ABSTRACT: We will develop a multiscale molecular dynamics/material point method (MD/MPM) methodology for determining the response of PBXs to a wide range of loading conditions as a function of mesoscale structure with emphasis on accurate representation of interfacial physics. The initial material of choice will be HMX + DOA plasticized HTPB binder. Velocity-dependent grain-grain and viscoelastic ...

ABSTRACT: Elimination of the cold chain is of vital importance for the ability to treat injured warfighters in the field and behind enemy lines. The application of an already FDA approved reagent for the stabilization of labile reagents will allow for minimal development time delaying the fielding of a new technology to fill this role. Collagen has been used extensively since the 1980s as an appro ...

ABSTRACT:Additive Manufacturing (AM) technologies are bringing significant new capabilities to manufacturing. However, a number of technical challenges remain before these capabilities can be fully exploited. The design, modeling and data management tools developed for subtractive, formative and mold-based manufacturing are not well suited for additive processes that allow pointwise and layerwise ...

ABSTRACT: The research team will specify a data model, database, and preliminary architecture for the Prognostic Scheduling system. A proof-of-concept software demonstration will be developed, including support for database, data mining, data fusion, and prognostic scheduling software capabilities. The data mining capabilities will be deployed to a "Big Data" environment to improve its computation ...

Compositex, Inc. proposes to continue the development of a promising new material and fabrication technology for high performance motor cases and propellant tanks. This process using readily-available, low-cost, domestically-produced, environmentally-friendly thermoplastic raw materials. High-cost capital equipment is not required. This technology can potentially result in revolutionary near-ter ...

Analytic Design Laboratories proposes a Next Generation FPGA that is deterministically place and routable.  Conventional FPGAs rely on synthetic annealing to optimize function placement and connection routing.  Synthetic annealing randomly moves functions and connecting paths to improve circuit performance to an acceptable level.  The side effect of random improvement is jumbled signal flow and ...

The objective of this proposal is to develop a feasible design for intermittent electrical fault detection and location for a weapons system using analog S/SSTDR for continual monitoring. We have already demonstrated the feasibility of the basic S/SSTDR technology for live aircraft in flight where analog real-time, randomly occurring, anomalous or intermittent age-related failure events are common ...

Temperature sensors that can monitor temperature directly on various locations in gas turbine engines are necessary for prognosis and diagnosis of engine conditions during operation.  However, reliable temperature sensors working under the harsh conditions of jet propulsion are not currently available.  We propose to develop thin film thermocouples using materials which are stable at high temper ...

ddddThe objective of this project is to develop a strategy to recover micro air vehicles into a flying aircraft. Our solution combines three key technologies that have received significant research attention in recent years, namely towed cable systems, cooperative control, and vision-based terminal guidance. We propose to demonstrate the feasibility of using a flying-aircraft mothership pulling ...

A need exists for a reliable, non-destructive, in-situ method to monitor the chemistry of solid rocket motor propellant to determine its health and stability during the service life of the motor.  Ideally, the sensor would be able to monitor the chemical components of the motor and not affect the propellant, the liner, or the rocket motor composite casing.  The proposed program will develop an o ...
