Based on the foregoing, the goal of this proposed project is to develop a novel methodology based on the peridynamic (PD) theory to predict fatigue life of aerospace structures with high fidelity. A new fatigue model will be implemented in PD framework. The model and its implementation in PD will be validated against experimental measurements. A pre- and post- processor with a graphical user inter ...

PM & AM Research and Texas A & M University will develop an innovative non-invasive technique to meet the current DoD need for simultaneous acquisition of the velocity and acceleration fields of both a fluid and solid undergoing a fully-coupled fluid-structure interaction. Modern composite structures are being designed to flex or deform under fluid loading to attain desired performance gains. The ...

US Navy submarine forces currently employ an independent team to test, measure, calibrate and certify radio frequency (RF) signal paths through sail mounted antennae to the inboard radio rooms in a process that can take in excess of 60 man-days to complete. Ships personnel have no means of calibrating or performing an operational verification of the ES suite once underway. Ships have no means of p ...

An electromagnetic launcher also known as a rail gun is a major gun system the Navy is developing for long range fire support. A refractory metal cladding on a copper rail is enabling for the successful high fire rate and long life of the electromagnetic launcher. Heretofore, a successful process for adherently cladding/coating a refractory metal onto a copper rail that withstands the rigors of an ...

Safe, Inc. proposes to develop an occupant surrogate with functions and performance tailored to the needs of the vehicle blast test community. The new ATD will use a suite of technologies already developed and the result will be far more biofidelic than the Hybrid III. The new ATD will exhibit realistic injuries such as bone fractures at the appropriate loadings. Yet this new ATD can be instrument ...

Currently, no appropriate anthropomorphic test device (ATD) for ballistic testing is available. The most commonly used ATD for research purposes is the Hybrid III, which was designed to examine human body dynamics in vehicular accidents. Although these devices are well instrumented, they are limited in the information they can provide in evaluating injuries from a ballistic incident. The cast alum ...

NP Photonics proposes to develop a tellurite fiber coupler system capable of combining multiple mid-infrared laser sources at different wavelengths for infrared countermeasure applications. Low loss mid-infrared fiber couplers with the desired wavelength dependence will be fabricated with NP Photonics"proprietary tellurite fibers by tailoring the geometry of the coupling zone. Wavelength combining ...

Corvid Technologies is excited to offer a unique solution for protecting tactical vehicles during high-speed external transport. The innovative design employs a fabric net structure rigged to the vehicle which significantly reduces the impeding air velocity on critical components. This approach provides the necessary protection with minimal impact to installation time, complexity, portability, and ...

Pitting corrosion limits the lifetime and performance of turbine engine bearings and gears operated in marine environments. A number of alloys and improved treatments have been attempted to increase corrosion resistance while maintaining mechanical performance of the bearings, but few meet the expectations. Some more corrosion resistant treatments such as the low temperature expanded austenite (S- ...

This Phase I SBIR program proposes the development of infrared transparent, p-type conducting Mg doped CuCrO2 films (CuCr1-xMgxO2, CCMO), which has sheet resistance less than 10 ohms squared, as the replacement of the electrical conductive metal grids for Magnesium Aluminate Spinel (MgAl2O4) windows. The CCMO films deposited on spinel windows by RF Magnetron Sputtering System (RFMSS) will serve as ...
