The European Union''s RoHS and WEE Directives mandated the elimination of the carcinogenic, hexavalent chromium coatings for metals, including magnesium and zinc-nickel plated substrates.  The purpose of this project is to find chemistry that will meet requirements of industry performance specifications and of the mandate.  METALAST intends to explore trivalent chromium in conjunction with two o ...

The major requirements for this program include the modeling of optical switching fabric technologies appropriate to space-borne systems at very high speed. Specifically, this program will evaluate two OptiComp candidate optical transceiver technologies against a Serial Rapid IO switching fabric. A down-selection to one optical transceiver technology will be made. Then, a simulation of that Serial ...

The major requirements for this program include the modeling of optical routing technologies appropriate to space-borne systems at very high speed. This program will investigate optical routing at speeds to from 3.125 ro 10 Gbps per channel, with a wavelength/channel density from 4 to 16 wavelengths. Models will be constructed for these regimes, and an experimental demonstration of an 8-wavelength ...

The proposed program will develop OptiComp''s coarse WDM transceiver manufacturing technology.  This WDM optical transceiver technology is highly novel, emphasizing manufacturability, ruggedization, modularity, ease of upgrade and qualification, extensive built-in diagnostic monitoring and test capabilities, as well as superior performance with reduced manfacturing complexity.  The modular desig ...

The goal of this SBIR is the enhancement of the current state-of-the-art combustion instability analysis tools.  The planned enhancement is focused on capturing the effects of injection element distribution and the inclusion of substantial film cooling and diluent injection.  These characteristics are extremely important in the design of high-pressure oxygen rich staged combustion (ORSC) engines ...

The goal of achieving efficient flow control becomes even more challenging for MAVs as a result of the significant weight and size limitations. These preclude the use of complex hardware and control schemes which may be usable in conventional aircraft. In this research program, we propose an ambitious but realistic approach for developing and implementing, self-adapting, integrated sensor-actuato ...

Abstract

The objective of the proposed Phase-I research effort is to perform velocity, temperature, pressure, and H2O concentration measurements at the end of a detonation tube and the exhaust of a detonation-powered turbine at a rate of 50 kHz.  These measurements will help quantify the efficiencies of detonation-powered devices.  High-speed measurements of temperature, H2O mole fraction, pressure, and ...

We propose an innovative sensor technology that combines a high-bandwidth Time-Division Multiplexing laser system along with a 3D tomographic reconstruction model to provide spatially and temporally resolved 3D temperature and H2O concentration image of the flow field at data rate of 50 kHz.  The primary objective of this Phase-I research effort is to perform the feasibility study of 3D tomograph ...

Laser micromachining is being widely used in every industry, including aerospace, automobile, microelectronics and bio-technology. The recent advent of commercial turn-key, high power femtosecond lasers has prompted a great amount of interest in using femtosecond lasers for machining. It has been demonstrated that the femtosecond laser has potential for achieving high precision owing to its extrem ...
