In phase I, we have proven the feasibility of using the microwave cavity perturbation technique to detect and quantify DoS in marine aluminum alloys. We implemented an alpha version sensor prototype, characterized and validated its performance using ASTM G67 method. We also identified methods to further enhance the sensor sensitivity, so that DoS in the low (a few mg/cm2) to moderate range can be ...

In Phase I, NP Photonics has successfully demonstrated the feasibility of a fiber-based THz source that can generate high power, narrow linewidth, and tunable THz radiation by leveraging NP’s proprietary unique fibers, fiber lasers/amplifiers, and THz techniques. In Phase II, we will develop the monolithic high power ~ 2 micron pulsed fiber laser system for the proposed fiber-based THz source un ...

Voltage compliant metal-semiconductor field-effect-transistors (MESFETs) provide solutions to critical problems arising from the reduced operating voltage of highly scaled CMOS. This Phase 2 activity will develop MESFET based circuitries that allow high voltage applications to coexist on future, highly scaled low voltage CMOS applications. Our patented MESFET technology will be used to develop bo ...

A method of inducing non-contact creep deformation was demonstrated in ultra high temperature diborides via electro-magnetic forces. The Phase II effort will focus on refining the Electro-Magnetic Mechanical Apparatus to exhibit better control of test variables and have a higher degree of automation. This novel approach to characterizing Ultra High Temperature Materials will require a standard m ...

Scientific Monitoring, Inc. (SMI), Stanford University (SU) and Pratt and Whitney (PW) propose to conduct research to develop, implement, apply and realistically demonstrate new methods to analyze and predict the stability and performance of a distributed gas turbine engine control (DEC). The approach will be to develop the requirements for a DEC network. Then these requirements will be used to ...

Command and control battle maps and mission planning can be greatly enhanced by the representation of the battlefield in 3 dimensions. Showing perspective views, depth and occlusions allows for a better understanding of the situation, and assists in avoiding error when interpreting the terrain. Such maps already exist and are in use, but are based on permanent holographic media that cannot be refr ...

Modeling of multi-flight-mode rotors that provide lift in hover and lift is proposed. Work leverages on company sponsored development efforts that have followed an innovative risk reduction spiral technology development approach. The proposed effort features a wind tunnel test in Phase I to demonstrate modeling fidelity.

We propose an all-fiber approach to heat removal from devices such as high-power RF amplifiers. In our approach, the cooling fiber segment, the pump fiber laser, and the optical fiber used for photon waste removal are all integrated into a single fiber configuration. NP Photonics' high efficiency thulium-doped fiber lasers are used to pump high purity thulium-doped glass fibers, which provide the ...

High strength copper alloys are preferred as the base rails for railguns due to their combination of strength and electrical and thermal conductivity, but suffer damage due to high current densities, arcing, gouging, and exposure to molten aluminum armatures. A refractory metal/alloy coating on the copper base alloy is an attractive approach for increasing rail life if the refractory metal coating ...

The Team of M-DOT Aerospace and University of Texas, Arlington propose to analyze, construct and test a 40 mm foil thrust bearing featuring a unique bump foil concept and top-foil profile designed by Dr. Daejong Kim. The design is simple, affording low production cost in high quantity. The design can be adapted for use on small gas turbines, small turbochargers and any small rotating machine that ...
