Chameleon Suit – A Different Paradigm for Future EVA Systems 2003-01-2445

The demands of future NASA exploration and scientific missions in space force the reevaluation of some of the basic assumptions and approaches that underlie current extravehicular activity (EVA) systems. Developing designs that can simultaneously achieve the advanced capabilities and the reductions in system mass and mission expendables targeted by NASA has proven to be a formidable challenge. The constraints of human needs, space environments, and current EVA system architectures demand technical capabilities beyond current expectations to achieve system goals.
Under NASA Institute for Advanced Concepts (NIAC) sponsorship, Hamilton Sundstrand has been studying a new system paradigm to achieve the EVA system goals. The Chameleon Suit concept employs an active pressure suit that directly interacts between human systems and space environments. This requires the application of technologies and components that are not currently available, but are rapidly becoming practical through the development of advanced materials, information technologies, and biomimetic designs in university, industry, and government laboratories.
