PermiAM: Engineered Porosity In-Situ with Fully Dense AM Structure

This work answers the questions and needs of Focus Area 21 Subtopic Z9.01 for small launch vehicle technologies by providing affordable launch architecture, as propulsion systems are the highest cost subsystem for rocket development and PermiAM will enable a large savings for main propulsion system engine development. Part of the work performed in this SBIR will help in determine the potential savings for future engine development programs, currently projected at 10x for injector build cost savings which require face cooling. PermiAM will enable increased design simplicity for AM injectors and reduced development costs through improved face cooling and improved combustion stability. A full scale proof of concept ground test will be demonstrated by the end of Phase II, with the subscale demonstration during Phase I to meet the subtopic requirements.
