The Department of Defense, specifically the Navy, is seeking innovative proposals for the development of an adaptive bypass valve for Solid Fuel Ramjet (SFRJ) missiles as part of the SBIR program. The objective is to research, design, and prototype a state-of-the-art airflow bypass valve that can precisely control airflow between the inlet and combustor, thereby enhancing thrust control and combustion efficiency in supersonic flight. This technology is critical for advancing missile capabilities and may have dual-use applications in space exploration. The solicitation is currently in pre-release, with an open date of April 23, 2025, and a close date of May 21, 2025. Interested parties can find more information and submit proposals through the official SBIR website.
