Radiative heat transfer is a dominant mode of heat transfer in combustion and propulsion systems as well as for hypersonic flow encountered during planetary entry. Solution of the Radiative Transfer Equation (RTE), which is an integro-differential equation, places stringent requirements on the computational resources as: (a) the radiation depends both on spatial and angular dimensions, (b) radiati ...

The United States Missile Defense Agency (MDA) is searching for a software-defined multi-channel radar receiver that would provide improved performance and added flexibility over currently deployed radar systems. In response, MaXentric is proposing a system codenamed MASR (Manycore Adaptive Software Radar). The MASR system is composed of a hierarchy of X-band front-ends, high-speed digitizers, F ...

Micro gas turbine engines with state-of-the-art ultra-compact recuperators could be a real game-changer for small unmanned air vehicles and portable power generation. A key enabling technology for these engines is a low-cost, high speed bearing system that has long life, while operating without either a separate lubrication system, or oil in the fuel. For this Phase I STTR effort, Xdot Engineerin ...

The objective of this Phase I proposal is to demonstrate, through a rigorous design and modeling, the feasibility of a single chip Transmit/Receive Integrated Circuits (TRIC) with on-chip controller and compensation networks for next generation X-band radar systems. TRIC will include RF, analog and digital circuits on a single chip. TRIC functionality would include Frequency-modulated Continuous ...

The Progeny – University of Utah team proposes a new approach for flow noise reduction to improve acoustic sensor performance. Our proposal is to investigate the ability of controlling the turbulent flow by utilizing acceleration which makes the flow locally laminar. Our proposed method of achieving acceleration is to send the flow around a concave surface, by adding a “two-dimensional bump ...

Stealth is a primary consideration in design and operation of ships and submarines in the Navy fleet. Noise in hydraulic systems and piping is one source of unwanted noise. A method to measure and monitor this noise is essential to controlling and eliminating these noise sources. With the assistance of UMASS Dartmouth we will present a method to externally measure the fluidborne sound pressure lev ...

Our objective is to develop advanced mediator architectures for efficient electron transfer in enzymatic fuel cells (EFCs) for low power systems. The proposed EFC will leverage ongoing research at both CFDRC and Michigan State University to provide a fully-integrated lightweight, low-cost, manufacturable, and renewable power supply, for various military and civilian applications. EFC systems offer ...

Accurate real-time waterborne pathogen detection is of paramount importance to security of U.S. military forces and installations. Fieldable high-throughput pathogen concentration is a critical analytical need for enhanced detection performance. Existing concentration methods are time-consuming, bulky, labor-intensive, power- and reagent-hungry, and consequently ill-suited for battlefield deployme ...

Higher efficiency solar cells are needed to reduce mass, volume, and cost of DoD space missions. However, to achieve higher efficiency and radiation hardness of the best to date multi-junction photovoltaic (PV) devices, several challenges must be addressed. This project aims to develop: 1) Quantum Well (QW)-based multi-junction cell that exhibits enhanced efficiency, and 2) Radiation-hardened PV c ...

The purpose of this STTR is to develop comprehensive detailed kinetics for oxidation of C-SiC-SiO2-rubber in extreme oxidizing environment. This material is used as a coating on the outer surface of Navy weapon systems. In order to predict the fate of this material under extreme conditions and mitigate the degradation of the coating, a comprehensive oxidation mechanism is required. In Phase I, CFD ...
