Fastening and joining technology has lagged behind the progress that has been made in other areas of composites for advanced air vehicles. Aerotech proposes the development of reversible polymeric adhesive bonding of composites using variable frequency microwave energy. With this method, composites are bonded using Poly Ether Ether Ketone (a high temperature thermoplastic) which is cured using v ...

This proposal will address the development of a digital receiver and exciter (DREX) technology for next-generation scalable missile-defense radar. A DREX is currently being specified at the sub-array level to feed an analog tile or panel subarray. This al

Missile threats faced by our country are constantly increasing in lethality. The weapon used to counter such missiles is the kinetic interceptor. To work effectively, the reentry vehicle (RV) location must be precisely known. Confusing objects within the reentry complex make the key discrimination process very difficult. Coherent distributed aperture (CDA) radar represents an important advance in ...

The design and development of scalable panel-based phased-array radars requires the high density integration of solid-state components and adequate thermal mitigation within the array lattice constraints. The current integration technologies such as system-on-a-chip (SOC), multi-chip-module-deposition (MCM-D), and system-on-package (SOP), will help miniaturizing sub-modules for various functional ...

Current monostatic radar systems suffer fine tracking and discrimination performance degradation when encountering mainlobe jammers deployed within a reentry complex. As a result our forces may be vulnerable to attack. During Phase I, we have developed di

BTech Acoustics proposes the development of a detailed Cylindrical Transducers User Toolkit for the design of underwater acoustic transducers and sonar systems employing cylindrical transducers and relaxor piezoelectric single crystals. The Cylindrical Transducer User Toolkit (CT-Toolkit) will allow a detailed, accurate and user-friendly method to provide the acoustic performance for cylindrical t ...

Superior high-temperature performance requirements for highly stressed rotating components of the compressor section in advanced Army turboshaft engines cannot be met by the existing materials and require sophisticated materials solution concepts. The objective of this SBIR program is to develop a reinforced high temperature titanium material system for impeller applications in advanced Army turbo ...

Gnosys, the University of Alabama in Huntsville, and SAIC propose that entity level performance data be “rolled-up” into aggregate performance data and used to resolve unit level combat at the unit level. Such an approach for conducting aggregate simulation would realize the advantage of employing validated entity level data but also keep the advantages inherent in aggregate simulation of com ...

A yb laser at 976 nm is a three level system. By placing Sm in the core (to reduce stimulated emission above 1,000 nm) and Yb in a surrounding ring, a more efficient laser at 976 nm can be obtained. This will be Q-switched to serve as the first stage of a pulse source in a MOPA configuration. The second stage will be a HOM fiber designed to amplify the pulses from the first stage. With a HOM fiber ...
