stitching process now used to manufacture inflatable stand-on-top paddle-boards. .....
Was it ever considered the use of an helium core for wings and fuselage to offset the weight of sturdy construction materials?Heavy! A 4.5' x 22' wing will have 100 lbs in it before the plywood skin and any structure, hinges, spar caps, etc.
Problem is helium leakage, Helium is Mother Natures Houdini which is why it's used for leak checkingWas it ever considered the use of an helium core for wings and fuselage to offset the weight of sturdy construction materials?
Do the math on the internal volume of said wing filled with helium and you'll find that it's only 4.5 pounds lighter than if filled with air and that ignores the volume of any structure in the wing. I'll let you do the math on the fuselage volume and resultant weight decrease and then you can decide if it's worth your while or notWas it ever considered the use of an helium core for wings and fuselage to offset the weight of sturdy construction materials?
