Integrated refractory construction for sharp hypersonic leading edges

Physical Sciences Inc. (PSI) proposes to develop protective integrated tape solutions for sharp leading edges (LEs) on hypersonic vehicles to enable low drag during flight. The material system will consist of a refractory material that will be integrated directly with PSIÆs existing ceramic matrix composite system. The resulting protective layer will be dense with high temperature and low oxidation capabilities to enable shape retention during hypersonic flight. The system is integrated directly into PSIÆs composite manufacturing process, requiring no additional process steps or specialized application equipment. The composition of the layer can be functionally graded to promote maximum adhesion. Thick applications can be machined to tight tolerances without impacting underlying fiber reinforcements. During the proposed Phase I, the PSI team will demonstrate feasibility through a regime of LE fabrication, testing, and modeling efforts. During Phase II the team will fabricate ground test articles based on anticipated designs, paving the way for inclusion in operational Missile Defense Agency (MDA) vehicles.
