Advanced Airlock Concept Studies for Exploration Surface Systems 2006-01-2234
This paper presents results of advanced airlock concept studies conducted at the NASA Johnson Space Center in support of exploration surface systems, such as lunar lander airlocks and other advanced vehicle airlocks. The studies include preliminary requirements for advanced airlocks, and rationale for using the rear-entry space suit as the basic advanced suit design to be accommodated by the airlocks. The studies also present rationale for minimum volume airlocks and gas reclamation methods needed for long duration missions. Another study shows conceptual designs for single person airlocks, dual person airlocks, and multi-person airlocks, along with associated benefits and disadvantages of each. A test and selection methodology is also discussed for future airlock development.
