The Department of Defense, specifically the United States Air Force (USAF), is seeking innovative solutions for the development of accelerated heat transfer models for Rotating Detonation Rocket Engines (RDRE) under the Small Business Innovation Research (SBIR) program. The primary objective is to create computationally efficient models that can predict heat transfer in 3D time-resolved simulations, addressing the challenges posed by the high-temperature environment and complex flow dynamics within RDREs. This technology is crucial for enhancing the performance and cost-effectiveness of liquid rocket engines, which have significant military and dual-use applications, including orbit transfer vehicles. Interested parties should note that the solicitation is currently closed, with the application due date having been October 23, 2024, and further details can be found at the official DOD SBIR/STTR website.
