We have in recent work developed large-area flat panel displays, for a classified military application, which allow for high dynamic range/color contrast in the Visible (70% Transmission dynamic range), mid- and far-IR (up to 90% Reflectance range). The displays are thin film (2 mm) flexible devices based on poly(diphenyl amine) and structurally related Conducting Polymers (CPs . A uniqe design an ...

RESEARCHERS ARE DEVELOPING A HIGH PERFORMANCE COMPUTING ENVIRONMENT FOR LARGE-SCALE ENGINEERING PROBLEMS, MAKING ACCESSIBLE THE MOST RECENT ADVANCES OF PARALLEL COMPUTING AS A CRITICAL COMPONENT IN EVERYDAY ENGINEERING DESIGN. THE SUCCESS OF THIS WORK, BOTH COMMERCIALLY AND TECHNICALLY, WILL BE BASED ON THREE ELEMENTS. FIRST, FLUENT WILL SERVE AS THE FOUNDATION FOR THE NEW PARALLEL CODE. FLUENT ...

As a leading company in computer aided design of microwave and high-speed electronics, Compact Software in collaboration with the Naval Research Laboratory's InP device development team, is interested in developing a much needed Physics-based simulation tool for Inp-based HEMTs and HBTS. We will develop and validate state-of-the-art HEMTs and HBTs models and combine them into our commercially avai ...

Control of trailing vortex wakes is an important challenge for both military and civilian applications. Ingestion of concentrated vortices in propellers can lead to undesirable noise in submarines, while the encounter of aircraft wakes with following aircraft presents a significant safety hazard that limits capacity at all major U.S. airports. This proposal involves an assessment of the feasibilit ...

Helicopter vibration due to nonidentical inertial and aerodynamic properties of rotor blades continues to plague Army aviation maintenance personnel. This vibration manifests itself at the rotor rotational frequency, and is currently controlled through the addition of blade root and tip weights and the bending of trim tabs. Application of Individual Blade Control (IBC) offers the promise of automa ...

To fully exploit the adverse weather potential of tilt-rotor aircraft, an ice detection system is required both for caution and warning and for management of ice protection systems. Appropriate ice detection capability will offer improved power consumption along with improved performance (e.g., effective ice shedding) and increased safety by alerting the crew to an unexpected icing encounter. A sy ...

Tilt rotor aircraft are required to operate in flight conditions ranging from hover and low speed edgewise flight to high speed cruise. It is not possible to achieve optimal performance in all flight conditions with rotor blades with a fixed twist distribution. The goal of this project is to conduct a design assessment of variable twist rotor systems that will allow in-flight adjustment of blade t ...

The objective of the proposed effort is to design an all solid-state, eye-safe (1.5 um) laser that will abe superior to existing eye-safe lasers in terms of power, efficiency, cost, and beam quality. The proposed laser system is based on solid-state Raman shifting of Nd:YAG laser radiation using barium nitrate. Several designs will be presented and performance characteristics (based on properties ...
