An aerospace vessel including a fuselage, a means for causing the fuselage to fly coupled to the fuselage, and an environmental control system within the fuselage. The environmental control system includes a duct made of closed cell thermoplastic foam, such as polyvinylidene fluoride foam.

A process for fabricating a three-dimensional, multi-layered fabric product with a moisture barrier is provided. A partially seamed inner lining fabric assembly having at least a two-dimensional shape is laminated with a membrane barrier film having flaps left un-laminated to cover at least one seam. The inner lining fabric assembly is further seamed and flaps of the of the membrane barrier film overlapped into contact with each other and sealed to provide a continuous moisture barrier. A process for fabricating a stretchable section of a garment with a moisture barrier is also provided. At least a section of a garment is formed from fibers arranged in a pattern having a direction of stretch in one direction and a three-dimensional surface texture such that a portion of the fibers protrude above another portion of the fibers. The stretchable section is stretched in the direction of stretch. Segments of a membrane barrier film are adhered to an outer edge of the protruding portion of the fibers while the section is stretched in the direction of stretch, leaving intermediate segments of the barrier film free from adherence to the section. In this way, the intermediate segments of the membrane barrier film include slack that folds up to form ruches when the section is in a relaxed state.

Membrane elements that use multiple membrane leaves may have a limited total active membrane area due to an increased diameter at the ends of the element. Membrane leaves may comprise a permeate carrier positioned between one or more membrane sheets. Adhesive may be used to seal one or more edges of the membrane leaf. The membrane sheets, permeate carrier and the adhesive contribute to the thickness of the edges of the membrane leaf and the diameter at the ends of the element. A reduced thickness of the edges of the permeate carrier may reduce the diameter at the ends of an element. Another permeate carrier sheet may also be used that is distanced from at least one edge of the membrane sheet so the permeate carrier sheet does not contribute towards the increased diameter at the ends of the element.

The present invention provides an inflatable trampoline. The inflatable trampoline includes an inflatable frame, a connecting sheet and an elastic assembly. The inflatable frame includes a plurality of first sheets and a plurality of second sheets; a fabric layer is arranged within the first sheet, two second sheets are respectively welded to two edges of the first sheet, and two adjacent second sheets are welded to each other; the first sheet and the second sheet form the inflatable frame, and an inflatable cavity is provided within the inflatable frame. An edge of the connecting sheet is welded to an upper surface of the inflatable frame, and an opening is provided in a middle of the connecting sheet. The elastic assembly is located in the opening, and the elastic assembly is connected to the connecting sheet through a plurality of first connecting members.
