The objective of the effort is to develop and demonstrate a persistent surveillance and early threat detection and warning system for hostile perimeters around sensitive or high value establishments. The persistent surveillance capability is in the form of a small unmanned air vehicle (UAV) which patrols a predetermined perimeter around the facility. Classification of the threat will be made by ...

The detection of objects underwater remains a difficult task. For many applications particularly marine defense operations, it is desirable to be able to identify the position of objects such as mines (buried and below the surface of the water) as well as to being able to discriminate between a rock and a mine. For many homeland security operations it is desirable to be able to monitor the movemen ...

Coded Orthogonal Frequency Division Multiplexing (COFDM) continues to be a preferred solution for wireless broadband data transfer. Currently many Commercial-Off-The-Shelf (COTS) solutions are available with a wide range of performance optimizations from low cost 802.11.g using 64 carriers to more expensive Digital Video Broadcasting - Terrestrial (DVB-T) solutions supporting over 8000 carriers. ...

The ACR led team proposes an affordable manufacturing technique for complex-geometry composite components to be used as stiffened curvilinear structural panels and variable shaped fuel and ballast tanks for Off-board surface vehicles. Through the use of its Aquapour™ and Aquacore™ water-soluble tooling materials, ACR has previously demonstrated that different composite material systems based o ...

During Phase I, 3TEX designed universal, one-piece, 3D woven fiber preforms which can be used as either a “Butt” (H) joint or as a “P” joint as needed. Composite joints were fabricated and tested, demonstrating the benefit of the integral nature of the 3D preforms. 3D stress/strain and crack propagation analysis of composite Π-joint was performed using 3D MOSAIC code. 3D displacement, st ...

Military helicopters rotors contend with rain, ice, sand, and flying debris. To prevent damage to the expensive blade protective sheaths or coatings are applied to the leading edge of the rotor blades. A 3-D woven composite sheath with high thermal conductivity fibers running through the thickness can offer the best qualities of both metal sheaths and elastomer coatings. Infused with an elastom ...

Miller Fasteners made from 2-D laminates represent the state of the art in joining CMC panels to metal frames. Despite its success, the extant Miller fastener design is limited by its construction from a laminate of 2-D fabric. The resultant fastener part has poor interlaminar shear strength, and its manufacture and application entails high machining costs and high material scrap rates. 3TEX, i ...

We propose to develop a new fiber optic switch for IRCM applications. The purpose of the phase I program is to demonstrate the feasibility of a high power 1xN (N=2-6) fiber optic switch operating in the mid IR region. By carefully optimizing each individual optical component, the optical switch will have a minimum net insertion loss of less than ~0.25dB at given laser wavelengths in the mid IR reg ...

Breault Research Organization, Inc. (BRO) proposes in Phase I to advance the design of transmitted wavefront test equipment that can be used to characterize deep concave shapes including ogives. The approach is based, in part, on interferometric concepts that have been used for decades, but it employs a novel combination of techniques that enable quick and accurate measurements of the transmitted ...

This SBIR Phase 1 project proposes the feasibility study of secure trusted computing System-on-Chip. To prevent or delay the compromise of Critical Program Information, DoD is seeking operational embedded technology to provide the real-time encryption and authentication and "other" capabilities for protecting and processing information in tactical systems. Also, technology shall detect tampering ...
