In a ship's bilge, water mixes with oils, cleaners, and other liquids and dissolved solids to form a complex wastewater solution harmful to the marine environment. Naval vessels carry onboard oil/water separators (OWS) to prevent discharging oily wastesoverboard. OWS systems can remove oil from water; however, serious problems arise when other contaminants, like detergents, are present. These in ...

Oil lubricated gearboxes can be very costly with oil life and maintenance issues, complex sealing, seal shelf life issues, and oil sump requirements. Barber-Nichols Inc. will investigate alternative lubrication concepts to reduce these costs.Investigation areas will be water lubrication, dry or semi-dry lubrication, and material selection. These concepts have potential of significantly reducing ...

Pure oxygen is usually produced through air separation and is primarily stored as a liquid or compressed gas. Generation and storage of oxygen for use in fuel cells in self-contained underwater vehicles is particularly difficult due to the absence of airand the need to limit space and weight. There is a need for development of a dense controllable oxygen source for such applications. An alterna ...

In Phase I CTI demonstrated an innovative, frequency-agile laser source that could tune throughout the midwave infrared spectral region (4-6 um). The source was based on a Cr:ZnSe laser pumping a ZnGeP2 optical parametric oscillator (OPO). Advantages ofthis system include that both the laser and OPO operate well at room-temperature with only passive cooling, the system is amendable to power scal ...

Active imaging in the short- and mid-wave infrared has well-known benefits versus shorter wavelengths: eye safety, better visibility through battlefield obscurants, high atmospheric trans-mission, and reduced background emission. However, there are nosuitable imaging detectors at eye-safe wavelengths. CTI proposes a nonlinear sum-frequency generator (SFG) to convert an image at 1.55 mm to a shorte ...

In the Phase I study, a protype instrument, the aerosolvaporization spectrometer (AVS)was evaluated for the ability toclassify airborne aerosol particles by their incandescentsignal. The instrument uses a diode pumped Nd:YAG laser at 1.06u wavelength to excite the particles. The scattering signal ismonitored from all particles, and black carbon particles absorbsufficient energy to incandesce, and ...

Droplet Measurement Technologies, Inc. proposes to demonstrate the viability of a newtechnique for measuring carbon mass on a particle-by-particle basis. The methodologyutilizes a combination of light scattering and emission to differentiate carbonaerosolsfrom other types of particles and quantify the mass of these particles overa size range from 0.05 micrometers to greater than 5 micrometers. The ...

Engineered Coatings, Inc. (ECI) proposes in Phase II to scale and demonstrate, on hardware components, a novel thin-film composite coating technology that will offer improved fretting wear resistance for moving mechanical components in U.S. Navy aircraftapplications. Based upon the technical feasibility (low friction, low wear, and galling resistance) demonstrated in the Phase I program for TiC & ...

This Phase II effort will research, develop, and evaluate a prototype SuperManual, a personally adaptive electronic maintenance manual (IETM) that is automatically constructed from ordinary manuals. It will accomplish this by combining and advancing twostate-of-art technologies for adaptive text search and presentation. (1) Latent Semantic Analysis (LSA), an automatic machine-learning technology t ...

The Advanced Distributed Learning infrastructure will greatly expand the opportunity to use computer based training (CBT). Comparable opportunities are rapidly increasing in corporate training, institutional education, and individual life-longlearning.However, the development of a high quality CBT requires both subject matter and instructional design expertise, which are seldom found in the same p ...
