Abstract
A process for the production of a vessel for high pressure gas, particularly helium, for a space launcher or for a satellite with a short lifetime. The process includes the step of producing an internal skin of a plastic material selected from polyethylene and crystallized polyamide. The process also includes winding a reinforcement of fibers and resins around the internal skin, and then providing the obtained vessel with the necessary conduits and control valves.
Claims9
Vessel for high pressure gas comprising an internal skin (2) of a plastic material covered with a reinforcing winding (3), wherein said vessel has a mean permeability of the order of 1.16×10−13 Nm2/bar/s for a utilization pressure greater than half the bursting pressure.
