An inflatable and rigidizable structure for use as a habitat or a load
bearing structure is disclosed. The structure consists of an outer wall
and an inner wall defining a containment member and a bladder. The
bladder is pressurized to erect the structure from an initially collapsed
state. The containment member is subsequently injected with rigidizable
fluid through an arrangement of injection ports. Exhaust gases from the
curing rigidizable fluid are vented through an arrangement of exhaust
ports. The rate of erection can be controlled by frictional engagement
with a container or by using a tether. A method for fabricating a tubular
structure is disclosed.
