There is a need for a lightweight, high-performance, insulation to protect the internal systems in hypersonic vehicles. A passive thermal protection system (TPS) design would be simple and reliable. As designs evolve, there is a need for TPS insulation materials that can be additively manufactured. Our Phase I approach will additively manufacture pre-ceramic scaffolds that are used to create low d ...

The innovation proposed here is a novel carbon-carbon composite (CCC) manufacturing method based on polymer infusion and polymerization (PIP) using a novel precursor polymer with exceptionally high char yields. This results in a material that has the promise of excellent quality and mechanical properties, while offering the breakthrough advantages of (1) greatly reduced or eliminated need for back ...

This topic identifies the need creating a Modeling and Simulation (M&S) development and execution environment that significantly decreases the time to execute statistically significant batches of stochastic simulation runs for the purpose of estimating scenario output and outcome distributions while improving statistical knowledge of the outcome distributions. The strategy sought by this topic is ...

To advance simulation techniques, such as high-fidelity computational fluid dynamics (CFD), to accelerate maturation of DACS design through design-time trade studies, there is a need for new, test-validated models that improve both computational performance and the accuracy of the reacting jet in hypersonic crossflow simulations. ATA and CUBRC (a research institution with leading expertise in aero ...

We propose to develop Para-DEVS, an extension of the existing modeling and simulation (M&S) environment overcome two major hurdles that must be overcome to implement paratemporal simulation techniques for application to execution of large stochastic models. We propose to develop techniques to achieve scalability, the ability to overcome the combinatorial explosion of branching arising from multipl ...

In the proposed effort, we will develop the fundamental building blocks to develop a high performance, low Size, Weight, and Power (SWaP) ultrashort pulse Femtosecond Direct Diode Laser System (fsDDLS) capable of generating and sustaining filaments/plasma channels in the atmosphere ahead of a vehicle in hypersonic flight to reduce drag, heating, and displace shock.

The U.S. missile defense system (MDS) includes various assets located at sea, on land, and in space that provide global coverage against missile threats to the U.S. and its allies. Elements of the MDS create a layered defense capability providing detection, tracking, discrimination, and intercept capabilities against missile threats. As the MDS and its elements continue to grow and evolve to keep ...

Alphacore and Vanderbilt University will develop innovative, cost effective methodology and solutions for radiation testing of microelectronics, to evaluate and distinguish between radiation effects from a persistent beta environment and a persistent gamma environment, and determine the circumstances where testing for one environment is sufficient to show survivability in the other, or in a combin ...

We will investigate the radiation effects on microelectronics due to gamma-rays and beta-rays and compare the effects on electrical and material properties between the two radiation types to formulate a quantitative mapping of radiation types (gamma and beta) and effects. The purpose is to: 1) Develop an overall physics-based strategy; 2) Define the experimental design, guided by analytical calcul ...

The Attollo team proposes a multi-pronged approach where we will investigate both Gallium-free and Gallium-containing superlattices through band-structure modeling, device design, and fabrication experiments to reduce leakage currents to a minimum in order to approach theoretical performance.
