Aerospace Structures and Materials is central to all naval aviation aircraft and weapons systems. It is the underlying enabling technology for the air vehicle and weapons for both manned and unmanned operations. Requirements for naval aviation platforms and weapons are often unique and more stringent than land- and sea- based systems. The need for efficient structure and materials is pervasive throughout naval air platforms and weapons systems. It is an exciting time to work in structures and materials focus area. Recent developments in experimental techniques and high-resolution imaging provides a means to relate micro-structure to performance. Understanding these relationships can lead to more efficient structures that are resistant to damage and can sustain fatigue, impact and ballistic loading. Similarly leveraging developments in multifunctional materials and structures has the potential of reducing parasitic weight in air vehicles and weapons making it more lethal. Advances in science of automation, artificial intelligence and machine learning can be used to tailor structure and fabricate it with reduced defects. Micro-manufacturing techniques can be used to design interfaces to meet targeted requirements. Enhanced analysis capabilities enable high fidelity design tools for upgraded and new guidance for efficiently sustaining the naval fleet. The program goal is to leverage these advances and develop technologies for lightweight survivable and sustainable structures that can meet the demands of the current and future needs of Navy and Marine Corp air vehicles and weapons. Concurrent to the technology objectives an equally important goal is to develop an eager and engaged workforce trained in structures and materials technologies aligned to Navy and Marine Corp needs.
Research Concentration Areas
The program has the following thrust areas: Corrosion and Fatigue of Metallic Airframe; Advanced Composites; Multifunctional Structures and Lightweight Armor. These are primarily concerned with light weighting the structure and increasing structural efficiency, survivability and sustainability. The structures and materials focus area will also support the infrastructure necessary to maintain technology superiority, while serving as a pipeline of future scientists and engineers.
