TECHNICAL ABSTRACT ( Limit 2000 characters, approximately 200 words)
NASA has determined that it requires extremely durable, high-performance, low cost engines to meet future multi-use in-space, non-toxic, cryogenic propulsion requirements such as orbit transfer, descent, ascent and pulsing attitude control. Transpiration-cooling technology has long been considered a candidate for long-life thrust chambers but has never been deployed on a domestic rocket engine. In this program WASK Engineering, Inc. demonstrates methane transpiration cooling of an oxygen/methane thrust chamber at 260 psia chamber pressure and a range of mixture ratios up to 3.2 O/F in a 65 lbf engine assembly. Key tasks are the design and fabrication of a transpiration-cooled chamber spool section that integrates into existing hardware from an on-going USAF program and then hot fire testing it in the existing test stand. Post-test data analyses are used to anchor and refine thermal and performance algorithms in transpiration cooling models that then validate, or invalidate, transpiration cooled thrust chambers for this set of requirements.

POTENTIAL NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Extremely durable, high-performance, low cost engines to meet future multi-use in-space, non-toxic, cryogenic propulsion requirements such as orbit transfer, descent, ascent and especially pulsing attitude control.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS ( Limit 1500 characters, approximately 150 words)
Commercial space tourism missions (both axial and RCS engines), multiple USAF reusable propulsion applications, actively-cooled aero-shell and leading edge applications, and commercial heat-transfer both for cooling electronics and in process control applications.

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.
