TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Innovative light-weight airlock technologies are required to integrate with any deep space and surface platform hosting Extra-Vehicular Activity (EVA). The CFD Research Corporation (CFDRC) team proposes an inflatable airlock structure that employs unique fabric architecture capable of delivering the lowest mass and greatest versatility of any competing design. The proposed fabric inflatable airlock design features a completely integrated air beam inter-wall to passively generate the wall stiffness required for airlock depressurization—without the mass and bulk of aluminum pressure hulls or complexity of multi-structure adaptations of competing inflatable habitat architectures. The design is a modification of Thin Red Line Aerospace's (TRLA) patented Ultra High Performance Pressure Vessel (UHPV), the only fabric pressure vessel design with fully determinate load paths which allows for true mass optimization. This unique architecture utilizes a matrix of braided fiber tendons to contain the structure's global pressure loads. The underlying woven fabric and gas barrier envelopes are thereby only exposed to minimal local shell loads where they bulge outwards between adjacent tendons. Working in pure tension in the absence of load coupling, the tendon array architecture has been shown to be statically determinate and auto-stabilizing under extreme deflection. The proposed fabric inflatable airlock stows compactly for transport to the habitat further reducing logistic costs.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
The proposed inflatable airlock design will have immediate application in expanding the utility of any human space exploration architecture while benefiting from system cost and payload volume reduction. The proposed technology will find direct application within NASA and industry in ongoing inflatable structures programs such as lunar surface habitation architecture and rover vehicles. Other NASA applications include habitats, large-scale space hangars for on-orbit assembly, design and analysis of space-based inflatable structures such as telescopes, inflatable aerodynamic decelerators, antenna reflectors, cryogenic propellant tanks, debris shields, rescue vehicles, and barometric chambers

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA commercial applications include many potential venues including underwater habitats, deep sea emergency escape systems (submarine), portable storage tanks for oil transport, high altitude air ships, aerostats, compressed air energy storage, remote fuel depot stations, remote water storage tanks for forest fire control, deep space antenna reflectors for ground stations, antenna radomes, emergency shelters, and troop shelters with integrated ballistic protection.
