If 50 pounds is your target weight and your suspending the weigh directly below the center of your arch. Would it make any sense to move to multiple inner cells? Iknow there would be a weight trade off, but wouldn't multiple inner cells be: 1). Easier to buy/manufacture? 2). Redundent achitecture and therefore advantagous to surviving partcial failure? 3). Better at supporting weight than a single cell? If I could ask a question. If 50 pounds is your target weight and your suspending the weigh directly below the center of your arch.

The trick for a very ridged inflated structure is to have a no stretch outer shell and an over sized inner cell. This is just our test material. We want to get to a 0.4 oz per yard material.

Are these materials to heavy for your air ribs? I wish you the best of success in your float to space. My inflatable canoe body is made of vinyl overlaid with nylon and is designed for 1.5 psi.

We made an airbeam arch that will support a 50 pound suspended load when it's at 2.0 psi. A balloon will pop around 0.2 psi.

If you put 2 psi into a plastic bag, would it pop? How stiff would the rib be at that pressure? How much is 2 psi in real terms? If you put 2 psi into a plastic bag, would it pop?
