The proposed work will result in a method for production of dense, hard, tough, strong tungten carbide (WC) ceramic material for ultimate use as the penetrating core in armor piercing projectiles. Focus is on the development and feasibility of a titanium silicon carbide (Ti3SiC2) based matrix as a replacement for cobalt based materials currently used. Ti3SiC2 is a so called ductile ceramic which ...

Mathematical models of physical and biological systems contain parameters that need to be estimated from measured data. Models with parameters distributed probabilistically require the estimates of a probability measure over the set of admissible parameters. We propose to use frequentist-based approaches for non-parametrically estimating probability measures that describe the distribution of par ...

A technique that enables new methods of obscurant modeling with faster rendering while maintaining or improving physical fidelity is proposed. The proposed technique not only exhibits the statistics of voxel based obscurants, but matches real-world data as well. The main objective from Phase II efforts will be a further refinement of the flow field and particle technique of generating physically c ...

ABSTRACT: NextGen Aeronautics Inc. proposes use of rapid prototyping (RP) technologies, design process improvements, and novel sensing technologies to significantly reduce time and cost of transonic aeroelastic wind tunnel model development and improve their direct correlation to CFD data. The use of modern RP technologies will allow for model design variations such as variable modulus (stiffness ...

In this STTR program, Structured Materials Industries, Inc. (SMI) and partners are developing high efficiency, switchable RF filters. The technical approach is based on thin films of paraelectric BaxSr1-xTiO3 and SrTiO3, which can show piezoelectric behavior under an applied DC bias. When integrated into resonator structures, these materials can act as both an RF filter and an RF switch. Combin ...

New Jersey Microsystems, Inc proposes to develop an economical thermopile array with sensitivity maximum in the long wave infrared region (LWIR). Current infrared detectors are too expensive to be widely deployed in large numbers. The proposed MEMS technology is simpler, more manufacturable, and therefore less expensive than existing bolometers and ferroelectric devices based on rare earth and ...

ABSTRACT: The proposed work aims to build a physics-based rapid turnaround simulation capability for resolving combustion dynamics in liquid rocket engines operating at trans-critical and supercritical flow regimes. The methodology will explore both Reduced-Order Methods and Reduced-Basis Methods as potential candidates for efficient unsteady flow simulation, data storage and retrieval, and data ...

NextGen Aeronautics (NextGen) and University of Southern California (USC, RI) team of experienced composite materials, structural design, and analyses personnel are responding to the opportunity to develop stochastically verified composite structural desi

ABSTRACT: Stability phenomena that are of vital interest in liquid rocket motor development involve a confluence of diverse physics and interactions across many system components. Any comprehensive, self-consistent numerical model is burdened by a very large computational mesh, stiff unsteady processes which limit permissible time step, and the need to perform tedious, repeated calculations for a ...

Carbon fiber reinforced polymer composite materials are light and strong, however the development of composite aerostructures has been expensive and slow. Custom tooling is required for each part produced, significant capital investment is required to win
