The Department of Defense (DOD) is seeking proposals for the topic of "Advanced Enabling High-Speed Technologies" as part of the SBIR program. The research focuses on advancements in additive manufacturing techniques, materials, propulsion combined cycles, and hot structures. The objective is to deliver combat power and lethality by achieving responsiveness, intensity, and the ability to deliver munitions at range. The technology sought includes propulsion solutions using high-density, storable, and rapidly loadable propellants, as well as advancements in understanding and characterizing novel fluid dynamics for enhanced propulsion performance. The solicitation is open for Phase II proposals only, and proposers must demonstrate feasibility and potential military or commercial applications. The Phase II effort consists of a base period of 12 months and an option period of 12 months. The ultimate goal is to transition and commercialize the developed technologies for both military and commercial applications, particularly in the areas of manned or unmanned air and space platforms.
