NASA SBIR 01-1 Solicitation

FORM 9B - PROPOSAL SUMMARY


PROPOSAL NUMBER: B3.06-8680 (For NASA Use Only - Chron: 013319 )
PROPOSAL TITLE:
Environmental Control Subsystems for Hyperbaric Chambers

TECHNICAL ABSTRACT (LIMIT 200 WORDS)
NASA is currently developing an on-board hyperbaric chamber to treat decompression sickness during long-term space missions. The prototype pressure vessel is already complete and Mainstream is developing a pressurization subsystem that also addresses breathing gas delivery (oxygen generation) through a current SBIR effort. An environmental control subsystem (ECS) is desperately needed to perform thermal, moisture, carbon dioxide, particulate, and volatilized hydrocarbon control and monitoring in the hyperbaric chamber. In Phase I, Mainstream will complete the preliminary design of the ECS and demonstrate active thermal control with a laboratory prototype. Mainstream's highly innovative design will improve performance by 150-200% and reliability by 470% over current space-based heat pumps. Component size, weight, and power will be demonstrated. In Phase II, the entire ECS will be fabricated, integrated with Mainstream's pressurization and oxygen delivery subsystems, and life tested. The overall result of this program will be system hardware ready for flight-approval.

POTENTIAL COMMERCIAL APPLICATIONS
Hyperbaric chamber therapy is the "Gold Standard" treatment for both altitude and diving decompression sickness. Several NASA operations including B-57 flight program, standard flight activities, NBL activities, and altitude chamber activities pose risk of decompression sickness. While fixed chamber facilities exist, some critical operations such as extra-vehicular activities (shuttle and ISS) and non-CONUS operation (Russian Hydrolab and Soyuz/ACRV landing sites) will require portable hyperbaric systems. The U.S. military has expressed interest in portable hyperbaric chambers for U.S. Navy submarine rescue, salvage operations, and SEALS, as well as U.S. Air Force high-altitude flight operations. Civilian applications include commercial diving operations and recreational diving (DAN). NASA estimates the total need for 100-200 hyperbaric chambers annually.
