ABSTRACT:Noise levels of military jet aircraft have significantly increased as the power of the engines has increased creating a community noise issue around military airfields. Current noise monitoring requirements only measure sound pressure levels which do not correlate to human annoyance / disturbance. Sound Answers plans to apply their extensive Sound Quality background to establish new acous ...

ABSTRACT:The feasibility of developing a photonics-based real-time high-power-microwave (HPM) near-field mapping system is to be investigated. The system is intended to contain multiple non-intrusive near-field sensors so that it can simultaneously detect undistorted versions of broadband HPM electric- and magnetic-field transients over a desired field-mapping area. The system will be able to take ...

ABSTRACT:Cognitive skills/capabilities are important for the military personnel to fulfill tasks and to ensure mission efficiency and success. In the past decade, there are abundant researches suggesting that non-invasive brain stimulation via transcranial direct current stimulation (tDCS) holds great promise to enhance a soldier's cognitive performances. Although models to predict the tDCS curren ...

ABSTRACT:Innovative Technology Applications Company, LLC proposes the development of an analytical tool that predicts jet noise and engine performance for current and future generations of supersonic two- and three-stream engines. The goal is to provide robust and reliable noise predictions in minutes that can be used for design optimization. The physics-based approach will be capable of addressin ...

ABSTRACT:The goal of this proposed R & D project is to develop safe, low cost, robust lightweight electrochemical power sources for space launch vehicle upper stages, and flight termination batteries for space launch vehicle first stages. The project specifically addresses a Flight Termination Battery (FTS) that weighs less than 7.0 lbs., another Flight Termination System Battery that weighs less ...

ABSTRACT:IR Telemetrics will leverage its existing data acquisition technology to design, build, and demonstrate a Compact, High Channel Count, High Frequency, Rotating Data Acquisition and Transmission System. The modular, scale-able system will digitize with over 18-bit resolution and a minimum 300 kSPS sample rate and be able to spin at over 25,000 rpm. Data transmission will be accomplished wi ...

ABSTRACT:The proposed research effort will develop passive Oscillating Heat Pipe (OHP) structural heat spreaders to attach to small, ultra-high heat flux devices (e.g., GaN power amplifiers) and dissipate their heat loads uniformly across the spreaders' relatively large heat sinking surfaces - and do so with minimal thermal resistance. The research team will design, model, fabricate, test, and ana ...

ABSTRACT:Modulator linearity and efficiency, in addition to bandwidth, are important parameters in characterizing a modulator. In general, improving modulation efficiency is highly desirable since higher modulation efficiency allows lower RF signal to impose equivalent change in the optical beam whereas improved linearity increases the dynamic range available to analog signals conveyed and process ...

ABSTRACT:Hyperspectral imaging is a technique used to simultaneously capture spatial and spectral information of an object scene, making it a valuable technique for applications in remote sensing and military battlefield environments. In the case of long wave infrared (LWIR) imaging, a hyperspectral approach offers an opportunity to improve upon the detection capabilities of standard broadband sen ...

ABSTRACT:In response to Air Force SBIR topic # AF151-178, Signature Research, Inc. proposes to develop a highly innovative solution that provides a leap forward in the collection of calibrated infrared (IR) ground mobile target signature data. The specific goals of our Phase I proposal are to conduct a trade study to evaluate multiple alternatives, and produce a preliminary design of the most desi ...
