A novel design and construction method for an inflatable, rigidizable wing for a terrestrial or planetary flying vehicle. The wing is caused to deploy from an initially packed condition and to assume its functional shape by means of an inflation gas. After inflation, the wing is rigidized by any of several means, such that the inflation gas is no longer required. The composite wing is fabricated from a base reinforcement material, often a fabric, which is coated with a polymer resin that hardens when exposed to a curing mechanism. Several activation mechanisms exist by which to initiate rigidization of such a structure, including elevated temperature, ultraviolet light, and chemical constituents of the inflation gas. The resultant wing has fundamental advantages compared to existing inflatable wings, including improved stiffness, and reduced susceptibility to structural failure in response to puncture.

A method of fabricating an articulated joint for a pressure vessel, especially a pressure suit, by separately forming a structural fabric and a gas barrier layer into a series of alternating peaks and valleys. The structural fabric can be formed into the three dimensional shape by patterning or heat shrinkage. The resulting articulated joint, pressure vessels and pressurized suits are also described.

A novel Adjustable Pressure Suit Torso manufactured from a combination of rigid metal or composite components and flexible textile and membrane materials has been developed. It offers many advantages over primarily soft or rigid approaches to the construction of torso components used in pressure suits such as space suits or high-altitude flight suits. The Adjustable Pressure Suit Torso comprises a series of rigid rings as openings for the limbs and head to extend into from the torso, rigid brackets that are fixed between the rigid ring components, and flexible materials that span the area between the rings to act as a pressure vessel. The brackets have specific sizes and can be easily exchanged to resize the torso to fit a wide range of users. The loading imparted on the pressure suit from operation or pressurization is reacted by the rigid components. The structure can be made to be lightweight and safe from catastrophic depressurization from punctures or tears because the flexible materials are not highly stressed. The technology can be used on a wide variety of pressure suit configurations including those that are joined at the waist, or enter through a hatch on the back, and can be applied to the upper and or lower torso areas of the body. The primary advantages of the Adjustable Pressure Suit Torso over conventional rigid or soft torsos used in pressure suits include improved fit which improved mobility and performance of the wearer, a reduced number of sizes required to fit a large population which reduces logistical burden, lower cost to design and produce, improved safety, improves long-term wearer health by reducing shoulder injuries form donning/doffing and operation, reduced mass, and reduced life-cycle cost.
