A low-cost fiber-based octave-spanning frequency comb system operating in the mid-IR region is proposed, which is based on femtosecond-Tm-fiber-laser-pumped supercontinuum generation in a mid-IR-transmitting dispersion-engineered fiber. An all-fiber femtosecond mode-locked Tm-doped fiber laser at 2 micron will be used as a seed source for mid-IR supercontinuum generation. A femtosecond soliton fib ...

An approach to make a long endurance UAV with an 18 hour endurance and large payload will be developed based on an existing, fielded capability present operationally deployed.  The system will be built from COTS equipment minimizing cost and allowing for rapid maintenance and upgrading of the system as technology develops.  The system will be fully autonomous through launch, mission flight and r ...

This proposal will provide immediate decision support data, enabling appropriate and cost effective responses (shut down vs. continue) for training exercises/facilities. Specifically, the DoD requires the ability to “train as we fight and fight as we train”, however training is severely limited by visible emissions compliance in the current regulatory environment. Regulated facilities will hav ...

The proposed effort will demonstrate the suitability of a mature commercial production technology in meeting the requirements for a cost effective, high capacity non-volatile memory solution for space systems.  The feasibility of mitigating radiation sensitivities in, and improving the reliability of, devices built upon the selected technology will be demonstrated during Phase 1.  We will develo ...

Functional taggants are paints or inks that change their optical properties in response to specified environmental conditions, such as the presence of a chemical related to illicit weapon activities. In this project, we will develop taggant systems for two non-conventional weapon signatures. Taggants will have high chemical selectivity (avoids false positives), high chemical affinity (avoids flase ...

An innovative data collection and analysis approach is proposed to enable body mount magnetometers for space application. In order to achieve high accurate magnetic field measurement in space, the magnetometer has to be located in a âmagnetically cleanâ place, where the magnetic field from spacecraft is negligible. Usually, the magnetometers are placed on deployable booms, so that the field sens ...

The proposed study aims at accelerated development of Mo-Si-B-X (X=Ti, Zr, Hf, Re, Mn) alloys with an optimized balance of properties, via an approach of integrating thermodynamic modeling with experimental study.   On the basis of the Mo-Si-B-X (X=Ti, Zr, Hf) database developed in Phase I, a thermodynamic database of the Mo-Si-B-O-X (X=Ti, Zr, Hf, Re, Mn) system will be developed using the Calp ...

CompuTherm, LLC proposes a pilot project to develop a modeling tool that can be used to assess the durability of environmental barrier coatings (EBCs) for ceramic matrix composites (CMCs) under combustion environment. The modeling tool includes a thermodynamic database for the gas phase, a thermodynamic database for the silicate system (EBCs), and a computer software package that deals with thermo ...

ABSTRACT: We propose to employ a novel Boundary Element Method (BEM) numerical technique, demonstrated during Phase I, to develop a parallel computer code that will allow simultaneous solution, in three dimensions (3-D), of the vacuum magnetic vector potential and magnetic field structure for complex geometries. The primary advantages of the chosen approach are the reduction of the dimensionality ...

The objective of the proposed research is the demonstration of an optimized, planar-constrained Ionic Polymer-Metal Composite (IPMC) under the influence of a low, O(10V), voltage signal as a conformal surface capable of actuation of a laminar/transitional boundary layer for the goals of transition and/or separation control. The material will be modeled using standard techniques for analyzing a st ...
