Soldering electronic components to circuit boards involves using environmentally harmful cleaning agents and toxic heavy metals like lead. Solder joints can be unreliable in high shock environments because of non-uniform adhesion. This program will develop an entirely new method for welding such joints. In this novel method, 50-500 nm diam monodisperse droplets of high temperature filler metal are ...

The application of modernComputer Assisted Engineering (CASE) tools is proposed to address the development of the decision support system architecture concpet. This technique has been applied to similarky complex and interrelated large-scale ehterprises, in which inputs from a very large diverity of data sources must be appropriately integrated and modeled. APJ has demonstrated the viability of st ...

The application of modern Computer Aided System Engineering (CASE) tools, coupled with object oriented programming and the full exploitation of modern AI techniques and graphics technology is proposed to develop a simulation architecture that will address the Army's logistics and sustainment systems from the industrial base to the individual weapon system user. The APJ technique can address logist ...

This project will analyze and select promising materials and designs to be used in the plumes of tactical solid rocket motors for missile steering and control. The emphasis is on high-performance refractory materials and compatibility of material systems. The control fins experience severe thermal and severe particulate erosion environments. Missile controllability requires fins with minimal er ...

THIS PROJECT ADDRESSES SYSTEMS TO REDUCE NOISE AND VIBRATIONS EMANATING FROM AUXILIAIY POWER UNITS (APUS) WHICH ARE BEING INITEGRATED INTO ARMY VEHICLES AND SHELTERS. EXCESSIVE NOISE AND VIBRATIONS ARE HARMFUL TO AND HINDER THE EFFECTIVENESS OF OPERATORS AND OCCUPANTS. IN MILITARY EQUIPMENT, IT IS ALSO BENEFICIAL TO AVOID EMANATIONS THAT MIGHT BE USED AS DETECTION SIGNATURES . THIS EXPLORATORY DEV ...

ARMY NATICK RESEARCH HAS FOUND THAT A SUPERACTIVATED CARBON WITH BET SURFACE AREAS GREATER THAN 3000 METERS SQUARED PER GRAM HAS POTENTIAL APPLICATION IN THE PRODUCTION OF SUPERIOR CHEMICAL PROTECTION EQUIPMENT FOR BATTLEFIELD PERSONNEL. THIS CARBON, ORIGINALLY DEVELOPED BY AMOCO CORPORATION, IS PRODUCED BY A UNIQUE HIGH TEMPERATURE CAUSTIC ACTIVATION PROCESS AND IS NOT CURRENTLY AVAILABLE FROM DO ...

Modeling and simulation (M&S) provides the potential of serving as a cost-effective expedient for developing, acquiring, testing, and fielding new technologies for the future battlefield-provided the limitations of existing tools and techniques can be overcome. As the Army focal point for communications M&S, the U.S. Army Communications-Electronic Command (CECOM) has the lead for performing M&S t ...

MILITARY SYSTEMS POWERED BY INTERNAL COMBUSTION ENGINES EMIT NOISE FROM THE EXHAUST SYSTEM. THERE ARE TWO TYPES OF NOISE, AIRBORNE, DUE TO THE PRESSURE WAVE PROPAGATING THROUGH THE EXHAUST SYSTEM AND EXITING AT THE OUTLET AND STRUCTURE - BORNE, RADIATED FROM THE VIBRATING COMPONENTS OF THE EXHAUST SYSTEM. THE OBJECTIVE OF THIS PROJECT IS TO DEVELOP A COMPUTER CODE SIMULATING THE EXHAUST SYSTEM, AN ...
