High Chamber Pressure, Light Weight Thrusters
Completed
TRL 4 (started at 3, targeting 4)
Description
The performance liquid propellant engines can be significantly improved by increasing both combustion temperature and pressure and reducing engine weight. State of the art Bi-propellant engines are metallic; the highest temperature combustion chambers are made of iridium/rhenium metals. Utilizing carbon-carbon composites for thrust chamber structures can reduce component weight by as much as 90%. Unfortunately carbon composites suffer from unacceptably high oxidation rates. Lining carbon-carbon chambers with a thin layer of iridium or iridium/rhenium is an innovative way to provide the oxidation barrier necessary to enable the use of carbon-carbon composites. This proposal evaluates using metal-lined carbon-carbon to produce high pressure, light weight thrust chambers.
Benefits
Rocket nozzles for satellites and military. Metal lined carbon composite technology has applications for crucibles, heat pipes, propulsion subcomponents, x-ray targets, sputtering targets, turbines, rotors, furnaces, power generation
Mars Ascent Vehicle, Altair Ascent Module, reaction control systems, in-space propulsion, attitude control, orbit maintenance, repositioning of satellites/spacecraft, and descent/ascent engines, nuclear power/propulsion, microgravity containment crucibles and cartridges.

How to get involved
This is early/mid-stage (TRL 4) — the most realistic path in is NASA SBIR/STTR, which funds small businesses and research institutions to develop technology aligned with NASA's needs (equity-free, phased funding). Check whether a current SBIR/STTR solicitation topic overlaps with this project's technology area, or contact the project directly (above) to ask.
None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
