MDA15-020 MLMI Forward Conical Section of an Interceptor Body for Hypersonic Defense Systems

This proposed effort will yield a forward conical section of a full-size interceptor body for testing. A Multi-Layer Metal Insulation (MLMI) design will be utilized having outer layers of an alloy that can resist temperatures well beyond 3,000°F and inner layers of a metal that has a service temperature >800°F to provide structural support. The MLMI will be four (4) layers in total, each separated by egg crate elements. The outer two (2) layers, near the extreme hazardous flight environment, will provide thermal protection, while the inner two (2) layers will provide structure and support for the outer heat shields. This MLMI test unit will be provided along with a higher temperature subscale test sample that adds a layer of another material on the exterior to increase operating temperature.
