TECHNICAL ABSTRACT (Limit 2000 characters, approximately 200 words)
The proposed effort aims to evaluate the feasibility of using transpiration-cooled Titanium as the primary material in small-scale thrust chambers for in-space chemical propulsion applications in the 25-5,000lbf thrust class. This approach would allow for bipropellant thrust chambers that are almost 10-times lighter and significantly less expensive than current state-of-the-art radiatively-cooled refractory metal (e.g. Iridium / Rhenium) systems. In addition, since they are actively cooled, the proposed approach will allow for higher chamber pressures, thereby providing further reductions in thruster size and mass for performance improvement.

POTENTIAL NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
NASA applications for the proposed systems are expected to include maneuvering or orbit transfer in science and exploration missions, RCS thrusters for in-space maneuvering, first stage and upper stage propulsion for nano-sat launch vehicles, and planetary lander ascent / descent engines.

POTENTIAL NON-NASA COMMERCIAL APPLICATIONS (Limit 1500 characters, approximately 150 words)
Potential non-NASA applications are expected to include maneuvering or orbit transfer thrusters for DoD spacecraft (particularly those for low-cost and responsive access to space). Further non-governmental applications could include lightweight apogee-kick motors for commercial satellites as well as use by integrators of small space propulsion systems for commercial missions and small-scale reusable vehicle developers.
