Multidisciplinary design, analysis, and optimization (MDAO) is a critical enabling technology for the design of complex systems such as naval aircraft. Using high-performance computing and modern analysis codes, many aspects of naval aircraft, and other, systems can be accurately modeled. However, the generation of the meshes analysis codes need as input is overly time consuming, while it takes su ...

Additive Manufacturing (AM) is a modern and increasingly popular manufacturing process for metallic components, but it suffers from well-known problems of inconsistent quality of the finished product. The US Navy is interested in addressing this problem by developing a digital twin-based machine control tool for in-situ AM process monitoring and healing. Therefore, sensor fusion monitoring, machin ...

This effort aims to deliver a novel ultra-thin flat lens optics with a large aperture and active zoom capabilities that is based on metasurface metamaterial technology while being mindful of the size, weight, power, and cost. The proposed approach will achieve zoom through a tunable metalens system that operates using micro-electromechanical systems (MEMS) within a small and lightweight package fo ...

We propose to develop and transition CodeSurgeon: an adaptable, AI-guided, full-stack debloating system. CodeSurgeon is innovative and unique in the field because it produces high-quality debloated programs with improved security posture that are safe, reliable, and sound. Following the lessons learned from a broad comparative evaluation of debloating tools conducted by the PI , CodeSurgeon will i ...

The goal of this topic is to produce low density and high stiffness space mirrors. 3DFlexible has developed a new additive manufacturing process which incorporates fabricating parts via layer-by-layer printing using glass bubble paste (GBP) and sintering the parts into cellular solids. Cellular solids are structures that are composed of a network of solid struts forming the edges and faces of cell ...

Additive manufacturing (AM) increases the speed and flexibility of production and enables traditional part concatenation for advanced manufacturing capabilities. The ability for U.S. manufacturers to 3D-print advanced components in-house reduces reliance on traditional subtractive supply chains and bolsters national security readiness. While AM affords unique flexibility in design for manufacturab ...

The proposed system consists of two types of antenna arrays, a low frequency vector sensor for coverage below 300 MHz and a high frequency circularly dispersed array with coverage to 20+ GHz. Both arrays are omni directional  with enhanced response across their entire operating frequency range. Both antenna arrays can handle horizontal, vertical or elliptically polarized waves. The low frequency ...

The proposed modeling and simulation approach aims to bridge the gap in terms of accuracy and cost between 3D Computational Fluid Dynamics solvers and currently available design tools. The Hypersonic Flow Analysis Tool (HyperFAT) will combine 3D Euler simulations using a higher-order immersed boundary method with viscous corrections to account for boundary layers. The use of the immersed boundary ...

Titan Systems proposes a systems approach to solving the "ALT-PNT" problem for navigation in GPS-denied operating areas.  This includes use of a Proliferated Low Earth Orbit (PLEO) SATCOM system, miniaturized Signal of Opportunity geo-location receivers, a wideband SOO antenna, a Honeywell Embedded GPS Inertial - Modernization  (EGI-M) unit, and a Magnetic Variation sensor input to "bound" the f ...

A novel approach to moving Minotaur data (with its unique data model) across Line-of-Sight networks using UHF radios and across SATCOM networks using Proliferated Low Earth Orbit (PLEO), such as, emergent Starlink, MUOS for IP based low data rated links, and emergent S-Band.  The approach includes development of API translators for Minotaur data model to UHF radio data protocols.
