TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
Long-life, high-capacity cryocoolers are a critical need for future space systems utilizing stored cryogens. The cooling requirements for planetary and extraterrestrial exploration missions, Crew Exploration Vehicles, extended-life orbital transfer vehicles, and space depots will range from 10 to 50 W at temperatures between 20 and 120 K. Turbo-Brayton cryocoolers are ideal for these systems because they are lightweight, compact and very efficient at high cooling loads, in addition to their inherent attributes of high reliability; negligible vibration; long, maintenance-free lifetimes; and flexibility in integrating with spacecraft systems and instruments. To date, space-borne turbo-Brayton technology has been developed for low cooling loads. During the proposed program, Creare will develop an advanced, high efficiency turbine optimized for a high-capacity cryocooler. The advanced turbine will enable a landmark reduction in cryocooler input power and overall cooling system mass. In Phase I, we will define the requirements for a particular mission class, develop the conceptual design of a multistage cryocooler to meet these requirements, develop the preliminary design of the advanced turbine and perform proof-of-concept tests. During Phase II, we will fabricate the turbine and demonstrate its performance at prototypical operating conditions.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Advanced turbines will enable high-capacity turbo-Brayton cryocoolers that are compact, lightweight, and consume minimal power. Space applications include cryogen storage for planetary and extraterrestrial exploration missions, Crew Exploration Vehicles, extended-life orbital transfer vehicles, long-term geosynchronous missions, in-space propellant depots and extraterrestrial bases, and cooling systems for observation platforms requiring large arrays of infrared and X-ray detectors. Terrestrial applications include cooling for spaceport cryogen storage and cryogen transportation systems.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Non-NASA commercial applications include cooling for laboratory- and industrial-scale gas separation; liquefaction; cryogen storage and cryogen transportation systems; high-temperature superconducting magnets in motors and magnetic resonance imaging systems; liquid hydrogen fuel cell storage for the automotive industry; and commercial orbital transfer vehicles and satellites.

NASA's technology taxonomy has been developed by the SBIR-STTR program to disseminate awareness of proposed and awarded R/R&D in the agency. It is a listing of over 100 technologies, sorted into broad categories, of interest to NASA.
