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 ...

Research is proposed for the development and implementation of state of the art, reduced order nonlinear aeroelastic models for multidisciplinary/multi-fidelity optimization problems. Highly efficient and accurate aeroelastic simulation tools will be constructed based upon the mathematical formalism of optimal prediction theory and a novel implementation of a filtered harmonic balance solution met ...

In this Phase I STTR program teaming with magnetic and materials experts Advanced Powder Solutions will develop a low cost high strength, high tensile, nano-structured soft magnetic alloy and rapid fabrication of magnetic component for actuators using innovative consolidation process. Teaming with system integrators and university experts Phase II will continue the characterization of these high t ...

This Phase-II proposal addresses Air Force STTR Topic AF07-T031 (Robust, Autonomous, Inexpensive Space Weather Sensors), which was released with the objective to develop robust, autonomous, low-cost sensors to deliver near real-time, three-dimensional space environmental data.  The Air Force requires accurate knowledge of the ionospheric environment in order to understand and predict the ionosphe ...

The proposed barium strontium titanate (BST) nanodielectric devices will combine some of the best features of bulk and thin-film based tunable dielectrics: low microwave losses, high tunability at high fields, the potential for low operating voltages, and less temperature dependent dielectric response. The miniaturization of devices and reduction of insertion losses requires developments of mater ...

CMU and Magnetics, A Division of Spang and Co. have developed a new high-saturation induction, high-temperature nanocomposite alloy for high-power inductors. This material has FeCo nanocrystals with an A2 or B2 structure embedded in an amorphous matrix. Field annealing resulted in a linear B-H response with a relative permeability of 1400, constant up to fields of 1.2 T. The material was used in ...

Our Phase I program will extend and validate a high-speed engineering transitional model (ETM) using new CUBRC data sets (such as HIFIRE-1) of interest to the Air Force. The ETM is responsive to tunnel noise and wall heating, and predicts the overshoot in heat transfer observed in transitional data. The model solves PDEs for transition onset as well as for an intermittency parameter that blends th ...

Discovery Machine, Inc. is partnered with Pennsylvania State University to produce a best practices capture system that goes beyond the storage and dissemination of lessons learned. The proposed system will leverage warfighters’ specific knowledge as deployable knowledge assets. These knowledge assets will be executable best practices that can be embedded in job aids and training systems. Th ...

The need for improved tools for developing, tasking and operating Moving Target Indication Radar sensor systems is becoming more critical as MTI is finding uses in counter-insurgency, counter-terrorism and asymmetric warfare. The Moving Target Indication Interpretability Rating Scale Toolkit (MTIIRS Toolkit) will provide the needed tools to support USAF and other MTI sensor development, warfighter ...

FBS, Inc. and The Pennsylvania State University propose the development of a novel ultrasonic structural health monitoring (SHM)/nondestructive testing (NDT) technology. The goal of our work is to bridge the gap from the short time transient ultrasonic guided wave analysis to the long time modal vibration analysis. This new technique will be sensitive to material properties, defect presence, and ...
