Standard U.S. Navy fiber optic assemblies require that the fiber be bonded to the connector using an adhesive that is labor intensive and heat controlled (MIL-A-24792). Advanced Material Systems (AMS) proposes a study that could solve this problem through the development of an adhesive system that would cure at room temperature in less that 3 minutes and yet meet all of the in-service req ...

Recent trends in submarine design indicate the need for-locating more electrical components, such as propulsion motors and actuators, outside the pressure hull. As a result, there is a need for electrical hull penetrators/connectors which can transfer high currents or high voltages through the submarine's pressure hull. We propose to review the capabilities and limitations of existing penetrator/ ...

Enemy forces can be crippled quickly at the beginning of a war by separating the enemies command and control structure from its combat forces and other elements of its defensive network. A false target generator has the potential to saturate or tie up an enemies air defense net and increase survivability of our own airborne assets. An unmanned aerial vehicle (UAV) is an optimum candidate for a dec ...

Advanced anti-radiation missiles using large, high temperature superconducting antennas will require cryocoolers that can cool the antenna quickly with a minimum mass and volume penalty. We will develop a mixed gas Joule-Thomson (J-T) cryocooler with the load heat exchanger integral to the antenna substrate. The mixed gas J-T thermodynamic cycle is significantly more efficient than current singl ...

Current ultrasound images in mine warfare, biomedical imaging and non-destructive testing are limited by the use of linear transducer arrays which result in thick image "slices", errors from phase aberrations and primitive volumetric scanning capability. Two-dimensional arrays will overcome these limitations. Two-dimensional arrays have not been manufactured because of difficulty in fabricating t ...

An acoustic/ultrasonic sensor development program is proposed for non-invasive determination of the amount of scale in shipboard sewage pipes and fluid level in shipboard sewage tanks. The technology is based on speed, attenuation, and scattering of vibrational waves (acoustic/ultrasonic/elastic) propagating in or through tanks and pipes are sensitive to the materials inside. By measuring the ch ...

Standard Object Systems, Inc. proposes the adaptati on of its Standard Objects for Phonetic Speech Recognition software to the development of a Software Package for Speaker Independent or Dependent Continuous Speech Recognition. This application supports both speaker independent and dependent connected word recognition with adaptation to multi lingual and multi accent envir ...

Today, the majority of sandwich structures on aircraft involve a honeycomb and/or foam core with adhesive bonded face sheets. But, there are problems associated with conventionally cored composites. Honeycomb cored composites are expensive and vulnerable to a variety of environmental threats and shortcomings. These include moisture absorption, internal corrosion, shin-to-core disbonds, shin bulg ...
