The opportunity presented under this program is to develop next-generation fuel-sealing technology that can be applied to impart self-sealing capability to the most vulnerable areas of integral aircraft fuel tanks. Targeted application of the self-sealing materials will reduce the weight and fuel volume penalty associated with conventional MIL-DTL-5578 self-sealing fuel bladder constructions. New ...

A combined discrete cohesive interface fracture and continuum damage mechanics initiation and propagation toolkit for Abaqus will be developed for the residual strength prediction of adhesively bonded composite structures subjected to multi-axial loading. This tool will allow us, for the first time, to be able to simulate concurrently both the continuum and discrete damage progression at the bonde ...

Global Engineering and Materials, Inc. (GEM) along with its team members Northwestern University, Lockheed Martin, and Boeing Company, propose to develop an automatic software tool for 2D/3D fatigue crack growth prognosis of complicated structures under multi-axial loading. The XFAT toolkit will be developed by integrating a unified crack initiation and propagation model with an enhanced mesh inde ...

An advanced optical instrument is proposed with the capabilities of distinguishing between fluid and solid components of an image and measuring the velocity field and acceleration field of each. The design is based on the well known and robustly practiced principles of particle image velocimetry, but by introducing a third light pulse it produces a fundamental innovation that both enables the meas ...

We propose a self-organized chaotic attractor based CMOS/Memristor circuit framework called Self-Evolvable-Logic-Fabric (SELF) for autonomous motor control. We propose to demonstrate SELF's ability to spontaneously evolve algorithmic pathways to control a robotic arm to catch a ball utilizing visual and proprioceptive feedback while varying parameters that increase the complexity and difficul ...

Superplastic forming process (SPF) takes advantage of unique ability of certain materials such as titanium alloys that exhibit exceptionally high tensile ductility beyond its normal limits of plastic deformation at elevated temperatures and low strain rates. Within a narrow window of a combination of elevated temperatures and low strain rates, titanium alloys can withstand elongation as high as 30 ...

General Nano's Phase II proposal is centered around low cost, high volume manufacturing of Carbon Nanotube (CNT) arrays on stainless steel sheets. The proposed technology is the basis for application development projects involving structural reinforced composites, conductive composites, EMI shielding, stray light absorption, thermal interface materials, batteries and super-capacitors. Four ...

Under this STTR, Deep Springs Technology (DST) in cooperation with Georgia Tech is testing the feasibility of producing high strength Mo-Si-B composites based on the Georgia Tech method of ultrasonic spray drying Mo, Si3N4, BN powders, reacting the granules at high temperatures to MoSiB composites, and reduction extruding the sintered granules at high temperature into dense composite rods. The GT ...

Our proposal specifically addresses the stated requirements of the solicitation; we will develop software and system protection tools for monitoring the execution of untrusted software in large complex networks. This includes attacks which may be present in software applications used within the DoD (e.g. buffer overflow, code injection, rootkit patching, etc.). The proposed EDAptive DeforcE solut ...

Military GPS receivers have to operate in electromagnetically challenged environments. CRPAs have become the antennas of choice for electronic protection to GPS receivers. For optimum performance and precision navigation, CRPA weights are adapted using beam forming/null steering approaches. Due to the limits on size, weight and power (SWAP), one may not be able to use beam forming/ null steering a ...
