The Ablation process is a liquid to solid phase conversion process that has cooling rates exceeding 400F per second coupled with steep thermal gradients approaching 900F over a .500" span. Preliminary work casting Aluminum Metal Matrix Composites (359, 30% SiCp) using this technology demonstrated better SiC particle distribution than shown in other casting processes. Preliminary data suggest high ...

The proposed project will rectify the current bottleneck in the simulation of 3D magnetic fields around high-current pulsed power devices. In the existing software, fields in the air are approximated by an artificial magnetic diffusion equation, which is both computationally expensive and nonphysical. The proposed solution avoids any nonphysical quantities and relies on exact conditions for the qu ...

In this SBIR project, a preliminary design of a highly accurate, highly repeatable impulse thruster will be completed. ASI, together with ATK, proposes to complete the preliminary design in parallel with the development of a comprehensive thruster model in a Monte Carlo environment that will account for every contributor to repeatability in the final product. Using modern uncertainty analysis te ...

Understanding the response of solid rocket motors under cook-off conditions is important to the safety of the military’s weapon arsenal. In this SBIR, CFDRC, teamed with Merrill Beckstead of Brigham Young University (BYU) and ATK Launch Systems, proposes to develop a software toolkit for simulating the response of solid rocket motors (SRM) to fast cook-off events. The complete software package w ...

To better quantify the benefits from the advanced microlens technology developed in the Phase I we plan to have microlenses installed in three astronomical telescopes. In Phase II we are planning to complete the fabrication of the remaining 4 microlenses needed for Gemini telescope and ,also fabricate microlenses for SOR telescopes in New Mexico (NGAS)and Hawaii. This will provide a direct evalua ...

Polarized-Cast Saturated Polymer (PCSP) FEG working bodies will use state-of-art ferroelectric materials such as PZT 95/5 to demonstrate their first order device characteristics. During this effort, a demonstration of this new ferroelectric material’s performance will be quantified using explosive testing. The goal is to develop a highly producible ferroelectric material with high surface char ...

Friction Stir Processing (FSP) has been demonstrated to generate refined microstructures, resulting in improved material properties. This has several areas of application. First, FSP can enhance the formability of the particular alloy of interest. This is especially important for the superplastic forming process, where the use of FSP can be used to create superplastic behavior at high strain r ...

High Energy Lasers offer defense against a variety of threats, delivering significant amounts of laser energy to a specific location on a target at the speed of light. The effectiveness of the HEL system is directly related to the ability to transfer heat into the target material. The laser must dwell on the target for a period of time sufficient to deliver enough thermal energy to render it inope ...

The additional weight of add-on armor systems and extra equipment required by the fighting force, coupled with IED tactical warfare has negatively impacted the performance of tactical wheeled vehicles. This is demonstrated by overstressed suspension systems, higher vehicle center of gravity, increased rollovers, and reduced performance on all tactical vehicles. It has been especially prevalent in ...
