Completed TRL 2 (started at 1, targeting 4)
The Combustion Modeling Technical Challenge develops new computational models that more accurately predict detailed chemical reactions associated with jet fuel combustion. These new models will lead to the design of more fuel-efficient jet engines and allow the relative merits of different alternative fuels to be assessed. Near-term goals include the accurate prediction of lean flame blowout and soot emissions as a function of changes in fuel composition.
Improved models of chemically reacting flows found in jet engines including advances in chemistry, spray, and turbulent combustion models will enable engine designs offering improved fuel efficiency and reduced NOx emissions. Advances in model accuracy and understanding of combustion processes will accelerate certification and use of promising alternative fuels, in collaboration with the National Jet Fuels Combustion Program (NJFCP).
Listed on TechPort itself — the most direct way to ask about this specific project.
This is early/mid-stage (TRL 2) — 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.
