Technical description

Building system and materials - The basic structure takes its inspiration from the inflatable boats of nautical origin. Two different in material elements are cut and soldered into one: a thicker one for tubular sections, a thinner one for connection surfaces. No radial joints are used for the variable geometry of the structure. The cuts in the fabric are longitudinal and compensated in order to reduce the torsion on the tubolars. The pneumatic support section is internally divided into 8 independent rooms about 3,60 m long, the air pneumatic section being internally divided into 6 independent rooms about 3,10 m long.
Both of them are made of reinforced material with polyester fabric saturated by coating and calendering with mixtures of specific elastomers.
The different internal rooms allows for a constant balancing of the inflating pressure - about 0,2/0,25 bar - and contribute with their quenching effect to improve the resistance to the crashes, in particular thanks to the water filled section.
The material is resistant to any hydrocarbon and solvent. It has a limit breaking stretch of 20% and a use temperature ranging from - 40° to + 80°.
The control-valves for the inlet and the aspiration of air and water are movable and must be taken apart before the folding operations. The meteoric waters flow through passages opened in the collecting points on the cover surface.
