There is a great need and opportunity to develop lower cost manufacturing process for ceramic tile-based composite armor system for military tactical vehicles. The threat levels encountered by the military tactical vehicles, particularly due to the Improvised Explosive Devices (IED) pose an ever-increasing need for more lightweight and effective vehicle armor system at an affordable cost. A low-co ...

Genome-scale predictable cellular design and engineering of biomanufacturing systems is the overarching a goal of DARPA's Living Foundry thrust and, if realized, will enable rapid engineering of living biosystems for a broad range of applications in biotechnology and pharmacology. However, constructing living cells with designed genome is not fully automated and is severely limited by inhere ...

Clear Science Corp. and the University of Texas at Austin will develop and demonstrate technology that accurately quantifies aero-optical distortion associated with high-energy laser (HEL) weapons on rotorcraft and will utilize the information in designing adaptive optics (AO) systems to maximize HEL system performance over the full range of flight conditions. Aero-optical distortion arises from v ...

Integrally bladed rotors (IBR), also called blisks, are becoming increasingly common in the compressor and fan sections of modern turbine engines. The integration of the blades and disks into a single part has the advantages of reduced part count, reduced weight, increased reliability, and increased performance. However, a drawback of this technology is that individual blades cannot be easily repl ...

The technical objectives of this proposal are: (1) design a grating-coupled surface-emitting (GCSE) active-photonic-crystal (APC) 4.6 micron-emitting quantum-cascade laser (QCL) to deliver 15 W diffraction-limited CW power in the main lobe of the far-field beam pattern; (2) design a GCSE-APC QCL structure with monolithic aperture-filling optical elements for obtaining close to 90 % of the surface- ...

Susceptibility to delamination is one of the major weaknesses of ceramic matrix composites (CMCs). Knowledge of the resistance of composite to interlaminar fracture is essential for life cycle prediction analyses of structural components. The current test method for Mode I-interlaminar fracture toughness, the double cantilevered beam (DCB), is not satisfactory for thin CMC specimens because the co ...

ABSTRACT: Clear Science Corp. and Princeton University propose to develop and demonstrate software that accurately and efficiently simulates the full set of physics associated with aircraft flight operations. The critical attributes of the proposed framework are accuracy, computational efficiency, and inclusiveness. More accurate computational models will support higher fidelity analysis during ...

ABSTRACT: In this STTR phase II, HYPRES and University of California San Diego team will demonstrate a small size, weight and power Direction Finding (DF) system prototype based on SQUID array technology. High sensitivity, linearity, and wide bandwidth of SQUID arrays antenna sensors will be enable close spacing of smaller antennas even for high frequency (HF) range. Our SQUID array designs are ...

ABSTRACT: We propose to develop an assured information sharing framework for cloud-based systems that leverages our ongoing work in the areas of policy-based usage management and semantic interoperability. The development of this framework will involve the creation of a novel approach to information sharing that treats security as a commodity that can be dynamically provisioned within the cloud, ...

Flexible electronic and optical devices, including sensors/detectors, waveguides, and photonic crystal structures, have significant promise for improving communication and information processing capabilities in a number of military and commercial applications. However, the development of such flexible devices has been hindered by the lack of effective manufacturing processes for producing these de ...
