The SKATE concept was designed to quantify skill levels of trainees, teams, or units, generate skill-appropriate training scenarios, and provide a continuous skill-level assessment of disparately skilled trainees, teams, and units in a joint training exercise while maintaining the overall integrity and realism of the mission itself. SKATE evaluates the skill level of an individual, teams, or unit ...

This proposal describes an approach to realize InAs/GaSb type II superlattice focal plane arrays through planar processing. A problem with conventional mesa diode processing approaches is that nonradiative surface recombination at the exposed pn junction is extremely rapid, leading to surface leakage currents that limit the mesa diode performance. By eliminating etched sidewalls through planar p ...

Energy harvesting devices utilizing magnetostrictive materials are a logical choice for harvesting the high impedance (high force, low displacement) vibrations found aboard Navy ships. Force-based devices, enabled by magnetostrictive materials, can harvest energy over an extremely large bandwidth, approximately ±35 and ±70 Hz currently, making them more desirable in situations aboard Navy ships ...

The objective of this program is to develop techniques to reduce engine cooling system noise levels of the Expeditionary Fighting Vehicle (EFV). Mezzo’s approach is to redesign the engine cooling heat exchangers (LTC, HTC, fuel cooler, and condenser) using Mezzo’s heat exchanger technology to reduce the overall heat exchanger pressure drop and thus the demands on the cooling fans. Reduced pres ...

Mezzo fabricates high performance micro tube heat exchangers. In the Phase I program, Mezzo explored substituting the stainless steel micro tubes that typically have been used with polymer micro tubes. Polymer micro tube heat exchangers have significant potential advantages over currently used metal plate-fin heat exchanger technologies. Specifically, polymer micro tube heat exchangers provide ext ...

The aerodynamic performance of aircraft is significantly impacted by the aero-elastic dynamics of its control surfaces. In particular, the dynamics of flutter - an unstable self-excitation of structure due to undesirable coupling of structural flexibility and aerodynamics - has critical impact on the stability and performance of aircraft. The control surface flutter characteristics are affected by ...

BMB Discount Guns, Ammunition, and Supplies proposes to develop a novel form of dim tracer ammunition. This ammunition is a non-burning, chemically inert, constant mass tracer. This design of this dim tracer is such that it cannot be perceived by enemy forces, even with enhanced optics. This ammunition can be manufactured with masses substantially identical to ball ammunition. By matching the ...

THE GENERAL PURPOSE ICE DETECTOR/ACCUMULATOR PROPOSED IN THIS DOCUMENT EMPLOYS TWO ULTRASONIC SENSING MODES. RAYLEIGH WAVES (SURFACE WAVES) ARE USED TO DETECT THE ONSET OF ICING, AND TIME-OFFLIGHT MEASUREMENTS IN A NORMAL INCIDENT REFLECTION OF ULTRASONIC PULSES FROM THE ICE LAYERS ARE USED FOR MEASURING APPRECIALBE BUILDUP THICKNESS OF THE ICE (>0.5MM). THE BASIC PRINCIPLES UNDERLYING A TIME-OF-F ...

A COMBINED EXPERIMENTAL AND ANALYTICAL STUDY IS PLANNED TO DEVELOP ADVANCED COMPOSITE PIPING SYSTEMS. DUAL WALL PIPE WILL BE DEVELOPED AND TESTED FOR IMPROVED IMPACT RESISTANCE AND TOUGHNESS. EPOXY AND POLYESTER RESINS WILL BE USED IN COMPOSITE PIPE SECTIONS AND BONDED WITH EPOXY ADHESIVES AS WELL AS WITH HEAT-SHRINKABLE ULTRA HIGH MOLECULAR WEIGHT POLYETHYLENE AND ADVANCED ELASTMERIC COUPLINGS AN ...

TECHNOLOGY INTERNATIONAL INCORPORATED (TII) IS PROPOSING THE CONSTRUCTION OF A DETECTABLE DEFECT DRIFT DIFFUSION (D4) MODEL FOR PREDICTION OF HELICOPTER GEARBOX LIFE EXPECTANCY. THE MODELING STRATEGY IS BASED ON PREDICTING FATIGUE OF TYPICAL MECHANICAL EQUIPMENT WITH ROLLING CONTACT, SUCH AS ROLLING ELEMENT BEARING AND GEAR OF THE HELICOPTER GEARBOX. THE RATE OF GROWTH OF SPECIFIC SIZES AND TYPES ...
