NASA Headquarters is inviting proposals for the Commercial Supersonic Technology (CST) Project, specifically seeking innovative designs for a fuel injector that meets low NOx emissions standards for supersonic aircraft. The objective is to develop a state-of-the-art fuel injector design concept and fabrication for testing at NASA Glenn Research Center, aligning with the agency's Aeronautics Research Mission Directorate's goals for high-speed aircraft innovation. This initiative is crucial for advancing supersonic flight technology, targeting aircraft entry into service around 2035. Proposals are due by May 31, 2024, and interested applicants can reach out to Jennifer Klettlinger at j.klettlinger@nasa.gov for further inquiries. More details can be found at the provided NSPIRES link.
