The Phase I deliverable will be a physic-based model which represents a CMC gas turbine component concomitantly at the material level and the structural level. This model will be probabilistically analyzed to account for the uncertainties in material properties and the uncertainties in the size and impact velocities of possible foreign objects (FOD). A ceramic material must display sufficient capa ...

A unique type of air lubricated thrust bearing called a Wave Bearing is proposed to assist a rolling element bearing to carry the thrust load and to improve the bearing’s life when used in a micro gas turbine engine. The Wave Bearing technology will provide improved reliability, safety and life compared to rolling element bearings used alone, as well as to allow simplification of engine design a ...

Modern warfare is becoming increasingly dependent on high technology and the means to power it. Lithium-ion batteries are a popular power choice due to high energy density and long charge hold. Unfortunately Lithium-ion batteries also have some distinct disadvantages including the possibility of catastrophic failure. This is of significant importance when the battery failure may take place in clos ...

The goal of this Phase I proposal is to develop a synthetic, low cost, and benign simulant for biowarfare agents (BWA) to be used in the testing of standoff sensors. Orono Spectral Solutions Inc. (OSS) has performed preliminary work leading to the identification of benign ingredients that, when combined in a predefined mass ratio, mimic UV-Vis and infrared signatures of BG spores. This work was pe ...

The overall goal of this Phase I project is to demonstrate the feasibility of an infrared transparent, micro-fluidic sampling system that will lead to a field-deployable detection system capable of detecting low ppb levels of chemical warfare (CW) agents in water. To accomplish this goal, the proposed detection system will combine high surface area, organically modified mesoporous oxide absorptiv ...

The Missile Defense Agency (MDA) seeks technical investigations related to the development and application of advanced electronic materials, processes, and devices to meet its need for radiation hardened, high performance electronics for critical space and missile applications. With the advent of smaller transistor dimensions and reductions in price per bit, significant changes in materials and pr ...

While there are established methods available in determining the fatigue life of critical rotating components, there is still room for improvement for better understanding and prediction of life limiting factors. Improved risk assessment of jet engine disk components would require probabilistic modeling capability of the evolution of microstructural features, residual stresses and material anomali ...

SET, Inc. proposes to develop lattice-matched AlInN/GaN HFET structure on free-standing GaN substrate. By employing native low-defect GaN substrates and by using lattice-matched heterostructures with the incorporation of indium, we expect dramatic enhancement of these HFET in power density, reliability and high frequency operation. Homoepitaxial growth on native substrate and the use of AlInN/GaN ...

Thermo-mechanical processes of turbine disks have been progressively improved to meet microstructural requirements tailored for advanced, sustainable high temperature performances. However, the chemistry of typical Ni-base turbine disk alloys is very complex, and yields a variety of phases and microstructural anomalies under different thermo-mechanical heat treatments. These microstructural hetero ...

This Phase I STTR program seeks a new fabrication method to produce stronger (>100 kpsi) and tougher (>10 MPa m1/2) ultra high temperature Ta-Hf-C-based composites (UHTC) with an outstanding oxidation resistance for use as thermal protection systems for hypersonic applications, as well as for advanced rocket nozzle throat components. UES will apply a novel "Top Down" approach to control the micro ...
